@johncarlosbaez @simsa03 Yes, #Oresme was quite interesting. I know him for two other achievements:
1. Relativity of motion: He had already the famous “ship argument” that #Galileo used to show that physics in a moving object must be the same as in a standing one — the only difference is that Oresme, living in Paris, used a ship on a river and not on the sea. (https://todayinsci.com/O/Oresme_Nicole/OresmeNicole-Forerunner.htm)
2. He proved the divergence of the harmonic series. (https://en.wikipedia.org/wiki/Nicole_Oresme#Mathematics)
