haushofer reacted to Demystifier's post in the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture with
Like.
I don't know whether Coleman's position contains something original, but there is something else that I find problematic. Coleman first... -
haushofer replied to the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture.It's comparable to the time where the geocentric and heliocentric models both successfully explained planetary orbits. It was only in...

haushofer replied to the thread Advice on visiting CERN?.My advice: don't mention the war or supersymmetry.

haushofer reacted to Ibix's post in the thread High School Infinite universe, infinite volume from the beginning? with Like.
Not misleading, just wrong. You are correct that if the universe is closed and finite then it always was; if it is flat or open and...

haushofer replied to the thread Undergrad ##r-##independent angular momentum in quantum mechanics.Intuitively: if r and v point in the same or opposite direction, L is zero. So only movement in the direction perpendicular to r...

haushofer reacted to DrClaude's post in the thread Undergrad Finite potential well transmission coefficient with Like.
No, it applies to scattering states. I think this is pretty clear in the text you posted. When E>0, you will always get transmission...

I ended up here looking for an answer to a question and am extremely grateful for the prompt and informative answer. I'm neither...

haushofer reacted to Heinera's post in the thread Graduate The de Broglie wavelength: What happens in the case of a frame change? with Like.
Try this one: Robert Shuler: "Common Pedagogical Issues with De Broglie Waves: Moving Double Slits, Composite Mass, and Clock...

haushofer replied to the thread Undergrad 2nd order ODE's, variation of parameters and the notorious constraint.Yes, that's a gread addition. It leaves me with the final question: are all constraints one can impose consistent? And how can we check...

haushofer reacted to wfro64's post in the thread Software Engineer with interest in quantum simulations with Like.
Hi everyone, I’m Werner from Switzerland. My background is in software engineering, but I’ve been studying quantum mechanics and...

haushofer reacted to pasmith's post in the thread Undergrad 2nd order ODE's, variation of parameters and the notorious constraint with Like.
Thinking about it more closely, we want ##c_1y_1 + c_2y_2## to be a particular solution. But we're happy if it's only determined up to a...

haushofer replied to the thread Undergrad 2nd order ODE's, variation of parameters and the notorious constraint.Yes, thanks a lot, you're absolutely right. Reading your post I redid the calculation and indeed was missing a factor of p(x) which...

haushofer reacted to pasmith's post in the thread Undergrad 2nd order ODE's, variation of parameters and the notorious constraint with Like.
I think you have an error in the algebra. Substituting the ansatz and condition into the ODE, we should find $$\begin{split}...

haushofer posted the thread Undergrad 2nd order ODE's, variation of parameters and the notorious constraint in Differential Equations.Hi folks, I decided to brush up my knowledge of Green's functions and Differential Equations, and came across this chapter...
