I was a student of physics. Today at the age of 57 I understood what entropy actually means. Thank you.
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!
I'm 5 years experienced mechanical engineering teacher. And I teach on Engineering thermodynamics and heat transfer subject. When I explain 2nd law thermodynamics and entropy to students never could do clearly it. Now i know how to explain why always entropy tends to reach maximum. Thanks
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 remember in my college statistical thermodynamics course the professor said we don't die, we just reach equilibrium.
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.
Truly mind-blowing! ❤
"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!
This has to be one of the best Veritasium episodes.
I really appreciate how the street segment of this isn't just shots of people who've been asked a complicated question and looking confused. It's been such a disease in mainly digital platform interviews for a long time. Pointless humiliation to make you feel like you've somehow legitimized what your video has to say by way of making people look stupid for not having intricate understanding of fields they don't study/work in. You're actually having an engaging discussion with them and matching their energy. It's stimulating and the insight is friendly. It's such a small part of the video yet is a powerful opening, pushing collective thinking and proper lighthearted discussion that stokes curiosity. Good on you.
It is incredible how you can explain complex topic in 20 minutes that everyone grab a basic concept of it. Love it. Keep it going.
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
This has to be one of the best Veritasium episodes. I got goose bumps because of the beauty of the explanation. Science is so awe inspiring.
How an small interesting survey in the beginning could lead to a great story about entropy is beyond my imagination. What a story teller and science inspirer. I love this channel so much.
The effort to put this presentation together and for millions to view has used energy very effectively. Please spread out more heat like this over time.
PhD physicist and engineer here. This brought an incredibly enlightening perspective for me. I must say, the concept of entropy is not a simple one... Many physicist, also as mentioned in the video, battle to fully understand the concept. This brought it all together for me. I'm having a rough night just deeply thinking about entropy because the concept is far more elegant than i ever imagined it. Thank you for this insanely amazing work.
Derek's ability to break down ideas of this level of complexity and explain them in a way that almost everyone can understand and appreciate is exactly what we need more in the world. It's education at it's finest. I applaud you.
I never got it in school. As all we did was write down the formula, derive it and cram the definition of entropy. Now I realise the real meaning of it and has made physics more interesting than ever for me. Thankyou.
I love the casual flex. "I'm a PHD physicist." 😂 Very justified. Thanks Derek!
