Beta Epsilon Gamma Gamma Alpha Rho Sigma was created on 1923-12-20.
We have Lennard-Jones Potential given by, U=4epsilon[{(sigma/R)^12}- {(sigma/R)^6}] At equilibrium, dU/dR=0 if U is minimum. Solving, we get U=-epsilon which is indeed the bottom of the potential well.
I'm going to let Paul A. Tipler (Aka my 50lb physics textbook) answer this one.First to explain why I (rotational inertia) is in the equation.T (not period, but tao, or torque) is defined as F x RBy Newton's second law F = ma, in a rotating body a = alpha x RF = m(alpha)Rif you multiply both sides by RF x R = m(alpha)R2Recall F x R is TT = m(alpha)R2Sum the torques in the entire bodySigma(T) = Sigma(mR2(alpha))Therefore I is defined as Sigma(mR2), or for a continuous object(a disk) I = the Integral of (R2dm)Therefore, Sigma(T) = I x alphaThis is analogous with Newton's second law: F = ma. Where in rotation F --> T, m --> I, a --> alpha
(1/4pi[epsilon]_0)*Q^2/2R This can be derived from the fact that a spherical shell seemingly has a potential of a point charge (that is, k*Q/R) and W =½ int Vdq, where dq can be replaced with a [sigma]dA=[sigma] 4 pi r dr and sigma= Q/A = Q/4piR^2 => int½ Vdq = int ½k*Q/r*Q/(4piR^2)*4pir dr from 0 to R = k*½*Q^2/R^2 int dr from 0 to R = ½kQ^2/r=k*Q^2/2r.
Sigma Basically means the sum of something For Example: (sigma)F=ma This means the sum of the force acting on the object is equal to the mass multiplied by the acceleration!

The motto of Sigma Alpha Epsilon is 'Phi Alpha'.
When I was an undergraduate there in the late 1960's, Harvard had a chapter of Sigma Alpha Epsilon--which I believe was the only fraternity on campus. I'm not sure what the current situation is.
Actually the best place to get more information on "Sigma Alpha Epsilon" would be the related English Wikipedia page. The article is entitled accordingly "Sigma Alpha Epsilon".
Four chartered social fraternities, three colonies: Sigma Chi, Phi Gamma Delta (FIJI), Pi Kappa Alpha, Sigma Alpha Epsilon (currently suspended), Kappa Sigma (Colony), Alpha Tau Omega (colony), and Tau Kappa Epsilon (Colony).
