n↑(r)+n↓(r)≡2n0; however there is a spin polarization (A.7) Since F(x)≈cosx/x3 for large x, we see that the spin polarization is of long-range nature, oscillates with distance and falls off with the inverse cube power law r-3 at large distances; notice the analogies between...
Math Formula to compute the Difference Between Sum of Squares and Square of the Sum We know the Sum of first N Natural numbers is: . It would be great if we can find out the formula for the sum of squares. Let’s assume is it (the sum of squares) . The first few values: With ...

+nk, so it is the sum of the k-th power of all natural numbers up to n. In this problem you are about to compute, f(1) + f(2) + f(3) + ... + f(n) Input The first line is an integer T (1 ≤ T≤ 54,321), denoting the number of test cases. Then, T test cases...
[5] then studied the structure of long unsplittable minimal zero-sum sequences over 〚〛〚−m,n〛 with n≥m2/2−1 and m≥6, where a minimal zero-sum sequence S over 〚〛〚−m,n〛 is called unsplittable if there exist no 〚〛x,y∈〚−m,n〛 and a term ...
In fact, quantitative findings of any material and energy changes preserve their full context only through their being seen and understood as parts of a natural order. — Walter Hess First sentence of 'The Central Control of the Activity of Internal Organs', Nobel Lecture (12 Dec Dec 1949)....
A natural question is: what if we have several ( n > 2) variables with known distribution, we have no information about their correlation, and we are interested in possible probability distribution for the sum y = x 1 + + x n? Known formulas for the case n = 2 can be (and have ...

The vector product is given by a× b = ab sin (θ)nˆ, where a and b are the magnitudes of the vectors a and b, θ is the angle between them, and nˆ is a unit vector normal to the plane of a and b. If a and b are vectors in the x, y plane, that is, a = (a1...
