I run a YouTube channel called

Learn Maths Free, in which I upload various Khan Academy-style videos, of varying length, on a variety of mathematical topics, ranging from elementary (e.g.

Simplifying Basic Expressions), to slightly more involved (e.g.

solving definite integrals using contour integration).

My newest ongoing project is a playlist called

Geometry and Groups, a series which begins with a discussion of the Platonic solids and exhibits some of the beautiful links between group theory and geometry, and hopefully (eventually) climaxes with a discussion of the modular group, PSL(2,Z).

I'm very open to requests: many of my more recent videos were created as a result of being asked to do videos on those topics, such as complex numbers and surds.

All content is entirely free (it is all hosted on YouTube, after all). I hope you find this useful in some way.

(I'm not sure if this was posted in the right place. In which case, I'd appreciate if it were moved to wherever is deemed more appropriate.)
