Simple problem: spacing in math mode can often be awkward, especially with large fences and super- or sub- scripts. Usually, this amounts to exponents being too far from the parenthesized expression, like in the 2nd last example, where it is closer to the enclosing parenthesis than the inner expr...

Without getting into unrealistic scenarios, I ask myself the following question: would electronic lines and the equipment connected to them be safe if a large CME occurred, say, between 2am and 3am? It would seem logical that a r...

I'm trying to update Craft to 4.5.10 which requires PHP 8.0.2+ but I have Feed Me plugin installed, which is using Cakephp 3.10.5, which requires PHP >=5.6.0,<8.0.0. Is it possible to update Craft to 4.5.10 without removing FeedMe plugin? Thanks

The two-part TV episode Human Nature/The Family of Blood was originally a Virgin New Adventures book, also called Human Nature. The TV story ends with this brutal scene (taken from a transcript): Does this scene happen in the original book? I couldn't find it.

I have read in philosophical literature that in the old days, many philosophers used to equate necessity with always existing. Nowadays, it seems that something eternal can be seen as contingent (I.e. could have not existed) and something that doesn’t always exist can be seen as necessary. For ex...

I know that this may come off as an incredibly dumb question, but please hear me out for a while. Why don't objects just tug at other bodies with a constant force? Instead, why do they apply different forces depending on the masses of the bodies in consideration, so as to keep the acceleration p...

It was an old American movie where a doctor believes his wife has an alien baby growing inside her belly, and in the end he insists on doing surgery on her (by opening her torso) to find this alien baby. The scene is very depressing and in the end the woman dies, but it remains unclear if there a...

I performed a deep clean on my Epson XP-640 printer (forcing cleaner through the heads, with a paper towel under the heads), and when I was done I replaced the ink cartridges. When I turned the unit on again, it gave me an error message that "The printer is exposed to strong light". Google return...

So, the problem is about solving the following statement through induction: $$\frac{1}{n+1}\sum_{i=1}^n \left(\frac{1}{n} + i^2(i-1)!\right) = n!, n \in\mathbb{N}^+$$ What I've done so far: Beginning (for $n=1$): $$\frac{1}{2}(1+1)=1=1!$$ (shortened it for the question) Induction Step: Show $\fra...

In my program Chemcraft, a popular tool is the “Set point group” utility: it symmetrizes the molecule according to a specified point group, and then the symmetry of the molecule is correctly recognized by a program like Gaussian, and this makes the computation faster. Maybe chemists dealing with ...

We resolved an issue caused by a broken access point by simply disconnecting it from the LAN. The symptoms we experienced were that now and then, our whole network would get "stuck" for a few seconds. That meant that during web calls, the sound and video would shortly freeze, then continue normal...

In this video from Kurzgesagt they said that one would need to disassemble a whole planet to build a Dyson swarm around the sun. The video went on about mining Mercury and using the materials available on it. If one wanted to mine Mercury in the future, I bet many people would be upset about it, ...

An odd issue arose with my dryer outlet, and I am more concerned than initially. Below are the chain of events: Dryer: Samsung dryer spun, but did not heat Replaced heating element Plugged in, did not power on Troubleshooting dryer, thought it was the circuit panel Purchased new dryer Plug...

Mathematica nicely solves Poisson's equation in spherical coordinates as eqn=Laplacian[V[r,\[Theta]],{r,\[Theta],\[Phi]},"Spherical"]==-Sin[\[Theta]]; a=1;b=10; sol=NDSolveValue[{eqn,V[a,\[Theta]]==1,V[b,\[Theta]]==0},V,{r,a,b},{\[Theta],0,\[Pi]}]; but failed to solve a similar time-dependent pr...

Given two natural numbers (less than 100) as input print the sequence of intermediate results obtained when computing the sum of the two numbers using only the following operations1: n <-> (m+1) for integers nand m satisfying that equation (a+b)+c <-> a+(b+c) for integers a,b and c (associative ...

I'm developing a project that runs upon a private Tangle, deployed locally on my PC. After some updates on the Wiki IOTA website (https://wiki.iota.org/), I can't find the relative documentation describing how to install and run a private Tangle anymore. Where can I find it? Thanks.

To add Arrow connecting the red point across two Show[] function result as below, Could I know how to modify my code? trialSet = {1, 4, 5}; sampleMean = Mean[trialSet]; Column[ {NumberLinePlot[{trialSet, Style[sampleMean, Red]}, {x, -6, 6}, Spacings -> 0], Show[Histogram[{sampleMean}, Plot...

Europa, one of Jupiter's moons, is 4.5 billion years old (like Earth.) However, its surface is only 20-180 million years old. What could lead to a planet/moon's surface being younger than the planet/moon itself?

The Issue Getting a hum in audio recording (ACX) When I move the mic around in the room it gets stronger or weaker in certain areas (where I know a power cable runs to a plug or through the wall) I can hear it when monitoring and when listening to the recording but only after doing the amplificat...

Are there any Jewish sources (halachic) that explicitly discuss political activism, or being involved with secular governments. The older and more primary the source(s), the better.

I am translating a video game into German and I am sometimes unsure whether someone should be using "du" or "Sie." I have heard that "du" is normally used to indicate familiarity, i.e. with family and friends, but can also be used in insults, where it indicates not familiarity but lack of respect...
