### Mach 3 Bubble Shockwaves

Supercomputer simulations reveal the intricate density and vorticity patterns resulting from a Mach 3 shockwave hitting a helium bubble.### Back To The Moon For Good – The New Space Race

Watch our cool movie about going back to the Moon. In case you haven’t heard, the Moon is trending again… and in a big way. Narrated by Tim Allen (voice of Buzz Lightyear), this is a complete behind-the-scenes feature on the $30 million Google...### MIT 8.224 Exploring Black Hole by Prof. Edmund Bertschinger

This is the first video of the second lecture in this beginner's course on Algebraic Topology. We give the basic definition of homeomorphism between two topological spaces, and explain why the line and circle are not homeomorphic. Then we introduce...
