FactChecker replied to the thread Undergrad Please Explain (actually explain) The Monty Hall Problem.Really? So knowing that he may have intentionally avoided that one door doesn't clue you in and change the odds? What if it started... -

Like.
It is relevant because it changes the conditional probabilities and the amount of information received. There is still some information... -
FactChecker replied to the thread Undergrad Please Explain (actually explain) The Monty Hall Problem.This is the point that is often missed. Suppose Monte Hall just blindly opened one of the remaining two doors and it happened to have a...

That argument fits the Monty Hall game, as generally understood. But, there are alternative ways to play where that argument fails...

FactChecker reacted to Hornbein's post in the thread Graduate What Exactly Is The Physical Content Of Maxwell's Equations? with Like.
A nice thing about geometric algebra is that there is no such thing as "the right hand rule." The sign comes about naturally. An...

FactChecker replied to the thread Graduate What Exactly Is The Physical Content Of Maxwell's Equations?.I don't think their criticisms address what appealed to me about geometric algebra. I liked that it started with a basic geometrical...

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...

Love.
What also may help for understanding the EM field is to use Geometric Algebra, applied to 4D-spacetime. The wedge product ##\wedge##... -

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...

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
