I'm playing a homebrew race (thylean centaur, from the Odyssey of the Dragonlords module) that has the following ability: Quadrapedal Stride Climbing or maneuvering in tight spaces is considered difficult terrain for you. Since climbing (unless you have a climbing speed) means you move at half ...

I would like to apply a linear transformation to a tensor. My linear transformation is encoded by a matrix, for example M = Table[m[i, j], {i, 4}, {j, 4}] Take some vectors V = Table[v[i], {i, 4}] W = Table[w[i], {i, 4}] I apply the linear transformation to vectors with the dot operator M . V ...

What is the minimum (lowest) amount of Ada needed to stake? Could you have the delegation fee + 0.00001 Ada? Where is this referenced?

First of all, a note: This question is motivated by my friend, who is a physics PhD student (I'm a math PhD student) and arose when I was trying to explain to him what line bundles are. (I wanted to tell him that a wavefunction is really a global section of a complex line bundle.) I was using a t...

I'm playing through Mario's Super Picross currently and after nearly 200 puzzles this one finally has me stumped as to how it is intended to be solved. What is the next step to solving this? Notes: This is a "Mario" stage so the game penalizes mistakes and doesn't provide a mechanism for forwar...

I have to calculate the limits $$\lim_{x\rightarrow 0}\frac{\sin(x\sqrt{x})}{x}\;\;\;\text{and}\;\;\; \lim_{x\rightarrow0}\frac{\sin\sqrt{x}}{x}$$ without using L'Hôpital's Rule, and I can't see how. Calculating those derivatives would help me determine if the two functions $x\mapsto\sin\sqrt{x}$...

I think I read this in the last five years, but I also think it may have been a reread. It was a full-sized novel, I think, with a set of magicians (healers?) dealing with a deadly epidemic in their city that involved high fevers and eventual death. The bit I'm remembering is where they find the ...

Background The source-terminated reflected wave switching scheme is a familiar one. One just needs to add a source-series terminator, which added together with the driver's output impedance equals the line impedance.

However, it flips half of them in opposite direction if I applied the rotation. Does anybody know why...

In a circuit, we can approximate the poles of the transfer function by calculating the AC Resistance and Capacitance at every node. For every node we get a pole so a change of slope in the Bode plot by -20db/dec. Is there a similar way of approximating the zeroes of the transfer function, so we g...

Consider the following function (this function has $n$ dimensions): $f(x_1,...,x_n)=10n+\sum_{i=1}^n(x_i^2-10\cos(2\pi x_i));\quad -5.12\leq x_i\leq 5.12$, $\text{minimum at }f(0,...,0)=0$. Using basic trigonometry, we can see that no matter the value of $n$, this function will always have a mini...

Assume $ \Sigma $ is a partially ordered set with the $\subseteq $ relation. Assume $C \subseteq \Sigma$ is a chain.

Their grandparents would then bring them back home to France at the end o...

I'm trying to find the complex fourier coefficient of cos(ax) with $a \in \mathbb{Z}$ The formula is given by $$c_n = \frac{1}{2} \cdot \pi \int_{\pi}^\pi f(x) \cdot e^{-inx} \, dx $$ I know that I can write cos(ax) as $$\frac{e^{iax} - e^{-iax}}{2}$$ This gives me $$c_n = \frac{1}{2} \cdot \pi \...

I've a m1 macbook pro 14" and a LG 27UK670-B display connected via USB-C to the mac. Connecting via USB-C leads to the macbook charging it's battery (taking power from the display).

Whenever I have solved circuits (only cells, resistors and wires), it has only been necessary to use Ohm's law (or things derived from Ohm's law, such as how two resistors $R_1$ and $R_2$ have effective resistance $R_1+R_2$ as a whole) and Kirchoff's loop rules. However, I was curious as to wheth...

Imagine a planet that sustains life, has oceans and continents plus an earth-like atmosphere; a planet similar to earth in most ways, but with only extremely dry and extremely wet biomes.

From the Monster Manual, it isn't clear to me whether the Doppelganger's shapeshifting ability is just that they are able to cast a successful Polymorph spell automatically, and therefore it's subject to the duration of that spell, or if they can remain in whatever form they choose for as long as...

I used Gaussian Elimination to calculate $$\det\begin{pmatrix}1&4&9&16&25&36\\4&9&16&25&36&49\\9&16&25&36&49&64\\16&25&36&49&64&81\\25&36&49&64&81&100\\36&49&64&81&100&121\end{pmatrix}$$ and found the answer to be $0$. It took a lot of time to do. The lower-upper (LU) decomposition is shown below...
