R. Feynman “The Character of Physical Laws” (second lecture)

I present to you the second lecture of seven read by a Nobel Prize winner, Professor Richard Feynman, at Cornell University in 1964, which was called "The Connection of Mathematics and Physics."



I am convinced that there is no popular science, only its popular interpretation. And this is not my favorite genre, now I practically do not read scientifically popular books, science does not deserve to glide forever on the surface. However, I still read some books and I advise you, wrote a lot and delightfully: Bohr with Einstein (any popular text, especially I recommend their correspondence), Pauli (correspondence), Heisenberg “Part and the whole” (this is more a philosophy in Wittgenstein’s style), Wittgenstein himself, Quine “Two dogmas of empiricism”, David Deutsch, “The structure of reality” (with reservations, it’s absolutely a wonderful thing), again in Feynman’s quantum mechanics, “QED is an amazing property of light and matter”, logically - GEB Hofstadter (Godel, Escher, Bach) - a book of my childhood, in biochemistry Frank-Kamenetsky “The Most Important Molecule” is a wonderful book about DNA, of course I advise James Watson “Double Helix. Memories of the discovery of the structure of DNA. "
And the mass of books that I did not remember was breathtaking from all of these books, but unfortunately on the shelves in bookstores they disappeared into the stupid noise of some dubious scientific literature. And I do not really understand what actually people who are interested in science are reading right now.

The book “The Character of Physical Laws” itself is one of the most important in my life, when I read it in childhood, it formed a fan of my interests for life, well, it was probably GEB, which also had a strong influence. In The Character of Physical Laws, Feynman, without speaking about the laws themselves (well, except for the first lecture), explains the structure of all modern physics. This is an amazing book and I love it very much. Therefore, the idea of ​​translating Feynman's lectures (which formed the basis of this book) was especially close and interesting to me, but due to the large volume (7 hour lectures, almost half a million characters) and my unprofessionalism (I never did translations), the work is not going well quickly, as I would like, I even thought of abandoning this matter, but since the first lecture aroused such interest, I will continue to work with pleasure.

Lecture list:

UPD In this lecture, from 15:54 Feynman conducts 2 proofs (analytical and geometric) of the equality of the area of ​​two triangles . This is the most difficult part of the lecture, both for translation and for understanding, I have a question for you, how clear is it, do you keep up with the thought and subtitles, or do you need to somehow edit this piece to make it more understandable?
Well, as always, I will be grateful for the errors found, inaccuracies and other tips.
