Aristotle's failure to do the simplest experimental verification of his theories resulted in 2000 years of ignorance which remained unchallenged until Galileo combined experiment and mathematics to form the cornerstones of modern science. This video looks at what became the foundation of Galilean Relativity, which formed the launch pad for Einstein's own Theory of Relativity many years later.

Due to inertia the ball returns back into the cart unless we are conducting the experiment outdoors on a windy day :)
