#### Customer Reviews

##### Fantastic resource

Incredibly helpful for my AP Physics class. The professor doesn't just give you formulas and show you how to use them, he goes into a lot of depth showing how the formulas are derived and why they work. He is very clear but concise, may be too fast for some but that's why you can pause, rewind the video.

##### Amazing!!!

So so so helpful!! My uni has pod casts too but this guy is great. He doesnt just expect everyone to know what's going on. Also I love that he writes with chalk!

##### A Great Resource

I'm currently in an undergrad physics class, and these lectures are excellent for learning the background of the topics. Prof Shankar is a really good teacher; I don't know what I would have done in physics without his simplified, gradual explanation of these sometimes complex subjects.

He tends to focus more on the derivation of the formulas and the reasoning behind the laws, which might frustrate someone looking to take a more applied approach, but I suppose he figures that anyone can apply the formulas, the hard part is figuring out where they came from.

All in all, I would definitely recommend this to any student who wants to actually understand physics.
