Galileo's Construction of Idealized Fall in the Void (2005)


The article contends that there are alternative interpretation of Galileo's idealized claims about falling bodies. The paradox of heavy bodies and continuous motion in accelerated fall was the original question motivating Galileo's work. It argues that Galileo's 1604 hypothesis of the sameness of ratios of speeds and spaces is fully compatible with his previous analysis of accelerated motion. Grappling with the paradox, he realized that weight cannot be the cause of a body's speed of fall, and that all bodies somehow become "weightless" while falling in the void. The resolution of the paradox could lead to a "new science of motion". Galileo applied proportional reasoning based on Euclid's Elements.
