Like.
A really great book that integrates it with multivariable calculus and linear algebra is... -
FactChecker replied to the thread Graduate What Exactly Is The Physical Content Of Maxwell's Equations?.Can you recommend a reference for this approach? I have limited knowledge of differential geometry and (at my age) consider myself only...

FactChecker replied to the thread Graduate What Exactly Is The Physical Content Of Maxwell's Equations?.IMHO, as a casual amateur, geometric algebra (and geometric calculus) goes a long way to demystifying the subject. Unfortunately, it...

FactChecker reacted to Sagittarius A-Star's post in the thread Graduate What Exactly Is The Physical Content Of Maxwell's Equations? with
Love.
What also may help for understanding the EM field is to use Geometric Algebra, applied to 4D-spacetime. The wedge product ##\wedge##... -

Informative.
if it is static website (with no backend) then host it in github or tiinyhost. if it has backend and you have like a laptop which is... -
FactChecker reacted to renormalize's post in the thread Undergrad How do bar detectors work in gravitational wave detectors? with Informative.
Yes, and I think that's exactly what @Ibix is talking about as well. To quote his post #4, with some clarifications in brackets added by...

FactChecker reacted to Ibix's post in the thread Undergrad How do bar detectors work in gravitational wave detectors? with Informative.
As @renormalize says, I know that. Interferometric detectors like LIGO have mirrors that are free to move independently, so they don't...

I think our guy is talking about Weber Bars. A precursor to LIGO, without lasers. https://en.wikipedia.org/wiki/Weber_bar

FactChecker replied to the thread Generative AI Success.The Feynman fake videos are like the Matrix movies, where you can sometimes see a "glitch in the Matrix" that looks unnatural. But that...

FactChecker reacted to PeroK's post in the thread Undergrad Please Explain (actually explain) The Monty Hall Problem with Like.
This is the critical assumption/characteristic of the game. First, Monty's pick is not random (he never reveals the car); and second...

FactChecker replied to the thread Undergrad Please Explain (actually explain) The Monty Hall Problem.That's a good way to look at it. Your original door still has 1/3 chance of winning. That leaves 1-1/3 = 2/3 chance and only one door...

Right ##-## if you always switch, then whenever you first pick the prize door (1/3 of the turns), you lose (by switching from the...

FactChecker replied to the thread Undergrad Please Explain (actually explain) The Monty Hall Problem.What you learn from that is this: Your door was not opened because he is not allowed to open your door. You knew that already. The other...

FactChecker replied to the thread Undergrad Please Explain (actually explain) The Monty Hall Problem.If I understand what you are saying, this is wrong. You are gaining no advantage from knowing that Monte Hall (might have) intentionally...
