Thank you professor for all the time and effort you have put on your channel. These information you shared with us will last for ever. Cheers professor and thank you Nicole !
17:38 The difference between heat and work? The change of the PV term typically means a change of volume... so it's mechanical movement on a macroscopic scale. It's not just about usefulness... heat can also be "useful". It's the V (macroscopic mechanical movement) that's the main distinction.
The decay of a neutron in deep void of space exactly energetically compensates for the compression it will experience during its world line from decay in deep void to being neutron in neutron star and it collapses/inverts/phase changes, into the vacuum flux for a moment then emerging in deep void. Neutron decay cosmology is the thermodynamic solution to universal process.

I think General relativity and the second law of thermodynamics are twin theories because they do two similar things. 1) They both tell us that their emergent theories and that there is a more fundamental substrate and the nature of this substrate is infinite and is quantum. 2)They both tell us how to extract “useful work/information” from this infinite and quantum substrate especially how gravity is central to this process. 1) GR and 2LTD are twin theories because they both end in informational/entropic infinities as seen in singularities in black holes and they both need initial states but can’t tell us how they got to those initial states. They also tell us that there is a fundamental substrate and this substrate is infinite and quantum because quantum mechanics is the only theory that has infinity as its “base” state with the UNIVERSAL WAVE FUNCTION and through decoherence you can derive/emerge the initial state necessary for GR and 2LTD,that’s why Quantum mechanics comfortably describes singularities in black holes because they’re its true nature. You can even borrow some thinking from thermodynamics to explain how the primordial decoherence happens in the Universal wave function, by saying if you give an infinite substrate infinite time in its infinite entanglement one of its degrees of freedom is order an order that creates the first macrosystem microsystem decoherence,a decoherence that infinitely perpetuates in a fractal and holographic fashion. 2)GR and 2LTD tell us how to extract useful work from this underlying infinite and quantum substrate because they show us how the classical world emerges and persists from the underlying Universal wave function using gravity as the primary decoherence and coherence interface. GR does this by showing us how you go from the primordial decoherence to where “many worlds” or in this case multiverses emerge each with its own unique gravitational constants that create the necessary entropic gradients to allow complexity to emerge but also how that same gravity through entanglement firstly with the unique emergent universe itself where everything is constantly moving towards maximal entropy/ full exploration of microsystem degrees of freedom and secondly through blackhole gravitational singularities how these various microsystem universes are entangled to the macrosystem multiverse,thus through Ads/CFT correspondence,which is just another way of saying macro-system/micro-system entanglement, you get exploration of the degrees of freedom of the Universal wave function and since the UWF is infinite this process is infinite and perpetual because the greater the exploration of degrees freedom the more degrees of freedom are realized. 2LTD shows us that gravity is Maxwell’s demon,just like gravitational constants in GR the demon “sorting” explains the entropic gradients that lead complexity to emerge. Just like GR the demon needing some place to “store/remember” its sorting is the Ads/CFT correspondence that allows symmetrical exploration of degrees freedom of the micro system and macro system,gravity being the demon that entangles the bulk with the boundary and because the bulk is infinite the demon can continue this process of sorting or complexity realization infinitely.
I’ve thought about how one of the most important physical quantities in thermodynamics, absolute temperature, is essentially time. That there’s a direct relationship, which is actually perceivable to living organisms. When we say “time flies” we mean that as life goes on and we get older, we experience time differently than when we were younger. As kids, a long day was looooong, like at a boring day of school, but when we were playing or doing something exciting, time felt a lot shorter, “Time flies when you’re having having fun”, so the saying goes. I think this has to do with entropy, in that the increased entropy of growing older, or exerting energy in the form of play, will affect time perception. I think this phenomena is because temperature and time are two sides of the same coin. Just like mass/energy & space time are. Both phenomena may be mathematical identities of something more unified. just a thought, maybe you might appreciate it.
In the maxwell's demon problem, isn't the demon himself doing work(aka spending energy) while opening and closing the door to seperate fast and slow moving gas molecules? If this is the case then wouldn't it serve as a rough explaination for why this system should not be a perpectual motion machine?
hmmm what if i say that "work" is energy transfer through mass displacement of matter (like expanding/contracting gas) and "heat" is energy that propagates without net displacement of bulk matter (because its carried by atoms jiggling around)? yea if we're examining both work *and* heat *inside* a gas things get tough
Randomness is deterministic. That's the cool thing about reality! It's purely random, which is a simple mathematical pattern (see Pascal's triangle). Everything that possibly can happen happens, somewhere, somewhen, with very clear patterning, but it's impossible to know which particular pattern we are in. So we can't fully predict the future, only some generalities.
Since there's quantum randomness does that mean Sam Harris is wrong about not having free will since thoughts and atoms could be random and cause you to do random things that aren't predictable?
Yea I guess. I thought Sam was saying that people's behaviour was deterministic. But he's just saying that we don't have free will cos it's based on past forces or by chance
Prigogine was such an inspiration for me as a kid. That life can take what is initially random radiation and finesse it into a marmoset is pretty amazing. Almost negentropic. This is the only planet which seems to have this cool bio film on it's surface. We should try and keep this rare specimen in good condition. Oh oh looks like its been damaged by looters. Some of the jewels are missing. The Dodo for one.

I have definitely listened to this entire video. That is all.
Definitely?
I usually like it better when they overuse the word "Absolutely" instead. But, you take what you can get.
Are you sure you listened to this entire video?
Apart from the bits where you zoned out but didn't realize it?

What in the fuck

If this is the case then wouldn't it serve as a rough explaination for why this system should not be a perpectual motion machine?
The door is massless in the statement of the thought experiment (I don't know if that was mentioned in the episode) so no work is done when opening it
hmmm what if i say that "work" is energy transfer through mass displacement of matter (like expanding/contracting gas) and "heat" is energy that propagates without net displacement of bulk matter (because its carried by atoms jiggling around)? yea if we're examining both work *and* heat *inside* a gas things get tough
What's missing here is the theory of Maxwell's Silver Hammer :)

Cedric: “Yeah I don’t even know what that is man”
Levi: “Jules Verne n’ sh*t”

You aren't free if a dice roll is responsible for your actions.

Lets say that the memory in maxwell's demon *isn't* erased. what would happen?
❤
Is a Heat Pump a form of Maxwell's demond?
No because you need to put work into pump.
Where is Godels theory of time being non existent...let's make it happen.
Bravo, bravo, bravo.
The world is not anymore the way it used to be. Hmm hmm, no no no.
