Re: Using GR to explain time dilation.

You are a dreamer, Ken. You are a student that embraces nonsense.
<shrug>
You are wrong once again as usual. The geodesic equations describe
how a particle moves in curved space or spacetime as observed by an
observer using that said coordinate system and nothing else, and the
twin's paradox deals with unrealistic and contradictory time flows of

Re: Question about coordinate systems used to explain general relativity

The concept of curved space was first proposed by Gauss. It was his
student Riemann who was able to describe the curved space in
mathematics. So far, it is still simple mathematics. Riemann also
proposed gravity being the manifestation in the curvature of space,
and that did not go anywhere. It was after Minkowski showing how all

paraboloid centre of gravity

williamsdavi...@gmail.com (dow) — Sun, 21 Mar 2010 22:39:12 UT

A friend of mine wants to build a cooker powered by solar heat. He
wants to use a paraboloidal reflector, with the cooking pot at its
focus. Of course, the reflector has to move, to follow the sun across
the sky, but preferably the pot should not move, so the reflector must
turn about an axis that passes through its focus. He wants a simple

Let I be an open interval, SA(I,n) the set of selfadjoint n×n matrices
with spectrum in I, and f:I-->R k times continuously differentiable.
Is it true that the function A-->f(A) defined on SA(I,n) is k times
Frechet-differentiable. If so, how can it be proven?

Good basic math textbook?

glowingface...@gmail.com (Glowing Face Man) — Sun, 21 Mar 2010 22:07:07 UT

Hi,
I get asked this a lot and don't really know any good answers besides
maybe Euclid's Elements-- "What's a good basic math book for self-
taught math for people who don't know anything about math?"
I'm thinking maybe something pre-calculus? Since it's self-taught, a
textbook which assumes the reader is smart and competent and

Re: Einstein Was Right: General Relativity Confirmed

koobee.wub...@gmail.com (Koobee Wublee) — Sun, 21 Mar 2010 21:53:36 UT

You can score whatever you like. At the end of the day, Einstein was
merely a nitwit, a plagiarist, and a liar. <shrug>
The nitwit had nothing to do with both the special and the general
theories of relativity except through plagiarism. <shrug>
Special Relativity is merely an interpretation to the mathematics of

Looking for formula to find out the maximum number of balls to take out

ckwig...@gmail.com (Clara) — Sun, 21 Mar 2010 21:44:59 UT

Hi maths geniuses,
I have a question. If I have for example 35 balls in a box and there
are 8 different types of balls in that box (ball1, ball2, ball3,
etc.). What is the maximum number of balls that I can take out from
the box to make sure that I have still 5 type1 balls in the box?? Is
there a formula that I can use to calculate this??

On Solving a System of Linear Congruences

berndlos...@gmail.com (Bernd L) — Sun, 21 Mar 2010 20:57:21 UT

Suppose I have a system of m equations in k unknowns
a_11*x_1 + a_12*x_2 + ... + a_1k*x_k = 0 (mod d)
...
a_m1*x_1 + a_m2*x_2 + ... + a_mk*x_k = 0 (mod d)
with the restriction that 0 <= x_n < n. How do I solve such a thing?
Will Gaussian elimination work? What if I get a solution where one of
the x's is outside its bounds?

Where c, is the speed of light.
Such that,
9x10^16/2(1.5x10^16) = 3x10^32
= 9x10^16/3x10^16 = 3x10^32
= 3x10^32 = 3x10^32
