Apart from math, I also do chemistry stuff from time to time. Considering that this was what I have a degree for, it's perhaps surprising I don't do it often.

I haven't posted here in a while, but I do have a Ko-Fi now, if you're interested in the stuff I make or I have made: ko-fi.com/B0B110V17

Also did something on rolling squares, if you prefer something less advanced: shadertoy.com/view/3tXGzS

I'm well aware I have been quiet in quite a while. In the meantime, here's a domain coloring plot of the Weierstrass ℘ function written in GLSL, and demo'd on Shadertoy: shadertoy.com/view/WtXGzs

On matters of notation: sometimes your convenience is my confusion.

As I get older, I've increasingly found myself in the situation where I find some write-up on the Internet that I think to be nifty, and then find to my surprise that it was actually written by my younger fool self.

Rhombitrihexagonal tiling conformally mapped to a torus.

An animation of successive approximations to the prime-counting function $$\pi(x)$$ using zeroes of the Riemann zeta function $$\zeta(s)$$. See doi.org/10.1090/S0025-5718-197 for further details.

...and a domain coloring plot of the zero-order first Hankel function, as once depicted in Jahnke and Emde (people.math.sfu.ca/~cbm/aands/).

Some more domain coloring stuff: here is a modern depiction of an altitude chart for the Faddeeva function, as depicted in Abramowitz and Stegun (people.math.sfu.ca/~cbm/aands/).

It is not very well-known that if you roll an ellipse on a congruent ellipse, the focus will trace out a circle.

...and one more before I leave the Internet café: a minimal surface constructed using Björling’s formula on a helix.

Some more old stuff of mine unreleased until now: a plot of the constant mean curvature surface called the Wente torus, with period quotient $$8/7$$.

Another one of my domain coloring stuff from my archives: an iterated rational function with icosahedral symmetry, plotted over the Riemann sphere

Elliptic functions really look lovely in domain coloring plots. I made this one to have a triple pole and a triple zero.

One of my Perlin noise experiments on polyhedra.

I hate it when popular articles, in their attempt to convey how big or small a number is, fully write out the number with all the zeroes it has, and thus forcing me to count zeroes to grok it. I hate that these writers assume (possibly rightly) that most people don't understand scientific notation, so that they have to do this. Saying things like "that's one followed by twenty zeroes" afterwards helps, but not much.

Here's some artwork that was a side product of research I was doing on orthogonal polynomials. This is related to this earlier release: community.wolfram.com/groups/-

Finally joined this thing, so here is an old image I did of the Boy surface
