Two great discoveries of the past that you may not know [History]
posted March 5 2014 15:04.35 by Giorgos Lazaridis




Adam Savage walks through two spectacular examples of profound scientific discoveries that came from simple, creative methods anyone could have followed: Eratosthenes' calculation of the Earth's circumference around 200 BC and Hippolyte Fizeau's measurement of the speed of light in 1849.

As a Greek I already knew about Eratosthenes (as I owed to) so I was not really impressed, but hey, the calculation of the speed of light by Fizeau back in 1849 really thrilled me!
