Another nice mech problem
Can you tell which book is it from? Or maybe in which year it appeared on the olympiad (if it did).- weirdoguy

Undergrad Uncertainty and particle in a box
No, as is explicitly stated in wiki article: https://en.wikipedia.org/wiki/Particle_in_a_box#Momentum_wave_function And also was explicitly said in what you quoted :wink:- weirdoguy

Replacing "inertial" with "elastoid-inertial" in rotating systems
Yes, and based on that and ALL your posts and threads @Simon F , I don't really think you understand what they are talking about. You have some weird obsession about Coriolis, but nothing you cite agrees with what you are trying to say (or at least I think you are trying to say): that physicists...- weirdoguy

Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?
I don't even think that what you do with your experiments (with so many complexities and variables) is covered in any textbook. I am worried though that you think you're doing something against 'mainstream", because you don't, so: Because 99,99% of people who think they discovered something...- weirdoguy

Undergrad Why ##a^0=1##?
They do, as ##a^x## clearly shows. But you blindly run around the most simple problem with the most simple solution. -
Graduate Error in Landau-Lifshitz Vol 2, Fig. 20, page 310
Yeah, I had all of them because of that (I was not interested in all the topics that some of those volumes covered). But I sold most of the books that I didn't use, and I definitely didn't use any of LL books.- weirdoguy

Physics/math: how much knowledge does a high school teacher need?
It's free in Poland :oldbiggrin: But I didn't do those 'credentials', on purpose, so that I could not teach in normal school.- weirdoguy

Quantum Textbook Sequence Request: Entering B.Sc. Physics (Theoretical Focus)
Me too. I had it, sold it, and bought it again recently, so that I can solve problems from it (I didn't do it the first time).- weirdoguy

Undergrad Why ##a^0=1##?
What's the difference? Multiplication is commutative, you can write 1 wherever you want. My thought: you are overcomplicating things. -
Does the Lorentz factor aid understanding of SR, or obscure it?
And the answer is yes, whether you write gamma, or write square root explicitly. You can't avoid it.- weirdoguy

How? It's just a notation. Writing down this square root explicitly every single time is tiring. That's all to this. EDIT: You've had similar thread about this: https://www.physicsforums.com/threads/lorentz-factor-in-textbooks-on-special-relativity.1078774/- weirdoguy

Graduate Interference with slits of different width
Ok, I thought about it, but I felt that there is something more to that. Thanks! :oldbiggrin:- weirdoguy
