Members of the Academy in 1667 with Louis XIV

Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into two or three major branches: the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the behavioural sciences (e.g., economics, psychology, and sociology), which study individuals and societies. The formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems governed by axioms and rules, are sometimes described as being sciences as well; however, they are often regarded as a separate field because they rely on deductive reasoning instead of the scientific method or empirical evidence as their main methodology. Applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. (Full article...)

  • Image 1 A North American cougar in Glacier National Park, United States The cougar (Puma concolor) (/ˈkuːɡər/, KOO-gər), also known as the panther, mountain lion, catamount and puma, is a large cat native to the Americas. It inhabits North, Central and South America, making it the most widely distributed wild, terrestrial mammal in the Western Hemisphere, and one of the most widespread in the world. Its range spans the Yukon, British Columbia and Alberta provinces of Canada, the Rocky Mountains and areas in the western United States. Further south, its range extends through Mexico to the Amazon Rainforest and the southern Andes Mountains in Patagonia. It is an adaptable generalist species, occurring in most American habitat types. It prefers habitats with dense underbrush and rocky areas for stalking but also lives in open areas.

  • Image 2 Menstrual cycle The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the uterus (womb) to receive an embryo. These cycles are concurrent and coordinated, normally last between 21 and 35 days, with a median length of 28 days. Menarche (the onset of the first period) usually occurs around the age of 12 years; menstrual cycles continue for about 30–45 years. (Full article...)

  • Image 7 The golden-crowned sifaka or Tattersall's sifaka (Propithecus tattersalli) is a medium-sized lemur characterized by mostly white fur, prominent furry ears, and a golden-orange crown. It is one of the smallest sifakas (genus Propithecus), weighing around 3.5 kg (7.7 lb) and measuring approximately 90 cm (35 in) from head to tail. Like all sifakas, it is a vertical clinger and leaper, and its diet includes mostly seeds and leaves. The golden-crowned sifaka is named after its discoverer, Ian Tattersall, who first spotted the species in 1974. However, it was not formally described until 1988, after a research team led by Elwyn L. Simons observed and captured some specimens for captive breeding. The golden-crowned sifaka most closely resembles the western forest sifakas of the P. verreauxi group, yet its karyotype suggests a closer relationship with the P. diadema group of eastern forest sifakas. Despite the similarities with both groups, more recent studies of its karyotype support its classification as a distinct species. (Full article...)

  • Image 8 Photo by Tee Corinne, 1983 Ann Weldy (born September 15, 1932), better known by her pen name Ann Bannon, is an American author who, from 1957 to 1962, wrote six lesbian pulp fiction novels known as The Beebo Brinker Chronicles. The books' enduring popularity and impact on lesbian identity has earned her the title "Queen of Lesbian Pulp Fiction". Bannon was a young housewife trying to address her own issues of sexuality when she was inspired to write her first novel. Her subsequent books featured four characters who reappeared throughout the series, including her eponymous heroine, Beebo Brinker, who came to embody the archetype of a butch lesbian. The majority of her characters mirrored people she knew, but their stories reflected a life she did not feel she was able to live. Despite her traditional upbringing and role in married life, her novels defied conventions for romance stories and depictions of lesbians by addressing complex homosexual relationships.

  • Image 9 In Buenos Aires The white-rumped swallow (Tachycineta leucorrhoa) is a species of bird in the family Hirundinidae. First described and given its binomial name by French ornithologist Louis Pierre Vieillot in 1817, it was for many years considered a subspecies of the Chilean swallow. The species is monotypic with no known population variations. It has a white supraloral streak, or streak above its lores (the region between a bird's eye and nostrils), which can be used to differentiate it from the Chilean swallow. The lores, ear coverts, tail, and wings are black, with white tips on the inner secondaries, tertials, and greater coverts of the wings. The rest of the upperparts are a glossy blue. Its underparts and underwing-coverts are white, in addition to the rump, as the name suggests. The sexes are similar, and the juvenile is duller and browner with a dusky breast. (Full article...)

  • Image 10 The Temple of Eshmun (Arabic: معبد أشمون) is an ancient place of worship dedicated to Eshmun, the Phoenician god of healing. It is located near the Awali river, 2 kilometres (1.2 mi) northeast of Sidon in southwestern Lebanon. The site was occupied from the 7th century BC to the 8th century AD, suggesting an integrated relationship with the nearby city of Sidon. Although originally constructed by Sidonian king Eshmunazar II in the Achaemenid era (c. 529–333 BC) to celebrate the city's recovered wealth and stature, the temple complex was greatly expanded by Bodashtart, Yatonmilk and later monarchs. Because the continued expansion spanned many centuries of alternating independence and foreign hegemony, the sanctuary features a wealth of different architectural and decorative styles and influences.

  • Image 11 The Old Exe Bridge is a ruined medieval arch bridge in Exeter in south-western England. Construction of the bridge began in 1190, and was completed by 1214. The bridge is the oldest surviving bridge of its size in England and the oldest bridge in Britain with a chapel still on it. It replaced several rudimentary crossings which had been in use sporadically since Roman times. The project was the idea of Nicholas and Walter Gervase, father and son and influential local merchants, who travelled the country to raise funds. No known records survive of the bridge's builders. The result was a bridge at least 590 feet (180 metres) long, which probably had 17 or 18 arches, carrying the road diagonally from the west gate of the city wall across the River Exe and its wide, marshy flood plain.

Although Needham was notorious in London at the time, little is recorded of her life, and no genuine portraits of her survive. Her house was the most exclusive in London and her customers came from the highest strata of fashionable society, but she eventually ran afoul of the moral reformers of the day and died as a result of the severe treatment she received after being sentenced to stand in the pillory.

  • Image 14 El Tatio geyser field El Tatio is a geothermal field with many geysers located in the Andes Mountains of northern Chile at 4,320 metres (14,170 ft) above mean sea level. It is the third-largest geyser field in the world and the largest in the Southern Hemisphere. Various meanings have been proposed for the name "El Tatio", including "oven" or "grandfather". The geothermal field has many geysers, hot springs, and associated sinter deposits. These hot springs eventually form the Rio Salado, a major tributary of the Rio Loa, and are a major source of arsenic pollution in the river. The vents are sites of populations of extremophile microorganisms such as hyperthermophiles, and El Tatio has been studied as an analogue for the early Earth and possible past life on Mars.

    • Some of the lists' items have not yet been integrated into their wikilinked articles; if you add a study there it should also be relevant to at least one other article
    • Maybe this could be done as part of an organized effort
  • Find[how?] studies published under a compatible open license (like CC BY 4.0) and upload the studies' images with descriptions from the study and add these images to articles if they are relevant and useful there
    • When a study with a useful image is published under an incompatible or unclear license (or the image is published not in a study but elsewhere), you could contact its authors (Twitter/Mail) and ask them to give you the permission to upload them under CC BY 4.0 (or whether they could upload the image/s under a compatible license)
    • You can also think about whether images would be useful as you read a science-related article and then search for such images:
      • if they already exist add them (if already on WMCommons) or upload them (if the license is ok) or ask their authors for permissions
      • if they don't, you could create (or request) them
