A simple proof of FLT
I would like to see a simple proof of FLT. Is there any theoretical reason why a simple proof of FLT cannot exist? ... 12 Jul 2010 17:24

OFFICIAL - 170 MILLION LIST OF PURE PRIME NUMBERS AND PLACEMENT TO BE POSTED AT SCI MATH TOMMOROW
The 170 million pure Prime numbers produced by special mathematics and placement computer program discovered at Hope research are a first in Mathematics, and within a month a "billion numbers" will be available, from the Computer programs at Hope research, after we get access to the needed computers. This is bas... 17 May 2010 12:26

Lipschitz Functions and Riemann Integral
Hello, let R be the field of real numbers. Does there exist some Lipschitz function g:[a,b]->[c,d] and some bounded function f:[c,d]-> R wich is Riemann integrable such that f°g is not Riemann integrable? Thank you very much for your attention. My Best Regards, Maury Barbato PS If one only supposes that g i... 21 May 2010 20:33

Spiral of Theodorus Maple animation question
Hi, I'm writing an animation of the Spiral of Theodorus. I'm trying to get it to display a composition of the triangles as it animates. If i change the code to insequence=false it displays them all at once, and doesn't animate. Here is the little bit of code I wrote: g := sum(arctan(1/sqrt(n)), n = 1 .. i)... 17 May 2010 13:32

Chapt10; fiberglass/prism experiment, and eclipse-test to tell with moving towards Earth #91; ATOM TOTALITY
Now I failed to mention what happens when a white light headlight of a car is moving away from me, the observer with a fiberglass panel. For obvious reasons I did not include that because there are no cars with white taillights. So I am assuming that if there were white taillights and thus viewed through the fibe... 17 May 2010 04:48

Analytic solution of this recurrence equation in complex Z-plane?
Hi. Can one find an analytic solution to the recurrence functional equation F(z+1) = z F(z) + 2 F(z-1) - (z-4) F(z-2) - F(z-3) F(0) = 1, F(1) = 0, F(2) = 0, F(3) = 1 in the complex z-plane? Can such a solution be expressed in closed form using generally-accepted mathematical special functions, even if it i... 17 May 2010 00:31
