what group theory ex.?

@Marc, good luck
Nov 1, 2010 19:37
I asked them to give us LaTeX in here but I don't think they will
Nov 1, 2010 19:36
hello
Oct 31, 2010 15:00
hey Weltschm here is a problem: is there a power of two which has all the digits 1,2,3,4,5,6,7,8,9 in it an equal number of times?
Oct 31, 2010 14:59
Actually you might get something nice out of [a][bc][d][ef][g]
Oct 31, 2010 14:58
if you are in groups of two then it might 99 and 101
Oct 31, 2010 14:57
ah 9 and 11 are special because that's -1 and 1 mod 10
Oct 31, 2010 14:56
there's no reason why that wouldn't give a new divisibility test for something
Oct 31, 2010 14:55
that would be like kl + hij * 10^2 + fg * 10^5 + cde * 10^7 + ab * 10^10
Oct 31, 2010 14:55
it would be interesting to see if you can get some results out of [ab][cde][fg][hij][kl] though
Oct 31, 2010 14:54
I thought of it as (1) turning 9385450 into [9][38][54][50] and (2) turning it into [9][385][450] to get two different divisibility tests
Oct 31, 2010 14:52
yeah but what do you interpret that as meaning
Oct 31, 2010 14:50
Weltschm what do you mean by divide in groups of 2 and 3
Oct 31, 2010 14:48
that's better
Oct 31, 2010 14:48
1896246 is divisible by 33 because 1+89+62+46 is
Oct 31, 2010 14:45
oops, it's not that simple.
Oct 31, 2010 14:44
393 is divisible by 3 because 3+9+3 is. 273459 is divisible by 30 because 27+34+59 is.
Oct 31, 2010 14:41
I need to get that book
Oct 31, 2010 12:13
well you are beating me :p

hi Debanjan
Oct 31, 2010 01:07
Bye
Oct 31, 2010 00:34
I've not read it yet
Oct 31, 2010 00:06
quite a job to LaTeX all this stuff up but many people will be thankful if you do :p

The especially nice thing about Eulers papers is he is very keen on describing the methodology
Oct 30, 2010 23:59
J. M. - yes I get far too distracted with that when I read Gauss
Oct 30, 2010 23:57
I just read about that thing recently so I am still thinking how neat it is
Oct 30, 2010 23:56
what's really cool is that Baker used the same idea on the cubic version to bound integer solutions of a cubic
Oct 30, 2010 23:55
if x/y is close to sqrt(2) then sometimes we might have x^2 = 1 + 2 y^2
Oct 30, 2010 23:55
crasic, the idea is that - to solve x^2 - 2y^2 = 1, well you find a good approximation x/y to sqrt(2)
Oct 30, 2010 23:51
it seems like any equation I can solve, say congruences or pell or whatever.. it's been done to death - and the equations nobody solved are way too difficult for me
Oct 30, 2010 23:50
one thing I wonder about number theory is how do you solve a new equation?
Oct 30, 2010 23:49
I meant more that I couldn't even get into the basic books on it
Oct 30, 2010 23:36
I would post analysis questions regarding fractals but I couldn't even get started -_-
Oct 30, 2010 22:45
that sounds a lot like the quantum logic gates
Oct 30, 2010 22:35
well I suppose Lie groups in the classical mechanics, Noethers theorem
Oct 30, 2010 22:34
I don't know any applications of group theory in physics
Oct 30, 2010 22:32
it is great fun
Oct 30, 2010 22:32
you can teach yourself Galois theory
Oct 30, 2010 22:32
what algebra are you doing?
Oct 30, 2010 22:13
"After Albert Einstein came up with the theory of relativity people in the social sciences such as the German sociologist Max Weber, again applied the concept of relativity to concepts such as morality. Thus appeared the concept of moral relativism in which morality simply becomes what a particular society believes is moral." - mypracticalphilosophy.com/shelp/moralrel.htm

Newtons 3rd law "The mutual forces of action and reaction between two bodies are equal, opposite and collinear"
Oct 30, 2010 22:02
LOL
Oct 30, 2010 22:02
Obviously Newton developed his theory of physics in line with the Christian philosophy of "Do unto others as you wish they do unto you" in mind
Oct 30, 2010 22:01
"However, now armed with relativity, facts are no longer absolute, but instead dependent upon your viewpoint, your own "philosophical" inertial reference frame"
Oct 30, 2010 22:00
"Prior to relativity, philosophers such as Aristotle, Kant, and Mill argued that there was an absolute truth and an absolute way of approaching various aspects of life" - scienceinsociety.northwestern.edu/content/articles/2008/…

haha that's clever
Nov 1, 2010 19:37
Please can we have $\LaTeX{}$ supported in the math chat room :P
Oct 30, 2010 22:34
I wish we could do $\LaTeX{}$ in the mathematics chat....
