One teacher told me that the bare infinitive cannot be used as the direct object of a modal verb because it is not a noun. But, isn't infinitives with or without "to" infinitives?

In my math textbook there's an example problem where you're asked to calculate $$\lim _{x \rightarrow 1}\left(x^{\frac{1}{1-x}}\right)$$ It says that the limit is of the form $1^{\infty}$ and that it can be transformed and solved using L'Hopital's rule. The limit of $x$ is $1$, but the limit of $...

In official tournaments, are the two players allowed to talk (before or at the start) of a match to compromise on openings, eg.

Let me explain my deal. We can split any positive number into addends, and then we can take those addends and use them now as factors. The product will be maximum if all addends were equal. E.g. the number 10 can be split apart as 9 + 1, or 8 + 2... Many ways. However, if we split it as 5 + 5, th...

By now, it's been clarified by Sage that the Harengon trait "Bunny Hop" is a bonus action that doesn't consume movement, and that it gains the bonuses of the spell "Jump".

Newer ARM processors apparently only support 64-bit code. The Play Store has stopped showing 32-bit only apps to 64-bit capable devices. Will Android become a 64-bit only operating system as time passes?

Assume that a face of a mesh is defined by vertices A, B, C and that the normal of the face is defined by (B - A) x (C - A). Rotating the mesh about its local origin with matrix R makes the normal calculation R(B - A) x R(C - A). To my knowledge there is no algebraic property of the cross product...

Deciding whom you choose as your friends says as much about you as it does them. (From a test) I'm thinking if the sentence is missing a word: Deciding whom you choose as your friends says as much about you as it does about them. I think this preposition is indispensable.

The story has to do with the last man left alive at the end of civilization. His name was Galen Garr or Galen Gann or something to that effect. He has the power to raise the dead, but he finds "the city of the undead to be worse and more full of madness than the city of the living" (my recollec...

A textbook I'm using to refresh some basic grammar states that indirect objects can be identified by it's answering of questions such as 'to whom', 'to what' etc. (fair enough) and they always come before direct objects in a sentence (this raises questions for me).

It may have been an alien-built installation or spaceship. I just remember that it was fantastically dangerous inside. I don't remember where I read this story, but it was probably in an anthology.

I've been reading the SEP about Nothingness and it gives a good summary of the philosophy around "Why is there something rather than nothing?". One of the confusions it notes is that "nothing" is ambiguous. It could mean a perfect void, the physicist's "vacuum", or actual non-existence. The artic...

Let $A=\bigcap_{t\in T}D_t$ be an integral domain such that $D_t$ is a commutative factorial domain for every $t\in T$. It is quite natural to see that $A$ is a completely integrally closed domain. Moreover if we assume that $T$ is finite, $A$ is also a Krull domain. My question is, do you know w...

Let $(M,g)$ be a complete Riemannian manifold with Laplacian $\Delta:C^{\infty}_{c}(M)\to C^{\infty}_{c}(M)$ (think of $\mathbb{R}^{d}$ if you wish). This operator is essentially self-adjoint in $L^{2}(M)$ and hence, its closure $\overline{\Delta}:\mathcal{D}(\overline{\Delta})\to L^{2}(M)$ is se...

This is a relay circuit I am using. I got the PCBs and the relay is not switching. After debugging, I noticed that one terminal of the relay is not going to 0V while the other is 5V. It stops at 2.5V or near that. Any ideas on how I might be able to fix this issue? Note: I have not populated R48...

I am reading the definition of a localizing subcategory $\mathcal{D}$ of a triangulated category $\mathcal{C}$ (Definition 1.1.1 of the book Axiomatic Stable Homotopy Theory). It refers to a 'cofiber sequence' $$X\to Y\to Z\to\Sigma X$$ in $\mathcal{C}$. Does this mean the same as an exact/distin...

On a recent exam, in an integer-type question in Chemistry, I calculated my final answer to be 10^0.6, I thought I had calculated the answer incorrectly as there was no way that would be the answer. I just left it since there were no calculators allowed. Turns out, putting it into a calculator la...

If a variable point $P$ moves such that the line passing through $P$ and $Q(0,0,2)$ makes an angle $60^{\circ}$ with the $z$-axis then find the locus of $P$. Also find the locus of intersection of locus of $P$ with the plane $x+y+z=1$. The first part of the problem is pretty easy. The locus I...

Having recently started to read Dungeon Crawler Carl (highly recommended, btw!), I've been reminded of a series I read a few decades back. As is often the case, my memory is a bit fuzzy. But the basic gist was that there were a bunch of humans (and possibly an android?) in a spaceship, who were ...

As sets, we can consider the space $C(\mathbf{R}^n;\mathbf{R}^k)$ - of all continuous functions from $\mathbf{R}^n$ to $\mathbf{R}^k$ - to be a subset of the product space $(\mathbf{R}^k)^{\mathbf{R}^n}$ (because the latter is the set of all functions from $\mathbf{R}^n$ to $\mathbf{R}^k$) Take $...

