Did Galileo Really Drop Leaning Tower Pisa

Between 1589 and 1592, the Italian scientist Galileo Galilei (then professor of mathematics at the University of Pisa) is said to have dropped two spheres of different masses from the Leaning Tower of Pisa to demonstrate that their time of descent was independent of their mass, according to a biography by Galileo’s …

Why was Galileo unable to perform a true free fall experiment?

Galileo’s inability to make direct measurements to test his hypothesis-that Dv/Dt is constant in free fall-did not stop him. He turned to mathematics to derive from this hypothesis some other relationship that could be checked by measurement with equipment available to him.

Why was Galileo correct?

Galileo Galilei made many scientific discoveries, but three were very significant. He discovered that the planets and other astronomical bodies did not orbit the Earth, they mainly orbited the Sun, and the moons of each planet orbited the planet itself. Next, Galileo discovered the phases of Venus.
