Comparison of the antiquated view and the outcome of the experiment (size of the spheres represent their masses, not their volumes) Between 1589 and 1592, [1] the Italian scientist Galileo Galilei (then professor of mathematics at the University of Pisa) is said to have dropped "unequal weights of the same material" from the Leaning Tower of Pisa to demonstrate that their time of descent was ...
The Assayer (Italian: Il saggiatore) is a book by Galileo Galilei, published in Rome in October 1623.

The Discourse on Comets (Italian: Discorso delle Comete) was a pamphlet published in 1619 with Mario Guiducci as the named author, though in reality it was mostly the work of Galileo Galilei. In it Galileo conjectured that comets were not physical bodies but atmospheric effects like the aurora borealis. [1]: 62
De motu antiquiora [1] ("The Older Writings on Motion"), or simply De Motu, is Galileo Galilei's early written work on motion (not to be confused with Newton's De motu corporum in gyrum, which shares the abbreviated name, De Motu). It was written largely between 1589 and 1592, [2] but was not published in full until 1890. [3]
