Physics

With a wink of humour in its own motto, Physics is a channel devoted entirely to physics: from everyday mechanics to relativity, quantum theory or astrophysics, explained with a genuine wish to be understood. It's for people who see the laws governing the universe as more than a high-school subject.

The student wanting to reinforce concepts gets a lot from it, as does the fan of popular science and anyone who has ever stared at the sky wondering how it all works. Physics, well told, has plenty of wonder in it.

An honest note about the subject: real physics rests on mathematics, and a popular explanation always simplifies to stay accessible. It's great for sparking curiosity and grasping the big ideas, but if you want to go seriously deep, sooner or later you'll need the books and the equations. Treat it as a good starting point, not the final destination.
