Why am I watching this in the middle of the night when I am a law student and have three essays to write

[highcheese]

Einstein is always shown as an old man, but it's interesting to note he was a very young man when he published these theories.

[grapiken]

This is perfect. No gimmicks, no background music. Just clear simple information. It still takes mental gymnastics getting your head around it all. Thanks for the great video.

[DoctorGlitch]

I can’t Believe I’ve been browsing videos for the past 7 days and i think i finally understand now. Thank you so much

[lagj]

The clear explanations, combined with extremely pleasant voice and diction, makes this video a pleasure to listen to.

0:10 -Classical Relativity
1:25 -Time Dialation
3:33 -Length Contraction
4:45 -Time Travel
5:29 -General Theory of Relativity
6:14 -How do you know it's true

Hope it helped you a lot

It’s 2:34am and I have my finals tomorrow morning but look at what I’m watching. I’m a fashion student but DAMN IS PHYSICS ADDICTIVE OR WHAT

Teacher: you're 15 minutes late to the class
Me: well, time is relative.

[rutee]

This explains why when I'm standing still or procrastinating time seems to get away from me, but when I'm moving I feel like I have plenty of time.

[ajesusencounter]

Woah that part about the alarm clocks being at different times is astonishing. The universe is full of wonders...

[ムシムシ]

Theory of relativity is not hard to understand but hard to believe!

[akshat]

When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute — and it's longer than any hour. That's relativity.”
- Albert Einstein

Can you explain the Theory of relativity in
45 days so that I can understand.

[davidangel]

Just want to thank you! This is amazing. You have a real gift of simplifying insanely complex concepts. I really enjoyed it.

[stroys]

I studied relativity in my college physics course in 1974. As a math major the equations were easy to follow. For anyone without a strong math education this is a terrific explanation. Well done! Thx

[SCP--sffu]

That Speed = Ddistance/Time demonstration was SOOO HELPFUL! I've always been told the time is relative but no one's ever fully explained it.
Thank you for this video!

Who left the kids to play in moving truck

[samueljaihindh]

Awesome.. "Interstellar" brought me here.. I am somewhat clever now. Very Simplified explanation.

[muhammadnabeel]

I rarely comment on YouTube but your video really forced me to sign in and comment. I thought, it would be more better to visualize this concept just in few mins before watching Interstellar. And after watching this video, I can easily comment that, this is one of the most interesting and attractive videos I have ever seen. Thanks for sharing :)

[khanumersalim]

I have watched many many videos but I was unable to understand, but literally literally this video helps me to understand about theory of relativity, the speaker explains in such an easy way that it was easy, very easy to understand . Thanks a lot to the speaker.
