Re: A Challenge to mathematical physicists

In Einstein's 1905 equation tau = a(t - vx'/{c^2 - v^2}), where did
the "a" come from and what does it signify; and IF it IS "a function
phi{v) at present unknown" WHAT is its value if, as he later said,
"phi(v) = 1"? >
tau = a(t - vx'/{c^2 - v^2})
is the general solution to the partial differential equation:

Um, no. It's not energy, either. That goes in a different term. Bzzt.
Please try again.
Understood, but general relativity is not Newtonian gravity. And so a
feature that is special to general relativity does not imply anything
about Newtonian gravity. Bzzzt. Please try again.
Now, THIS is funny, since he was the one that proposed it. Yet now you

Recall energy and mass being equivalent? So, in this case, it is.
<shrug>
Just what part of Newtonian law of gravity do you not understand?
Positive mass yields gravity according to the Newtonian law of
gravity. This indicates and leads to the consequence of negative mass
yielding antigravity. <shrug>

Hey, asshole:
Your mistery has been solved.!
You have stated, among other things that:
1) You are better, smarter than everyone here. Hundreds of years ahead.
2)That many here are dishonest.
3)That many here purposely hide the truth.
4)That many here belong in jail.

usher Paraphrase: I Decide for others in sci.math what is important

2010-03-11T18:42:54Z

Asshole usher, who cannot find employment as a writer anywhere --even in today's Internet world -- has taken to hurling his vapid, insipid , OT feces , which, again, no one is interested-enough in for him to get a job as a writer, on sci.math.
usher's justification.?
(paraphrase) the issues I address are more important than mathematics.

--- --- --- consistency of an equation.

2010-03-11T18:44:22Z

Consider equation (1) below under the given conditions.
x^k + (1/4)y^k = 0 mod(k^2) (1)
Conditions: k is prime to xy, y is even, both x, y are integers and
each > 1, prime k > 3
Question: Is (1) consistent?
Any helpful comments with a numerical example will be appreciated

Re: Usher:" Fuck Sci.math: I post whatever I like in here, even if it is OT

2010-03-11T18:37:24Z

Usher is disingenuous --flat-out dishonest-- enough to pretend he is not implicitly giving the finger to sci.math, by posting all his OT-garbage in here.
Usher's implied message is: "I know this site was intended mostly for mathematics, but I don't care, I will use it for my purposes, at others' expense ."

Re: What the FUCK does this have to see with mathematics, ASSHOLE

2010-03-11T18:30:53Z

Go post your garbage somewhere else, you worthless
FUCK.
If you had anything of relevance to say, you would
have most likely found someone to hire you and pay you.
Since you have not, the odds are that you do not, so you post to unmoderated sites.
The odds are, too, that you are 50+ , and still living in mom's basement.

Did the author already show that coproducts are disjoint and universal in
a topos? In this case assemble your maps as follows

are these facts about prime ideals true?

2010-03-11T18:18:36Z

I was wondering if someone could confirm that the following facts
about prime ideals are true or let me know if they are not...
1. In a Noetherian ring, is the infinite intersection of powers P^n
of a prime P equal to 0?
2. Let R be a commutative ring, let P be a prime ideal, and let m be a
positive integer. Let a and b be elements of R. Suppose that a lies in

Thanks a lot.
I believe the lemma; however I could be even more wrong than you. I
was also concerned about this other fact which I am not sure of: In a
Noetherian ring, is the infinite intersection of powers P^n of a prime
P equal to 0?
I mgiht make a different psot with these two questions and maybe

Re: completion

2010-03-11T17:52:18Z

What I understand is the "completion of R at the ideal J" is the
inverse limit of the rings R/J^n, with n=1, 2, ... etc.
That is, the subring of the product Prod(R/J^n), n=1,2,3,...,
consisting of all coherent sequences, (a_1, a_2, ..., a_n,...) where
a_{n+1}=a_n (mod J^n); if we think of a_i as elements of R, then we

What does it tell you when, to make a proof work, you have to do
something illegal?
Let's see what happens if we only allow legal operations. Assume x
is real. If x^2 - 10x = - 40, then
0 = x^2 - 10x + 40
= x^2 - 10x + 25 + 15

Would you be kind enough to state the problem that you believe that you
have solved? If it is a simple matter of finding roots of x^2-10x=-40
then your various strange manipulations have not provided you with such
roots.
