Italophilia priest and mathematician, born in 1598, is known for his work on indivisibles, a precursor of infinitesimal calculus, and for Cavalieri's principle in geometry, which partially anticipated integral calculus. Alessandro Volta, born in Como in 1745, invented the first true electrical battery, known as the voltaic pile. It provided a continuous source of electric current, which greatly benefitted Ampere, Ohm and other electrical experimenters in their development of basic electrical theory. A unit of electricity (volt) is named in his honor. Italians such as Fallopio, Eustachi, Malpighi, Morgagni and Valsalva were important pioneers of modern anatomy at the University of
Georg Ohm Georg Ohm Georg Simon Ohm (; ; 16 March 1789 – 6 July 1854) was a German physicist and mathematician. As a school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relationship is known as Ohm's law. Georg Simon Ohm was born into a Protestant family in Erlangen, Brandenburg-Bayreuth (then a part of the Holy Roman Empire), son to Johann Wolfgang Ohm, a
