Khan Academy

August 30, 2010 | Amateur Science, Links | By: Mark VandeWettering

I’ve seen the Khan Academy listed a couple of times before, but never really bothered to look at it again until today. I was confused about a minor issue in linear algebra (hey, it’s been 25 years since I took linear algebra) so I surfed over and found the lecture on null subspaces to be clear and easy to follow. The Khan Academy has a huge number of lectures, covering mathematics, economics, physics, and lots of other good stuff. Bookmark it for future reference!

Khan Academy.

I discovered Khan Academy yesterday and watched about eight videos last night. It’s wonderful; I plan on watching several a day until I see them all.

Bookmarked! But I’m gonna be real disappointed if these aren’t narrated by Ricardo Montalbán.
