PeroK reacted to ojitojuntos's post in the thread I Question about discussions around quantum interpretations with
Like.
Thanks a lot for replying! I believe that the fact thanQM hasn’t provided a satisfactory explanation (in the sense that it is... -
PeroK reacted to Demystifier's post in the thread Book recommendation after Sakurai Modern Quantum Physics with Like.
Maybe Atkinson and Johnson, Exercises in Quantum Field Theory. It's like a textbook written completely in the form of completely solved...

PeroK reacted to planck999's post in the thread Book recommendation after Sakurai Modern Quantum Physics with
Wow.
TL;DR Summary: Book after Sakurai Modern Quantum Physics I am doing a comprehensive reading of sakurai and I have solved every problem... -
PeroK replied to the thread A Crisis in France -- Bottled water may not be what it's advertised to be.Or, you make rubbish beer, and tell people it's the best.

PeroK replied to the thread B Onto set mapping is the surjective set mapping, and into injective?.That's why i checked about the AC. Think about how awkward it is to get a bijection between ##\mathbb R## and ##\mathbb R^2##.
-
PeroK replied to the thread B Onto set mapping is the surjective set mapping, and into injective?.I suspect the proof is non trivial!
-
PeroK replied to the thread B Onto set mapping is the surjective set mapping, and into injective?.Does that work?
-
PeroK replied to the thread I Question about discussions around quantum interpretations.That is the issue. Many people, for whatever reasons, believe that the universe must be fundamentally deterministic. QM challenges that...

PeroK replied to the thread B Imaginary Pythagoras.I recommend correcting the thread title! I assumed someone would have done it by now.
-
PeroK replied to the thread B Effect of mass on the acceleration of an elastic pendulum?.Is this what you are looking for? https://en.m.wikipedia.org/wiki/Elastic_pendulum
-
PeroK replied to the thread B Onto set mapping is the surjective set mapping, and into injective?.I looked it up. The AC is not needed.

PeroK replied to the thread B Onto set mapping is the surjective set mapping, and into injective?.For example, ##X = Y = \mathbb R## and ##f = g## are both the exponential function. Then how to construct ##F##?

PeroK reacted to Ibix's post in the thread I Why measure the speed of light in one direction? with Like.
You can construct Maxwell's equations in non-orthogonal coordinates if you like. Then you'll get a non-isotropic speed. As always, this...

This made me laugh: Linux has been using SSH for decades with that same principle, securing practically all the servers of the...

PeroK replied to the thread B Imaginary Pythagoras.That's one representation of Minkowski geometry, where the vertical axis is time and the horizontal axis is spatial. The spacetime...
