I want to apply Lighting to some ListPlot3Ds with Texture applied, but it's not taking as it does with Plot3D. As an example, p[x_, y_] := PDF[MultinormalDistribution[{25, 25}, {{25, -12.5}, {-12.5, 25}}], {x, y}]; (* too dark *) Plot3D[p[x, y], {x, 0, 50}, {y, 0, 50}, PlotPoints -> 50, PlotS...

In the prime MCU universe, the one in the same universe as the movies, what level of knowledge does the general population of Earth have about the snap/Blip. For example, do they know that it was caused by an alien warlord using mystical artifacts from the dawn of time, and that the Avengers trav...

Suppose we have a standard regression model and want to identify whether we have violated the assumptions of the model. Traditionally, we might utilize a significance test to determine whether (for example) the residuals are normally distributed (where the null model states that the residuals bel...

I am working on an exploration which starts with the following affirmation: In this section you studied the Binomial theorem. Recall function composition from earlier in the course. In this context (in working with a function under the operation of a composition) when we raise a function to a po...

It feels like the concept of a "developing market" but a developing market implies a foreign market but 下沉市场 is a part of domestic market.

$\mathcal{C}$ denote the cantor middle third set. $$\mathcal{C}_t=\{(1-t)x+ty : x, y\in \mathcal{C} \}$$ $\mathcal{C}_0=\mathcal{C}_1=\mathcal{C}$ and we can prove that that $\mathcal{C}$ contains no non empty open interval. What can be said for other $t\in [0, 1]$? Does it contains a non empty o...

The artificer's Infuse Item feature (TCoE, p. 9; E:RftLW, p. 57) grants access to a number of infusion options, one of which is the Homunculus Servant (TCoE, p. 21; E:RftLW, p. 62). I'm just trying to find out whether the Homunculus Servant I create has, for example, tool proficiencies to help me...

TL-DR: How to create a world with ecology similar to ours, that doesn't have such abominable plagues of mosquitoes in its Arctic summer? It is tempting to think of mosquitoes as a pest of the tropics, and they certainly are as far as that goes. But as far as I can tell, the worst mosquito plagues...

So I am trying to solve two equations simultaneously. The goal is to find values for $\frac{de}{dt}$ and $\frac{d}{dt}$ which are the rates of change of the variables $a$ and $e$. I am then progressing the system through time by multiplying the rates by a certain time step and adding this to the ...

I love tuna so this question has been bugging me senselessly. I am aware that larger fish tend to have more mercury concentration in their flesh than their prey, however, I don't understand how this can be possible. I understand that there will be more mercury in the large fish than the small fis...

A high school classmate of mine was approached 5 years ago by a lesbian couple to father a child with one of them. They did not involve lawyers at the time.

My daughter, an adult UK citizen/passport holder, has been accepted for a 1 month ballet "summer intensive" at a US Ballet Academy, and it runs from 3rd July in Orlando, Florida. Some people are telling me a student visa might be needed (M-1) because she might be classified as learning. Others...

Let $f(x) = \sum\limits_{(n,m)\in\mathbb{Z}^2} \frac{1}{(x+ n + i m )^2}$ If feel it should be $1/E(x)$ where $E$ is some elliptic function, like $sn^2$.

$\def\ZZ{\mathbb{Z}}$Call a function $f : \ZZ \to \ZZ$ "contracting" if $$|f(j) - f(i)| \leq |j-i|$$ for all $i$, $j \in \ZZ$. The contracting functions form a monoid under composition; call it $C$. An element of a monoid is called a "unit" if it is invertible; the units of $C$ are the functions ...

BIP342 defines OP_CHECKSIGADD as a replacement for OP_CHECKMULTISIG.

I need to make a run from my detached garage to my house. The run exits the garage by way of an LB, runs underground for 25ft in 1 1/4" Schedule 40, then enters the house through another LB.

This was a science fiction short story about the captain of a ship that sails from port to port on an alien planet. I'm not sure whether the captain is a human or the native alien species, and if he is a human whether it is the case that the planet was colonized or it's supposed to be some kind o...

In general relativity, if a volume of particles moves unrestricted through spacetime, is their volume always conserved? Say we let a collection of particles at rest wrt each other, fall freely in a gravitational field. Will tidal forces keep the volume they occupy constant? My intuition says yes,...

I was reading this question and was reminded of another story with a virtual or augmented reality nursery. It might be a short story in a collection or it might be just a sub-plot of a novel.

When I consider a proof, such as Euclid's proof of the infinitude of primes, it can give a sense that something necessarily true has been obtained. I cannot remember where I got the idea, but a few years ago I encountered a notion that dispelled this feeling. It is not a complicated notion. All I...

As I understand, we usually talk about gravity at a macro scale, with "objects" and their "centre(s) of mass". However, since gravity is a property of mass generally (at least under the classical interpretation), it should therefore apply to individual mass-carrying particles as well. Has this ev...

I think there is no doubt that the science in the science fiction of Star Trek in the 1960s was far superior to that found in any competing show.

The remainder theorem stated that " If a polynominal f(x) is divided by (x-k), the remainder is f(k)." So I think of a constant function ,say, f(x)= 5 and I divide this by (x-1).
