I'm interested in all knowledge, especially how to organize it so you can find whatever is most relevant at any given moment.
I've been around Misplaced Pages since the Fall of 2005, and have been working mostly on Misplaced Pages's structure, and its knowledge navigation systems, throughout that time.
Scraping a web page involves fetching it and then extracting data from it. Fetching is the downloading of a page (which a browser does when a user views a page). Therefore, web crawling is a main component of web scraping, to fetch pages for later processing. Having fetched, extraction can take place. The content of a page may be parsed, searched and reformatted, and its data copied into a spreadsheet or loaded into a database. Web scrapers typically take something out of a page, to make use of it for another purpose somewhere else. An example would be finding and copying names and telephone numbers, companies and their URLs, or e-mail addresses to a list (contact scraping).
Web pages are built using text-based mark-up languages (HTML and XHTML), and frequently contain a wealth of useful data in text form. However, most web pages are designed for human end-users and not for ease of automated use. As a result, specialized tools and software have been developed to facilitate the scraping of web pages. Web scraping applications include market research, price comparison, content monitoring, and more. Businesses rely on web scraping services to efficiently gather and utilize this data.

Image 4Health has a variety of definitions, which have been used for different purposes over time. In general, it refers to physical and emotional well-being, especially that associated with normal functioning of the human body, absent of disease, pain (including mental pain), or injury.
Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disorders. (Full article...)
Image 5 A severe case of athlete's foot. Athlete's foot, known medically as tinea pedis, is a common skin infection of the feet caused by a fungus. Signs and symptoms often include itching, scaling, cracking and redness. In rare cases the skin may blister. Athlete's foot fungus may infect any part of the foot, but most often grows between the toes. The next most common area is the bottom of the foot. The same fungus may also affect the nails or the hands. It is a member of the group of diseases known as tinea.
Athlete's foot is caused by a number of different funguses, including species of Trichophyton, Epidermophyton, and Microsporum. The condition is typically acquired by coming into contact with infected skin, or fungus in the environment. Common places where the funguses can survive are around swimming pools and in locker rooms. They may also be spread from other animals. Usually diagnosis is made based on signs and symptoms; however, it can be confirmed either by culture or seeing hyphae using a microscope.
Athlete's foot is not limited to just athletes: it can be caused by going barefoot in public showers, letting toenails grow too long, wearing shoes that are too tight, or not changing socks daily. It can be treated with topical antifungal medications such as clotrimazole or, for persistent infections, using oral antifungal medications such as terbinafine. Topical creams are typically recommended to be used for four weeks. Keeping infected feet dry and wearing sandals also assists with treatment.
Athlete's foot was first medically described in 1908. Globally, athlete's foot affects about 15% of the population. Males are more often affected than females. It occurs most frequently in older children or younger adults. Historically it is believed to have been a rare condition that became more frequent in the 20th century due to the greater use of shoes, health clubs, war, and travel. (Full article...)
Visceral fat, also known as organ fat or intra-abdominal fat, is located inside the peritoneal cavity, packed in between internal organs and torso, as opposed to subcutaneous fat, which is found underneath the skin, and intramuscular fat, which is found interspersed in skeletal muscle. Visceral fat is composed of several adipose depots including mesenteric, epididymal white adipose tissue (EWAT), and perirenal fat. An excess of adipose visceral fat is known as central obesity, the "pot belly" or "beer belly" effect, in which the abdomen protrudes excessively. This body type is also known as "apple shaped", as opposed to "pear shaped" in which fat is deposited on the hips and buttocks.
Researchers first started to focus on abdominal obesity in the 1980s when they realized it had an important connection to cardiovascular disease, diabetes, and dyslipidemia. Abdominal obesity was more closely related with metabolic dysfunctions connected with cardiovascular disease than was general obesity. In the late 1980s and early 1990s insightful and powerful imaging techniques were discovered that would further help advance the understanding of the health risks associated with body fat accumulation. Techniques such as computed tomography and magnetic resonance imaging made it possible to categorize mass of adipose tissue located at the abdominal level into intra-abdominal fat and subcutaneous fat.

Image 8Visualization of various methodological approaches to gaining insights from meta data areas
Information science is an academic field which is primarily concerned with analysis, collection, classification, manipulation, storage, retrieval, movement, dissemination, and protection of information. Practitioners within and outside the field study the application and the usage of knowledge in organizations in addition to the interaction between people, organizations, and any existing information systems with the aim of creating, replacing, improving, or understanding the information systems.
Image 9A revenue model is a framework for generating financial income. There can be a variety of ways for revenue generation such as the production model, manufacturing model, as well as the construction model. A revenue model identifies which revenue source to pursue, what value to offer, how to price the value, and whopays for the value. It is a key component of a company's business model. A revenue model primarily identifies what product or service will be created and sold in order to generate revenues.
Without a clear and well-defined revenue model new businesses will be more likely to struggle. By having a clear revenue model, a business can focus on a target audience, fund development plans for a product or service, establish marketing plans, open a line of credit and raise capital.

