@MoreAnonymous her old post does have some decent resources, but they're a bit dated
like I know the $\frac\eta s=\frac{\hbar}{4\pi k_B}(1+a\lambda^{-3/2})$ bound, but I'm looking for something more modern

I would like to know if there are, in the literature, articles or thought experiments about chirality/optical activity (I mean the Wikipedia Chirality) of bodies falling into a black holes. Many thanks all users.

It's interesting how so much of our culture revolves around reproductionary desire. Evolution has made sure to carve out the right circuits that encourage reproduction. Romantic love is in movies, books, and is said to be this magical, sacred, unexplainable thing.
How would the world look if humans were hermaphrodites. All movies and culture will be centered around this important moment of your life where you'll self-fertilize and it'll all be incentivizes with circuits like sexual reproduction currently is.

Q: Answer deleted when posted to duplicate question

PeterI came across the question Why does the melting point of water decreases with increase in pressure? and answered it. I found a day later that an earlier, almost identical question had been asked by the same author, so I improved my answer and submitted it as an answer to the earlier question. Tha...

Hi, everybody.
 
hello, Dr Sank

Hi Daniel Sank!
 
When finding E die to a straight wire through Coulomb’s law we need to resolve the dE into components. Let’s suppose a wire is sitting along x axis. We need to find at P. Which component will be cos and sin. Horizontal vs vertical.
I always thought it’s the x axis along which we take cos component.
Can anyone help!

@cOnnectOrTR12 It's not clear to me what you're asking. Why would the components be 'cos' or 'sin' to begin with? What angle is in play here? Why would it always "be the x-axis" along which you have a cos - doesn't that clearly depend on the situation you're considering?
 
Suppose a perpendicular bisector is placed at which we need to find the E. we select two elements on wire, draw dE due to elements which make 45 degree with x axis
Now charge is positive. The two dE are pointing away. Now here we have to resolve. Tell me which will be sin and cos
 
6:07 PM
I have read reference angle is measured from x axis.

Did a mod resign or something?
Surprised to see a new election so soon
 
@SirCumference you don't look at featured meta posts, do you? :P DZ resigned a while ago, and tpg recently, so we're back to the same amount of mods as before the last election.
 
8:10 PM
I see
Forgot DZ resigned, I think it was almost a year ago
