I have to take my hat off to Sal Kahn for a truly immense resource. What he has achieved with the Kahn Academy is nothing short of incredible.

He’s single handedly generated 1000+  instructional videos covering subjects including:

• Economics
• Finance
• Chemistry
• Arithmetic
• Pre-algebra
• Algebra
• Geometry
• Biology
• Trigonometry
• Precalculus
• Statistics
• Probability
• Calculus
• Differential Equations
• History
• Linear Algebra
• Physics

What a wealth of information. This has to be place in the category alongside Academic Earth and Udemy.

This site, Sixty Symbols, does for Physics and Astronomy what my last post, Periodic Table, did for Chemistry.

Well these are (just a little bit) famous. The Chemistry dept. in Nottingham explaining the Periodic Table in separate videos.

The videos are hosted on their YouTube channel.

And there’s a dedicated site.

I came across these videos when I was looking out how a trebuchet works (as I mentioned previously). These are a series of videos on YouTube presented by “Steve Jones an experienced mathematics and science teacher”. As you can see from the screenshot they cover nuclear energy, Richter scale, electricity generators, and a few others.