One argument for the importance of this risk references how human beings dominate other species because the human brain possesses distinctive capabilities other animals lack. If AI were to surpass human intelligence and become superintelligent, it might become uncontrollable. Just as the fate of the mountain gorilla depends on human goodwill, the fate of humanity could depend on the actions of a future machine superintelligence.
The plausibility of existential catastrophe due to AI is widely debated. It hinges in part on whether AGI or superintelligence are achievable, the speed at which dangerous capabilities and behaviors emerge, and whether practical scenarios for AI takeovers exist. Concerns about superintelligence have been voiced by computer scientists and tech CEOs such as Geoffrey Hinton, Yoshua Bengio, Alan Turing, Elon Musk, and OpenAI CEO Sam Altman. In 2022, a survey of AI researchers with a 17% response rate found that the majority believed there is a 10 percent or greater chance that human inability to control AI will cause an existential catastrophe. In 2023, hundreds of AI experts and other notable figures signed a statement declaring, "Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war". Following increased concern over AI risks, government leaders such as United Kingdom prime ministerRishi Sunak and United Nations Secretary-GeneralAntónio Guterres called for an increased focus on global AI regulation.
Two sources of concern stem from the problems of AI control and alignment. Controlling a superintelligent machine or instilling it with human-compatible values may be difficult. Many researchers believe that a superintelligent machine would likely resist attempts to disable it or change its goals as that would prevent it from accomplishing its present goals. It would be extremely challenging to align a superintelligence with the full breadth of significant human values and constraints. In contrast, skeptics such as computer scientistYann LeCun argue that superintelligent machines will have no desire for self-preservation. (Full article...)
Image 11Genius is a characteristic of original and exceptional insight in the performance of some art or endeavor that surpasses expectations, sets new standards for the future, establishes better methods of operation, or remains outside the capabilities of competitors. Genius is associated with intellectual ability and creative productivity. The term genius can also be used to refer to people characterised by genius, and/or to polymaths who excel across many subjects.
There is no scientifically precise definition of genius. When used to refer to the characteristic, genius is associated with talent, but several authors such as Cesare Lombroso and Arthur Schopenhauer systematically distinguish these terms. Walter Isaacson, biographer of many well-known geniuses, explains that although high intelligence may be a prerequisite, the most common trait that actually defines a genius may be the extraordinary ability to apply creativity and imaginative thinking to almost any situation.
In the early-19th century Carl von Clausewitz, who had a particular interest in what he called "military genius", defined "the essence of Genius" (German: der Genius) in terms of "a very high mental capacity for certain employments". (Full article...)
LCC has been criticized for lacking a sound theoretical basis; many of the classification decisions were driven by the practical needs of that library rather than epistemological considerations. Although it divides subjects into broad categories, it is essentially enumerative in nature. That is, it provides a guide to the books actually in one library's collections, not a classification of the world. (Full article...)
Image 13The technological singularity—or simply the singularity—is a hypothetical future point in time at which technological growth becomes uncontrollable and irreversible, resulting in unforeseeable consequences for human civilization. According to the most popular version of the singularity hypothesis, I. J. Good's intelligence explosion model of 1965, an upgradable intelligent agent could eventually enter a positive feedback loop of self-improvement cycles, each successive; and more intelligent generation appearing more and more rapidly, causing a rapid increase ("explosion") in intelligence which would ultimately result in a powerful superintelligence, qualitatively far surpassing all human intelligence.
The Hungarian-American mathematician John von Neumann (1903-1957) became the first known person to use the concept of a "singularity" in the technological context.
Alan Turing, often regarded as the father of modern computer science, laid a crucial foundation for the contemporary discourse on the technological singularity. His pivotal 1950 paper, "Computing Machinery and Intelligence," introduces the idea of a machine's ability to exhibit intelligent behavior equivalent to or indistinguishable from that of a human.
Stanislaw Ulam reported in 1958 an earlier discussion with von Neumann "centered on the accelerating progress of technology and changes in human life, which gives the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue". Subsequent authors have echoed this viewpoint. (Full article...)
Image 14The branches of science, also referred to as sciences, scientificfields or scientific disciplines, are commonly divided into three major groups:
Scientific knowledge must be grounded in observable phenomena and must be capable of being verified by other researchers working under the same conditions.
Image 15Artificial general intelligence (AGI) is a type of artificial intelligence (AI) that matches or surpasses human cognitive capabilities across a wide range of cognitive tasks. This contrasts with narrow AI, which is limited to specific tasks. Artificial superintelligence (ASI), on the other hand, refers to AGI that greatly exceeds human cognitive capabilities. AGI is considered one of the definitions of strong AI.
Creating AGI is a primary goal of AI research and of companies such as OpenAI and Meta. A 2020 survey identified 72 active AGI research and development projects across 37 countries.
The timeline for achieving AGI remains a subject of ongoing debate among researchers and experts. As of 2023, some argue that it may be possible in years or decades; others maintain it might take a century or longer; a minority believe it may never be achieved; and another minority claims that it is already here. Notable AI researcher Geoffrey Hinton has expressed concerns about the rapid progress towards AGI, suggesting it could be achieved sooner than many expect.
Image 16A superintelligence is a hypothetical agent that possesses intelligence surpassing that of the brightest and most gifted human minds. "Superintelligence" may also refer to a property of problem-solving systems (e.g., superintelligent language translators or engineering assistants) whether or not these high-level intellectual competencies are embodied in agents that act in the world. A superintelligence may or may not be created by an intelligence explosion and associated with a technological singularity.
University of Oxford philosopher Nick Bostrom defines superintelligence as "any intellect that greatly exceeds the cognitive performance of humans in virtually all domains of interest". The program Fritz falls short of this conception of superintelligence—even though it is much better than humans at chess—because Fritz cannot outperform humans in other tasks.
Technological researchers disagree about how likely present-day human intelligence is to be surpassed. Some argue that advances in artificial intelligence (AI) will probably result in general reasoning systems that lack human cognitive limitations. Others believe that humans will evolve or directly modify their biology to achieve radically greater intelligence. Several future study scenarios combine elements from both of these possibilities, suggesting that humans are likely to interface with computers, or upload their minds to computers, in a way that enables substantial intelligence amplification.
Some researchers believe that superintelligence will likely follow shortly after the development of artificial general intelligence. The first generally intelligent machines are likely to immediately hold an enormous advantage in at least some forms of mental capability, including the capacity of perfect recall, a vastly superior knowledge base, and the ability to multitask in ways not possible to biological entities. This may allow them to — either as a single being or as a new species — become much more powerful than humans, and displace them. (Full article...)
Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, earth science, and astronomy. These branches of natural science may be further divided into more specialized branches (also known as fields). As empirical sciences, natural sciences use tools from the formal sciences, such as mathematics and logic, converting information about nature into measurements that can be explained as clear statements of the "laws of nature".
Modern natural science succeeded more classical approaches to natural philosophy. Galileo, Kepler, Descartes, Bacon, and Newton debated the benefits of using approaches which were more mathematical and more experimental in a methodical way. Still, philosophical perspectives, conjectures, and presuppositions, often overlooked, remain necessary in natural science. Systematic data collection, including discovery science, succeeded natural history, which emerged in the 16th century by describing and classifying plants, animals, minerals, and so on. Today, "natural history" suggests observational descriptions aimed at popular audiences. (Full article...)
The same terminology can be used with the term "sentience" instead of "consciousness" when specifically designating phenomenal consciousness (the ability to feel qualia). Since sentience involves the ability to experience ethically positive or negative (i.e., valenced) mental states, it may justify welfare concerns and legal protection, as with animals.
Some scholars believe that consciousness is generated by the interoperation of various parts of the brain; these mechanisms are labeled the neural correlates of consciousness or NCC. Some further believe that constructing a system (e.g., a computer system) that can emulate this NCC interoperation would result in a system that is conscious. (Full article...)
Image 19Prehistoric technology is technology that predates recorded history. History is the study of the past using written records. Anything prior to the first written accounts of history is prehistoric, including earlier technologies. About 2.5 million years before writing was developed, technology began with the earliest hominids who used stone tools, which they first used to hunt food, and later to cook.
There are several factors that made the evolution of prehistoric technology possible or necessary. One of the key factors is behavioral modernity of the highly developed brain of Homo sapiens capable of abstract reasoning, language, introspection, and problem-solving. The advent of agriculture resulted in lifestyle changes from nomadic lifestyles to ones lived in homes, with domesticated animals, and land farmed using more varied and sophisticated tools. Art, architecture, music and religion evolved over the course of the prehistoric periods. (Full article...)
Image 20A userscript (or user script) is a program, usually written in JavaScript, for modifying web pages to augment browsing. Uses include adding shortcut buttons and keyboard shortcuts, controlling playback speeds, adding features to sites, and enhancing the browsing history.
On desktop browsers such as Firefox, userscripts are enabled by use of a userscript managerbrowser extension such as Tampermonkey or Greasemonkey. The Presto-based Opera-supported userscripts (referred to as User JavaScript) are placed in a designated directory. Userscripts are often referred to as Greasemonkey scripts, named after the original userscript manager for Firefox.
On Misplaced Pages, a user scripts feature is enabled for registered users that allows them to install userscripts to augment editing and viewing of the encyclopedia's pages. (Full article...)
Image 21Moore's law is an example of futurology; it is a statistical collection of past and present trends with the goal of accurately extrapolating future trends. Futures studies, futures research, futurism research, futurism, or futurology is the systematic, interdisciplinary and holistic study of social/technological advancement, and other environmental trends; often for the purpose of exploring how people will live and work in the future. Predictive techniques, such asforecasting, can be applied, but contemporary futures studies scholars emphasize the importance of systematically exploring alternatives. In general, it can be considered as a branch of thesocial sciences and an extension to the field of history. Futures studies (colloquially called "'futures" by many of the field's practitioners) seeks to understand what is likely to continue and what could plausibly change. Part of the discipline thus seeks a systematic and pattern-based understanding of past and present, and to explore the possibility of future events and trends.
Unlike the physical sciences where a narrower, more specified system is studied, futurology concerns a much bigger and more complex world system. The methodology and knowledge are much less proven than in natural science and social sciences like sociology and economics. There is a debate as to whether this discipline is an art or science, and it is sometimes described as pseudoscience; nevertheless, the Association of Professional Futurists was formed in 2002, developing a Foresight Competency Model in 2017, and it is now possible to study it academically, for example at the FU Berlin in their master's course. To encourage inclusive and cross-disciplinary discussions about futures studies, UNESCO declared December 2 as World Futures Day. (Full article...)
A taxonomy (or taxonomical classification) is a scheme of classification, especially, a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are.
Manually developing and maintaining a taxonomy is a labor-intensive task requiring significant time and resources, including familiarity of or expertise in the taxonomy's domain (scope, subject, or field), which drives the costs and limits the scope of such projects. Also, domain modelers have their own points of view which inevitably, even if unintentionally, work their way into the taxonomy. ATC uses artificial intelligence techniques to quickly automatically generate a taxonomy for a domain in order to avoid these problems and remove limitations. (Full article...)
Image 23Types of democracy refers to the various governance structures that embody the principles of democracy ("rule by the people") in some way. Democracy is frequently applied to governments (ranging from local to global), but may also be applied to other constructs like workplaces, families, community associations, and so forth.
Types of democracy can cluster around values. Some such types, defined as direct democracy (or participatory democracy, or deliberative democracy), promote equal and direct participation in political decisions by all members of the public. Others, including the many variants of representative democracy, favor more indirect or procedural approaches to collective self-governance, where decisions are made by elected representatives rather than by the people directly.
Types of democracy can be found across time, space, and language. The foregoing examples are just a few of the thousands of refinements of, and variations on, the central notion of "democracy." (Full article...)
Image 24Etruscan: Diomedes and Polyxena, from the Etruscan amphora of the Pontic group, c. 540–530 BCE – From Vulci Ceramic art is art made from ceramic materials, including clay. It may take varied forms, including artistic pottery, including tableware, tiles, figurines and other sculpture. As one of the plastic arts, ceramic art is a visual art. While some ceramics are considered fine art, such as pottery or sculpture, most are considered to be decorative, industrial or applied art objects. Ceramic art can be created by one person or by a group, in a pottery or a ceramic factory with a group designing and manufacturing the artware.
In Britain and the United States, modern ceramics as an art took its inspiration in the early twentieth century from the Arts and Crafts movement, leading to the revival of pottery considered as a specifically modern craft. Such crafts emphasized traditional non-industrial production techniques, faithfulness to the material, the skills of the individual maker, attention to utility, and an absence of excessive decoration that was typical to the Victorian era.
The word "ceramics" comes from the Greek keramikos (κεραμεικός), meaning "pottery", which in turn comes from keramos (κέραμος) meaning "potter's clay". Most traditional ceramic products were made from clay (or clay mixed with other materials), shaped and subjected to heat, and tableware and decorative ceramics are generally still made this way. In modern ceramic engineering usage, ceramics is the art and science of making objects from inorganic, non-metallic materials by the action of heat. It excludes glass and mosaic made from glass tesserae.
There is a long history of ceramic art in almost all developed cultures, and often ceramic objects are all the artistic evidence left from vanished cultures, like that of the Nok in Africa over 2,000 years ago. Cultures especially noted for ceramics include the Chinese, Cretan, Greek, Persian, Mayan, Japanese, and Korean cultures, as well as the modern Western cultures. (Full article...)

