The Fundamental assumption is that a system is equally likely to be in any accessible quantum state. • The ergotic hypothesis says that the time average of a quantity is equivalent to the ensemble average.

# Average Energy per EM Mode2 - Essay - Physics

This calculation was first performed before by Rayleigh and Jeans in about 1900, before the advent of quantum mechanics.

# Gaussian Distribution - Essay - Physics

Where  is the standard deviation. The area under the curve between ± occupies 68.3% of the total area. ±2 occupies 95.4%, and ±3 occupies 99.7%. This is a way of determining the accuracy of a given measurement. Problem is that everyone assumes...

# Legendre Transformations - Essay - Physics

The time average of P i piri is 0. The quantity could be periodic, as in the case of central potentials. Otherwise, assume it is bounded, so its time average is 0. It is not meaningful to talk about the time average of an unbounded system, so the...
