Poster for Math Awareness Month 2014, celebrating the centennial of Martin Gardner’s birth.

Pi in its full glory, popping up in all kinds of formulas.

Which one do you find the most beautiful or intriguing?

I like its appearance in the values of various integral-defined functions: Gamma(1/2), the integral of exp(-x^2) over R (which is related to the error function), and the integral of sin(x)/x over R (which is the limit of the sine integral Si(x), and I didn’t know before today!).

A properly, conformally embedded once-punctured torus in R^3, parametrized by

1/(1-sin(u)sin(v))*(cos(u)cos(v),cos(u)sin(v),sin(u)sin(v))

with 1≤u≤2π, 1≤v≤2π, obvs.

(A surface in R^3 is *properly embedded* if its intersection with any compact set is compact. Thus, the puncture in this surface is placed “at infinity”. A surface is *conformally embedded* if angles in the intrinsic metric match angles in the ambient metric. Here, you can see that latitude and longitude lines on the torus meet orthogonally.)

The definition of the college lecture is a mechanism of moving information from the notes of the professor to the notes of the student without it moving through the minds of either.

The Julia set of 2*cos(z) on the complex plane. I was inspired to make this by this post.

chaotic-renan replied to your post:If you’re still looking for stuff to do, I think a 4D Sierpinski sponge would be pretty neat to render.How the heck does that work?Well, first you think of one of these, but one dimensions up. Then, you conceive of a way to spin it around. Then, you intersect it with an appropriate hyperplane. Finally, you express this thought to a machine capable of generating an image from it. With your help, it should be able to produce something like this.

I would pay money to see slices of a 4d Menger sponge.

Five great mathematicians and their contributions, in minimalist posters – the best thing since those minimalist posters celebrating pioneering women in science and philosophy’s major movements distilled in minimalist graphics.

A nanocentury is about Pi seconds long.

Useful.

While it would be more accurate to say “the first eight digits of π” rather than “the value of π”, it’s hard to be too upset with a post that merges math and coffee.