On the left is a Mars Exploration Rover (MER) test vehicle that is a working sibling to Spirit and Opportunity, which landed on Mars in 2004. On the right is a test rover for the Mars Science Laboratory, which landed Curiosity on Mars in 2012.
The goal of most robotics is to design machines that can help and assist humans. Many robots are built to do jobs that are hazardous to people, such as finding survivors in unstable ruins, and exploring space, mines and shipwrecks. Others replace people in jobs that are boring, repetitive, or unpleasant, such as cleaning, monitoring, transporting, and assembling. Today, robotics is a rapidly growing field, as technological advances continue; researching, designing, and building new robots serve various practical purposes. (Full article...)

Image 1Biological immortality (sometimes referred to as bio-indefinite mortality) is a state in which the rate of mortality from senescence (or aging) is stable or decreasing, thus decoupling it from chronological age. Various unicellular and multicellular species, including some vertebrates, achieve this state either throughout their existence or after living long enough. A biologically immortal living being can still die from means other than senescence, such as through injury, poison, disease, predation, lack of available resources, or changes to environment.
This definition of immortality has been challenged in the Handbook of the Biology of Aging, because the increase in rate of mortality as a function of chronological age may be negligible at extremely old ages, an idea referred to as the late-life mortality plateau. The rate of mortality may cease to increase in old age, but in most cases that rate is typically very high. (Full article...)
Image 2Diagram of the most basic resonant inductive coupling wireless power transfer system. This is called 2nd-resonance technology. Resonant inductive coupling or magnetic phase synchronous coupling is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. A resonant transformer of this type is often used in analog circuitry as a bandpass filter. Resonant inductive coupling is also used in wireless power systems for portable computers, phones, and vehicles. (Full article...)
Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate some realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a head-mounted display with a small screen in front of the eyes, but can also be created through specially designed rooms with multiple large screens. Virtual reality typically incorporates auditory and video feedback, but may also allow other types of sensory and force feedback through haptic technology. (Full article...)

Image 7[REDACTED] GeForce Now (stylized as GeForce NOW) is the brand used by Nvidia for its cloud gaming service. The Nvidia Shield version of GeForce Now, formerly known as Nvidia Grid, launched in beta in 2013, with Nvidia officially unveiling its name on September 30, 2015. The subscription service provided users with unlimited access to a library of games hosted on Nvidia servers for the life of the subscription, being delivered to subscribers through streaming video. Certain titles were also available via a "Buy & Play" model. This version was discontinued in 2019, and transitioned to a new version of the service that enabled Shield users to play their own games.
In January 2017, Nvidia unveiled GeForce Now clients for Windows and Mac computers, available in North America and Europe as a free beta. GeForce NOW lets users access a virtual computer, where they can install their existing games from existing digital distribution platforms, and play them remotely. As with the original Shield version, the virtual desktop is also streamed from Nvidia servers. An Android client was also introduced in 2019. (Full article...)
Image 8Phase-change memory (also known as PCM, PCME, PRAM, PCRAM, OUM (ovonic unified memory) and C-RAM or CRAM (chalcogenide RAM)) is a type of non-volatile random-access memory. PRAMs exploit the unique behaviour of chalcogenide glass. In PCM, heat produced by the passage of an electric current through a heating element generally made of titanium nitride is used to either quickly heat and quench the glass, making it amorphous, or to hold it in its crystallization temperature range for some time, thereby switching it to a crystalline state. PCM also has the ability to achieve a number of distinct intermediary states, thereby having the ability to hold multiple bits in a single cell, but the difficulties in programming cells in this way has prevented these capabilities from being implemented in other technologies (most notably flash memory) with the same capability.
Recent research on PCM has been directed towards attempting to find viable material alternatives to the phase-change materialGe2Sb2Te5 (GST), with mixed success. Other research has focused on the development of a GeTe–Sb2Te3superlattice to achieve non-thermal phase changes by changing the co-ordination state of the germanium atoms with a laser pulse. This new Interfacial Phase-Change Memory (IPCM) has had many successes and continues to be the site of much active research. (Full article...)
Image 9Concept art of hyperloop inner workings
Hyperloop is a proposed high-speed transportation system for both passengers and freight. The concept behind the Hyperloop originated in the late 17th century with the invention of the world's first artificial vacuum, which led to designs for underground rapid transit systems powered by pneumatics in the decades that followed. In 1799, inventor George Medhurst proposed the idea to move goods through cast-iron pipes using air pressure and in 1844 built a railway station (for passenger carriages) in London that relied on pneumatics until 1847. In 2013, entrepreneur Elon Musk published a white paper, where the hyperloop was described as a transportation system using capsules supported by an air-bearing surface within a low-pressure tube. Hyperloop systems have three essential elements: tubes, pods, and terminals. The tube is a large, sealed low-pressure system (typically a long tunnel). The pod is a coach at atmospheric pressure that experiences low air resistance or friction inside the tube using magnetic propulsion (in the initial design, augmented by a ducted fan). The terminal handles pod arrivals and departures. The hyperloop, in the form proposed by Musk, differs from traditional vactrains by relying on residual air pressure inside the tube to provide lift from aerofoils and propulsion by fans; however, many subsequent variants using the name "hyperloop" have remained relatively close to the core principles of vactrains.
Hyperloop was teased by Elon Musk at a 2012 speaking event, and described as a "fifth mode of transport". Musk released details of an alpha-version in a white paper on 22 August 2013, in which the hyperloop design incorporated reduced-pressure tubes with pressurized capsules riding on air bearings driven by linear induction motors and axial compressors. The white paper showed an example hyperloop route running from the Los Angeles region to the San Francisco Bay Area, roughly following the Interstate 5 corridor. Some transportation analysts challenged the cost estimates in the white paper, with some predicting that a hyperloop would run several billion dollars higher. (Full article...)
Image 10American students learning how to make and roll sushi Learning is the process of acquiring new understanding, knowledge, behaviors, skills, values, attitudes, and preferences. The ability to learn is possessed by humans, non-human animals, and some machines; there is also evidence for some kind of learning in certain plants. Some learning is immediate, induced by a single event (e.g. being burned by a hotstove), but much skill and knowledge accumulate from repeated experiences. The changes induced by learning often last a lifetime, and it is hard to distinguish learned material that seems to be "lost" from that which cannot be retrieved.
Human learning starts at birth (it might even start before) and continues until death as a consequence of ongoing interactions between people and their environment. The nature and processes involved in learning are studied in many established fields (including educational psychology, neuropsychology, experimental psychology, cognitive sciences, and pedagogy), as well as emerging fields of knowledge (e.g. with a shared interest in the topic of learning from safety events such as incidents/accidents, or in collaborative learning health systems). Research in such fields has led to the identification of various sorts of learning. For example, learning may occur as a result of habituation, or classical conditioning, operant conditioning or as a result of more complex activities such as play, seen only in relatively intelligent animals. Learning may occur consciously or without conscious awareness. Learning that an aversive event cannot be avoided or escaped may result in a condition called learned helplessness. There is evidence for human behavioral learning prenatally, in which habituation has been observed as early as 32 weeks into gestation, indicating that the central nervous system is sufficiently developed and primed for learning and memory to occur very early on in development.

Aircraft of this type have no onboard human pilot. As the operator runs the vehicle from a remote terminal, equipment necessary for a human pilot is not needed, resulting in a lower weight and a smaller size than a manned aircraft. Many countries have operational domestic UCAVs, and many more have imported fighter drones or are in the process of developing them. (Full article...)
In 1997, Nokia launched Snake. Snake, which was pre-installed in most mobile devices manufactured by Nokia for a couple of years, has since become one of the most played games, at one point found on more than 350 million devices worldwide. Mobile devices became more computationally advanced allowing for downloading of games, though these were initially limited to phone carriers' own stores. Mobile gaming grew greatly with the development of app stores in 2008, such as the iOSApp Store from Apple. As the first mobile content marketplace operated directly by a mobile-platform holder, the App Store significantly changed the consumer behaviour and quickly broadened the market for mobile games, as almost every smartphone owner started to download mobile apps.

