In canonical ensemble all energy values are permitted.
The distribution of energies of system at temp T follows Gibbs Distribution.
My question is simple.
Why is it that all energies are permitted??
forget the mathematical derivation.
How to understand it physically.
Does it not take the...
Is the lagrangian always K.E-PE?
I don't think so?
so WHAT REALLY is the physical significance of the lagrangian?
Superficially it appears to be KE-PE,but the lagrangian for a charged particle in a vector potential is 1/2MV.V +qV.A-qW.
