[Combinatorics] Ball choosing
Hi, there. Here is my question: Given n balls numbered 1 to n and choose m balls from them, then what is the probability of existing k balls with consecutive numbers in those m balls? Thank you~ ... 7 Jun 2010 08:32

Quadratic Iteration
The "only" complex quadratic iteration is z->z^2+c, all else you can transform into that...but only if the function is analytic. Drop that: x->a1x^2+a2y^2+a3xy+a4x+a5y+a6 y->b1x^2+b2y^2+b3xy+b4x+b5y+b6 Again, obviously you can transform x=p1X+p2Y+p3,y=q1X+q2Y+q3 but in mopping up I lost oversight :-) Surely a4=a... 7 Jun 2010 07:26

Inconsistency of Special Relativity and Doppler Effect Chapt 8 #143; ATOM TOTALITY
So, you have one class in college physics where the professor is saying that Special Relativity SR, comes down to where the speed of light is a constant in all inertial reference frames, meaning that c + v = c and where c - v = c where c is the speed of light and v is a speed added or subtracted on. And SR is e... 7 Jun 2010 03:07

initialize a list S to contain one element 0.Re: Transitivity: how to prove it?
I'm specifying an operation on transitive relations for a discrete-mathematics software library. Suppose I have a relation R = (G, A, A) which is transitive, i.e.: for all x, y, z in A: xRy and yRz ==> xRz Now suppose I have an operation on such transitive relation: R' = R.transtivively_includin... 7 Jun 2010 19:58
