PeroK replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.The problem is that there are hardly any standard functions: polynomials, trig functions, exponential and logs. That's about it. There... -
PeroK reacted to Dale's post in the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it? with
Like.
It is already solved. The solution is just not analytic. -
PeroK replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.What I do with these problems is try to think them through first. My instinct is forget formulas for now and try to figure out what...

PeroK replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.I once heard the analogy that studying systems with analytic solutions is a bit like studying a single animal, like the elephant. And...

PeroK reacted to Muu9's post in the thread Need a book on Modern Physics to supplement Griffiths QM with Like.
Which math? Linear algebra and bra ket notation?

PeroK replied to the thread I Does action at a distance violate any conservation principles?.Naively, instantaneous action at a distance ensures conservation. Newton's theory of gravity being a prime example. In particular...

PeroK reacted to MidgetDwarf's post in the thread Need a book on Modern Physics to supplement Griffiths QM with
Skeptical.
It doesn't shy away from the mathematics. Griffiths does. While still being explanatory. It overlaps with the more sophisticated... -
PeroK reacted to Herman Trivilino's post in the thread A Charge to mass ratio of a photon with Like.
Charge to mass ratio applies only to particles that have both charge and mass. It makes no sense to speak of the charge to mass ratio of...

PeroK reacted to PeterDonis's post in the thread I Does action at a distance violate any conservation principles? with Like.
But such influences are not directly observable. All directly observable results are in accordance with standard QM. Standard QM obeys...

PeroK reacted to vela's post in the thread Need a book on Modern Physics to supplement Griffiths QM with Like.
Then I think it would help, as @robphy suggested above, if you could give us an example of a roadblock you're running into. Maybe you...
