Messenger readings by Professor Richard Feynman

Last year, we began translating and voicing the Messenger's lectures of the Nobel laureate in physics, Richard Feynman , which he gave at Cornell University in 1964.

Last year we managed to publish 2 lectures out of 7. And now, thanks to our subscribers, we released the 3rd lecture, in which Richard Feynman talks about what conservation laws exist, how they work, and what similarities they have.

In case anyone had time to look, we duplicate the first two lectures of this course.
Enjoy watching!
