This movie explores the connections between Rubik's cube and the group theory concepts behind music.

The butterfly map of the world is based on Reuleaux triangles. This article explores some of the story behind this interesting map.

Reuleaux triangles have a property similar to circles - they have constant diameter when rotated.

A 1×1 matrix is often regarded as a scalar quantity, but is that correct? This article explores a reader's question.

A quite remarkable new proof of the 400 year-old Wallis Product approximation for π has recently been published. It arises from a study of the quantum mechanics of a hydrogen atom.

Is there a difference between cube root and raising a number to the power 1/3? Maybe there is!

svgPHPGrapher produces clean math graphs with no javascript, and all the processing happens on the server.

When sketching mathematical functions on paper or computers, it's a good idea to have a sense of what the general shape of the curve is before you start. Sampling can lead to erroneous results.

YouTube engineers faced a problem as the number of views for Gangnam Style approached 2 billion. I found related issues when developing the Newton's Method graph.

I added a new interactive graph that helps explain how Newton's Method works. Newton's Method uses differentiation to solve non-linear equations and is especially useful when we can't factor the equation. It's very commonly used by computers when solving math-based problems.
