WSU: Special Relativity with Brian Greene

Күн бұрын

Physicist Brian Greene takes you on a visual, conceptual, and mathematical exploration of Einstein’s spectacular insights into space, time, and energy. In just 11.5 hours, using nothing more advanced than high school algebra, journey from Einstein’s earliest musings on the speed of light to his startling realization that time can tick at different rates to his revolutionary discovery of the world’s most famous formula, E = mc2.
This is a more in-depth and mathematical version of the WSU Master Class “Space, Time, and Einstein.” • WSU: Space, Time, and ...

Loved when he was explaining where gamma should go, and how physicists just think should it be bigger or smaller? I have been doing this a lot and wasn't sure how everybody else would do it. Special relativity and physics always gives me the feeling that we can attain speeds near the speed of light without having to deal with mass and friction and whatsoever from the classic physics because I feel just like how there is time dilation, there will be space dilation as well, and using that we can fly at higher speeds relative to the observer, but not relative to the source, thus the physical forces won't really matter. This is IMO directly related to expansion of the universe.

Thank you so much Brian Greene for doing so much for us. While we have no access to good quality education, your work is helping us through. Please cover general relativity topic too, I am excited to learn it from you.

FANTASTIC UPLOAD - For all of the bad publicity social media/Internet gets in dumbing down people ( and partially justifiably so ), we also have wonderful resources like this, which educate and inform us in an entertaining and easily understood way. Thoroughly enjoyable👍👍👏

Brian Greene takes something that is difficult and dull and turns it into an 11-hour of scintillating and exciting subject is as impressive an accomplishment as Einstein’s achievements. This is not to take anything away from the great Einstein!

I hate maths, I hate physics... But OMG... I can watch, listen and learn from Prof Greene all day long. Although my main interest is cosmology and cosmic things in general, I am absolutely fascinated by all of the stuff shown and explained here. Some of the stuff required rewinding and watching again so I can understand but these 11 hrs answered a lot of the questions I have had recently. And I have a lot of questions. My daily life has nothing to do with maths and physics but the likes of Bryan Greene, Neil DeGrasse Tyson, Janna Levine and many more just make my life so much interesting and make me ask more and more questions and seek answers that modern astrophysicists and cosmologists seek answer to. Thank you prof Greene for that enlightenment. Really was interesting.

It was an awesome experience to learn from such a great physicist Dr.Brian Greene.This lecture is like a treasure for those who are physics enthusiasts. The way he explained the things through animations & graphs made us learn the things to bones. I have even made the notes of his lecture as I wanted to get all the things into my mind and didn't want to leave any piece of information. Thanks a lot sir Brian Greene!!!!!!!!!!!!!!🙂

Re Time Dilation Examples: you should note in your teaser about the symmetry breaker that there's a change in velocity at the initial launch as well as at the waypoint and that the launch could have occurred somewhere out in space such that the ship simply cruises by the Earth at the start of the experiment.
