Science and technology in Italy various astronomical observations, and initial formulation of the first and second laws of motion. Galileo was suppressed by the Catholic Church, but was a founder of modern science. The astronomer Giovanni Domenico Cassini, who made many important discoveries about the Solar System; the physicist Alessandro Volta, who invented the electric battery, thus providing for the first time a sustained source of current electricity; the mathematicians Giuseppe Peano, Lagrange, Fibonacci, and Gerolamo Cardano, whose "Ars Magna" is generally recognized as the first modern treatment on mathematics, made fundamental advances to the field; Marcello Malpighi, a doctor and founder of microscopic anatomy;
Alessandro Volta Law of Capacitance, and it was for this work the unit of electrical potential has been named the volt. In 1779 he became a professor of experimental physics at the University of Pavia, a chair that he occupied for almost 40 years. Luigi Galvani, an Italian physicist, discovered something he named, "animal electricity" when two different metals were connected in series with a frog's leg and to one another. Volta realised that the frog's leg served as both a conductor of electricity (what we would now call an electrolyte) and as a detector of electricity. He replaced the frog's leg
