There’s just one problem: they don’t work. Why not? Netta Schramm describes the pitfalls of perpetual motion machines. Lesson by Netta Schramm, animation by TED-Ed.

There is absolutely no doubt that after Newton, Einstein is the most popular physicist in the history of science. Between the March and June of 1905, Einstein, then a mere patent clerk, published four papers that revolutionised modern physics forever. Although he became a household name for discovering the ever-famous E=mc2, it was time dilation that completely changed our understanding of space and time. What's more, the principle occurred to him in a daydream. Watch our new video to understand what is time dilation and find out why your head is older than your feet!

The Infinite Hotel, a thought experiment created by German mathematician David Hilbert, is a hotel with an infinite number of rooms. Easy to comprehend, right? Wrong. What if it's completely booked but one person wants to check in? What about 40? Or an infinitely full bus of people? Jeff Dekofsky solves these heady lodging issues using Hilbert's paradox.