A backpack helicopter / helipack is a helicopter motor and rotor and controls assembly that can be strapped to a person's back, so they can walk about on the ground wearing it, and can use it to fly. It uses a harness like a parachute harness and should have a strap between the legs (so the pilot does not fall out of the harness during flight). Some designs may use a ducted fan design to increase upward thrust. Several inventors have tried to make backpack helicopters, with mixed results.
Typically, a backpack helicopter differs from a conventional helicopter in two main ways: (Full article...)
Image 17Atomic scale moiré pattern created by overlapping two skewed sheets of graphene, a hexagonal lattice composed of carbon atoms. Twistronics (from twist and electronics) is the study of how the angle (the twist) between layers of two-dimensional materials can change their electrical properties. Materials such as bilayer graphene have been shown to have vastly different electronic behavior, ranging from non-conductive to superconductive, that depends sensitively on the angle between the layers. The term was first introduced by the research group of Efthimios Kaxiras at Harvard University in their theoretical treatment of graphene superlattices.
Image 18The Holodeck is a fictional device from the television franchise Star Trek which uses "holograms" (projected light and electromagnetic energy which create the illusion of solid objects) to create a realistic 3D simulation of a real or imaginary setting, in which participants can freely interact with the environment as well as objects and characters, and sometimes a predefined narrative.
In several series, holodecks are an amenity available to the crew of starships. In the series Star Trek: Deep Space Nine, a similar device is referred to as a holosuite, operated by the owner of the space station's bar, Quark, who rents them out to customers. (Full article...)
Image 19State-of-the-art AWG for home use.
An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, or pressurizing the air. AWGs are useful where potable water is difficult to obtain, because water is always present in ambient air.
Image 20Diagram of an electrical grid (generation system in red, transmission system in blue, distribution system in green)
An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers. In that last step, voltage is stepped down again to the required service voltage. Power stations are typically built close to energy sources and far from densely populated areas. Electrical grids vary in size and can cover whole countries or continents. From small to large there are microgrids, wide area synchronous grids, and super grids. The combined transmission and distribution network is part of electricity delivery, known as the power grid.
Grids are nearly always synchronous, meaning all distribution areas operate with three phasealternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). This allows transmission of AC power throughout the area, connecting the electricity generators with consumers. Grids can enable more efficient electricity markets. (Full article...)
Image 21Emerging technologies are technologies whose development, practical applications, or both are still largely unrealized. These technologies are generally new but also include old technologies finding new applications. Emerging technologies are often perceived as capable of changing the status quo.
Emerging technologies are characterized by radical novelty (in application even if not in origins), relatively fast growth, coherence, prominent impact, and uncertainty and ambiguity. In other words, an emerging technology can be defined as "a radically novel and relatively fast growing technology characterised by a certain degree of coherence persisting over time and with the potential to exert a considerable impact on the socio-economic domain(s) which is observed in terms of the composition of actors, institutions and patterns of interactions among those, along with the associated knowledge production processes. Its most prominent impact, however, lies in the future and so in the emergence phase is still somewhat uncertain and ambiguous." (Full article...)
Image 22General concept for TDMR using multiple read elements
Two-dimensional magnetic recording (TDMR) is a technology introduced in 2017 in hard disk drives (HDD) used for computer data storage. Most of the world's data is recorded on HDDs, and there is continuous pressure on manufacturers to create greater data storage capacity in a given HDD form-factor and for a given cost. In an HDD, data is stored using magnetic recording on a rotating magnetic disk and is accessed through a write-head and read-head (or read-element). TDMR allows greater storage capacity by advantageously combining signals simultaneously from multiple read-back heads to enhance the recovery of one or more data-tracks. In this manner, data can be stored with higher areal-density on the disks thus providing higher capacity in each HDD. TDMR is a read-back technology and thus applies equally well to future recording (writing) technologies such as heat-assisted magnetic recording (HAMR) and microwave-assisted magnetic recording (MAMR).

In most countries, such trade represents a significant share of gross domestic product (GDP). While international trade has existed throughout history (for example Uttarapatha, Silk Road, Amber Road, salt roads), its economic, social, and political importance has been on the rise in recent centuries.
Carrying out trade at an international level is a complex process when compared to domestic trade. When trade takes place between two or more states, factors like currency, government policies, economy, judicial system, laws, and markets influence trade. (Full article...)
Virtually all civilizations have suffered such a fate, regardless of their size or complexity. Most never recovered, such as the Western and Eastern Roman Empires, the Maya civilization, and the Easter Island civilization. However, some of them later revived and transformed, such as China, Greece, and Egypt.
Anthropologists, historians, and sociologists have proposed a variety of explanations for the collapse of civilizations involving causative factors such as environmental degradation, depletion of resources, costs of rising complexity, invasion, disease, decay of social cohesion, growing inequality, extractive institutions, long-term decline of cognitive abilities, loss of creativity, and misfortune. However, complete extinction of a culture is not inevitable, and in some cases, the new societies that arise from the ashes of the old one are evidently its offspring, despite a dramatic reduction in sophistication. Moreover, the influence of a collapsed society, such as the Western Roman Empire, may linger on long after its death. (Full article...)
Image 4Gray goo (also spelled as grey goo) is a hypothetical global catastrophic scenario involving molecular nanotechnology in which out-of-control self-replicating machines consume all biomass (and perhaps also everything else) on Earth while building many more of themselves, a scenario that has been called ecophagy (the literal consumption of the ecosystem). The original idea assumed machines were designed to have this capability, while popularizations have assumed that machines might somehow gain this capability by accident.
Self-replicating machines of the macroscopic variety were originally described by mathematician John von Neumann, and are sometimes referred to as von Neumann machines or clanking replicators. The term gray goo was coined by nanotechnology pioneer K. Eric Drexler in his 1986 book Engines of Creation. In 2004, he stated "I wish I had never used the term 'gray goo'." Engines of Creation mentions "gray goo" as a thought experiment in two paragraphs and a note, while the popularized idea of gray goo was first publicized in a mass-circulation magazine, Omni, in November 1986.

Image 5Ocean acidification means that the average seawaterpH value is dropping over time.
Ocean acidification is the ongoing decrease in the pH of the Earth's ocean. Between 1950 and 2020, the average pH of the ocean surface fell from approximately 8.15 to 8.05. Carbon dioxide emissions from human activities are the primary cause of ocean acidification, with atmospheric carbon dioxide (CO2) levels exceeding 422 ppm (as of 2024). CO2 from the atmosphere is absorbed by the oceans. This chemical reaction produces carbonic acid (H2CO3) which dissociates into a bicarbonate ion (HCO−3) and a hydrogen ion (H). The presence of free hydrogen ions (H) lowers the pH of the ocean, increasing acidity (this does not mean that seawater is acidic yet; it is still alkaline, with a pH higher than 8). Marine calcifying organisms, such as mollusks and corals, are especially vulnerable because they rely on calcium carbonate to build shells and skeletons.
A change in pH by 0.1 represents a 26% increase in hydrogen ion concentration in the world's oceans (the pH scale is logarithmic, so a change of one in pH units is equivalent to a tenfold change in hydrogen ion concentration). Sea-surface pH and carbonate saturation states vary depending on ocean depth and location. Colder and higher latitude waters are capable of absorbing more CO2. This can cause acidity to rise, lowering the pH and carbonate saturation levels in these areas. There are several other factors that influence the atmosphere-ocean CO2 exchange, and thus local ocean acidification. These include ocean currents and upwelling zones, proximity to large continental rivers, sea ice coverage, and atmospheric exchange with nitrogen and sulfur from fossil fuel burning and agriculture.
A lower ocean pH has a range of potentially harmful effects for marine organisms. Scientists have observed for example reduced calcification, lowered immune responses, and reduced energy for basic functions such as reproduction. Ocean acidification can impact marine ecosystems that provide food and livelihoods for many people. About one billion people are wholly or partially dependent on the fishing, tourism, and coastal management services provided by coral reefs. Ongoing acidification of the oceans may therefore threaten food chains linked with the oceans. (Full article...)
Image 6Pollution is the introduction of contaminants into the natural environment that cause harm. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
Image 7Human overpopulation (or human population overshoot) is the idea that human populations may become too large to be sustained by their environment or resources in the long term. The topic is usually discussed in the context of world population, though it may concern individual nations, regions, and cities.
Since 1804, the global living human population has increased from 1 billion to 8 billion due to medical advancements and improved agricultural productivity. Annual world population growth peaked at 2.1% in 1968 and has since dropped to 1.1%. According to the most recent United Nations' projections, the global human population is expected to reach 9.7 billion in 2050 and would peak at around 10.4 billion people in the 2080s, before decreasing, noting that fertility rates are falling worldwide. Other models agree that the population will stabilize before or after 2100. Conversely, other researchers have found that national birth registries data from 2022 and 2023 that cover half the world's population indicate that the 2022 UN projections overestimated fertility rates by 10 to 20% and are already outdated, that the global fertility rate has possibly already fallen below the sub-replacement fertility level for the first time in human history, and that the global population will peak at approximately 9.5 billion by 2061. The 2024 UN projections report estimated that world population would peak at 10.29 billion in 2084 and decline to 10.18 billion by 2100, which was 6% lower than the UN had estimated in 2014.
Image 8The dodo became extinct during the mid-to-late 17th century due to habitat destruction, overhunting, and predation by introduced mammals. It is an often-cited example of a human-driven extinction.
The Holocene extinction, also referred to as the Anthropocene extinction, is an ongoing extinction event caused by human activities during the Holocene epoch. This extinction event spans numerous families of plants and animals, including mammals, birds, reptiles, amphibians, fish, and invertebrates, impacting both terrestrial and marine species. Widespread degradation of biodiversity hotspots such as coral reefs and rainforests has exacerbated the crisis. Many of these extinctions are undocumented, as the species are often undiscovered before their extinctions.
Current extinction rates are estimated at 100 to 1,000 times higher than natural background extinction rates and are accelerating. Over the past 100–200 years, biodiversity loss has reached such alarming levels that some conservation biologists now believe human activities have triggered a mass extinction, or are on the cusp of doing so. As such, after the "Big Five" mass extinctions, the Holocene extinction event has been referred to as the sixth mass extinction. However, given the recent recognition of the Capitanian mass extinction, the term seventh mass extinction has also been proposed.
The Holocene extinction was preceded by the extinction of most large (megafaunal) animals during the Late Pleistocene, a decline attributed in part to human hunting. The prevailing theory is that human overhunting, coinciding with existing stress conditions, likely contributed to this decline. Examples from regions such as New Zealand, Madagascar, and Hawaii have shown how human colonization and habitat destruction have led to significant biodiversity losses. While debates persist about the exact role of human predation and habitat alteration, certain extinctions have been directly linked to these activities. Additionally, climate shifts at the end of the Pleistocene likely compounded these effects. (Full article...)
Image 9Summary of major environmental-change categories that cause biodiversity loss. The data is expressed as a percentage of human-driven change (in red) relative to baseline (blue), as of 2021. Red indicates the percentage of the category that is damaged, lost, or otherwise affected, whereas blue indicates the percentage that is intact, remaining, or otherwise unaffected. Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far. These activities include habitat destruction (for example deforestation) and land use intensification (for example monoculture farming). Further problem areas are air and water pollution (including nutrient pollution), over-exploitation, invasive species and climate change.
Climate change is another threat to global biodiversity. For example, coral reefs—which are biodiversity hotspots—will be lost by the year 2100 if global warming continues at the current rate. Still, it is the general habitat destruction (often for expansion of agriculture), not climate change, that is currently the bigger driver of biodiversity loss. Invasive species and other disturbances have become more common in forests in the last several decades. These tend to be directly or indirectly connected to climate change and can cause a deterioration of forest ecosystems. (Full article...)
Image 10Solid waste after being shredded to a uniform size Waste (or wastes) are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero.
While the ability to deliberately engineer pathogens has been constrained to high-end labs run by top researchers, the technology to achieve this is rapidly becoming cheaper and more widespread. For example, the diminishing cost of sequencing the human genome (from $10 million to $1,000), the accumulation of large datasets of genetic information, the discovery of gene drives, and the discovery of CRISPR. Biotechnology risk is therefore a credible explanation for the Fermi paradox. (Full article...)

