 Jean-Baptiste Biot Jean-Baptiste Biot (April 21 1774, Paris – February 3 1862, Paris) was a French physicist and mathematician who in the early 1800s studied the relationship between electrical current and magnetism (see Biot-Savart Law), as well as the polarisation of light passing through chemical solutions. He was the first person to discover the unique optical properties of mica, and therefore the mica-based mineral biotite was named after him. In 1804 he made a hot-air balloon ascent with Joseph Gay-Lussac to a height of five kilometres in an early investigation of the Earth's atmosphere. There is a small crater on the Moon that is named for him. See alsoExternal links
