Try to solve the buried treasure riddle: https://www.youtube.com/watch?v=tCeklW2e6_E 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. Lesson by Jeff Dekofsky, animation by The Moving Company Animation Studio.
