Edit: apparently, I have been misinformed for a very long time. These are still excellent lectures to watch though!
The Feynman Lectures are now on Youtube[0], and I like to watch them (all of them) every few years. I highly recommend that if you've never seen them, you take some time and watch them- really watch them. Close the other windows, turn your phone to do not disturb, and really watch these masterpieces of education.
These lectures are different from his famous Lectures on Physics. The lectures you linked to were compiled in "Character of Physical Law" and are not related to his Caltech undergraduate courses where he presented his "Lectures on Physics" content.
To be more clear, the lecture series you are talking about is called "The Character of Physical Law" and is not the same content that one would get from reading "The Feynman Lectures on Physics", which is a rigorous course in most of undergraduate physics. But I highly recommend the "Character" series. Just wanted to avoid having people think they're the same thing.
