Spherical Geometry Is Stranger Than Hyperbolic
He has a cool video on how hyperbolic geometry is really big: https://www.youtube.com/watch?v=zQo_S3yNa2w
⬐ ruytlmAt 5:45[0] in that video, he makes a reference to one of the greatest weird explanations of video game things ever: the explanation[1] of how to beat the Watch for Rolling Rocks level in Super Mario 64 with only half an A-press, which is highly worth a watch if you like this stuff about geometry.And if that was interesting, I also recommend the history of any percent speed runs for Super Mario Sunshine.[2]

⬐ peter_d_shermanThis is amazing!This video compares and contrasts three different types of Geometries:
o Spherical Geometry
o Euclidian Geometry (the one we all know)
o Hyperbolic Geometry
With the wonderful property that
Spherical Geometry is sort of the opposite of Hyperbolic Geometry...
(Note to self, have to do more research on this!), i.e.,
Circumference of a circle:
Spherical: 2 x pi x sin(r)
Euclidian: 2 x pi x r
Hyperbolic: 2 x pi x sinh(r)
