Through the centuries, Italy gave birth to some notable scientific minds. One of the most notable, and perhaps the most famous polymath in history, Leonardo da Vinci made several contributions to a variety of fields including art, biology, and technology. Galileo Galilei was a physicist, mathematician, and astronomer who played a major role in the Scientific Revolution. His achievements include improvements to the telescope and consequent astronomical observations, and support for Copernicanism. The physicist Enrico Fermi, a Nobel prize laureate, was the leader of the team that built the first nuclear reactor and is also noted for his many other contributions to physics, including the co-development of the quantum theory. Other notable figures include the astronomer Giovanni Domenico Cassini, who made many important discoveries about the Solar System; the physicist Alessandro Volta, inventor of the electric battery; the mathematicians 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; the biologist Lazzaro Spallanzani, who conducted important research in bodily functions, animal reproduction, and cellular theory; and Guglielmo Marconi, who received the Nobel Prize in Physics for the invention of radio.
