  Came out in shorts and pink shirt. Blew some minds, inspired some people. Only Feynman.

  This guy is my hero. He has always been the one that &apos;&apos;guided&apos;&apos; me through science. My father once told me about him when I was 6 years old, and ever since, I&apos;ve been in love with physics and mathematics. Feynman tought me to be curious, to always want more you know? I&apos;m 16 now, and I know, that I will never stop searching, that this &apos;&apos;fire&apos;&apos; will never cease, I will always want to learn more about the Universe and everything.<br>Thanks R.P.Feynman.

  Sitting here on my 5nm architecture CPU watching this. Amazing.

  OH MY GOD. It&apos;s hard to understate the genius who was Richard Feynman. At <a href="https://www.youtube.com/watch?v=4eRCygdW--c&amp;t=1800">30:00</a> he describes the concept behind the accelerometer/electronic gyroscope computer chips which are in all of our cell phones today. They&apos;re all around you, in your car(to detect an accident that needs the airbag, for the electronic stability control), in the airplanes you fly in (autopilot). Digital cameras (image stabilization). And not just accelerometers or inertial navigation systems but MEMS gravimeters and magnetometers. They&apos;re in everything. &nbsp;<br>And he goes on to describe the same structure being used in the reverse was as an accelerometer. That is using electricity to move those microscopic pieces instead of reading the changes in voltage/current etc. when they move. WELL, he&apos;s describing the technology that&apos;s used in DLP TV&apos;s. DLP&apos;s use a very bright light and shine it on a chip that&apos;s maybe 2 inches across. That chip has millions of microscopic mirrors on the surface that are connected each to a wire and they can all be individually moved as needed in order to project that pixel of light onto the screen. It&apos;s amazing, from a 2 inch chip with mirrors that independently move which are too tiny to see with the naked eye it can project a high def picture 1080p, I think there are even 4K DLPs now too.<br><br> This was in 1984, I don&apos;t know if he described that same concept (dissolving away one material to leave a movable layer embedded in a microchip) during any of his earlier lectures, but still. He thought of it and described it decades before it was ever attempted and put to use.

  I feel like I am sitting in on the lecture, visiting from the future, just smiling and thinking &quot;Just wait a few years Richard, you will see just how right you are.&quot;

  &quot;How small can we make machines?&quot;<br><br>I&apos;d find it hard to believe we can make anything smaller than those shorts you&apos;re wearing, Professor Feynman.

  I was a first year physics student 40 years ago. Feynmann is a jewel. Get his biography for xmas.

  This video is from 1984 and is was an updated version of Feynman&apos;s classic 1959 talk, the original transcript of which is given in a link in the video description on my blog. Feynman, having given the talk in 1959, had remarkable foresight into how nanotechnology would begin to develop in his lifetime and beyond.

  It&apos;s all about fun. And finding &quot;a hook&quot; as he said himself, to get people interested. I love the way he likes to see the world. Trying always to see a different perspective, finding out different ways of seeing the same thing. And in the end, just to simply have fun with it. Analogy to things we know in our world is the only best thing we can do to imagine how it all works. And he has that gift of making wonderful analogies, to make it look simpler for a normal mind.

  This lecture reminds me that most of what engineering is is applied physics.

  He is a co-founder of quantum mechanics. He created the insight of quantum mechanics.

  Such a smart man. Have you noticed that when truly bright people explain stuff they keep off the jargon. RF wanted people to understand what he was talking about rather than impressing them with his intellect. Every public speaker could learn a little something here. Thanks for posting this one Mu. I&apos;m enjoying your channel.