Environmental disasters show how the impact of humans' alteration of the land has led to widespread and/or long-lasting consequences. These disasters have included deaths of wildlife, humans and plants, or severe disruption of human life or health, possibly requiring migration. Some environmental disasters are the trigger source of more expansive environmental conflicts, where effected groups try to socially confront the actors responsible for the disaster.

Image 15The distribution of atmospheric ozone in partial pressure as a function of altitude Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and a much larger springtime decrease in stratospheric ozone (the ozone layer) around Earth's polar regions. The latter phenomenon is referred to as the ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events.
The main causes of ozone depletion and the ozone hole are manufactured chemicals, especially manufactured halocarbonrefrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS). These compounds are transported into the stratosphere by turbulent mixing after being emitted from the surface, mixing much faster than the molecules can settle. Once in the stratosphere, they release atoms from the halogen group through photodissociation, which catalyze the breakdown of ozone (O3) into oxygen (O2). Both types of ozone depletion were observed to increase as emissions of halocarbons increased.
Ozone depletion and the ozone hole have generated worldwide concern over increased cancer risks and other negative effects. The ozone layer prevents harmful wavelengths of ultraviolet (UVB) light from passing through the Earth's atmosphere. These wavelengths cause skin cancer, sunburn, permanent blindness, and cataracts, which were projected to increase dramatically as a result of thinning ozone, as well as harming plants and animals. These concerns led to the adoption of the Montreal Protocol in 1987, which bans the production of CFCs, halons, and other ozone-depleting chemicals. Over time, scientists have developed new refrigerants with lower global warming potential (GWP) to replace older ones. For example, in new automobiles, R-1234yf systems are now common, being chosen over refrigerants with much higher GWP such as R-134a and R-12. (Full article...)
The prerequisites for the crisis were complex. During the 1990s, the U.S. Congress had passed legislation intended to expand affordable housing through looser financing. In 1999, parts of the Glass–Steagall legislation (passed in 1933) were repealed, permitting institutions to mix low-risk operations, such as commercial banking and insurance, with higher-risk operations such as investment banking and proprietary trading. As the Federal Reserve ("Fed") lowered the federal funds rate from 2000 to 2003, institutions increasingly targeted low-income homebuyers, largely belonging to racial minorities, with high-risk loans; this development went unattended by regulators. As interest rates rose from 2004 to 2006, the cost of mortgages rose and the demand for housing fell, causing property values to decline. In early 2007, as more U.S. mortgage holders began defaulting on their repayments, subprime lenders went bankrupt, culminating in April with the bankruptcy of New Century Financial. As demand and prices continued to fall, the contagion spread to worldwide credit markets by August, and central banks began injecting liquidity. By July 2008, Fannie Mae and Freddie Mac, companies which together owned or guaranteed half of the U.S. housing market, were on the verge of collapse; the Housing and Economic Recovery Act enabled the government to take over and cover their combined $1.6 trillion debt on September 7.
Access to health care may vary across countries, communities, and individuals, influenced by social and economic conditions and health policies. Providing health care services means "the timely use of personal health services to achieve the best possible health outcomes". Factors to consider in terms of health care access include financial limitations (such as insurance coverage), geographical and logistical barriers (such as additional transportation costs and the ability to take paid time off work to use such services), sociocultural expectations, and personal limitations (lack of ability to communicate with health care providers, poor health literacy, low income). Limitations to health care services affect negatively the use of medical services, the efficacy of treatments, and overall outcome (well-being, mortality rates).
Health systems are the organizations established to meet the health needs of targeted populations. According to the World Health Organization (WHO), a well-functioning health care system requires a financing mechanism, a well-trained and adequately paid workforce, reliable information on which to base decisions and policies, and well-maintained health facilities to deliver quality medicines and technologies.

Image 18A typical suburban development in the United States, located in Chandler, Arizona Urban sprawl (also known as suburban sprawl or urban encroachment) is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a city". Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for very dense urban planning. Sometimes the urban areas described as the most "sprawling" are the most densely populated. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. In modern times some suburban areas described as "sprawl" have less detached housing and higher density than the nearby core city. Medieval suburbs suffered from the loss of protection of city walls, before the advent of industrial warfare. Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The revenue for building and maintaining urban infrastructure in these areas are gained mostly through property and sales taxes. Most jobs in the US are now located in suburbs generating much of the revenue, although a lack of growth will require higher tax rates.
In Europe, the term peri-urbanisation is often used to denote similar dynamics and phenomena, but the term urban sprawl is currently being used by the European Environment Agency. There is widespread disagreement about what constitutes sprawl and how to quantify it. For example, some commentators measure sprawl by residential density, using the average number of residential units per acre in a given area. Others associate it with decentralization (spread of population without a well-defined centre), discontinuity (leapfrogging development, as defined below), segregation of uses, and so forth.
The term urban sprawl is highly politicized and almost always has negative connotations. It is criticized for causing environmental degradation, intensifying segregation, and undermining the vitality of existing urban areas, and is attacked on aesthetic grounds. The pejorative meaning of the term means that few openly support urban sprawl as such. The term has become a rallying cry for managing urban growth. (Full article...)
One argument for the importance of this risk references how human beings dominate other species because the human brain possesses distinctive capabilities other animals lack. If AI were to surpass human intelligence and become superintelligent, it might become uncontrollable. Just as the fate of the mountain gorilla depends on human goodwill, the fate of humanity could depend on the actions of a future machine superintelligence.
The plausibility of existential catastrophe due to AI is widely debated. It hinges in part on whether AGI or superintelligence are achievable, the speed at which dangerous capabilities and behaviors emerge, and whether practical scenarios for AI takeovers exist. Concerns about superintelligence have been voiced by computer scientists and tech CEOs such as Geoffrey Hinton, Yoshua Bengio, Alan Turing, Elon Musk, and OpenAI CEO Sam Altman. In 2022, a survey of AI researchers with a 17% response rate found that the majority believed there is a 10 percent or greater chance that human inability to control AI will cause an existential catastrophe. In 2023, hundreds of AI experts and other notable figures signed a statement declaring, "Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war". Following increased concern over AI risks, government leaders such as United Kingdom prime ministerRishi Sunak and United Nations Secretary-GeneralAntónio Guterres called for an increased focus on global AI regulation.

