Transform -- the game This is a game for any plural number of players. (No grids this time, sorry.) There are a number of rounds in this game. The number of rounds is a multiple of the number of players. The players take turns being "the permutator", where each player is the permutator the same number of rounds. Before starting an... 19 Jul 2010 08:03
stats/probability question I'm an engineering undergrad in an intro stats course. We had a question in the book that's really dumb. problem as stated: Your candidate has 55% of the votes in the entire school. But only 100 students will show up to vote. What is the probability that the underdog (the one with 45% support) will win? T... 19 Jul 2010 06:59
(1) + (1+1/4) + (1+1/4+1/9) + ...= gamma(-1) ? As I asked in the subject - is that a meaningful description for the gamma(-1)-infinity? (1) + (1+1/4) + (1+1/4+1/9) + ...= gamma(-1) and more, (1) + (2+1/8) + (3+2/8+1/27) + ...= gamma(-2) These formal equalities stem from the continuation of the eulerian triangle to negative row-indexes. (It is... 16 Jul 2010 13:15

Conjecture or theorem? Conjecture or theorem? "The set of prime numbers are divisors of the set of Fibonacci numbers" I found that the primes <=113 (Except 103), are divisors of some of the Fibonacci's <= Fi(90). Can anybody continue searching? Ludovicus ... 17 Jul 2010 00:12
Frechet derivative in c0 space Hi I'm trying to solve this problem for a long time now, so if you could help, I would appreciate it. F:c_0->c_0 F({x_n})=(cos(n*x_n))/n I know, that gateaux derivative (in direction {y_n}) is {(- sin(n*x_n))y_n}, but I can't proof anything about the Frechete derivative (which I think doesn't exist) c_0 is... 16 Jul 2010 11:01

Can we safely ignore contradictions? Hi! I've been doing some reading lately where the authors seem to say that when contradictions arise in various disciplines of Mathematics and Science we can ignore them, because they really don't affect much of anything in their disciplines, and even somehow have a stimulating effect in their fields. Is thi... 16 Jul 2010 11:01
Is space covariant or contravariant? I often meet the question whether the (physical) space is 'covariant' or 'contravariant'. I once replied to that question with: Space is space. The components of a tensor are covariant/contravariant if the basis is CHOSEN TO BE contravariant/covariant. As far as I know tensors the 'covariance' or 'contravariance' o... 16 Jul 2010 08:48 |
