What is relativity? “When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That’s relativity,” according to Einstein himself. This little anecdote jokingly illustrates one of the cornerstone predictions of both special and general theories of relativity — time dilation. Even though these impressive theories have offered physicists some other crucial insights into the nature of the laws of physics, time dilation is in many ways the most breathtaking one, having played a crucial role in undertaking the Newtonian view of the Universe as the dominating one.
In this video we have Dr. Jürgen Renn delivering a special evening talk about the evolution and historical significance of Einstein’s theory of general relativity, where he points out other examples of the revolutionary significance of relativity. As always, for more videos use the links below.