The origins of the Internet date back to research that enabled the time-sharing of computer resources, the development of packet switching in the 1960s and the design of computer networks for data communication. The set of rules (communication protocols) to enable internetworking on the Internet arose from research and development commissioned in the 1970s by the Defense Advanced Research Projects Agency (DARPA) of the United States Department of Defense in collaboration with universities and researchers across the United States and in the United Kingdom and France. The ARPANET initially served as a backbone for the interconnection of regional academic and military networks in the United States to enable resource sharing. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, encouraged worldwide participation in the development of new networking technologies and the merger of many networks using DARPA's Internet protocol suite. The linking of commercial networks and enterprises by the early 1990s, as well as the advent of the World Wide Web, marked the beginning of the transition to the modern Internet, and generated sustained exponential growth as generations of institutional, personal, and mobilecomputers were connected to the internetwork. Although the Internet was widely used by academia in the 1980s, the subsequent commercialization of the Internet in the 1990s and beyond incorporated its services and technologies into virtually every aspect of modern life.
Unemployment, according to the OECD (Organisation for Economic Co-operation and Development), is the proportion of people above a specified age (usually 15) not being in paid employment or self-employment but currently available for work during the reference period.
Unemployment is measured by the unemployment rate, which is the number of people who are unemployed as a percentage of the labour force (the total number of people employed added to those unemployed).
Unemployment can have many sources, such as the following: (Full article...)
Image 23Deforestation of the Amazon rainforest in Brazil's Maranhão state, 2016 Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage.
Image 24Global distribution of dryland areas based on the aridity index computed over a 30-year average during 1981 to 2010. Typical deserts are indicated by the hyper-arid category (light yellow). Desertification is a type of gradual land degradation of fertile land into arid desert due to a combination of natural processes and human activities.
The immediate cause of desertification is the loss of most vegetation. This is driven by a number of factors, alone or in combination, such as drought, climatic shifts, tillage for agriculture, overgrazing and deforestation for fuel or construction materials. Though vegetation plays a major role in determining the biological composition of the soil, studies have shown that, in many environments, the rate of erosion and runoff decreases exponentially with increased vegetation cover. Unprotected, dry soil surfaces blow away with the wind or are washed away by flash floods, leaving infertile lower soil layers that bake in the sun and become an unproductive hardpan. This spread of arid areas is caused by a variety of factors, such as overexploitation of soil as a result of human activity and the effects of climate change.
At least 90% of the inhabitants of drylands live in developing countries, where they also suffer from poor economic and social conditions. This situation is exacerbated by land degradation because of the reduction in productivity, the precariousness of living conditions and the difficulty of access to resources and opportunities.

Besides the immediate destruction of cities by nuclear blasts, the potential aftermath of a nuclear war could involve firestorms, a nuclear winter, widespread radiation sickness from fallout, and/or the temporary (if not permanent) loss of much modern technology due to electromagnetic pulses. Some scientists, such as Alan Robock, have speculated that a thermonuclear war could result in the end of modern civilization on Earth, in part due to a long-lasting nuclear winter. In one model, the average temperature of Earth following a full thermonuclear war falls for several years by 7 – 8 °C (13 to 15 degrees Fahrenheit) on average.
Early Cold War-era studies suggested that billions of humans would survive the immediate effects of nuclear blasts and radiation following a global thermonuclear war. The International Physicians for the Prevention of Nuclear War believe that nuclear war could indirectly contribute to human extinction via secondary effects, including environmental consequences, societal breakdown, and economic collapse.

Image 1A swan created using modular origami, a paperfolding technique which uses two or more sheets of paper to create a larger and more complex structure than possible with single-piece origami techniques. Each individual sheet of paper is folded into a module, or unit, and then modules are assembled into an integrated flat shape or three-dimensional structure by inserting flaps into pockets created by the folding process. These insertions create tension or friction that holds the model together.

Image 3The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Saint Anthony Falls of the Mississippi River in Minneapolis, Minnesota. Once the third-busiest bridge in the state, it suddenly collapsed on August 1, 2007, killing 13 and injuring 145. Rescue of people stranded on the bridge was complete in three hours, while recovery of bodies—involving 75 local, state and federal agencies—took three weeks. An NTSB investigation cited a design flaw as the likely cause of the collapse, noting that a too-thin gusset plate ripped along a line of rivets.

In mid-2014, the images' hosting on Wikimedia Commons was at the centre of a dispute over whether copyright could be held on artworks made by non-human animals. Slater argued that, as he had "engineered" the shot, he held copyright, while Wikimedia considered the photographs public domain on the grounds that they were made by an animal rather than a person. In December 2014, the United States Copyright Office stated that works by a non-human are not subject to US copyright, a view reaffirmed by a US federal judge in 2016.
Image 9The Pinwheel Galaxy is a face-on spiral galaxy located 21 million light-years away in the constellationUrsa Major. It was first discovered by Pierre Méchain on March 27, 1781, and communicated to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries. This image, released on February 28, 2006, is composed of 51 individual exposures, as well as some extra ground-based photos. At the time of its release, it was the largest and most detailed image of a galaxy by the Hubble Space Telescope.
Image 10The American Bison, or Buffalo, is the largest terrestrial mammal in North America, and once inhabited the Great Plains in massive herds. They were central to the lives of Native American tribes. This pile of bison skulls from the 1870s illustrates the extent of their slaughter in the 19th century by settlers: from a population of about 60 million in 1800 to as few as 750 in 1890. They have since been reintroduced into the wild and are no longer considered a high risk endangered species.

Image 13The Aqueduct of Segovia is a Roman aqueduct located in Segovia, Spain that transports water from the Rio Frio. It is thought to have been constructed during the 1st century CE. One of the most significant and best-preserved ancient monuments left on the Iberian Peninsula, the aqueduct is considered a symbol of Segovia and is present on the city's coat of arms.
Image 14The International Space Station (ISS) as seen from the Space Shuttle Endeavour. Zarya, the first module of the ISS launched in 1998, is seen in the foreground. Since then, twenty-six Space Shuttle flights have docked with the ISS to assemble various other modules and components, which include four pairs of solar arrays seen on each side.
Image 20The Leaning Tower of Pisa is the freestanding bell tower of the Cathedral of Pisa, Italy. The third oldest structure in the city's Square of Miracles, it is known worldwide for its unintended tilt. The tower's tilt began during construction in the 12th century, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight. The tilt gradually increased until the tower was stabilized (and the tilt partially corrected) by efforts in the late 20th and early 21st centuries. The tower, which measures 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side, has been listed as a UNESCO World Heritage Site since 1987.
Image 22NGC 1300 is a barred spiral galaxy located roughly 69 million light-years away in the direction of the constellation Eridanus. In its core, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long.
Image 23Crash landing of an F6F Hellcat into the port side 20mm gun gallery of the USS Enterprise, November 10, 1943. Lieutenant Walter L. Chewning, Jr., USNR, the Catapult Officer, is climbing up the plane's side to assist the pilot from the burning aircraft. The pilot, Ensign Byron M. Johnson, escaped without significant injury. Note the plane's ruptured belly fuel tank.
Image 26A neutral density filter is a filter that reduces or modifies the intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition. The filter reduces the amount of light entering the lens, allowing the photographer to select combinations of aperture, exposure time and sensor sensitivity to avoid overexposed pictures. It would normally be attached to the lens, but is hand-held here to illustrate the effect.
Image 30Imagine waking up to this. Which makes me wonder whatever happened to the guy who took this photo.
Image 31A lava lake at Mount Nyiragongo, a volcano found in Virunga National Park in the Democratic Republic of the Congo. Lava lakes, which can form in three different ways, are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. Persistent lava lakes such as the one at Nyiragongo, which is the largest to appear in recent times, are rare.
Image 32A dust storm rushes towards a military camp as it rolls over Al Asad Airbase, Iraq, just before nightfall on April 27, 2005. A dust storm (or sandstorm) is a meteorological phenomenon common in dry, arid and semi-arid regions, usually the result of convection currents created by intense heating of the ground. These currents then carry clouds of sand over large distances.
Image 33Devastation caused by Hurricane Katrina in New Orleans, Louisiana during 2005, shown here looking down on Interstate 10 at West End Boulevard towards Lake Pontchartrain. Over 1,800 people were confirmed dead with 705 still missing. It was the costliest Atlantic hurricane in history causing around $86 billion in damage. This photo shows flooded roadways as the United States Coast Guard conducted initial damage assessment overflights of New Orleans on Monday, August 29, 2005. The city flooded due primarily to the failure of the levee system. Many who remained in their homes had to swim for their lives, wade through deep water, or remain trapped in their attics or on their rooftops.
Image 36The sperm whale is the largest toothed animal on Earth. The species was hunted extensively by humans throughout history, until protected by a worldwide moratorium on whaling starting in 1985–86.
Image 38Glaucus atlanticus is a species of small, blue sea slug. This pelagic aeolid nudibranch floats upside down, using the surface tension of the water to stay up, and is carried along by the winds and ocean currents. The blue side of their body faces upwards, blending in with the blue of the water, while the grey side faces downwards, blending in with the silvery surface of the sea. G. atlanticus feeds on other pelagic creatures, including the Portuguese man o' war.
Image 42San Francisco Bay shrouded in fog, as seen from the Marin Headlands looking east. The fog of San Francisco is a kind of sea fog, created when warm, moist air blows from the central Pacific Ocean across the cold water of the California Current, which flows just off the coast. The water is cold enough to lower the temperature of the air to the dew point, causing fog generation. In this photo, the towers of the Golden Gate Bridge can be seen poking through the fog, and the Bay Bridge is visible in the distance.

