Math and physics help on the web

[dad-and-adam]

Hi all,
When reading some recent posts, I noticed questions regarding gaining an understanding of some math and physics
(trigonometry and projectile motion).
A collage professor by the name of Salmon Khan, has a website containing videos that explain these topics. He has over 1800 videos in a variety of math and science topics. I've watched a number of his videos and must say they are an excellent means to gain understanding. The math videos start at the most basic of topics and progress all the way though differential equations.
The website is: http://www.khanacademy.org/

Happy learning,
Dave

The best way to learn some physics, IMHO, is to go jump off cliffs. (Just think, if you survive, you'll be one of the greatest physicists that ever lived! You don't think Einstein knew what the effects of flying in a spaceship at near-light-speeds were by just sitting there and thinking?)

Muntoo, who has the audacity to compare himself with Einstein?
(BTW: As far as I know he actually was sitting very comfortable in that Swiss patent office when he was thinking about his Theory of Relativity...)

That's what they* want you to think.

*they being the patent office guys; who wants such a boring job? Only Einstein-wannabes.

muntoo, I don't know if you are serious -
Einstein was sitting from 1901-1909 in the patent office in Bern (Switzerland), and during that time he wrote both his dissertation ("A New Determination of Molecular Dimensions" which he applied at the University of Zürich) and several publications in a magazine, particularly one of them (1905) which was called "About a heuristic viewpoint concerning generation, and transformation of light" for which explicitly he was awarded the Nobel Prize for Physics 1921.

During 1901-1909 he was definetely neither flying in spaceships, nor was he reported jumping off cliffs, and there is no single publication of any alien abduction of Einstein (actually only one alien abduction has been published and verified by different sources (!) - and IIRC, that was about one decade ago and the victim was a guy named John H. or so.)

I remember he also said something like, "get a shoemaker's job if you want to have time to think to make theories", or something... And no, I'm not joking. He REALLY was abducted (by my grandfather).
