- "Well Galileo postulated that two objects of the same density, in this instance the density of iron, fall at the same rate even though they are of very different size and weight."
- ―Miss Seymour teaching Indiana Jones at Pisa[src]
Galileo Galilei was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. His achievements include improvements to the telescope and consequent astronomical observations and support for Copernicanism. Galileo has been called the "father of modern observational astronomy," the "father of modern physics," the "father of science," and "the Father of Modern Science".
Miss Seymour spoke of Galileo while teaching Indiana Jones physics at Pisa in 1908. Later in Florence, she spoke of how Galileo constructed the first complete astronomical telescope and contributed towards proving that the Earth was not the center of the universe.
