Shut Up and Calculate!

An ideal rotation around the point at infinity in the disc and upper half plane model of the hyperbolic plane

Trippin’ so hard right now! Maths is better than any hallucinogen.

If you have a cat, you’ll get this!

Mine does this every single morning. Minus the baseball bat of course.

There are a bunch of more Simon’s Cat videos here. Enjoy!

Oh my god this is so amazing I can’t even… *physicsgasm*

The Three-body Gravitational Interaction has gotta be my favourite. So pretty!

This is slightly related to my previous post.

(From source):

Animated 3D projection of a 4D rotation of the 600 cell. While it may look like a simple 3D rotation, that is an illusion - it uses a 4D rotation matrix. There are 3 sets of 45 frames each. Each set rotates through 2Pi on the XW plane. The second set adds (using a dot product on each rotation matrix of the first) a rotation through Pi on the YW hyperplane. The third set adds to the second a rotation through Pi/2 in the ZW hyperplane.

This makes my brain hurt. Pretty though! :)
