    Extractions: ibn-al-Haitham (965-1039) also known as Alhazen was a mathematician whose main contribution was the study of optic. In his treatise on optics, translated into Latin in 1270 as Opticae thesaurus Alhazeni libri vii, Alhazen published theories on refraction, reflection, binocular vision, focussing with lenses, the rainbow, parabolic and spherical mirrors, spherical aberration, atmospheric refraction, and the apparent increase in size of planetary bodies near the Earth's horizon. He was first to give an accurate account of vision, correctly stating that light comes from the object seen to the eye. One of his celebrated problem is the so-called 'Alhazen's problem': At which point on a spherical mirror is light from a given point source reflected into the eye of a given observer? In Opticae Thesaurus, introduced the idea that light rays emanate in straight lines in all directions from every point on a luminous surface. In Epitome of Astronomy , he took a position against Ptolemy, insisting that the hypothetical spheres corresponded "to the true movements of really existing hard or yielding bodies [and] so...were accountable to the laws of physics" (Duhem 1908:28). This led to disagreements that persisted through the twelfth century.

Hofstadter lehrte zwischen und an der Universit¤t Stanford . Zur Messung und genaueren Erforschung der Bestandteile von Atomkernen verwendete er dort einen linearen Elektronenbeschleuniger. Seinerzeit hatte man Protonen und Neutronen und Elektronen noch als strukturlose, das heiŸt unteilbare Teilchen betrachtet. Mit seinen Experimenten konnte Hofstadter nicht nur die AusmaŸe von Protonen und Neutronen exakt bestimmen, sondern auch nachweisen, dass beide einen positiv geladenen Kern besitzen, der von einer doppelten Wolke von

    Extractions: Robert Hofstadter, 1961 UPI/Corbis-Bettmann (b. Feb. 5, 1915, New York, N.Y., U.S.d. Nov. 17, 1990, Stanford, Calif.), American scientist who was a joint recipient of the Nobel Prize for Physics in 1961 for his investigations of protons and neutrons, which revealed the hitherto unknown structure of these particles. He shared the prize with of Germany. Hofstadter was educated at Princeton University, where he earned a Ph.D. in 1938. As a physicist at the National Bureau of Standards during World War II, he was instrumental in developing the proximity fuse, which was used to detonate anti-aircraft and other artillery shells. He joined the faculty of Princeton in 1946, where his principal scientific work dealt with the study of infrared rays, photoconductivity, and crystal and scintillation counters. Hofstadter taught at Stanford University from 1950 to 1985. At Stanford he used a linear electron accelerator to measure and explore the constituents of atomic nuclei. At the time, protons, neutrons, and electrons were all thought to be structureless particles; Hofstadter discovered that protons and neutrons have a definite size and form. He was able to determine the precise size of the proton and neutron and provide the first reasonably consistent picture of the structure of the atomic nucleus. Hofstadter found that both the proton and neutron have a central, positively charged core surrounded by a double cloud of pi-mesons. Both clouds are positively charged in the proton, but in the neutron the inner cloud is negatively charged, thus giving a net zero charge for the entire particle.

    Extractions: Hofstadter, Robert US nuclear physicist who made pioneering studies of nuclear structure and the elementary nuclear constituents, the proton and the neutron. He established that the proton and neutron were not pointlike, but had a definite volume and shape. He shared the 1961 Nobel Prize for Physics. Hofstadter was born in New York and educated at City College and Princeton. From 1950 he was at Stanford, where his early work involved bouncing, or scattering, electrons from complex nuclei, such as gold. This produced accurate pictures of the charge distribution within nuclei. Gradually, smaller nuclei were studied by Hofstadter and his team, using electrons of increasing energy. By 1960, accurate data had been obtained for the proton and neutron, revealing the spatial distribution of charge and magnetization within these particles.
