weirdoguy replied to the thread Undergrad Particle vs Wave Interpretations of QM.If there exists some deeper common framework one can ask the same question: what is it that allows this deeper common framework to exist... -

Like.
To put it more rigorously, if two bodies are wholly or partly in rolling contact then at each instant a point on one body that is in... -

I don't know if it's cultural, but here in Australia I know of nobody who complains about paying taxes (we are a very high tax-paying... -

Cup half full cup half empty. People who complain about taxes as a matter of principle should be aware what life in very low tax... -
weirdoguy replied to the thread High School Can anyone deeply understand relativity?.Well, I read one book on history of QM (Duncan, part 1) and I don't know how non physicist could understand any of it. -
weirdoguy reacted to Dale's post in the thread High School Can anyone deeply understand relativity? with
Agree.
My “aha moment” came when I drew my first spacetime diagram complete with coordinate lines for both frames via the Lorentz transform... -

My problem with Cox is that during any talk he gives you can pretty much count on him turning to the audience and confidently... -

Like.
The fields could be the fundamental entities. They wouldn't be made of anything else. Why is it a problem to have many fields in the... -

Like.
Your parents might not be so happy, though... -
weirdoguy reacted to FactChecker's post in the thread High School Why simplifying this function generates different outputs for same input? with
Like.
Correct simplification includes keeping track of where the original function was undefined. -
weirdoguy reacted to XuYi8888's post in the thread Graduate Does a Particle's Identity Have a Physical Cost? with
Sad.
My question is: Does maintaining a particle's intrinsic identity require a continuous, irreducible physical cost? I have been thinking... -
weirdoguy reacted to Mike_bb's post in the thread Undergrad Homogeneity of space and time in Landau & Lifshitz with
Sad.
In other source "homogeneity of space and time" means homogeneity of space and homogeneity of time. Not a spacetime. -
weirdoguy reacted to hokhani's post in the thread Undergrad Momentum measurement and uncertainty with
Skeptical.
To resolve this problem, Born-Von-Karman boundary conditions is used. -
weirdoguy reacted to PeterDonis's post in the thread Undergrad Momentum measurement and uncertainty with
Skeptical.
"Uncertainty" as in the uncertainty principle is not even about the variance of a large number of measurements of a single observable...
