Brutal section on kinetic theory: the key is to understand the underlying statistical arguments, independent of the physics, then come back and realise you're doing nearly the same thing to a vector distribution which happens to have a physical meaning, as you were doing to a scalar probability distribution. Then apply a bunch of vector calculus tricks that allow you to get some really clever results.
I almost skipped the orbit theory chapter (same old same old) but I'm glad I didn't because it's very clear on relativistic limits to the theory, stuff you don't typically see elsewhere. The derivation of the Fokker-Planck equation from kinetic theory is also very good. If this book was converted to SI Units it would be brilliant, going by the evidence so far.
The first chapter is a very mixed bag:
Negative: "mixed cgs-Gaussian" units. Muddled and contradictory definition plasma. (The "fourth state of matter"/ionised gas definition is wrong and should be dropped.) Counter-intuitive notation.
Positive: Detailed discussion of collision frequencies, does not assume singly ionised heavy ions, quantitative definitions of quasi-neutrality, relativistic and classical limits.