Consider all the integers from 1-13. Without reusing any integers, find a set of three integers for which all numbers 1-13 may be created using only addition and subtraction. Prove that for all such sets, it is not possible to create a sum of 14. For this question, I've identified that 1,3,9 is a...

lately I lost access to SPSS and instead of using Python or R, I tend to perform analysis using a free software called Jamovi. The thing is, this software doesn't have the different non-linear regression models I liked to use in SPSS, so I tend to make only linear-regression models. Because of th...

$\newcommand{\sset}{\mathsf{sSet}}\newcommand{\poset}{\mathsf{Poset}}\newcommand{\p}{\mathscr{P}^{\mathsf{nd}}}\newcommand{\N}{\mathcal{N}}\newcommand{\sd}{\operatorname{sd}}$Following this paper, I encountered two different subdivision functors on $\sset$, and while there is a clear mathematical...

I'm trying to teach myself the classical differential geometry of 2D surfaces in 3D Euclidean space but I'm struggling to understand exactly how much information the Gaussian and mean curvature provide. If I've understood the Bonnet theorem correctly, the Gauss–Codazzi equations are both necessar...

Have recently migrated from SQL 2016 where the DB's compatibility level was all set to 2008 to SQL 2019 where the compatibility level for all DB's are now 150. Upon running workload for a while, I found some queries that weren't performing too well. I added the hint OPTION (USE HINT ('FORCE_LEGAC...

I need suggestions/ideas of optimizing the following query: SELECT COUNT(*) FROM (SELECT 1 FROM f WHERE parent_sha256 = $1 AND parent_sha256 <> sha256 LIMIT 1) AS row_count; Which is needed to verify if a specific parent_sha256 has any direct childs. The table is v...

You work at a beach. In the afternoon, the sun gets quite hot and beachgoers want to be shaded. So you put out umbrellas. When you put out umbrellas you want to shade the entire beach, with as few umbrellas as possible. Umbrellas come in many sizes. However, larger umbrellas are susceptible to be...

Edit: Thanks for helping! I have been looking for this story on and off for like 8 years! This was a story I found online it was short to mid length. The story is told from the perspective of a woman. She has a relationship with a man that is involved in technological development and they talk ab...

I am not sure so I'll ask just in case. Let $X$ be a scheme and $\mathcal F$ a sheaf of modules on $X$ which is globally generated by $\{s_i\}$. Do these sections also generate $\Gamma(X,\mathcal F)$ as a module ? Is it true if we suppose that there are finitely many generators, or more ? In fact...

Introduction The inquiry into the nature of values isn't merely theoretical; it is a matter of existential importance, especially when the values you've grown up with have been rooted in deception, manipulation, and emotional abuse. From Distorted Values to Self-Discovery Inherited from a childho...

I was listening to Coffee Break French audio, season 4 episode 18. Near the beginning the commentator says he has only a few days left until his holidays start. There is some phrase used like ''je jis moins jours'' or ''j'ai J moins jours''(something like that). I would love to know.Thanks

I have a small shed that is off-grid and needs occasional lighting. During the day I can open up the doors and have sufficient light, but during the winter when I am out there more in the evening, I need occasional light. Ideally I would like to have 4x 4ft LED shop lights hung from the ceiling. ...

I have these set of equations. The number of equations depends on $n,$ which I want to keep control of. The code that I have generates it using Table and equations generated by this does not take an input. I want to generate same equations as functions. n = 5; h = 1/n; x[0] = 0; x[n] = 1; xs = T...

I have long wondered whether its possible (in theory at least) for jetliners under typical loading scenarios (pax and cargo), landing at a normal airport such as LHR to come to a slow enough speed to exit the runway just by using spoilers, full flaps and normal friction (air and tyres) i.e. no br...

I'm trying to understand how tokens and expansion work in the context of the following problem. I'd like to create a tblr environment from the tabularray package via a command that does some of the formatting programmatically. Unfortunately, the tblr environment does not like this. A minimal work...

Hi I feel like this is an obvious question but I haven't been able to get a good answer so far. Given the name of the service (which I know running on localhost) is there any networking command line tool like (netstat/ss) which will tell me what port that service is running at? Ideally something ...

This blockade was imposed shortly after Hamas' perpetration of large scale atrocities, killing 1300 Israelis, mostly civilians, on October 7th. However, maintaining a blockade also seems to be running against the Geneva Conventions (which Israel is not a signatory to). Question about asked here...

Emmet is a text-editor and IDE plugin for writing HTML code using much fewer keypresses. You might think of it like a code-golfing HTML preprocessor. Its syntax is based on CSS selectors. Your challenge is to code-golf an implementation of Emmet. Given some Emmet code, output the resulting HTML. ...
