That's amazing. It just goes on and on with beautiful plots. About halfway down, there's a section on understanding the Riemann sphere:<p>> From what I can tell, one of the settings used to deal with division by 0 is the so-called Riemann sphere, which is where we take a space shuttle and use it to fly over and drop a cow on top of a biodome, and then have the cow indiscriminately fire laser beams at the grass inside and around the biodome. That's my intuitive understanding of it anyway.<p>And there's even animation (with Mathematica source) for this one. However:<p>> (Note the cow cannot be spherical or it will roll off).