Image 44A man engaging in big wave surfing at Mavericks, located just north of Half Moon Bay, California. Big wave surfing is a discipline within surfing in which experienced surfers paddle into or are towed onto waves which are at least 20 ft (6.1 m) high, and is a hazardous activity, as surfers can be pushed far beneath the surface of the water after a wipeout.
Image 45An animation of a cicada undergoing ecdysis, the molting of the exoskeleton in arthropods and related groups. Since the cuticula of these animals is inelastic, it is shed during growth and a new, larger covering is formed. The old, empty exoskeleton is called an exuvia. Within one or two hours, the cuticle hardens and darkens, during which time the animal grows, since growth is otherwise constrained by the rigidity of the exoskeleton. Each frame of this image was taken at one-minute intervals, with a 30-minute gap in middle while the cicada rested. The entire process took about 2 hours to complete.

A valuable service
I think you need recognition for doing the job of ten other editors, and doing it out of altruism and genuine belief in Misplaced Pages. Not many editors here have the same good attitude and provide the same service as you - I don't have any specific point to put across, but I thought you should just be prodded and reminded that you do a lot of good around here, in the hope you'll keep it up. Kudos! Seegoon (talk) 17:43, 25 January 2008 (UTC)
Just a note, I've made a minor update to your contributions. To reiterate my edit summary, you put in a tonne of effort there, and you deserve to be credited for it :) Feel free to revert, nonetheless. Regards, AGK (contact) 16:44, 29 February 2008 (UTC)

Over the years it has grown, but I don't know if I ever would have started it without seeing your menus first. I just want to thank you for putting the effort into creating those menus and then sharing them at the Design Center where they have been helpful for people like me.

please help translate this message into the local language
In 2015 you were one of the top 300 medical editors across any language of Misplaced Pages. Thank you from Wiki Project Med Foundation for helping bring free, complete, accurate, up-to-date health information to the public. We really appreciate you and the vital work you do! Wiki Project Med Foundation is a user group whose mission is to improve our health content. Consider joining here, there are no associated costs, and we would love to collaborate further.
Hi there! I just wanted to let you know that I think your planet outlines are really cool. I have long thought it was a shame that only Wikipedians seem to know about Books or Portals, because they are really great tools for structuring knowledge (while everyone loves diving down the Misplaced Pages rabbit hole, we could really do with some better content organization). The outlines strike me as a great way to bring that sort content organization to mainspace, where it will actually reach a large number of readers. I notice that I am the first one to edit them besides yourself, and I hope you know that I do so with love.
What a Brilliant Idea Barnstar
Great idea with the outline articles - a great solution to a need for better mainspace-based content structuring! I see from WP:Outlines that you actually came up with this concept some years ago, but this is the first I've noticed it. A2soup (talk) 02:46, 8 February 2017 (UTC)

The Portal Barnstar
The Portal Barnstar is awarded to Wikipedians who have made significant contributions to topic portals. Awarded to Transhumanist for his overly enthusiastic efforts regarding the portal system and WikiProject Portals. – Lionel 11:02, 30 April 2018 (UTC)
Transhumanist, thank you for your extraordinary efforts on behalf of portals. It reminds me of the time when a series of attacks on scientific bibliographies led to the formation of WikiProject Bibliographies. I don't understand why your detractors are so passionate about deleting portals, but your actions have been a model for how to deal with an attack constructively. RockMagnetist(talk) 16:10, 5 May 2018 (UTC)

The Article Rescue Barnstar
May all who see this barnstar know that The Transhumanist made a valiant and commendable effort for defending the portal namespace from deletion. It preserved countless hours of work initially invested into creating the content. Moreoever, The Transhumanist, is doing a yeoman's job in attempting to improve the content within with portal namespace. RightCowLeftCoast (talk) 00:24, 26 May 2018 (UTC)
@RightCowLeftCoast: Thank you. I feel honored. Please keep in mind that I have not been working alone. Credit goes to the nearly 400 editors who came forward to speak up for the keeping of portals. And although the RfC to delete all portals is over, the job of defending portals from deletion is not. For the portal namespace to be retained in the long term, the portals in it will need to be improved to a worthy quality level, otherwise we may see more deletion attempts. This task is far more than a single editor can handle. Fortunately, many editors have come forward to meet the challenge. Working to develop portals and the entire portal system, is a team of 80 editors who are diligently redesigning, upgrading, updating, and maintaining portals. They are the members of the Portals WikiProject, and without them there might be no portals. They are doing a wonderful job, and I am very proud of them. Thank you. — The Transhumanist 17:22, 26 May 2018 (UTC)
Thank you for your thoughts and efforts regarding portals, for the concept of outlines, for sectional redirects, for articles such as Life Extension Foundation, for service from 2006, including portal philosophy and user page design center, - repeating (1 & 4 June 2009): you are an awesome Wikipedian!

Image 1A swan created using modular origami, a paperfolding technique which uses two or more sheets of paper to create a larger and more complex structure than possible with single-piece origami techniques. Each individual sheet of paper is folded into a module, or unit, and then modules are assembled into an integrated flat shape or three-dimensional structure by inserting flaps into pockets created by the folding process. These insertions create tension or friction that holds the model together.
Image 2An overhead view of Skylab, the United States' first space station, in Earth orbit as photographed from the Skylab 4 Command and Service Modules. Skylab 4 was the last mission to Skylab and brought back its final crew; this photograph was the last one taken of the station before the mission re-entered Earth's atmosphere and disintegrated in 1979.
Image 3The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Saint Anthony Falls of the Mississippi River in Minneapolis, Minnesota. Once the third-busiest bridge in the state, it suddenly collapsed on August 1, 2007, killing 13 and injuring 145. Rescue of people stranded on the bridge was complete in three hours, while recovery of bodies—involving 75 local, state and federal agencies—took three weeks. An NTSB investigation cited a design flaw as the likely cause of the collapse, noting that a too-thin gusset plate ripped along a line of rivets.
Image 4The Door to Hell is a natural gas field in Derweze, Turkmenistan, which has been burning since 1971 when it was ignited by Soviet scientists who expected it to burn out within days. They were trying to prevent the release of poisonous gases. The name "Door to Hell" was given to the field by locals. The hot spots range over an area with a width of 60 metres (200 ft) and to a depth of about 20 metres (66 ft).
Image 5The Hubble Extreme Deep Field is an image of a small area of space in the constellation Fornax released by NASA on September 25, 2012. The successor to the Hubble Ultra-Deep Field, this image was compiled from 10 years of previous images with a total exposure time of two million seconds, or approximately 23 days.
Image 6Lucky Diamond Rich (b. 1971) is a New Zealand-born performance artist and street performer who holds the Guinness World Record for most tattooed man, taking the title from Tom Leppard in 2006. He is recognized by Guinness as being covered in tattoos over 100% of his body, including the inside of his eyelids, ears, and mouth.
Image 7aurora australis, as seen from the International Space Station. Aurorae are natural light displays in the sky caused by the collision of energetic charged particles with atoms in the high altitude thermosphere. The particles originate in the magnetosphere and solar wind and, on Earth, are directed by Earth's magnetic field into the atmosphere.
Image 8One of two monkey selfies taken by Celebes crested macaques using equipment belonging to the British nature photographer David Slater. In mid-2014, the images' hosting on Wikimedia Commons was at the centre of a dispute over whether copyright could be held on artworks made by non-human animals. Slater argued that, as he had "engineered" the shot, he held copyright, while Wikimedia considered the photographs public domain on the grounds that they were made by an animal rather than a person. In December 2014, the United States Copyright Office stated that works by a non-human are not subject to US copyright, a view reaffirmed by a US federal judge in 2016.
Image 9The Pinwheel Galaxy is a face-on spiral galaxy located 21 million light-years away in the constellation Ursa Major. It was first discovered by Pierre Méchain on March 27, 1781, and communicated to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries. This image, released on February 28, 2006, is composed of 51 individual exposures, as well as some extra ground-based photos. At the time of its release, it was the largest and most detailed image of a galaxy by the Hubble Space Telescope.
Image 10The American Bison, or Buffalo, is the largest terrestrial mammal in North America, and once inhabited the Great Plains in massive herds. They were central to the lives of Native American tribes. This pile of bison skulls from the 1870s illustrates the extent of their slaughter in the 19th century by settlers: from a population of about 60 million in 1800 to as few as 750 in 1890. They have since been reintroduced into the wild and are no longer considered a high risk endangered species.
Image 11Sandboarding is a boardsport similar to snowboarding, but competitions take place on sand dunes rather than snow-covered mountains. Here, a member of the US Navy sandboards down a dune in Jebel Ali, Dubai.

