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;
Volta potential Volta potential The Volta potential (also called Volta potential difference, contact potential difference, outer potential difference, Δψ, or "delta psi") in electrochemistry, is the electrostatic potential difference between two metals (or one metal and one electrolyte) that are in contact and are in thermodynamic equilibrium. Specifically, it is the potential difference between a point close to the surface of the first metal, and a point close to the surface of the second metal (or electrolyte). The Volta potential is named after Alessandro Volta. When two metals are electrically isolated from each other, an arbitrary potential difference may exist between them.
