The Contributions of John Philoponus

@RonSewell

Thank you for pointing out John Philoponus. I was unaware of his contribution to the concept of inertia well prior to Galileo.

@Jonathan_Burke

Several groundbreaking contributions to physics, including the all important principle of inertia.

I don’t know about the other claims, but Philoponus did not come up with inertia, rather the theory of impetus. Philophonus’ impetus is very different from inertia, and regardless the theory of impetus was already “discovered” ~600 years before Philophonus by Hipparchus.
