I'm drafting a text about music theory and, when looking for a way to describe the progress of steps between a note's octaves, the expression "looping spectrum" came to mind.

Suppose that $y=x^2$. Very often people describe this relationship by saying that '$y$ is a function of $x$'.

Suppose that $A$ is a well-ordered set. We can find $a_{0} = \min{A}$. Then, if $A \setminus \left\{a_{0}\right\} \neq \emptyset$, we can find $a_{1} = \min{\left(A \setminus \left\{a_{0}\right\}\right)}$, etc. Intuitively, this seems to be a counting process. Then my hypothesis is, every well-or...

I want to backup and sync my dotfiles using github. Since all the dotfiles resides in $home by default, should I just git init in my $home folder, or is that a bad idea? Having performed git init in $home, my idea is then to .gitignore all non-dotfiles and non-dotfolders.

If a circuit is linear, then you can use Thevenin equivalence to prove that if a port of a circuit has an open-circuit voltage of 0 V (the two terminals are at the same potential), then the resistor will not draw any current.

In short, I understand that Shapiro-Wilk "is good for small data sets" and with large da...

If $a,b,c\in R$ and, $$\left(\frac{a-b}{a+b}\right)\left(\frac{b-c}{b+c}\right)\left(\frac{c-a}{c+a}\right)=-27$$ Evaluate $$\frac{b}{a+b}+\frac{c}{b+c}+\frac{a}{c+a}$$ I noticed that you can reduce the question to the following: If $(1-2x)(1-2y)(1-2z)=-27$, then evaluate $x+y+z$ where $x=\frac{...

As far as i understand it, total differentials are linear maps that map vectors to numbers. In thermodynamics we encounter statements that a we have reached equilibrium when a total differential of a certain function is zero. For example equilibrium is reached when the Helmholtz free energy funct...

This manga had everyone born with an animal spirit. Those who get strong ones become important and powerful. The main character get a "boring" cat and goes to a school to train the guardians. Turns out his cat was a legendary tiger hiding.

Does the Fathomless' Tentacle deal extra damage from the Spirit Shroud spell as it is you doing the attack via the tentacle? If so does the target have to be within 10 feet of both the warlock and the tentacle? Tentacle of the Deeps: As a bonus action, you create a 10-foot-long tentacle at a po...

Suppose you have painted a landscape with mountains and villages in the background, and you decide to put (lake) water at the bottom. Now you need to reflect the landscape into the water. The only solution I can think of, apart, obviously, from painting everything again upside down, is to copy th...

I am currently reading the book "universe in a nutshell". I reached the point where Einsteins Equivalence principle is explained. It states, that you can't distinguish if your in a space shuttle that moves at constant acceleration or if you are in a parking space shuttle in a gravitational force ...

The reason for asking, is that this occurs in real life with CRT calculation of RSA decryption/signing. In CRT RSA, there's the need to calculate subtraction, and it's known negative numbers could occur, especially with multi-prime cases. While RSA would eventually phase out when moderately-sized...

I recently ordered a monstera plant online and the seller mentioned that the plants they send out shouldn't need to be repotted for ~6 months, but when mine arrived, it looked to be root-bound in the pot, with a large root growing out the bottom of one of the nursery pot draingage holes: When I ...

I'm trying to learn some quantum mechanics by myself, and because of my mathematics background, I'm trying to understand it in a rigorous way. Since then, I've been intrigued by the use of rigged Hilbert spaces in this context. The topic caught my attention one more time after my discussion on ph...

Let's assume we have a $n \times n$ grid repeated periodically, and I want to create some random isolated patches on it (and assign some value to those grid points). For a simple example consider this - a grid of RandomPolygon a = 4; l = 3; d = 0.1; w = a*l; polys = Flatten[ Table[RandomPolygon["...

I wonder whether OP_DEPTH 0 OP_EQUAL has the exact same behavior as OP_DEPTH OP_NOT which is 1 if no items 0 if any number of items I'm asking because the first script is used and I'm not sure if there is any justification for that. It's very likely that they took the simple approach but I nee...

Is there some simple method for determining if a DOS (or OS/2, or Windows etc.) binary (.exe or .dll) is 16-bit or 32-bit? The Linux file command just says "executable". I want to distinguish between programs that run on any "x86" processor, and those that "require a 386", in a way that is simple...

Define a = RandomReal[1., {2, 100, 100, 100}]; then Total[a, Infinity]; // RepeatedTiming {0.00183727, Null} and Total[a[[1]], Infinity]; // RepeatedTiming {0.00879665, Null} Why? half work takes much more time?

I am currently trying to get the display By doing this code, i was able to produce \begin{gather} 1 \uparrow 1 = {}^1 1 = 1 \nonumber \\ 2 \uparrow \uparrow 2 = {}^2 2 = 4 \nonumber \\ 3 \uparrow \uparrow \uparrow 3 = {}^{{}^{{}^3}} {}^3 3 = 3 \uparrow \uparrow 3 \uparrow \uparrow 3 = \...

I am reading this article here that explains why bitcoin is a better store of value than gold. If someday this "bitcoin standard" does come to fruition, would it be susceptible to the problems that plagued the gold standard?

So I'm new to logic and im getting really confused on definitions namely that of universal and existential quantifiers and why vacuous truths only apply to statements with a universal quantifier $(\forall)$ and not for existential quantifier $(\exists)$. I read that the 2 statements (1) $\forall ...

I have many text files in a directory. I want to append/add * at the end of last line (content) of each and every text file of the directory with the extension .txt How can this be achieved in Ubuntu 20.10 in single operation? Why I am asking this is because currently I am working on .txt and .pg...

I've heard quite a few stories of Big Sur bricking older MacBooks, but I'm not quite sure in which way precisely they get bricked (motherboard or just SSD), so question is whether the following story fits into those reports: I have the 13" MBPR (Early 2015, 2.9 GHz i5) of my 78 year old father he...

I want to change the default_frames_limit in the movie clip editor. I found a script in a addon that does exactlie that: clip = bpy.context.edit_movieclip clip.tracking.tracks.data.settings.default_frames_limit = 10 But it just works from within the movie clip editor, not from a text editor scri...

Problem of the day, that pesky Starship Hoverslam. Imagining a crazy (childish) contest to see who could flip at the lowest altitude and brake to 0 rate of descent and land, it was (hilariously) imagined one could "cheat" by braking in the horizontal with "side rockets" then flipping and landing....

This accessory is included with every Nintendo Switch that ships. But we never know what to call it. Usually in our household we'll be like "can you pass me the grip thingy that the controllers dock into for single-player mode?" That's getting a bit tiresome. Sure, we could give it our own name ("...

In "Drow of the Underdark", p. 90, there is an NPC with the special ability "burning faerie fire". Where do I find the rules on this ability?