Image 13The Aqueduct of Segovia is a Roman aqueduct located in Segovia, Spain that transports water from the Rio Frio. It is thought to have been constructed during the 1st century CE. One of the most significant and best-preserved ancient monuments left on the Iberian Peninsula, the aqueduct is considered a symbol of Segovia and is present on the city's coat of arms.
Image 14The International Space Station (ISS) as seen from the Space Shuttle Endeavour. Zarya, the first module of the ISS launched in 1998, is seen in the foreground. Since then, twenty-six Space Shuttle flights have docked with the ISS to assemble various other modules and components, which include four pairs of solar arrays seen on each side.
Image 15Atlantic White-sided Dolphins, on a concrete-floored dock at the port of Hvalba, which is in the Faroe Islands, north of the United Kingdom. Whaling in the Faroe Islands has been practised since at least the 10th century. It is strongly regulated by Faroese authorities and is approved by the International Whaling Commission.
Image 16United States Navy personnel engage in Special Patrol Insertion/Extraction (SPIE) training between a Sikorsky SH-60 Seahawk helicopter and the USS Dwight D. Eisenhower (CVN-69). SPIE involves either a person or goods being lowered from or raised to a helicopter via a cable above terrain on which landing would be difficult.

Image 18The "Baker" explosion, part of Operation Crossroads, a nuclear weapon test by the United States military at Bikini Atoll, Micronesia, on July 25, 1946. Its purpose was to test the effect of nuclear weapons on naval ships. It was the second US nuclear bomb set off since the bombing of Nagasaki.
Image 19Burj Khalifa is a skyscraper in Dubai, United Arab Emirates, and currently the tallest man-made structure in the world, at 829.8 m (2,722 ft). It was designed to be the centerpiece of a large-scale, mixed-use development known as Downtown Dubai. Construction took over five years, and the skyscraper was officially opened in January 2010.
Image 20The Leaning Tower of Pisa is the freestanding bell tower of the Cathedral of Pisa, Italy. The third oldest structure in the city's Square of Miracles, it is known worldwide for its unintended tilt. The tower's tilt began during construction in the 12th century, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight. The tilt gradually increased until the tower was stabilized (and the tilt partially corrected) by efforts in the late 20th and early 21st centuries. The tower, which measures 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side, has been listed as a UNESCO World Heritage Site since 1987.
Image 21The mushroom cloud from the Ivy Mike nuclear test, one of two tests conducted as part of Operation Ivy at the Pacific Proving Grounds on Elugelab in the Marshall Islands. Mike was the first successful full-scale test of a multi-megaton thermonuclear weapon, and it left an underwater crater 6,240 ft (1,900 m) wide and 164 ft (50 m) deep where the island had been.
Image 22NGC 1300 is a barred spiral galaxy located roughly 69 million light-years away in the direction of the constellation Eridanus. In its core, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long.
Image 23Crash landing of an F6F Hellcat into the port side 20mm gun gallery of the USS Enterprise, November 10, 1943. Lieutenant Walter L. Chewning, Jr., USNR, the Catapult Officer, is climbing up the plane's side to assist the pilot from the burning aircraft. The pilot, Ensign Byron M. Johnson, escaped without significant injury. Note the plane's ruptured belly fuel tank.

Image 25Crowds surrounding the Reflecting Pool, during the August 28 1963 March on Washington for Jobs and Freedom. An estimated 200,000 to 500,000 people participated in the march, which featured Martin Luther King Jr.'s famous "I Have a Dream" speech. It was a major factor leading to the passage of the Civil Rights Act of 1964 and the 1965 Voting Rights Act. The march was also condemned by the Nation of Islam and Malcolm X, who termed it the "farce on Washington".
Image 26A neutral density filter is a filter that reduces or modifies the intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition. The filter reduces the amount of light entering the lens, allowing the photographer to select combinations of aperture, exposure time and sensor sensitivity to avoid overexposed pictures. It would normally be attached to the lens, but is hand-held here to illustrate the effect.
Image 27Tracy Caldwell Dyson in the Cupola module of the International Space Station, observing the Earth below during Expedition 24. Caldwell Dyson is an American chemist and astronaut. She was selected by NASA in 1998 and made her first spaceflight in August 2007 on the STS-118 mission aboard Space Shuttle Endeavour.
Image 28American astronaut Eugene Cernan (born March 14, 1934), shown here on the surface of the Moon during the Apollo 17 mission, the last time any human has set foot on it. In that final lunar landing mission, launched December 7, 1972, Cernan became "the last man on the moon" since he was the last to re-enter the Apollo Lunar Module during its third and final extra-vehicular activity. Prior to this, Cernan had also gone into space twice on the Gemini 9A and Apollo 10 missions.
Image 29The mushroom cloud caused by the detonation of the "Fat Man" bomb during the atomic bombing of Nagasaki, Japan in 1945, rising approximately 18 kilometres (11 mi) above the hypocenter.
Image 30Imagine waking up to this. Which makes me wonder whatever happened to the guy who took this photo.
Image 31A lava lake at Mount Nyiragongo, a volcano found in Virunga National Park in the Democratic Republic of the Congo. Lava lakes, which can form in three different ways, are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. Persistent lava lakes such as the one at Nyiragongo, which is the largest to appear in recent times, are rare.
Image 32A dust storm rushes towards a military camp as it rolls over Al Asad Airbase, Iraq, just before nightfall on April 27, 2005. A dust storm (or sandstorm) is a meteorological phenomenon common in dry, arid and semi-arid regions, usually the result of convection currents created by intense heating of the ground. These currents then carry clouds of sand over large distances.
Image 33Devastation caused by Hurricane Katrina in New Orleans, Louisiana during 2005, shown here looking down on Interstate 10 at West End Boulevard towards Lake Pontchartrain. Over 1,800 people were confirmed dead with 705 still missing. It was the costliest Atlantic hurricane in history causing around $86 billion in damage. This photo shows flooded roadways as the United States Coast Guard conducted initial damage assessment overflights of New Orleans on Monday, August 29, 2005. The city flooded due primarily to the failure of the levee system. Many who remained in their homes had to swim for their lives, wade through deep water, or remain trapped in their attics or on their rooftops.

Image 38Glaucus atlanticus is a species of small, blue sea slug. This pelagic aeolid nudibranch floats upside down, using the surface tension of the water to stay up, and is carried along by the winds and ocean currents. The blue side of their body faces upwards, blending in with the blue of the water, while the grey side faces downwards, blending in with the silvery surface of the sea. G. atlanticus feeds on other pelagic creatures, including the Portuguese man o' war.
Image 39The 2004 Indian Ocean earthquake was a magnitude 9.15, undersea earthquake that occurred at 00:58:53 UTC on December 26 2004. The earthquake generated a tsunami that killed more than 150,000 people around the Indian Ocean, making it one of the deadliest disasters in modern history. This photograph shows the tsunami as it reached Ao Nang, Thailand.

Image 41Astronaut Buzz Aldrin saluting the flag of the United States, part of the Lunar Flag Assembly, during Apollo 11. The Lunar Flag Assembly was designed to survive a Moon landing and to appear to "wave" as it would in a breeze on Earth. This flag fell over when the Lunar Module Eagle took off.
Image 42San Francisco Bay shrouded in fog, as seen from the Marin Headlands looking east. The fog of San Francisco is a kind of sea fog, created when warm, moist air blows from the central Pacific Ocean across the cold water of the California Current, which flows just off the coast. The water is cold enough to lower the temperature of the air to the dew point, causing fog generation. In this photo, the towers of the Golden Gate Bridge can be seen poking through the fog, and the Bay Bridge is visible in the distance.

Image 44A man engaging in big wave surfing at Mavericks, located just north of Half Moon Bay, California. Big wave surfing is a discipline within surfing in which experienced surfers paddle into or are towed onto waves which are at least 20 ft (6.1 m) high, and is a hazardous activity, as surfers can be pushed far beneath the surface of the water after a wipeout.
Image 45An animation of a cicada undergoing ecdysis, the molting of the exoskeleton in arthropods and related groups. Since the cuticula of these animals is inelastic, it is shed during growth and a new, larger covering is formed. The old, empty exoskeleton is called an exuvia. Within one or two hours, the cuticle hardens and darkens, during which time the animal grows, since growth is otherwise constrained by the rigidity of the exoskeleton. Each frame of this image was taken at one-minute intervals, with a 30-minute gap in middle while the cicada rested. The entire process took about 2 hours to complete.
