MALUS, ETIENNE LOUIS
MALVACEAE, in botany, an order of Dicotyledons belonging to the series Columniferae, to which belong also the orders Tili— aceae (containing Tilia, the lime-tree), Bombaceae (containing Adansonia, the baobab), Sterculiaceae (containing Theobroma, cocoa, and Cob, cola-nut). It contains 39 genera with about 300 species, and occurs in all regions except the coldest, the number of species increasing as we approach the tropics. It is represented in Britain by three genera: Malva, mallow; Althaea, marsh-mallow; and Lavatera, tree-mallow. The plants are herbs, as in the British mallows, or, in the warmer parts of the earth, shrubs or trees. The leaves are alternate and often palmately lobed or divided; the stipules generally fall early. The leaves and young shoots often bear stellate hairs and the tissues contain mucilage-sacs. The regular, hermaphrodite, often showy flowers are borne in the leaf-axils, solitary or in fasicles, or form more ,n-..~ or less complicated cymose 14~~ ~‘~‘f arrangements. An epicalyx (see

    malus, etienne louis (17751812). French physicist who discovered the polarizationof light by reflection from a surface (see polarized light.
    http://www.cartage.org.lb/en/themes/Biographies/MainBiographies/M/Malus/1.html
    Malus, Etienne Louis French physicist who discovered the polarization of light by reflection from a surface (see polarized light. He also found the law of polarization that relates the intensity of the polarized beam to the angle of reflection.
    Malus was born in Paris and studied there at the Ecole Polytechnique. From 1796 he was in the army, taking part in Napoleon's campaign in Egypt and Syria in 1798 and eventually rising to major, but he was also an examiner for the Ecole Polytechnique.
    Malus began doing experiments on double refraction in 1807. This phenomenon causes a light beam to split in two on passing through Iceland spar and certain other crystals. An empirical description had been given by Dutch physicist Christiaan Huygens, based on the assumption that light is wavelike in character, and Malus's results confirmed Huygens's laws.
    In 1808, Malus held a piece of Iceland spar up to some light reflecting off a window. To his surprise, the light beam emanating from the crystal was single, not double. He then noted that of the two beams that normally emerge from the crystal, only one was reflected from a water surface if the crystal was held at a certain angle. The other passed into the water and was refracted. If the crystal was turned perpendicular, the second beam was reflected and the first refracted. He described the light as being 'polarized'.

    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.
