A joke mathematicians tell -- request for source 
  There's a joke (easily googlable) about a rabbit who writes a Ph.D thesis saying that rabbits eat foxes (sometimes it's wolves). I've heard this joke a few times in maths circles but there's no maths content to it. Does anyone know the source/origins of this joke? Paul Epstein

Question about Base 
  My apologies if this type of question is inappropriate here, especially since it's the other end of the spectrum from your normal discussions, but I could find no other group where someone might be helpful. Has there ever been a system in BaseX where X is also a digit? (i.e. a Base3 where counting is: 1, 2, 3, 11, 12, 13, 21 . . .)... more »

Exponential Equation - How do you solve this one please? 
  Hi Everyone, I am challenged today by trying to find a solution to this equation. Am I missing something, or is this a tough one. There is only one variable, W, all the others are constants (C,D,E,F,G) E = F*exp(CW) + G*exp(DW) I'm seeking W=? The only thought I had was taking the derivative with respect to W and... more »
