He fled to England in 1776 and studied projectiles. He was elected to the Royal Society in 1779. After a brief return to America, he was knighted, and appointed adviser to the Elector of Bavaria. there he reformed the army, set up welfare schemes for the poor, bred stronger horses and cattle and laid out the English Garden in Munich. He also showed, by studying the boring of cannons, that heat was due to the motion of particles in a body.

Sir Charles Wheatstone (1802-1875), British inventor. He is best known for the Wheatstone Bridge, a device for determining the resistance of an electrical component. Wheatstone was a child prodigy, and by 15 he was translating French, including a book on electricity by Volta. Aged 19, he took over the family business of making musical instruments, but devoted his time to experiments rather than business. He made important contributions to spectroscopy, telegraphy, the physics of electricity, and even cryptography.

Charles Robert Darwin. Darwin (1809 - 1882), British naturalist, argued the theory of natural selection in his book "Origin of Species" (1859). While he was not the first to suggest the idea of evolution, he was the first to prove it with proper scientific study and argument.

Charles Darwin (1809-1882), English naturalist and author of the Origin of Species. He suggested that natural variation in a species creates a wide range of individual characteristics some of which are more useful than others. The competition to survive in nature provides adriving force for evolution in the form of natural selection, a mechanism which weeds out those individuals possessing traits less suitable to the enviroment. The implications of his theory to man's own origins fuelled a bitter controversy with the church. Stipple engraving by C.H. Jeens from a photograph by O.G. Rejlander, about 1874.

Claudius Ptolemy (AD c100-170), Greek-Egyptian astronomer, geographer and mathematician at his observatory in Alexandria, Egypt. Among the instruments seen here are Ptolemy's rulers (lower center) and a copper disc (far right), which he used to demonstrate the law of reflection. At this observatory Ptolemy made the observations that supported Earth-center models of solar and planetary motion. This view dominated astronomical thinking until the mid 16th century. Engraving from Vies des Savants Illustres (1877).
