some backtracking in deriving speed of light from purely math considerations ; speed of light Chapt 19 #194; ATOM TOTALITY
Archimedes Plutonium wrote: (all else snipped) --- derivation of speed of light out of pure math ---  Earlier I wrote how the speed of light in physics should be derived  out of pure math  as that of Stripe Geometry on the surface of Earth where I take all  the meridians  as stripes and w... 23 Jun 2010 15:05

Help with a Diophantine system in four variables?
Hello all, Can anyone find another solution to, a + b + c + d = x^2 a^2+b^2+c^2+d^2 = y^2 a^3+b^3+c^3+d^3 = z^3 other than {a,b,c,d} = {10, 13, 14, 44}? - Titus ... 24 Jun 2010 06:22

Mersenne primes
This fails for 2047 = 23 x 89. The number 2048 will not appear in this table. Taking m>n, and making rows in the triangle by m, then for n=0 (the smallest entry in a row) T(m,n)=2m. That means if 2048 is to appear, it must appear in the first 1024 rows. It does not. Checked by Mathematica: Input: TAB = Flat... 23 Jun 2010 12:52

PRIMAILTY TEST DONE FOR ANY NUMBER - HOPE RESEARCH ANNOUNCEMENT---
Very Simply we have the capability today of taking any Number no matter how large, and within minutes be able to confirm if that is a prime number . This is done by computer reverse program. As to primality formula by Hand, this will take time, it is complex, but it is mathematically possible, if one calculat... 23 Jun 2010 11:44

Vedic astrology is not intuition of Rishis.!!
This is a commentary on the above email story and it is very interesting. After reading the last emails circulated by some organisations, it is reassuring to feel like a proud indian, until one realises that the assumptions in these articles are based on myths and blind faith. Such emails are circulated repea... 23 Jun 2010 22:47

Different take on birthday problem
Hi, I would like to ask your help in coming up with an answer to the below, which appears in a way an inverse birthday problem... An answer so far has been elusive, and been the subject of many a coffee corner speculation... We have a system with a population of (N) 4000000 users, with each user having a self gen... 23 Jun 2010 23:53

Archimedes Plutonium wrote: (snipped) Any and every sphere has lines of longitude and a log spiral to the poles that is a 1/8 circumference representative. Any and every sphere has band-meridians or stripe-meridians. We ask the question, what is the Minimum speed at which you can cover that sp... 23 Jun 2010 05:09

Represenative of ideal class group.
Hi~ I have a question in algebraic number theory. It is known that the ideal class group of a number field is finitely generated abelian group and so it is isomorphic to the direct product of finite cyclic groups. Then, for each cyclic component of ideal class group, is it possible to choose a prime ideal r... 23 Jun 2010 15:05
