Home Encyclopedia Summa Fathers ... B > Jean-Baptiste Biot A B C D ... Z Jean-Baptiste Biot 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

Laplace In 1803 Biot was elected to the First Class of the Institute. Three years later he went with Arago to Spain to complete earlier work begun there on calculating the measure of the arc of the meridian. In 1809 Biot was appointed Professor of Physical Astronomy at the Faculty of Sciences. Biot studied a wide range of mathematical topics, mostly on the applied mathematics side. He made advances in astronomy, elasticity, electricity and magnetism, heat and optics on the applied side while, in pure mathematics, he also did important work in geometry. He collaborated with Arago on refractive properties of gases.

Paris, April 21, 1774, d. Paris, February 3, 1862] Biot was a physicist whose main discoveries affected astronomy, earth science, and chemistry. His 1803 report on a meteorite fall convinced scientists for the first time that rocks fall from the sky. His balloon flights with Joseph Louis Gay-Lussac established that Earth's magnetic field extends into the atmosphere. In 1815 Biot showed that some organic compounds have two chemically identical forms that rotate polarized light in different directions, correctly speculating that the effect is caused by differences in the shape of the molecules.

He taught mathematics at Beauvais before becoming (1800) professor of mathematical physics at the Coll¨ge de France and later (1809–49) of astronomy at the Sorbonne. With French physicist Fran§ois Arago , Biot measured properties of gases, and with French physicist Felix Savart, he formulated a law for the magnetic force near a wire carrying an electric current. He discovered that when light passes through some substances, including sugar solutions, the plane of polarization of the light is rotated by an amount that depends on the color of the light.

This view was verified by Pasteur . With Arago , Biot studied the optical refraction of gases. Biot also showed that the change in polarization found in light passing through materials was a rotation, and demonstrated that many liquid organic solutions exhibited this optical activity. In a textbook, he affirmed the importance of precise mathematical experimentation and measurement, which he presented as the paradigm of physics. Biot is also known for his ascent in a balloon loaded with scientific equipment which he undertook with Gay-Lussac .

He was the first person to discover the unique optical properties of mica , and therefore the mica-based mineral biotite was named after him.

Home Jean-Baptiste Biot 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.

Biot, Jean-Baptiste X1794 Professeur à l’Ecole centrale de Beauvais (1797), il devient examinateur d'admission à l'Ecole polytechnique de 1799 à 1806. Il est tout d'abord assistant de Laplace, puis un mémoire présenté à l'Institut lui vaut la chaire de physique mathématique au Collège de France en 1800 et l'Académie des sciences en 1803. Il prend part à l'ascension en ballon de Gay-Lussac (X1797) en 1804. Membre de l'Observatoire et astronome adjoint au Bureau des longitudes, il poursuit en Espagne, avec Arago (X1803), la triangulation de la méridienne en 1806, puis en Ecosse, aux îles Shetland, l'observation du pendule en 1817. Professeur d'astronomie physique de 1809 à 1816 puis en 1826 à la Sorbonne, membre de la Société royale de Londres en 1815, il découvre le pouvoir rotatoire moléculaire de certaines substances. Nommé au conseil de perfectionnement de l'Ecole polytechnique de 1816 à 1821, il est doyen de la Sorbonne de 1840 à 1849, membre libre de l'Académie des inscriptions en 1841 pour ses travaux sur l'astronomie des Egyptiens, puis de l'Académie française en 1856. Il travaille sur l'origine des météorites, le magnétisme terrestre, la lumière polarisée, invente le saccharimètre, et fonde avec Savart une loi sur les interactions entre aimants et courants.
