Would it be copyright infringement to simply copy formulae from


no. you can't copyright equations. you can derive them first and get them named after you, but after that anyone can use them.

Diffraction equation!! biggrin
d sin(theta) = n (lambda)


Lorentz Transformations:
(gamma) = 1/(1-Vrel^2)^(1/2)

t' = -(Vrel)(gamma)x + (gamma)t
x' = (gamma)x - Vrel(gamma)t
y' = y
z' = z

v = (v' + Vrel)/(1+ v'*Vrel)


Modern Physics!

Compton Effect: (lambda2) - (lambda1) = (h/mc)(1-cos(theta))
deBroglie Wavelength: (lambda) = h/p = hc/E

Classical Wave Equation: (dy/dx)^2 = (1/v^2)(dy/dt)^2
y = y0 cos (kx-wt)
w = 2*pi*f
k = 2*pi/(lambda)


Schrodinger Equation:

1-D: -(h-bar)^2/(2m) (d (Psi of x and t)/dx)^2 + V(x,t)(Psi of x and t) = i(h-bar) d(Psi of x and t)/dt

that doesn't look nearly as neat when you have to spell out greek characters and the like.

I'd do the 3-D, but it wouldn't look pretty. So...I'm done.


I liked modern physics. It was cool.

So... how about updating those UNDER CONSTRUCTION sections? Don't mean to rush ya.

care to help? I forget what program Layra-chan is using, but she can probably tell you and I think it's downloadable. All you have to do is prepare the equations, send them to me via pm, and I can edit her posts.

I'd like to help too, if possible.

If a function f(x) is homogeneous of degree k, then:

What about the Maxwell Distribution Equation or Statistical Distributions? Those are intensely useful.

The derivative of an function is f'(x) = (f(x+h) - f(x)) / h
The indefinite integral (or anti-derivative) of a function is derived by reversing the derivation process of a function, but adding a constant.
[e.g. - the anti-derivative of f(x) = x is (1/2)x^2]

Good 'ole green's theorem.

f(max static)=U(static)F(normal) = static friction
U(static) = f(max static)/F(normal) = static friction coefficient
F(normal)= f(max static)/U(static) = normal force

f(kinetic)=U(kinetic)F(normal) = kinetic friction
U(kinetic)= f(kinetic)/F(normal) = kinetic friction coefficient
F(normal force) = f(kinetic)/U(kinetic) = normal



F(blah) = F(sub whatever)
