p. 162. Galileo's early yearslocked

  • Stillman Drake


‘Galileo's early years’ provides an insight into Galileo's childhood and early work. Galileo was born in Pisa, and attended the University there. He became chair of mathematics at Pisa where he wrote the unpublished De Motu, which contained the first seeds of his departure from Aristotle. He then became professor of mathematics at Padua, where, in 1595, he came upon an explanation for the tides using the Copernicus' ideas, rather than the accepted Ptolemaic system. In 1602 Galileo derived his theories of motion from De Motu. The new basis for these discoveries was careful measurement. This began to replace the search for causes with the search for physical laws.
