Khan Academy

Khan Academy is a collection of over 1,400 miniature lectures, delivered by one man via YouTube. They cover topics that range widely, in disciplines including mathematics, chemistry, biology, statistics, history, finance, and physics.

From the twenty or so I have tried, they seem to be quite accessible, at least for those with a basic grounding in mathematics. I had never covered matrices in high school or university math, but the videos in the linear algebra collection have left me with what feels like an adequate theoretical awareness of what they are, why they are useful, and how they fit into mathematics more broadly.

The whole collection is worth a look.

Khan academy also has several sets of videos related to current economic matters:

Credit Crisis

Geithner Plan

Paulson Bailout

I don’t know what sort of ideological or economic assumptions they make.
