Exactly why the theories of relativity are complete nonsense - the basic mistake exposed!
Dear All, I have been saying all this and much more for years, in Usenet and in public life! I had put up the above article in a website which was pulled down by Telstra for upgrades. Now, this article is back again, and I do hope it gives new, vibrant life to this deluded world. I am glad to see that my ... 25 Feb 2010 10:17

finding parametric equations
I have the following graph: http://i45.tinypic.com/14c5o2u.png and I am to find paramettric equations for the curve that consists of all possible positions of the point P in the image above, using the angle theta as the parameter. Also note, the line segment AB is tangent to the larger circle. (The inner circ... 3 Jan 2010 13:50

I saw this: http://en.wikipedia.org/wiki/Finite_difference#Calculus_of_finite_differences which shows that the "forward difference operator" can be expressed as a "Taylor series of operators" in the differentiation operator: Delta_h = hD + hD^2/2!... 2 Jan 2010 09:31

Nebular Dust Cloud where all the stars are "blue stars"; (use in 4th)
Now I am not saying that Nebular Dust Clouds never form stars. I am saying that 99% of the creation of stars and planets are formed by Dirac new radioactivities. Our own Solar System was formed by Dirac new radioactivities. There is a picture of a Nebular Dust Cloud which I had seen many years back in which ... 2 Jan 2010 03:08

A call for some useful primes for RNGs
With b=2^32-1, the following primes have b as a primitive root: 543213218b^128+1, 8007626b^128+1, 8006134b^256+1, 107982b^256+1, 123554642b^512+1, 70024066b^512+1, 123471786b^1024+1, 1030770b^1024+1, 1030770b^2048+1, 914646b^2048+1, 18782b^4096+1 They are among many I have found as p=ab^r+1, with... 30 Dec 2009 08:43

3D Star of David space filler based on truncated tetrahedrons.
buncha wordgoo about Higgs "doublets," but, at least, you are in the correct mode to speak of 4d-ness of *space*, with the tetrahedron -- not "tine-space" of Minkowski's late outburat! In my chiral space filling example there are two elements. 1; regular tets or tetrahedrons which are rotated relative to each... 27 Dec 2009 16:18

how do i know that data lie in linear subspace or not?
I have some data, and I want to reduce the dimension at first, if the data lie in linear subspace, I can use PCA, otherwise I can use manifold or something esle, but how do i know that data lie in linear subspace or not? does anyone know it? Thank you! ... 28 Dec 2009 18:30

Okay, and I am sorry someone defaced your other thread, but what is your [b]point[/b]? Yes, 2^19+ 2^19= 1048575 but that is NOT any integer to the 19 th power. It is about (2.0743100888923839722774500511128)^19 but Fermat's theorem requires a^n+ b^n= c^n for a, b, c, and n all positive integers. ... 26 Dec 2009 07:51
