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 Crowds await news at the Universal Colliery, Senghenydd The Senghenydd colliery disaster, also known as the Senghenydd explosion (Welsh: Tanchwa Senghennydd), occurred at the Universal Colliery in Senghenydd, near Caerphilly, Glamorgan, Wales, on 14 October 1913. The explosion, which killed 439 miners and a rescuer, is the worst mining accident in the United Kingdom. Universal Colliery, on the South Wales Coalfield, extracted steam coal, which was much in demand. Some of the region's coal seams contained high quantities of firedamp, a highly explosive gas consisting of methane and hydrogen. (Full article...)

  • Image 2 Suillellus luridus (formerly Boletus luridus), commonly known as the lurid bolete, is a fungus of the family Boletaceae, found in calcareous broadleaved woodlands in Europe. Fruit bodies appear in summer and autumn and may be locally abundant. It is a firm bolete with an olive-brown cap up to 20 cm (8 in) in diameter, with small orange or red pores on the underside (yellow when young). The stout ochre stem reaches 8–14 cm (3–6 in) high and 1–3 cm (0.4–1.2 in) wide, and is patterned with a red network. Like several other red-pored boletes, it stains blue when bruised or cut.

  • Image 3 The Siberian accentor (Prunella montanella) is a small passerine bird that breeds in northern Russia from the Ural Mountains eastwards across Siberia. It is migratory, wintering in Korea and eastern China, with rare occurrences in western Europe and northwestern North America. Its typical breeding habitat is subarctic deciduous forests and open coniferous woodland, often close to water, although it also occurs in mountains and spruce taiga. It inhabits bushes and shrubs in winter, frequently near streams, but may also be found in dry grassland and woods. (Full article...)

  • Image 4 Lesser horseshoe bat (Rhinolophus hipposideros) with blue metallic identification band on left wing Horseshoe bats are bats in the family Rhinolophidae. In addition to the single living genus, Rhinolophus, which has about 106 species, the extinct genus Palaeonycteris has been recognized. Horseshoe bats are closely related to the Old World leaf-nosed bats, family Hipposideridae, which have sometimes been included in Rhinolophidae. The horseshoe bats are divided into six subgenera and many species groups. The most recent common ancestor of all horseshoe bats lived 34–40 million years ago, though it is unclear where the geographic roots of the family are, and attempts to determine its biogeography have been indecisive. Their taxonomy is complex, as genetic evidence shows the likely existence of many cryptic species, as well as species recognized as distinct that may have little genetic divergence from previously recognized taxa. They are found in the Old World, mostly in tropical or subtropical areas, including Africa, Asia, Europe, and Oceania. (Full article...)

  • Image 5 The yellow-faced honeyeater (Caligavis chrysops) is a small to medium-sized bird in the honeyeater family, Meliphagidae. It takes its common and scientific names from the distinctive yellow stripes on the sides of its head. Its loud, clear call often begins twenty or thirty minutes before dawn. It is widespread across eastern and southeastern Australia, in open sclerophyll forests from coastal dunes to high-altitude subalpine areas, and woodlands along creeks and rivers. Comparatively short-billed for a honeyeater, it is thought to have adapted to a diet of flies, spiders, and beetles, as well as nectar and pollen from the flowers of plants, such as Banksia and Grevillea, and soft fruits. It catches insects in flight as well as gleaning them from the foliage of trees and shrubs. (Full article...)

  • Image 8 Capella is the brightest star in the northern constellation of Auriga. It has the Bayer designation α Aurigae, which is Latinised to Alpha Aurigae and abbreviated Alpha Aur or α Aur. Capella is the sixth-brightest star in the night sky, and the third-brightest in the northern celestial hemisphere after Arcturus and Vega. A prominent object in the northern winter sky, it is circumpolar to observers north of 44°N. Its name meaning "little goat" in Latin, Capella depicted the goat Amalthea that suckled Zeus in classical mythology. Capella is relatively close, at 42.9 light-years (13.2 pc) from the Sun. It is one of the brightest X-ray sources in the sky, thought to come primarily from the corona of Capella Aa. (Full article...)

  • Image 10 Barkhale Camp is a Neolithic causewayed enclosure, an archaeological site on Bignor Hill, on the South Downs in West Sussex, England. Causewayed enclosures were built in England from shortly before 3700 BC until at least 3500 BC; they are characterized by the full or partial enclosure of an area with ditches that are interrupted by gaps, or causeways. Their purpose is not known; they may have been settlements, meeting places, or ritual sites. The Barkhale Camp enclosure was first identified in 1929, by John Ryle, and was surveyed the following year by E. Cecil Curwen, who listed it as a possible Neolithic site in a 1930 paper which was the first attempt to list all the causewayed enclosures in England. (Full article...)

  • Image 12 Resurrectionists (1847), by Hablot Knight Browne. This illustration accompanies an account of John Holmes and Peter Williams who, for unearthing cadavers in 1777, were publicly whipped from Holborn to St Giles. Resurrectionists were body snatchers who were commonly employed by anatomists in the United Kingdom during the 18th and 19th centuries to exhume the bodies of the recently dead. Between 1506 and 1752 only a very few cadavers were available each year for anatomical research. The supply was increased when, in an attempt to intensify the deterrent effect of the death penalty, Parliament passed the Murder Act 1752. By allowing judges to substitute the public display of executed criminals with dissection (a fate generally viewed with horror), the new law significantly increased the number of bodies anatomists could legally access. This proved insufficient to meet the needs of the hospitals and teaching centres that opened during the 18th century. Corpses and their component parts became a commodity, but although the practice of disinterment was hated by the general public, bodies were not legally anyone's property. The resurrectionists therefore operated in a legal grey area. (Full article...)

  • Image 14 Skeletal diagram showing the preserved remains of the holotype specimen Limusaurus is a genus of theropod dinosaur that lived in what is now China during the Late Jurassic, around 161 to 157 million years ago. The type and only species Limusaurus inextricabilis was described in 2009 from specimens found in the Upper Shishugou Formation in the Junggar Basin of China. The genus name consists of the Latin words for "mud" and "lizard", and the species name means "impossible to extricate", both referring to these specimens possibly dying after being mired. Limusaurus was a small, slender animal, about 1.7 m (5 ft 7 in) in length and 15 kg (33 lb) in weight, which had a long neck and legs but very small forelimbs (with reduced first and fourth fingers). It underwent a drastic morphological transformation as it aged: while juveniles were toothed, these teeth were completely lost and replaced by a beak with age. Several of these features were convergently similar to the later ornithomimid theropods as well as the earlier non-dinosaurian shuvosaurids. (Full article...)

Time is the continuous progression of existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions. Scientists have theorized a beginning of time in the universe (the Big Bang) and an end (e.g., heat death or the Big Crunch). A cyclic model describes a cyclical nature, whereas the philosophy of eternalism views the subject from a different angle. (Full article...)
