Khan Academy:
On a mission to educate the world (for free)

by Eric Drexler on 2009/12/28

I got a pointer to a free, online educational resource today.

It deserves more attention.

The eyeballs of a few million students might be a good start. Students in elementary school, grad school, rural Africa… places like that.

It consists of 1000+ brief lectures on YouTube.

It centers on math, but goes beyond.

Here are a few samples that illustrate of the range of content:



Basic Addition
Level 2 Addition
Partial Derivatives
Partial Derivatives 2
Gradient 1
Gradient of a scalar field
Introduction to the Convolution
The Convolution and the Laplace Transform
Using the Convolution Theorem to Solve an Initial Value Problem


Thermodynamics (part 1)
Thermodynamics (part 2)
Thermodynamics (part 3)
Thermodynamics (part 4)
Thermodynamics (part 5)


Mortgage-Backed Securities I
Mortgage-backed securities II
Mortgage-backed securities III


Glycolysis
Krebs / Citric Acid Cycle
Electron Transport Chain
Oxidative Phosphorylation and Chemiosmosis



There’s a FAQ:

A lot of my own educational experience was spent frustrated with how information was conveyed in textbooks and lectures. There would be connections in the subject matter that standard curricula would ignore despite the fact that they make the content easier to understand, enjoy, and RETAIN….These videos are my expression of how the concepts should have been expressed in the first place, all while not compromising rigor or comprehensiveness.

I’m impressed. Reviews are welcome.

Mr. Khan has created a truly amazing resource for people to supplement their education. I am going back through and tuning up my math skills with his lessons, and I am finding that doing so is improving the foundations quite nicely. I wish I had access to this resource when I was attending high school and college. It is very inspirational to see this available to anyone able to get online and understand English. Hopefully someday the site will grow large enough to add translations into many different languages so more and more people will be able to educate themselves. Thank you for sharing this, Dr. Drexler.
