In some class notes I found those conditions interpreted as a "five requirements on Hamiltonian of physical system":
1. Unitarity -> Hamiltonian has to be hermitian operator
2. Claster decomposition (microcausality and locality) -> (? missing part)
3. Poincare invariance -> Hamiltonian...
Accepted, of course. After such nice and honest explanation I feel sorry to make eventually additional unnecessary pressure on you. Especially because you partly have right in accusing me for not so polite entrance.
However, hope you going better this evening.. and best wishes for tomorrow...
Or you just miss my point - word "kids" is referred to football player lectures part, and should be understand as some kind of joke (see wink at the end), and allusion that scientists degree in phyiscs doesn't mean degree in design. To prove you that I was not "pretentious" I suggest that you...

Of course, content is what matters, but this...

To be more specific, my questions are related on "Classical Electrodynamics", Jackson 2nd edition, Sect. 4.2. (and 4.1 of course), titled "Multipole expansion of the Energy of a Charge...
