I have added a new forum for discussions about math. If your having trouble with a derivative, integration, simple algebra, or adding the fingers on your hand then someone here should be able to help.

As with all categories, please be specific in your subject when you post. Just writing "HELP!!!" will lead to a slower response time and frustrated moderators.

Try "Having trouble with second derivative of Lennard-Jones potential", or "I know I should have ten fingers, by I only count eight."

And please try to use the fancy math buttons when posting equations. Always put all math between two [ tex] tags like so:

Code:

I think this equation is super groovy:

[tex]E_{quation} = super^{groovy}[/tex]

It will look much cooler like this:

$E_{quation} = Super^{groovy}$

I want to know if this can be rigth:

"GUT

Analising an hipotetical situation that a body is alone on universe with its on eletromagnetical and gravitational field in balance of forces.
Suddenly… Big Bang. And all mass is tranformed into ligth. What happens so…
foloweling the theory of conservation of mass:

Emag = Egra

So,

q x K / d2 = m x G / d2

m = q x K / G

We can say that if we don´t look at time, by its relativity, and compare galaxies and other sistems in iqual form, with the peculearities, it can be used in chemistry or others concepts and truths.
We can conclued this philosophical theory saying: “If we get together all knowledge of universe we can understand this theory in its on magnitude”."

$\Sigma_{0}^n x^2$

$\frac {h^2} {8 \pi^2 m} \nabla^2 \Psi + V \Psi = \frac {h} {2 \pi i} \frac{\par \Psi}{\par t}$

This is Schrodingers Equation!

$h$ = planks constant

If this is true then wouldn't $(h h^2) = h^3$ then $8 \pi ^2 m \nabla^2 (\Psi + \Psi) + v = \frac{(\hbar^2 - \hbar)} {2 \pi i} \frac{\par \Psi} {\par t }$ ?
