John Ray: born Nov. 29, 1627, Black Notley, Essex, Eng. died Jan. 17, 1705, Black Notley British naturalist and botanist. He attended Cambridge University and spent many years there as a fellow. With Francis Willughby (1635-1672) he undertook a complete catalog of living things, of which he published numerous volumes. His enduring legacy to botany was the establishment of species as the ultimate unit of taxonomy. He attempted to base his systems of classification on all the structural characteristics of organisms, including internal anatomy, rather than on a single feature. By insisting on the importance of lungs and heart structure, he effectively established the class of mammals, and he divided insects according to the presence or absence of multiple metamorphoses. Coming closer to a truly natural system of taxonomy than had any of his contemporaries, Ray helped make possible Carolus Linnaeus's later contributions

In 1921 he moved to Paris and became associated with the Surrealists. He rediscovered the technique for making "cameraless" pictures (photograms), which he called "rayographs," by placing objects on light-sensitive paper; he also experimented with the technique of solarization, which renders part of the image negative and part positive by exposing a print or negative to a flash of light during development. He turned to portrait and fashion photography and made a virtually complete record of the celebrities of Parisian cultural life of the 1920s and '30s. He also made important contributions as an avant-garde filmmaker in the 1920s

X ray: Electromagnetic radiation of extremely short wavelength (100 nanometres to 0.001 nanometre) produced by the deceleration of charged particles or the transitions of electrons in atoms. X rays travel at the speed of light and exhibit phenomena associated with waves, but experiments indicate that they can also behave like particles (see wave-particle duality). On the electromagnetic spectrum, they lie between gamma rays and ultraviolet radiation. They were discovered in 1895 by Wilhelm Conrad Röntgen, who named them X rays for their unknown nature. They are used in medicine to diagnose bone fractures, dental cavities, and cancer; to locate foreign objects in the body; and to stop the spread of malignant tumours. In industry, they are used to analyze and detect flaws in structures

cosmic ray: A stream of ionizing radiation of extraterrestrial origin, consisting chiefly of protons, alpha particles, and other atomic nuclei but including some high-energy electrons, that enters the atmosphere, collides with atomic nuclei, and produces secondary radiation, principally pions, muons, electrons, and gamma rays. a stream of radiation reaching the Earth from space. High-speed particle (atomic nucleus or electron) that travels through the Milky Way Galaxy. Some cosmic rays originate from the Sun, but most come from outside the solar system. Primary cosmic rays that reach Earth's atmosphere collide with nuclei in it, creating secondaries. Because lower-energy primaries are strongly influenced by the interplanetary magnetic field and Earth's magnetic field (see geomagnetic field), most of those detected near Earth have very high energy, corresponding to speeds about 87% that of light or more. Observations from spacecraft indicate that most cosmic rays come from the Galaxy's disk, but the highest-energy ones are probably extragalactic. Details of their production and acceleration remain unclear, but apparently expanding shock waves from supernovas can accelerate particles. From the early 1930s to the 1950s, cosmic rays were the only source of high-energy particles used in studying the atomic nucleus and its components. Short-lived subatomic particles were discovered through cosmic-ray collisions, leading to the rise of particle physics. Even powerful particle accelerators cannot impart energy anywhere near that of the highest-energy cosmic rays. See also Victor Francis Hess

electric ray: Any of various tropical or subtropical marine fishes of the family Torpedinidae, having a rounded body and a pair of organs capable of producing an electric discharge, which is used to stun or kill prey. Also called crampfish, numbfish, torpedo. Any of the aquatic rays (families Torpedinidae, Narkidae, and Temeridae) that produce an electrical shock. They are found worldwide in warm and temperate seas, mostly in shallow water but some (genus Benthobatis) at depths greater than 3,000 ft (900 m). Slow-moving bottom-dwellers, they feed on fishes and invertebrates. They range in length from less than 1 ft (30 cm) to about 6 ft (1.8 m) and have a short, stout tail. They are soft and smooth-skinned, with a circular or nearly circular body disk formed by the head and pectoral fins. They are harmless unless touched or stepped on. The electric organs, composed of modified muscle tissue, are in the disk near the head. The shock from these organs, which may reach 220 volts and is strong enough to fell a human adult, is used for defense, sensory location, and capturing prey
gamma ray: Electromagnetic radiation emitted by radioactive decay and having energies in a range from ten thousand (10) electron volts. a beam of light with a short wavelength, that can pass through solid objects radi'ation. Penetrating very short-wavelength electromagnetic radiation, similar to an X ray but of higher energy, that is emitted spontaneously by some radioactive substances (see gamma decay, radioactivity). Gamma radiation also originates in the decay of certain subatomic particles, and in particle-antiparticle annihilation (See also antimatter). Gamma rays can initiate nuclear fission, can be absorbed by ejection of an electron (see photoelectric effect), and can be scattered by free electrons (see Compton effect)
gamma-ray astronomy: Study of astronomical objects and phenomena that emit gamma rays. Gamma-ray telescopes are designed to observe high-energy astrophysical systems, including stellar coronas, white dwarf stars, neutron stars, black holes, supernova remnants, clusters of galaxies, and diffuse gamma-ray background radiation found along the plane of the Milky Way Galaxy. Because Earth's atmosphere blocks most gamma rays, observations are generally conducted by high-altitude balloons or spacecraft. In the 1960s defense satellites designed to detect X rays and gamma rays from clandestine nuclear testing serendipitously discovered enigmatic gamma-ray bursts coming from deep space. In the 1970s Earth-orbiting observatories found a number of gamma-ray point sources, including an exceptionally strong one, dubbed Geminga, that was later identified as a pulsar, the nearest yet detected. The Compton Gamma Ray Observatory, launched in 1991, mapped thousands of celestial gamma-ray sources; it also showed that the mysterious bursts are distributed across the sky, implying that their sources are at the distant reaches of the universe rather than in the Milky Way
