R. Feynman "The nature of physical laws" (second lecture)

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



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

The book "The nature of physical laws" is one of the most important in my life, when I read it in childhood, it formed a fan of my interests for the rest of my life, well, perhaps there was also GEB, which also had a strong influence. In The Character of Physical Laws, Feynman, without telling 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 the Feynman 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 lack of professionalism (I never dealt with translations), the work goes wrong quickly, as I would like, I even thought about abandoning this case, but since the first lecture caused such interest, I would be happy to continue the work. After I finish with subtitles, I have plans to make a complete translation with voice acting.

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