An animated introduction to the Fourier Transform, winding graphs around circles.

An algorithm for numerically solving certain 2d equations. Even though we described how winding numbers can be used to solve 2d equations at a high level, it's worth pointing out that there are a few details missing for if you wanted to...

Q&A #2 + Net Neutrality Nuance

A new and more circularly proof of a famous infinite product for pi.

Happy pi day! Did you know that in some of his notes, Euler used the symbol pi to represent 6.28..., before the more familiar 3.14... took off as a standard?

An ode to tau in sonnet form.

Intuitions for divergence and curl, and where they come up in physics.

A beautiful proof of why slicing a cone gives an ellipse.

A visual for derivatives which generalizes more nicely to topics beyond calculus.

Marcus du Sautoy delves into the fascinating world of mathematical codes and shows us how modern technology relies on them to let us communicate quickly, effectively and safely. In this programme, Marcus explains how everything from the...

The financial crisis that ran from 2007 to 2009 has been called a "Minsky Moment," meaning it offered a much-needed reminder to all economists of Hyman Minsky's neglected dictum that "capitalism is essentially a financial system."...
