Khanacademy.org: 1550+ vids: alg, calc, trig, phys, chem, stats, etc.

I came across this site while trying to find good math tutorials, and he is impressive! So far I've found the videos really helpful, which are each about 10 minutes each, good for e-attention spans.

khanacademy.org

Salman Khan (Sal) founded the Khan Academy with the goal of using technology to educate the world.

Sal received his MBA from Harvard Business School. He also holds a Masters in electrical engineering and computer science, a BS in electrical engineering and computer science, and a BS in mathematics from the Massachusetts Institute of Technology.

Iirc from an interview vid, he quit his job as a hedge fund analyst(?) and decided to put up a few vids for fun. They really caught on, and now he's up to 1200 so far.

Enjoy.

/edit: 1400 vids, he's done every one of them, altho others have been translating them various other languages (spanish).

/edit: There are also exercises for a relatively short list of subjects (algebra to trig) that appears he's currently developing.

/edit: from posting below:

I used this to get through Calculus I last semester (barely) and it was invaluable - way more helpful than my professor.

Geeeeez. Wonder what his a) student loan payments look like, or b) scholarship payments looked like?

bookmarked. Thanks. Kudos to the guy and the internet for making it possible.

I just checked out some of the videos on topics I vaguely remember from college. Pretty cool, very nice approach to the subject.

Yeah he is great. Been watching him when i need to review a bit on calc or DE.

Wish i had this when i took the calcs. Man they would have been so much easier lol.

I'm trying to learn some calculus. So far he's made it interesting, but we'll see how good he is or how bad I am.


updated: 1400 vids!

Also bookmarked...maybe he can teach me algebra...

I'm fine with "regular math," but as soon as you put letters and squiggly lines in an equation...it becomes "fuzzy math" for me.

I took algebra in high school and did ok, (too busy with "other things" to really pay much attentions) but that was over 40 years ago...I think they changed the numbers or something.

 

[I Saw OJ]

Saw this guy on the news a while ago and thought it was interesting. Glad the OP posted this, maybe I can find some stats homework help...

The tablet he uses for his lessons has been upgraded a few times since he began, so some are much prettier and better resolution than others.

Physics: Intro to Motion

Calculus: Derivatives 1

heard a story about this guy on The World, I think. sounds pretty cool.

You know, not the same thing at all, but MIT has a shit-load of free courses covering just about anything that you can download.

This guy has more degrees than the entire city of Detroit.

I tried looking at some of their material a year or two ago and it blew my head out of the water. I don't remember what I was looking at tho.

So far I find Khan's explanations refreshing...he's excellent at walking thru things in very simple terms with very understandable analogies. It's very unusual imo for a person this smart covering some advanced topics able to consistently speak in terms that 'less brain gifted people' oops can relate to.

I'd love to hear feedback from someone familiar with some of the more advance studies to see how they would rate his tutorials.

Checkout the MIT OpenCourseWare. They have a ton of free CS videos.

I already found all I need on Youtube.

:awe:


Seriously though, I'm 31 and I get bored in class. I wonder what its like for all the 18 year olds. Modern students do not seem to be faring well with old teaching. We really need newer, better systems for all education.

 

[yhelothar]

He's a good lecturer too. A lot of his lectures easily beats the ones I've had.

what does he use software and hardware wise to do this?

what does he use software and hardware wise to do this?

According to his Faq:

What equipment do you use to make your videos?

I use Camtasia Recorder ($200) + SmoothDraw3(Free) + a Wacom Bamboo Tablet ($80) on a PC. I used to use ScreenVideoRecorder($20) and Microsoft Paint (Free).

His Faq was last edited yesterday.

 

[TheVrolok]

I think I'll take a peak at the finance stuff.. This guy is great.

 

[zoiks]

Thanks OP. Bookmarked.

 

[GodlessAstronomer]

Hey cool he uses the same tablet as me

 

[Special K]

I think I'll take a peak at the finance stuff.. This guy is great.

His series on banking and the bailout are both very good.
