Another game called X-it (I apologize if the name "X-it" is already the name of a game somewhere, which it must be. But a search for 'X-it game' on Google didn't bring anything up in the first couple pages of results.) This is a game for any plural number of players. Start with a grid of n-by-n squares ((n+1)-by-(n+1) lines) drawn on p... 14 Jul 2010 10:58
reverse limit If f is a continuous function on a compact space X, (sj)_j a sequence within X and (f(sj))_j -> y, is there some x with f(x) = y? Would addition of hypothesis such as Hausdorff, normal, 1st countable (or even metric if need be) ease or settle the issue? ... 15 Jul 2010 00:11

number example to show how Infinitude of Twin Primes works #651 Correcting Math Alright I gave this as an example of how Regular primes infinitude proof works in Indirect: Euclid Infinitude of Primes proof, Indirect in short- form with number example of 3 and 5 : 1) Definition of prime 2) Hypothetical assumption, suppose set of primes 3,5 are all the primes... 12 Jul 2010 03:05
IF SKEPTICS ARE SO GREAT.... Why is there a 50,000 km^2 pile of SLUDGE heading towards James Randi Educational Foundation? Another one of those PATTERNS I'm seeing... Watch out SKEPTOS...

THE SILENT END OF EINSTEIN'S RELATIVITY Einstein's relativity started with the rejection of Newton's thesis that the speed of light varies exactly as the speed of cannonballs does: http://www.amazon.com/Relativity-Its-Roots-Banesh-Hoffmann/dp/0486406768 "Relativity and Its Roots" By Banesh Hoffmann "Moreover, if light consists of particles, as Einstei... 9 Aug 2010 11:13
Are space and time separate issues that can be treated in a parallel way. Consider that at least 99% of 'matter' at your density is 'empty' space. Then what does it mean that string theory implies 8 or 9 spatial dimensions. Then what does it mean that 'time' is being recognized as a quale, a brain based representation, no more 'real' than 'red'. Very mysterious place. ... 12 Jul 2010 14:03

Are space and time separate issues that can be treated in a parallel way. If there is a arrow of time is there a arrow of space? If there is a "temporal becoming" is there a "spacial becoming"? Time has only one dimension while space has three, and that physical events presuppose both space and time while mental events presuppose, directly at any rate, only time. There are, howeve... 13 Jul 2010 18:38
Proof of the Infinitude of Twin Primes and all even numbered pairs of primes Due to a conversation with a journal editor, my interest has been rekindled in a proof of the Infinitude of Twin Primes and all even numbered pairs of primes.
