Jean-Baptiste Biot

Born 21 Apr 1774; died 3 Feb 1862 at age 87. French physicist and mathematician who, with Felix Savart, developed the Biot-Savart law, that the intensity of the magnetic field produced by current flow through a wire varies inversely with the distance from the wire. He did work in astronomy, elasticity, heat, optics, electricity and magnetism. In pure mathematics, he contibuted to geometry. In 1804 he made a 13,000-feet (5-km) high hot-air balloon ascent with Joseph Gay-Lussac to investigate the atmosphere. In 1806, he accompanied François Arago to Spain to complete earlier work there to measure of the arc of the meridian. Biot discovered optical activity in 1815, the ability of a substance to rotate the plane of polarization of light, which laid the basis for saccharimetry, a useful technique of analyzing sugar solutions.«

Family Bible

A little boy opened the big and old family Bible with fascination, looking at the old pages as he turned them. Then something fell out, and he picked it up and looked at it closely. It was an old leaf from a tree that had been pressed in between the pages.

“Momma, look what I found,” the boy called out.

“What have you got there, dear?” his mother asked.

With astonishment in the his voice, he answered, “It's Adam's Suit!”
