Here, < sub > n </ sub > denotes the sample mean of the first n samples ( x < sub > 1 </ sub >, ..., x < sub > n </ sub >), s < sup > 2 </ sup >< sub > n </ sub > their sample variance, and σ < sup > 2 </ sup >< sub > n </ sub > their population variance.

The quantum number n first appeared in the Bohr model where it determines the radius of each circular electron orbit.

Initially, it was relatively unsuccessful, staying at the charts for only one week, but Haley soon scored a major worldwide hit with a cover version of Big Joe Turner's " Shake, Rattle and Roll ", which went on to sell a million copies and became the first ever rock ' n ' roll song to enter British singles charts in December 1954 and became a Gold Record.

This number can be seen as equal to the one of the first definition, independently of any of the formulas below to compute it: if in each of the n factors of the power one temporarily labels the term X with an index i ( running from 1 to n ), then each subset of k indices gives after expansion a contribution X < sup > k </ sup >, and the coefficient of that monomial in the result will be the number of such subsets.

Bernoulli numbers feature prominently in the closed form expression of the sum of the m-th powers of the first n positive integers.

The first and second Bernoulli numbers now follow by setting n = 0 ( resulting in B < sub > 1 </ sub >=−, " first Bernoulli numbers ") respectively n = 1 ( resulting in B < sub > 1 </ sub >=+, " second Bernoulli numbers ").

from which it is clear that and for k > n. To see that these coefficients count k-combinations from S, one can first consider a collection of n distinct variables X < sub > s </ sub > labeled by the elements s of S, and expand the product over all elements of S:

This means that the shortest program to output the first n bits of Ω must be of size at least n-O ( 1 ).

A real number is called computable if there is an algorithm which, given n, returns the first n digits of the number.

The proof of this fact relies on an algorithm which, given the first n digits of Ω, solves Turing's halting problem for programs of length up to n. Since the halting problem is undecidable, Ω can not be computed.

Given the first n digits of Ω and a k ≤ n, the algorithm enumerates the domain of F until enough elements of the domain have been found so that the probability they represent is within 2 < sup >-( k + 1 )</ sup > of Ω.

As mentioned above, the first n bits of Gregory Chaitin's constant Omega are random or incompressible in the sense that we cannot compute them by a halting algorithm with fewer than n-O ( 1 ) bits.

After finite time the first n bits of the output will never change any more ( it does not matter that this time itself is not computable by a halting program ).

It was originally one of between 50 to 70 verses of a song titled " Jerusalem, My Happy Home " that first appeared in a 1790 book called A Collection of Sacred Ballads:
