Extractions: Home Encyclopedia Summa Fathers ... B > Jean-Baptiste Biot A B C D ... Z Biot was actively engaged in the various branches of the geodetic work involved in the famous measurement of the quadrant of a meridian, for the purpose of standardizing the length of the new unit, the meter. As a member of the Bureau of Longitudes he went, in 1806, with young Arago, to Formentera, in the Balearic Islands, to resume the measurement of a degree of the meridian, interrupted by the death of Mechian. In 1808 he determined, with Mathieu, the length of the seconds pendulum at Bordeaux and Dunkirk. In 1817 he went to Scotland and the Shetland Islands to verify the geodetic operations of the English under Colonel Mudge. In 1824 he returned to Italy, Sicily, and Spain, in order to correct some of the observations of the year 1808. He contributed more than 250 memoirs to various societies and periodicals. This enormous work covers the entire field of experimental and mathematical physics, as well as ancient and modern astronomy. He was the champion of the corpuscular theory of light which he extended to some most ingenious explanations of the very complex phenomena of polarization. Biot discovered the laws of rotary polarization by crystalline bodies and applied these laws to the analysis of saccharine solutions. His fame rests chiefly on his work in polarization and double refraction of light. Regular habits of study and recreation kept him in good health and led to a ripe old age. His mental attitude may be indicated by his opposition to the open meetings of the Academy; he feared the influence of the vulgar public upon the scientific tone of the Institute. Since he was brought up in the turbulent times of the

Mémoire sur un nouveau genre d'oscillation que les molécules de la lumière éprouvent en transversant certains cristaux ... Lu à l'institut le 30 novembre 1812. Paris, Firmin Didot, 1814. 4to, pp. [iv], 371, with 2 folding engraved plates; the initial four leaves minimally soiled; a very good, uncut copy in contemporary marbled boards, spine damaged, corners rubbed. FIRST EDITION, VERY RARE. 'His most important work [is] the study of polarization of light, the research for which Biot was awarded the Rumford Medal in 1840 by the Royal Society of London. The polarization of light by reflection had been discovered by Malus in Paris in the fall of 1808 ... Malus' discovery opened up an entirely new field of research, and no one was more stimulated than his two associates in the Arcueil group, Arago and Biot' (DSB). Biot carried out various experiments on the ratio between the thickness of crystal plates, and the colours produced by light passing through. Exact measurements and observations enabled him to discover that the colour of light sent through crystalline plates 'depended on the thickness of the crystal traversed by the refracted ray and varied as the square of the sine of the angle that the direction of the ray formed with the optical axis. 'Biot's interpretation of his results was in terms of a repulsive force that caused polarization by acting on the particles of light. This conception was first worked out in detail in a memoir presented to the first Class on 30 November 1812. The discovery of polarization had greatly encouraged Laplace, Biot, and others who supported a corpuscular theory of light' (ibid.).

http://micro.magnet.fsu.edu/optics/timeline/people/biot.html

Extractions: Jean-Baptiste Biot was a physicist and mathematician who made advances in geometry, astronomy, elasticity, magnetism, heat and optics. For his work on the polarization of light passing through chemical solutions, Biot received the Rumford Medal from the Royal Society in 1840. Biot's father was a treasury official who had planned for his son to enter the world of commerce. Biot was provided with a private math tutor in his youth and was educated at the college of Louis-le-Grand before joining the French army in 1793. After serving briefly in the artillery, he enrolled at the Polytechnic School in Paris. He later moved to Beauvais to act as a mathematics professor, but returned to Paris in 1800 when he was given the position of chair of mathematical physics at the College de France. Elected to the French Academy of Sciences at an unusually young age in 1803, that same year Biot was sent to investigate objects falling from the sky. His findings helped initiate the general acceptance of the existence of meteorites. Then, in 1804, he accompanied Joseph Gay-Lussac on the first balloon trip undertaken for scientific purposes. Biot's interest in optics was spurred in 1806 when Thomas Young revived the wave theory of light. The resurgence of the theory divided the great physics minds of the day into two separate camps, one that supported the wave theory, and another that believed in the corpuscular nature of light. Biot, a member of the latter group, began devoting his time to developing mathematical support for the idea that light existed as particles. In 1808, experiments performed by Etienne-Louis Malus showed that reflected light became polarized, a finding that could only be explained by the wave theory of light. However, Biot chose to repeat and expand upon the work of Malus in hopes of attaining validation for the opposing light theory.
