PeroK reacted to James Demers's post in the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it? with
Like.
This is a bit of an over-simplification, but essentially you have 18 variables: 3 bodies x (3 velocity vectors + 3 coordinates)... -
PeroK reacted to Dale's post in the thread I Conventionality of the One-Way Speed of Light with Like.
The conventionality of the one way speed of light (OWSOL) was recognized from the very beginning. In the seminal paper On the...

PeroK reacted to Muu9's post in the thread Need a book on Modern Physics to supplement Griffiths QM with Like.
I was hoping you would go through the effort of doing that for us. Something something burden of proof...

PeroK reacted to MidgetDwarf's post in the thread Need a book on Modern Physics to supplement Griffiths QM with
Skeptical.
Maybe have a look at Townsend and McTyre book? Then look at Griffiths? The difference is night and day. -
PeroK reacted to Demystifier's post in the thread I Does action at a distance violate any conservation principles? with Like.
But on the other hand, the quantum potential in Bohmian mechanics is neither time-translation nor space-translation invariant, so one...

PeroK replied to the thread B Newton's first law?.In the 1905 paper, Einstein says "Let us take a system of co-ordinates in which the equations of Newtonian mechanics hold good." This...
-
In newtonian physics, the 1st Law describes bodies that are not accelerating. There is no net external force acting on it. There...

PeroK replied to the thread Study: Social media probably can’t be fixed.It's a reference to The Forbibben Planet (1956). The Krell civilization built a machine that granted their every wish. But, when they...

PeroK replied to the thread Study: Social media probably can’t be fixed.They'll not feel so bad, seeing it happening to us as well!
-
PeroK replied to the thread B Newton's first law?.It makes no difference. I guess, if you were starting at the beginning, then the body would have no forces acting on it. After you've...

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
Informative.
It is interesting to know that the first computers (e.g. the ENIAC) were built specifically to conveniently calculate non-analytical... -
PeroK replied to the thread Study: Social media probably can’t be fixed.The monster from the id has been loosed.

PeroK reacted to Filip Larsen's post in the thread Study: Social media probably can’t be fixed with Like.
As one who has never really used social media and thus been a bit baffled at the public discussion of the toxicity and other issues they...

PeroK replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.PS the ancient Greeks were obsessed by rational numbers and didn't like it when irrational numbers starting popping up. We know that no...
