PeroK reacted to songoku's post in the thread Limit of piecewise function using epsilon delta with
Like.
I am very sorry for late reply Thank you very much for all the help and explanation pasmith, PeroK, FactChecker, BvU, Gavran... -
PeroK replied to the thread I Physicists disagree wildly on what quantum mechanics says about real….So, physics has never been "intuitive" in the sense you demand. It's different to be guided by these things, than to demand that the...

PeroK reacted to PeterDonis's post in the thread I Physicists disagree wildly on what quantum mechanics says about real… with Like.
More precisely, our best current theories of physics do not contain any action at a distance, at least for one common meaning of that...

PeroK reacted to diogenesNY's post in the thread The Guardian Investigates Student Use of ChatGPT for 18 months with Like.
We are always fighting the last war.

You may want to read about geometrized units. Indeed, in this system Newton's universal gravitational constant ##G = 1##. I'd mentioned...

PeroK reacted to Herman Trivilino's post in the thread Reconcile poundforce w/slug and lbmass with Like.
You seem to be connecting the choice of units used to the validity of the science and engineering done with those units. There is no...

PeroK reacted to vela's post in the thread Confusion In Writing Identical Particle Wavefunctions with Like.
I don't get it either. I think he's wrong, but the same text is in the second edition. I would think that an obvious error like that...

PeroK replied to the thread B What is conformal time?.There's a discussion about how to calculate conformal time here. I'm not sure it meets your criterion of simple...

PeroK reacted to Demystifier's post in the thread A A global energy conservation law in general relativity with Like.
Of course there is, it is well known that one can construct an energy-momentum pseudo-tensor that leads to a globally conserved notion...

PeroK reacted to Herman Trivilino's post in the thread Reconcile poundforce w/slug and lbmass with Like.
The definition I gave based on SI units is indeed the definition of the pound-force used by NASA's manned lunar missions in the late...

By the time I went to high school seven or eight years later the science classes were teaching nothing but MKS (or cgs). Like @Mister T...

PeroK reacted to weirdoguy's post in the thread I Physicists disagree wildly on what quantum mechanics says about real… with Like.
And what is your basis for that claim? Have you studied physics? I mean like 5 years of hard work at Uni, or something equivalent? Or...

PeroK reacted to flyusx's post in the thread Confusion In Writing Identical Particle Wavefunctions with Like.
I had read up on identical particles and their associated symmetric/antisymmetric wavefunctions a while back and solved a few problems...
-
PeroK replied to the thread I Physicists disagree wildly on what quantum mechanics says about real….You have to if you study mathematics or modern physics. Although your main target is QM, the general theory of relativity entails...

PeroK reacted to syed's post in the thread I Physicists disagree wildly on what quantum mechanics says about real… with
Skeptical.
Again, this just isn't describing the issue correctly and is a common misunderstanding. You literally cannot even test QM's truth...
