PeroK replied to the thread A. R. Chohan, Independent Researcher.The Special and General theories of Relativity are 120 and 110 years old respectively. There's nothing deeper to find now. One area of... -
PeroK reacted to GlitchedGluon's post in the thread B What's Delaying Fermilab's Muon g-2 Results Release? with
Informative.
What do you mean? I think there is a whole section in the White Paper discussing different procedures to average those results. It seems... -
PeroK reacted to GlitchedGluon's post in the thread B What's Delaying Fermilab's Muon g-2 Results Release? with Informative.
The whole Section 3 is dedicated to discuss the lattice results. There are several tables showing the different contributions along with...

PeroK reacted to Demystifier's post in the thread I Wigner's friend and quantum tunneling with
Like.
I think you are missing the point of thought experiments. Their main point is to better understand the theory, not to learn something... -
PeroK reacted to A.T.'s post in the thread B Time dilation for two clocks at different altitudes on Earth with Like.
Two meetings are required if the clocks are in relative motion at some point. If their arrangement remains static permanently (in some...

PeroK replied to the thread I Wigner's friend and quantum tunneling.Would that apply to Schrodinger's cat as well? You cannot isolate the cat and the decoherence must leak out to the laboratory?

PeroK reacted to Demystifier's post in the thread I Wigner's friend and quantum tunneling with Like.
I can have it both ways, to understand it one just has to be a little bit more precise. First let me define 3 systems I am talking...

PeroK reacted to Ibix's post in the thread I How does GR deal with pointlike objects with mass? with Like.
The statement is that you can't tell the difference between being stationary on a planet's surface and being under acceleration in flat...

PeroK replied to the thread I How does GR deal with pointlike objects with mass?.The equivalence principle in this case is for local experiments over a short period of time. The equivalence between local gravity and...

PeroK replied to the thread Calculating ##\langle zHz \rangle## in different ways.I thought it was a reference to Arsenic and Old Lace, where Peter Lorre's character implores his accomplice to do the killing "ze kveek...

PeroK reacted to mitchell porter's post in the thread I "Violation of the Equivalence Principle in Disk Galaxies" newly interpreted with Informative.
This is a response to an article from five years ago (Chae et al 2020) claiming to detect an effect of MOND (the "external field...

PeroK reacted to MidgetDwarf's post in the thread Quantum mechanics book recommendations with Informative.
If you are struggling with the mathematics of Griffiths, then you do not meet the math prerequisites. It is probably the most math hand...

PeroK replied to the thread Calculating the Planck Length.In answer to your question, the Planck length, as far as I know, is defined to be: $$l_p = \sqrt{\frac{\hbar G}{c^3}}$$I think it's...
