So, this is a piece I'm working on with a large chorus of youngsters ages 10-12. I've never seen a tempo alteration spelled this way. Is it something distinct from "ritard?" Is it simply an unfortunate typo? It appears in Randall Thompson's "Some One," which is part of the larger set Two Chil...

I'm currently finishing my attic and I am wondering what insulation I should use in the ceiling. I was planning on using R38 or higher in the vertical and horizontal sections but in the angled sections I don't have a lot of room. They are 2x8s and after the baffles there is only 5 1/2 inches of...

As someone trying to learn electronics, I found the following diagram where there are these two electrolytic capacitors (470uF). Could someone explain the use of these components? How does the number/size 470 get chosen? Is their inclusion meeting a particular requirement?

If you saw a transaction from a UTXO you control in the mempool that you didn't sign (i.e. it was stolen), could you use RBF to move it to an address you control before it was confirmed?

I'm trying to prove that the following relation holds $$ \sum_{j=0}^n \binom{n}{j}(-1)^j F_j = -F_n $$ Where $F_i$ denotes the $i$-th finonacci number. I'm currently trying an induction argument but I get stuck at $$ \sum_{j=0}^n \binom{n}{j}(-1)^j F_j = (-1)^n F_n + \sum_{j=0}^{n-1} \binom{n}{j}...

I had this question in an interview a few weeks back and I haven't been able to stop thinking about it since.

I'm in the process of programming a space game which will involve a 3-body system.

It's known (but quite nontrivial) that $V=L$ implies that if $\kappa$ is the 1st inaccessible cardinal then there are $\kappa$-Suslin trees $T$. Such a tree $T$ can be considered as a forcing notion in $L$. Being Suslin, $T$ does not collapse $\kappa$. QUESTION. Can such $T$ be defined so that th...

Tungsten is a very dense and robust metal that has the highest melting point and boiling point of any metal. This makes it very resilient in certain situations but also makes it hard to craft stuff with in a forge. Let's say that in 1300 AD, every kingdom gains access to a magic wand. This wand c...

The look-say sequence is a sequence of lists of numbers where each element is the previous element with run length encoding. Run length encoding is the process of grouping together like elements and then giving the element and the size of the group for each group. So for example: 1 1 1 2 2 1 T...

I was a kiddo when I last saw this, but it was a ranchy high school comedy (like late 2000s early 2010s?). The two protagonist were teenagers (unpopular) the main one was a skinny nerd robot.

Etymoline hyphenates rock-bottom and provides a rather vague origin as a synonym of bedrock: "lowest possible," 1884, from the noun phrase meaning "bedrock" (1815), also figurative, from rock (n.1) + bottom (n.). What I would like to know is how this phrase came to be. Every time I hear it, I a...

If someone has a fly speed of 60 feet and moves 60 feet downward and then chooses to stop flying, they would descend another 500 feet totalling 560 feet in a single round. Is this correct interpretation of Xanathar's falling rules (page 77)?

An unbounded sequence $a_n$ can have a convergent subsequence for example $a_n = n$ if $n$ is odd and $a_n = 1/n$ if $n$ is even. What if it is unbounded and $|a_{n+1} - a_n| \to 0$? Can I conclude that it has no convergent subsequences?

Is there a single word to denote non-animated movies? What I have in mind is like the following: Disney is okay, but I prefer ??? movies. It should mean movies where human actors/actresses play, instead of cartoons or polygons. It has nothing to do with fantasy elements and Harry Potter is a ??...

I found these phrases reading and didn't get if they were a verb form, conjugation or what, I neither could find them on a dictionary. I assume they are colloquial forms of speaking and this is the context of each one: あんた学校どうする？念のため休んどいてもいいけど 何か違うんだろうか 考えんのやめよ

Elements on the periodic table are ascribed unique Chinese characters, and because they're relatively new characters (vs. thousands of years of history of the Chinese language), they're usually carefully designed and easy to remember. For example, the alkali metals are: 锂 (lǐ) Li (lithium) 钠 (nà...

The question sounds similar to Angle of rotation around arbitrary axis from matrix but it is not. I don't want an angle-axis extraction, from a 3×3 rotation matrix ${\rm R}$.

I am vaguely aware of laws regarding cash withdrawals for DI's in the U.S., namely that banks can place hold on transactions over $10k for up to two weeks, and that "structuring" isn't allowed.

Currently Twitter is being acquired by Elon Musk . As now the deal is likely to go ahead. What happens to the seller of Call options ( suppose some one has sold call for $60 strike expiring in June 2023), or seller of PUT options ( like someone sold PUT of $30 Strike for expiring in June 2023).

Consider a polynomial in one variable $p(x)$ with $p(0)>0$, and that is not a polynomial in $x^m$ for any $m>1$ (that is, the $gcd$ of the exponents appearing in $p(x)$ is 1).

Do the books in Wayward Children have to be read in release order or can you read any one of them first?

Let $f : \mathbb{R^n}\mapsto \mathbb{R^n}$ a smooth function. Can we give a condition for the application $F=I+f$, where $I$ is the identity, to be surjective ? I know that if the operator norm of the differential of $f$ is small, $\vert Df\vert <= 1/2$, say, then $F$ is a submersion, but it does...

I'm brand new to the world of belt-drive bikes so trying to understand what's normal and googling isn't helping with this specific question. One of the selling points of belt drives is low maintenance and less stretch than a chain. However, after just a couple of days and only 10km my belt is fee...

How would I get a shape like in image attached? Bascally a heaxagon with a cylinder merged but with the curve of the cylinder perfectly tangential to the two edges it is in contact with on the hexagon? Coming from a SolidWorks background so maybe trying to be too exact!

I have the following schematic. This is a NE555 with voltage controlled by a 12 V voltage reference (TL431) providing a PWM of around 10 kHz at a 90 % duty cycle. The PWM then powers the gate of an NMOS (IRFZ44N), allowing current to pass through it. This is my simulated circuit: This is my simu...

I only have experience with mainland Chinese families having 3 character names, however, my family only has 2 characters in our names. I saw a similar question acknowledging the difference between Hong Kong (3 characters) and mainland China (2 characters), but in my experience i've only seen main...

I am from Vietnam and my Schengen visa duration is 5 days. My flight itinerary is as follow: 3/11: 19:00 - 21:15 : Hanoi - Saigon. 3/11-4/11: 23:05 - 6:55 : Saigon - Paris. 4/11: 10:05 - 11:15 : Paris - Switzerland. My question is that when does my duration start counting. Is it 3/11 when I leave...

Whitebox labs makes "Electrically Isolated EZO™ Carrier Boards" which are isolated boards for Atlas Scientific sensors such as pH. I don't understand how can you get an isolated board if they are only using one power supply the same one as the Raspberry Pi or Arduino. Is an opto coupler really ne...
