Richard Feynman - The.Character of Physical Law - Part 1 The Law of Gravitation (full version)

Richard Feynman - The Character of Physical Laws [VIDEO] Incredible talk for both the content and the form ! There is so much we could learn from him.

Physics is just mindblowing. When I think deeply about the fact that things that are moving will keep on moving forever unless a force acts on them, and the fact that no one knows why it's true (and that the question may not even have any meaning), and that my body is nothing more than a very advanced method of propagating genetics, then... well, it's just a lot of fun to think about! The fact that there are mysteries that no life will ever have answers to is quite humbling. If you find physics interesting, then you'll love these Feynman lectures. Feynman is so good at explaining these concepts that you don't even need any formal training to understand them.

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. [0] [VIDEO]

The Feynman Lectures (on Physics) are incredible - Feynman had such an amazing mind, one of the greatest the world has known, yet could explain complex things like he was talking to a friend in the living room over drinks. Never patronizing, always amusing & informative: [VIDEO]

It's kind of a classic, but I really enjoyed Richard Feynman lectures[0], especially on subjects I thought I knew well. [0] - [VIDEO]

If you haven't seen it yet, Feynman's podcast series The Character of Physical Law is quite wonderful: [VIDEO]

"Beauty", in science and mathematics, is not a quality of the object regarded so much as it is a pattern-recognition response in the one regarding it. Patterns which are predictable are naturally pleasing to us because our pattern-recognition abilities evolved to harness the patterns of nature for prediction of outcomes. Predicting and harnessing outcomes based on patterns may be the power that humans posses in strength over the other animals. It should not be the case that exploration of an outcome is excluded on the basis that it is not perceived as beautiful. However, that there are patterns among the laws of nature was one of the fundamental discoveries of our species and a guiding principle of modern science. Richard Feynman said[1]: "Nature uses only the longest threads to weave her patterns, so that each small piece of her fabric reveals the organization of the entire tapestry." [1]: [VIDEO]

I always thought that this was interesting... I am sure that many of you are familiar with Dr. Feynman's 7-part lecture series entitled The Character of Physical Law , which were part of the "Messenger Lectures" [1], given at Cornell University in 1964. In the first lecture, Law of Gravitation - An Example of Physical Law , Feynman states the following: "Question: what is the ratio of the gravitational force to the electrical force? That is illustrated on the next slide. The ratio of the gravitational attraction to the electrical repulsion is given by a number with 42 digits, and goes off here: all this is written very carefully out, so that's 42 digits. Now, therein lies a very deep mystery: where could such a tremendous number come from? That means if you ever had a theory from which both of these things are to come, how could they come in such disproportion? From what equation has a solution which has for one, two kinds of forces, an attraction and a repulsion with that fantastic ratio? People have looked for such a large ratio in other places. They're looking for a large number. They hope, for example, that there's another large number. And if you want a large number why not take the diameter of the universe to the diameter of a proton. Amazingly enough, it also is a number with 42 digits." [2] [1] [LINK] [2] [VIDEO]
