I have another all-female species in my world, and it's Lamia; women from the waist up, snake from the waist down. Sort of like mermaids, but more commonly encountered by humans, as they live in forests, deserts, swamps, grasslands, and even caves (each environment has its own subspecies.) Lamia ...

$A$ and $B$ start running simultaneously towards each other from the two ends of a track $XY$ and the ratio of their speeds is $3$ : $4$. Every time they meet, they interchange their speeds and also reverse their directions. At how many distinct points on the track do they meet each other, if th...

I am sure this was due to my own ignorance on proper technique, but immediately after landing in a Cessna 172, I applied brakes and some moderate aerodynamic braking and experienced an awful and violent rapid shake of the plane. I let off the brakes but the plane continued to shake for a few seco...

I am tutoring a multivariable calculus student, and his teacher was solving $$\int_R f(x, y) dA$$ using the Change of Variable Theorem, where $f$ is an unimportant function and $R$ is the region bounded by $$\begin{align*} x^2-y^2 &= -1\\ x^2 - y^2 &= 1\\ x+y &= 1\\ x+y &= 3 \end{align*}$$ The he...

I'm studying lagrangian mechanics, and there's a property where you could obtain an equivalent lagrangian $\mathcal{L'}$ from $\mathcal{L}$ by adding a function which satisfies: $$ \mathcal{L'}\rightarrow \mathcal{L}+\frac{df(q,t)}{dt}.$$ This lagrangian $L'$ would give rise to the same equations...

In this example of a model for a piezo element, there is an inductive component: As the piezo vibrates, there are two forms of energy storage going on... capacitive, and inductive (or something like inductive). I believe that the inductive component comes from the piezoelectric effect, which rel...

I planning to write a long report (~300 pages) in latex. My report will contain a lot of Bangla text along with English text. I found several ways to write Bangla in latex, but I failed to choose the best way. Another important thing is that when I use Bangla setting as main font, it changes the ...

I have been writing a book for the last eight months ( at the moment I have already written 174 pages ) about anatomically plausible superhumans (a new kind of person who would have to surpass us both intellectually and physically, being smarter and stronger than ordinary people).

I am aiming to draw a square with circles - starting in the bottom left corner of the square the radius and the position of the subsequent circles (of course multiplied by the respective loop variable to move it one step further in each step) is the length of one side of the square divided by the...

I, and one of other players in my play-by-chat group, have expressed a desire to improve the narration of our character's actions. When they brought this up, I noticed the sort of unvaried descriptions I'd been giving as well: Fin hurries to keep up. Fin walks into the room slowly, looks aroun...

Discrete Time Signal Processing by Oppenheim says that for the product of two DFTs (i.e. circular convolution) to be equal to linear convolution, the DFTs must be at least P + L - 1 long where P and L are the lengths of the time domain sequences used to compute the DFTs. I understand this to mean...

Is it true that in the category of connected smooth manifolds equipped with a compatible field structure (all six operations are smooth) there are only two objects (up to isomorphism) - $\mathbb{R}$ and $\mathbb{C}$?

I'm living in Austria at the moment. I keep hearing people saying something that sounds like "Da die so". I mistook it for "daddys home" the first few times I heard it. I've also heard "da ma so".

In this video, YouTube: Did Ancient Romans Use Tattoos? @ 4:35, the presenter mentions a "Taxes Paid" tattoo.

As the books call it, Elrond's house is the Last Homely House east of the Sea. But if Rivindell is the last homely house, what are the other homely houses east of the sea?

I'm looking at this battery: SLB08115L1401CV I was under the impression that the chemistry of a lithium ion cell dictates the charged/discharged voltage levels.

I had a very bad PhD experience which has led to complete loss of motivation to pursue a career in theoretical physics.

$GL(n,\mathbb{R})$ can be seen as $\mathbb{R}^{n^2}$ with points of non invertible matrix removed which form "holes" in $\mathbb{R}^{n^2}$. These holes seems to be dense in $\mathbb{R}^{n^2}$ which will mean any neighbourhood of $GL(n,\mathbb{R})$ will contain holes, even for the neighbourhood th...

My understanding is that the extra cartridge RAM banks at &A000-&BFFF are battery-backed SRAM that is preserved after powering off the game. If I'm making a simple game that doesn't have a save feature, can this RAM be used as the home for the stack pointer? Putting the stack at the top of high r...

As I understand it, a basic chord is built of 3 notes, which can be harmonized in different octaves. It's always the first, third, and fifth to make up a basic chord. An extended chord then adds a note. A 9th extended chord, for example, adds the 9th note in the scale to the chord. So I would ass...

According to Catholicism, if a Christian lacks devotion to Mary and the Saints, is he or she spiritually "handicapped" or "missing out" spiritually?

The symmetric group $S_n$ - the group of permutations of an $n$-set - plays a very important role in Group Theory. The paramount importance of this group resides in the following fact: given any finite group $G$, there is a value of n such that $S_n$ possesses a subgroup that is structurally id...

Deepl says "I have got to stop pitying myself" is given by « Je dois arrêter de m'apitoyer sur moi-même ». The reflexive on apitoyer makes the moi-même seem redundant to me and the translation of to pity myself seems a bit convoluted here. Is Deepl's way the best way to express this sentence?

Consider $u,v\in \mathbb{R}^2$ where $u=(2,1), v=(-1, 2)$. $u$ and $v$ are orthogonal since $u\cdot v=0$. If we put them in $\mathbb{C}$, they should be still orthogonal. However, $ \langle u,v \rangle=(2+i)(-1-2i)\ne 0$. I must misunderstand something here. Could anyone explain this? Thanks in a...
