His importance to the history of science depends on his De motu naturaliter accelerato (1640), in which he showed himself to be the only mathematical physicist of the time who understood precisely Galileo's reasoning in rejecting the proportionality of speeds in free fall to the distance traversed. Another book, Traité des quantitez incommensurables, which concerns the foundations of algebra, stood as a final attempt to preserve the classical Greek separation of arithmetic from geometry.
