Mr. Green introduces and explains the basics of special relativity. Over the duration of this recording,. Mr. Green maintains great energy and enthusiasm for the whole damn lecture . He has a particular way of gesturing and motioning with his hands that, to me at least, conveys a good deal of passion and intuition regarding the topics he is holding forth on. On top of his ability to lecture, his examples are plentiful and really Mr. Green, I'm getting brief glimpses of a young Judd Hirsch peppered throughout.

@@ImInfluence he is using one's perspective as if that changes reality. Your perspective is your point of view, example: if person is inside a one way mirror box and moving with a light clock - the person inside thinks they are stationary while the people outside the box KNOW the person inside the box is in motion. You wouldn't say the person inside the box isn't in motion (stationary), you would say the person inside the box INACCURATELY perceives they are stationary.

Excellent! - I've learned much about Relativity (Special and General), because his examples are so clear and understandable. I have a PhD in Space Science (Rice Univ. 1969). His (non-technical) explanations of Relativity are easy to follow and terrific! - Thanks, Brian (Wikipedia: Gerald J. Fishman)

I have a kitten that pays no mind to whether any given video is playing, unless Brian Greene is speaking. Every time Brian Greene - and only Brian Greene - is on a screen, she walks over calmly, sits upright at attention and watches unwaveringly until another speaker comes on. I’m not sure of the science, but I can adequately confirm that it is pretty silly.

A note on intuition...As a INFJ, the only MBTI personality type that has proven intuition and a bit of a expert on it as I sometimes experience it, Intuition is not always from our experience, intuition more often comes from the other side. I know science doesn't want to accept the idea of this, but scientists need to read all the 1000's of NDE or Near Death Experiences and they will understand intuition better and the other side.

i am not trying to be cynical. In fact, I watch your youtube shows every night. My eyes are dim because of retinopathy, but I like the way you explain things. My question is, why are we even bothering to try to find solutions to those questions that obviously cannot be answered? Like black holes, gravitons, and the smallest particles? I feel that we already know enough about the universe to be able to live in peace and hopefully be able to protect ourselves from cosmic threats. What else will we gain from knowing more about black holes which we cannot see or we cannot reach? is there even a chance that we will run into a black hole? if not, then I think we should dedicate our efforts to finding ways to achieve FTL travel and other such technologies that will help us reach the stars instead of just studying them from millions of light years away?

Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city complain about the same time paradox unless it was effected by it. Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're randomly given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? Ti-i-i-ime, is on my side. Yes, it is!

I remember when this course first came out and it had a bunch of problem sets you could complete and you could even write questions to Professor Green. He responded to one from me in a very detailed and thoughtful answer. There was a promise that they would follow up this course with a similar course on General Relativity and one of Quantum Mechanics but those never happened, sadly.

@williamwalker39 10 ай бұрын

Relativity is just an optical illusion. See my post at the top of the comments. Study Galilean Relativity, Gravitoelectromagnetism, and Pilot Wave theory. These are the true theories of Relativity, Gravity, and Quantum Mechanics. They involve absolute space and time.

Brian Greene explains String Theory and related fields in an efficient way. I read his book 'The Elegant Universe' and 'The Fabric of the cosmos' and I would not lie but besides being a 8th grader I understood String Theory and only Physicists like Greene can explain it in such simpler and efficient way.
