Dear Kostas: I tried stuff like: K[t]+I*Tau[t]=(x[t]+I*y[t])^n And then found that if the K[t[ had a sutraction and reduction it gave this. My other stuff was...
This kind of thought and some number theory stuff I've been working on made me think of this: Is the non-stopping of a Turing machine on a problem a...

General Relativity Tutorial - Torsion John Baez Oz asks: "Why do we assume [the connection] in GR is torsion free? A short couple of non-sarcastic...
The torsion tensor is very different than the Ricci tensor so a tensor version of the Serret-Frenet equations becomes very hard. In most cases general relative...

Try: dist[x]=Exp[-(x-1)2/2]/Sqrt[2*Pi] The idea is that your random is taken on the unit circle and the projective line is: a=Sin[2*Pi*Random[]]=2*x/(1+x2) ...
