For those of you that haven’t taken a thermodynamics course yet, I don’t think you realize how incredibly helpful this video is lol
-
The thing about one photon from the sun turning into several spreading out in all directions answered a long standing question for me - how to explain the way the sun “powers” life on earth in terms of entropy. Thanks!
-
the three laws of thermodynamics: 1. you can't win 2. you can't break even 3. you can't stop playing the game
-
My brain hurts . But in an expansive way
-
I was a student of physics. Today at the age of 57 I understood what entropy actually means. Thank you.
-
I told my brother that if he applied to be one of your physics writers that he should tell you that I miss your street interview videos. Looks like you already had my wish on your radar!
-
What a fantastic, informative and interesting video. My PhD in theoretical physics dates to 1976 and this video has to be one of the most thought-provoking discussions on entropy that I have ever seen or read. Thank you for sharing.

-
This has to be one of the best Veritasium episodes.
-
"What the sun gives us, is a steady stream of low entropy", is the best example for entropy. Thank you for making science more approachable, Derek!
-
One thing is to know things, the other is to be able to talk about them with passion, spreading out to listeners. You really make great use of the energy you are given :)
-
The feeling of realizing the idea before its actually clarified, only to be validated a few moments later is irreplaceable. It amazes me that this kind of information doesn't give everyone the goosebumps.
-
I love the casual flex. "I'm a PHD physicist." 😂 Very justified. Thanks Derek!
-
I'm a chemical engineer, and I always hated the way they defined Entropy to us in textbooks or how teachers would explain it to us. They say Entropy is disorder or randomness which never really tells you what it is. I never completely understood the concept but watching this now after all those years it looks like yes it was so obvious, it is disorder now I get it why it is defined asdisorder.
-
I don’t usually comment on YouTube videos, actually I don’t leave comments at all, but this series is probably the best thing out right now. Thank you for empowering and inspiring me with this fantastic channel.
-
As a current Chemical Engineering student, it helps me a lot in understand this concept about entropy, because currently I'm taking Thermodynamics and Carnot Cycle is one of the foundations of understanding the relationships between them.
-
About 5 years ago discoved this show. At 69 years old your show now sends me daily down that wonderful rabbit hole... the world wide web gushing with information. I feel like I finally rediscovered the wonder and excitement of a being alive! And ready and armed to discover the unknown with childlike wonder... Thank you all for making life an incredible adventure... again!
-
I did my PhD in biophysics and I love that you mentioned life when talking about entropy. This always confuses people until they realize you’re not a closed system
-
that was so beautiful im in awe- the way you connected all these people and concepts i just im in awe. so glad you do the things you do
-
These kinds of videos prove to me how beautiful physics is and that is what gets me going on the most difficult days (in my studies). Its so weird that a great physicist like you exists around the same time that I do, and I get to enjoy all your mind blowing videos.. It is incredible indeed how beautiful and flawlessly yet so mysteriously the universe works.. Inspires me to learn more and more about these things.
