Whenever there is an entropy, it can be defined as S = - sum_n p_n log( p_n ) where the p_n is a probability distribution: for n = 1...W, p_n >= 0 and sum_n p_n = 1. This is always the underlying equation, the only thing that changes i

That quote is not from the article? And in any case, the fine does not seem to be about the blue checkmarks at all.

The New Yorker article from 2023 about this saga is worth a read: https://www.newyorker.com/magazine/2023/10/09/they-studied-d... Technical details of the fraud can be found in four famous-ish blog posts

Did you notice that you are replying to a top-level post which accuses the twice elected president of the USA of acting against American interests? "Having a democratic mandate" is either a valid counterargument or it is not. But

So far only one of these two ideas sounded not entirely deranged to the good people of YC. So there is at least (and, perhaps, also at most) a sociological difference.

> there's a chance neutrinos are Majorana particles. Pet peeve: don't say "are Majorana particles", say "have a Majorana mass term". All spin 1/2 fermions in four spacetime dimensions can be constructed

Impressive, but after reading the title I have to admit to being a little disappointed at not finding 10,000 solutions.

If X1...Xn are independently uniformly distributed between 0 and 1 then: P(max(X1 ... Xn) < x) = P(X1 < x and X2 < x ... and Xn < x) = P(X1 < x) P(X2 < x) ... P(Xn < x) = x^n Also, P(X^{1/n} < x) = P(X < x^n)

I just want to convey the following point: for the vast, vast majority of physicists the status of MOND is akin to what doctors think of the anti-vaccine theories. The evidence in the opposite direction is simply overwhelming. You refer to

by prof-dr-ir 2y ago
The trouble is that MOND is just not worth your time. In fact, I would even object to calling it a 'theory' in the first place. MOND is just some wild idea, but a little thought should convince every physicist of its uselessness.

Very nice explanation by Matt Strassler. I am not sure it is possible to do better without getting into the details of quantum field theory. For those who know quantum mechanics I would add that the oscillations mentioned in the article ar

The more you know, the more fun the book is. At times the going is tough even if you are a physics professor, because Pais accurately captures the process of discovery which was often messy with unfamiliar equations, strange logical jumps,

In the end tensor fields are sections of a bundle. I insist that calling them "just functions" is simplistic. In fact, I'd say that the complexity of your elaborations kind of proves my point. Note that I deliberately use &qu

First of all, in some sense it is not that interesting of a statement. Whether gravity is a force or not, or whether light is a particle or a wave -- all that depends on definitions of the word force, particle, wave, etc. And nowadays tha
