If you love art you also love paintings. Have you painted any oil paintings of your own? If you haven't I think you should give it a try and paint something related to physics or physical phenomenal. In that way you could combine your "life" and "love" together.

Dear Walter I am a Civil engineer ( Structural) of 62 years old, during this period of Covid I found your lectures about two weeks ago in RUvid , and was shocked with them , you made so effect, that have looked most of your lectures and interviews, also downloaded and read your book , as could not purchased it because amazon or e-bay are not sending them to Chile , will try after the pandemia. When I studied Physics at school at 17 years old , I probably was not mature enough so had many problems , for example could not understand that if I pushed the wall the reaction of the wall was a force equal and against me, as you say in your lectures, for me was not intuitive. At university of course studied a lot and was forced to learn , in line also with mathematics ,calculus , etc, also in the courses oh hydraulics , electricity , structure análisis we applied all that knowledge but with the years you start to forgot a lot of those important concepts that you show in your lectures and that you brought up again. I just wanted to write this, and hope it will reach you , to thank you for bringing me again the love of science and physics I will look again your lectures in chronological order and can tell you that are waiting anxiously for the next rainbow to see if can find the white zone , where is the red and if I lucky see the second one with the colors inverted.

I saw the representatoon of the sun as a pale green, not white and when you said you can see it turning red I did not see red. I am not color blind because I am able to see red.

When I see that, I regret it that I didn't study physics. It would have been a pleasure for me. I admire her ability to teach things so playfully simple but understandable. Thank you. Thanks for the fun hour. Thank you for your life's work

Some are watchers and some doers. In the doers some ' go through motion , like the pendulum" but some show flair like a Faraday coil with LED lights and than there are those that are showmen like prof Lewin. If he wasn't teaching physics he would have been performing on broadway. But don't mistake, the true geniuses like Dirac and Einstein never had showman ship, both are mutually exclusive. Prof Lewin understood a piece of the puzzle well enough to use that as fulcrum for his swing. He never dwelled for a moment on the meaning of things, the cosmic order or the majesty of nature. Don't take it as negative square root of Prof Lewin, he did good, but its like a show on public TV on healthy eating or TED talks, good for passing time in quarantine, but make you no wiser
