Theoretically, each addition of a sound identical to the previous one results in a 6db increase in the final sound result. I ask: is that why in some orchestrations we see, for example, 6 clarinets playing the same passage in unison, that is, just to increase the final volume and highlight this ...

Consider an atom in the excited state radiating a photon and goes to the lower energy state. But photons have a certain angular momentum, the momentum itself is not defined. In this case, will there be a recoil of the atom due to photon emitted?

Would they have to wear a wig? Or is their condition obvious such that no one would suspect them of transgressi...

I mentioned to a Japanese chat friend that I liked music after he asked me what I liked. He then typed ほおほお. Does it mean something similar to I see?

Greetings from Switzerland, (I apologise for this poorly worded question) Is it possible to create a command "root" (e.g. \law, with a fixed structure as detailed below, never used in the document itself) and subsequently create other "subcommands" (e.g. \lawbueg, \lawbuev, \lawkbueg) depending...

If I just do it by writing that the sum on y axis is 0 I get $100+x=200$ $x=100$ If I try torque around the top: $x*800=200*500$ $x=125$ So what am I doing wrong?

As written, a Scout Rogue "can move up to half your speed as a reaction when an enemy ends its turn within 5 feet of you." What exactly constitutes when an enemy "ends its turn"? Does this mean the enemy gets to make their attack(s) before the Scout can use Skirmisher and move away?

I have a large modern fantasy Empire in my setting, and it focuses on the exploits of several students in a military academy. At some point in the story, however, a war breaks out and the academy becomes a focal point of a siege. For potential references in case this may help, the tech level of ...

I recently played a Lichess Bullet Game as White. [FEN ""] 1.e4 e5 2.h4 Nc6 3.d3 Nf6 4.g3 Bc5 5.Nc3 d6 6.a3 O-O 7.b4 Bxf2+ 8.Kxf2 Ng4+ 9.Ke1 a6 10.Bh3 Nd4 11.Bxg4 b5 12.Bxc8 Rxc8 13.Nge2 Nxe2 14.Qxe2 c5 15.bxc5 dxc5 16.Rb1 c4 17.dxc4 bxc4 18.Be3 h6 19.g4 f6 20.Bxh6 gxh6 21.Qe3 Kf7 22.Qxh6 Ke7 ...

There are ten wires that run underground across a river. Thus on each of the banks, there are ten ends of the wires. Unfortunately, given an end of a wire on this bank, one doesn't know which end on the other bank it corresponds to. Suppose that you an ohmmeter and a bunch of wires. (You can then...

Let's assume has a big problem and is dealing with it. While he has not solved the first problem, another problem comes up and adds to the previous one. I wonder how you would explain this situation through an idiom / an expression or even a proverb in current English? I know the expression: "do...

I am wondering if anyone knows of a way to separate the clear bottom piece from the brick on part# 7049b "Brick, Modified 2 x 4 with Wheels Holder Old and Trans-Clear Bottom" without breaking anything. Photo for reference: I have one that has a loose bottom and it got me wondering if they...

I recently started reading Filipovic's Consistency problems for HJM interest rate models and came across the Musiela reparametrization $$r_t(x)=f(t,x+t)$$ so the forward curve can be thought of as a map $x\to r_t(x)$. The book goes on to tell that this maybe thought of as an infinite dimensiona...

Let's say I trained an encoder-decoder network on cat dataset using reconstruction error as loss function. The network is fully trained and the decoder is able to reconstruct good cat images. Now what if I use the same network and input a dog image. Whether the network be able to reconstruct dog...

As a computational scientist, are there limitations to studying dynamical systems — systems of odes in which each state variable evolves with time — compared to studying PDEs? For instance, it seems that modeling blood flow in the heart is done with PDEs, but in some research papers for fluid-st...

In this article from Wikipedia, a war between the Pawnees on one side, and the Sioux and Cheyennes on the other side, is represented. It is claimed this war was a total war because the "non fighters" were targeted and killed. However I am wondering: is it the only experience of such a total war...

I am setting up a cold wallet. How can I generate a signed raw transaction from bitcoin core wallet that controls some bitcoins? PS: I generated the wallet using getnewaddress in console from the bitcoin-qt GUI

I have a database for example datatest (Length[datatest]=10) : datatest={ {52, 2, 5, 1, 5, 1, 15, 2, 13, 2, 2}, {1, 1, 2, 1, 1, 2, 2, 1, 2, 2, 1}, {2, 6, 4, 3, 8, 4, 2, 9, 4, 6, 5}, {0, 0, 0, 0, 1, 2, 2, 3, 2, 0, 83}, {, 6, 4, 6, 2, 12, 4, 8, 2, 12, 5}, {1, 1, 2, 2, 3, 3, 4, 41, 11, 12, 1}, ...

I'm building a magic system where magic isn't just controlled by human brains, but is actively produced there. As a byproduct, when casting a spell, the brain generates a large quantity of visible light (but not infrared light or heat). I don't know much anatomy, but I would imagine that, since h...
