Introduction to Stat Mech

Alice in Boston is sending message to Bob in London. The number of bits in the message is much less (<<) than the number of bits required to transmit (\vec r_1, \vec r_2, ...\vec p_1, \vec p_2) = \delta N where N \sim \delta (10^23)

The "state of system" = F(N,T,V,...) \nequal f(time)

Need two ingredients

1. Microscopic description of system

2. Mech/Algorithm to find

Ergodrz Hypothesis

"There should be no time dependence."
