Entropy is surely one of the most perplexing concepts in physics. It’s variously described as a measure of a system’s disorder - or as the amount of useful work that you can get from it - or as the information hidden by the system. Despite the seeming ambiguity in its definition, many physicists hold entropy to be behind one of the most fundamental laws of physics.

I am positive that Matt just loves to say 'Von Neumann'.

this one is seriously mind blowing to me.. the more of these videos you watch, the better they get.. because over time you understand more and more and then you put those pieces together and it's like BLAM! and suddenly your concept of reality becomes so .... unreal

6:55: This guys is so into Quantum Mechanics, even his hair changes when you try to measure it.

“How quantum entanglement creates entropy”
Me: I know some of these words.
630 |
The answers at the end of this episode just increased exponentially my interest in a full PBS SpaceTime episode about the Quantization of Space. I'd really like to know more about Loop Quantum Gravity's grid of abstract connections between points, and how is possible that Space emerges only on larger scales.

This takes me back to my dissertation - “Defining work in a quantum battery” where I utilised heavily Von Neumann Entropy and the concept of temperature at the quantum level. This was a great episode and made me miss my days in academia, thank you for another phenomenal episode Matt.

11:12 — Best part:
"Our capacity to observe quantum effects like superposition depends on being able to access the entire wave function."
13 |
You sort of compressed about four episodes into this one.
216 |
After 3 viewings, I'm still entangled with confusion. More please.
53 |
I'm happy to hear your remark about von Neumann and how great he actually was: people often don't realize how much von Neumann was ahead of his time and what kind of genius he was.
20 |
Whew, definitely going to have to re-watch this one again a few times to actually grok it. Love episodes that really shift my understanding!
95 |
"Shannon Entropy" sounds like the name of a Bassist in an all girl metal band.

The movie Tenet needs to provide a link to this video in the credits.

I just want to thank you guys for all you do. I love learning about space and I have trouble sleeping. Listening to your videos before bed distracts and keeps my mind busy enough to not over think about life until i can fall asleep. Unsuccessful today since its 6:40am, but I don't know what I would have done without this for the past few years. I have listened to all your videos and been repeating them since they are amazing.

Matt O'Dowd and the crew on this show are some of the greatest science communicators of our time.

My mind was in the superposition of both understood the episode or didn't, until i broke the uncertainty with a rewatch😂
Really excited for the upcoming episode.

I didn't realize the same von Neumann whose name pops up in computer science all the time (von Neumann architecture) was also involved in thermodynamics, but there you go!
26 |
I love this episode. Everything quantum seems to make more sense now and is less daunting and unfamiliar. The visuals helped so much too. Looks and sounds like the entanglement of all particles weaving the fabric of space. Feels like a familiar warm comforting blanket rather than a feeling like being hopelessly lost driving an unfamiliar car on a super tangly spaghetti junction, in a blizzard or something. I just hope Schrodinger's cat doesn't tear apart the fabric of space time like my cat did my blankets. I mean I'd want revenge if my owner kept putting me in a box for extended periods just to contemplate weather I'm alive still or not.

How to go from superposition, to entangled quantum states to classical. This was possibly the most brilliant and insightful presentation ever! Thank you!
