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.

In the spring of 2005, I graduated from the University of British Columbia with a degree in International Relations and a general focus in the area of environmental politics. In the fall of 2005, I began reading for an M.Phil in IR at Wadham College, Oxford. Outside school, I am very interested in photography, writing, and the outdoors. I am writing this blog to keep in touch with friends and family around the world, provide a more personal view of graduate student life in Oxford, and pass on some lessons I've learned here.
