Can someone please explain to me why those two identical planes behave differently? Plane 1 can be weightpainted, while Plane 0 can't. I appended those planes from an important project file I am working on and deleted all the vertex groups, modifiers, color attributes, geo-scatter system, etc. So...

I'm trying to calculate the HOMO of various molecules in water solution. I first tried to see how PySCF calculates the HOMO of hydrogen. I ran the following code: mol_h = pyscf.gto.M(atom = 'H 0 0 0', spin = 1, basis = 'ccpvdz') rks_h = mol_h.ROKS(xc = 'b3lyp') rks_h.kernel() rks_h.analyze(verbos...

What are examples for categories that admit all products but not all coproducts.

The title might have started "If you were a M*" I read this story about 2015 but it seemed to be written some decades earlier. A small number of human men are living on a planet inhabited by an intelligent alien race. After the humans arrive many of the alien children born look very like the indi...

I completed the first draft of my debut novel, now split into three books, and enlisted a developmental editor for refinement. I'm deliberating the ideal timing to involve beta readers in the process. One option is to engage beta readers before the developmental editing phase. I seek their compre...

Given a prime $p\equiv 1\pmod 4$, Fermat's two-squares theorem discovered by Girard states that there exists two integers $A,B$ such that $p=A^2+B^2$. For all primes up to $10^7$ the integers $A$ and $B$ are squares modulo $p$ if $p\equiv 1\pmod 8$ and they are fourth powers modulo $p$ if $p\equi...

What is the best way to get the symbols \coloneq, =, and \eqcolon (provided by package mathtools) to align in a nice way (so the equals part of each is aligned) in an align environment?

This is a question that I’ve been trying to wrap my head around that can be best illustrated as an example. SETI is a project that tries to monitor radio signals to detect extraterrestrial intelligence. It tries to detect certain sequences of prime numbers for example. If we did detect them, it m...

I found a strange issue when experimenting with dvisvgm trying to create SVG files from DVI files.

Consider an \$(n+1) \times (n+1) \$ grid of points places at non-negative integer coordinates. Given two points in the grid at \$(a, b)\$ and \$(c, d)\$, we know that the distance of the first point to the origin at \$(0, 0)\$ is \$x = \sqrt{a^2 + b^2}\$ and the distance of the second point to t...

I type some equations from text books into database, which later read from Mathematica to solve. Since I do this manually, sometimes I make mistakes where I type Exp(2*x) instead of Exp[2*x] or type Sin(2*x) instead of Sin[2*x] and so on. The problem is that when reading this code into Mathemati...

I was thinking about the trivial topology, in which the only open sets are $X$ and $\emptyset$, where $X$ is the entire space we are working in.
