100 years of relativity and enthusiasm for bringing science to the pu

25. Time and space are celebrating their 100th wedding anniversary. To mark the centenary of relativity theory, Anais Rassat and her cross-Channel accomplices have put Einstein front and center in an entertaining animated film. The EPFL physicist explains her approach. On November 25, 1915, Albert Einstein presented his theory of general relativity at the Prussian Academy of Science. Time and space became just two sides of a single coin, and we never saw things in quite the same way again. The Universe got a birthday with the Big Bang, GPS satellites that use the same equations could be developed, much to drivers' delight, and the portrait of the physicist sticking his tongue out has become the iconic image of the genius.
