More generally, if f(u) is any function of u, then the mean value of f(u) is defined
by /M-^ (1-3-2) i = l This expression can be simplified. Since P(ui) is defined as a
probability, the quantity M P(m,) + P(us) + • • • + P(uM) = 2 PM i-1 represents the ...
Another useful mean value is V □ M (Am)2 = ^ P(ud(ui - uY > 0 (1-3-9) i-l which is
called the "second moment of u about its mean," or more simply the "dispersion of
u." This can never be negative, since (Am)2 > 0 so that each term in the sum ...
Frederick Reif. 1. There is an intrinsic increase A -^ in the total mean value of x
due to the fact that the quantity x(»",e,<) for each molecule in d'r changes. In time
dt, each molecule changes position by dr = v dt and velocity by dv = (F/m) dt; ...
