Cool series for lay people

So this professor of physics at Cal Tech was bored and made a bunch of elementary lectures on core ideas in physics. It's designed without many mathematical prerequisites in mind, perhaps an understanding of calculus, differential equations, and linear algebra would be beneficial. It's called "The Biggest Ideas in the Universe". I haven't bothered to watch them in detail, but I skipped through some of them, and I thought it was very nice how he builds up and describes more advanced notions in a simple way.

Any of u fuks who are interested in learning more should check this out.

These aren't aimed to be serious course level lectures -- more like informal talks that give you a roadmap to understand the main ideas.
