According to my understanding of General Relativity, gravity is not a force and an observer which is falling freely under the influence of gravity should be considered inertial. Now, I have come across some texts about black holes that say a body approaching black hole will be eventually ripped i...

The trend of using the last part of words, bot for robot or za for pizza for instance, appears to be from the late ‘60s as suggested by Etymonline: The method of minting new slang by clipping the heads off words does not seem to be old or widespread in English. Examples (za from pizza, zels...

I have a gravel bike with the following 1X set up: FSA Omega Megaexo crank, 40T; Sunrace 11-46 CSMS8 cassette; Sram Apex1 11 spd derailleur; Sram Apex 11 speed Double-Tap shifter. I would like to change the cassette to an 11-51 but I don't think my derailleur can handle it. It is only rated for 4...

I'm pretty deep into the game, relying on quickhacks for damage so far, and I've yet to encounter enemies immune to quickhacks entirely. This seems to indicate that I don't need any other weapon. However, I notice many of the quickhack build guides (e.g. this) take Reflexes for a second option. B...

I know if it's \$ \Sigma \$ we put 1's in the Karnaugh map, but I don't know what \$ d \$ is. $$ f(a,b,c,d) = \Sigma m(0,1,4,10,15) + d(7,14) $$ From what I've googled, https://en.wikipedia.org/wiki/Karnaugh_map it seems to be a "don't care", but I'm not so sure, because this is the first time I'...

If the alpha is set to 0.05 I have encountered many scientific publications saying that a "tendency for an effect" is present based on a p-value of 0.05 < p-value <0.1. On the other hand, I have had statisticians who criticize me for doing so, because there is only "reject" or "not reject". There...

This is a paperback novel that I read in the 00s, but I am fairly certain that it was published earlier (probably circa 1970s).

Let $X_1, X_2, X_3, X_4$ be independent and identically distributed continuous random variables. Then we know that for any $s,t$ real numbers $$P(X_1\leq s, X_2\leq t)=P(X_1\leq s)P(X_2\leq t)$$. Then, can I claim that $P(X_1\leq X_3, X_2\leq X_3)=P(X_1\leq X_3)P(X_2\leq X_3)$? If this is true,...

This question is about a step in the proof of this answer, which is not directly clear to me. Consider the following scenario: $H$ is a Hilbert space, $A\in GL(H)$ a positive self-adjoint operator. We surround the spectrum $\sigma(A)$ by a contour $\gamma$ which does not intersect $]-\infty, 0]$....

The question is as in the title. I have browsed online (Wikipedia, etc) and while they do give me the definition, it gets a bit too much physics-y for me.

The upper-bound is easy to get since $\min(i, n-i)\leq i$ for $i\in\{0, \dots n\}$ so that $$\frac{1}{2^n}\sum_{i=0}^n\binom{n...
