Story time with Wolfy

Prof. Wolfram, this presentation was incandescent!

Thank you Professor. You bring hope back to Science by digging deep and sharing your honest thoughts. These... Videos are priceless.

Thank you for sharing this. It is something that needs to be documented. I hope your team is also uploading this to KZread alternatives and backing up your videos somewhere offline for future generations.

Many thanks for taking the time and care to put this together and share this. I eagerly look forward to the next installment!

This is great watching you go through the historic development and reading primary resources. I've just learned of geometric algebra and it amazes me how simple yet powerful it is, and somehow it came relatively late in the development in mathematical physics and later computer graphics. I hope you keep doing these. Your energy is next level! Btw I bought your book 20 years ago :)

39:10 the idea that heat is raleted to the random motion of molecules is an ancient idea, thats why D. Bernoulli said that is well known. In particular D. Bernoulli knows about it from the book De Rerum Natura of Lucretius. This book was the inspiration for the kinetic theory of gases.

Thank you, Stephen Wolfram!

Washing dishes and cleaning house while listening to this + this is a mega habit for me = In 10 years I will be 10x smarter than all of my friends combined. I am 27 and people already comment on my intelligence and say I somehow know everything about everything … it pays to have good habits 🤷‍♂️ I used to be an idiot drug addict in my earlier years… so also have very strong grip of spirituality and happiness in life… and am very financially literate… and learned programming and so much more… idk why but this is a habit, my new addiction, and people like this and such channels give me the ability to be this way, for which I am infinitely grateful… I don’t know where I would be today if it wasn’t for such videos and an abundance of just raw beautiful knowledge and discussion online… thank you for making this, it brings me great pleasure. Earned a like and subscribe from me :)

Primary source material makes this extra captivating.

Bravo, Stephen. Love the historical background. It's a deep dive into the way natural philosophy/physics was performed at the time and the kind of issues that consumed the thoughts of scientists then. Very interesting and revealing.

Wolfram is certainly among the world's most underappreciated genuises. Also I need to upgrade my signature to the level of Carnot lol

The Victorian era often comes across as boring and stuffy, but the scientific culture was amazingly productive, with guys like Kelvin and especially Maxwell laying the foundations of modern physics. Are we seeing a rebirth of Victorian-style optimism in the tech giants of today? Great lecture BTW. Thank you Stephen! More please, perhaps the history of, oh I don't know, electromagnetism, relativity and quantum mechanics. That should do for a start!

I had to watch this twice!!!! Fascinating!!!!!!!

SW: @43:45 you make what I consider a prescient comment about the current Cosmological Concordance Model: "a dynamical theory of space ... dark matter will turn out to be something to do with the structure of space". As a mathematician it is likely for you to understand that Dark Matter and Dark Energy seem to be maths constructs to fit the data. Surely, GR is remarkable and must be taken seriously but what we have now, IMHO, is not without major philosophical difficulty. Again, thank you for making this comment. BTW, I am not a proponent of MOND but it and others should be considered along with GR as Cosmology is considered. To your history of the 2nd law - it was lengthy yet its historical complexity was given a fair hearing by you and I did follow it along. Thank you.

I thought that was Exactly what it was. But Observational Data. Such that any Calculation done without such a Math Construct would not represent the Reality of what we Observe. So yes a Math Construct. But for example if we discover like GR that Space is warped somehow, that Math Construct would fit exactly. Am I wrong? We are just plugging in numbers to fit with what we see. Now I have had the thought that what we see. Hubble's Law. Maybe that is Wrong. So it LITERALLY is a Math Construct with no Relation to Anything because the Observational Data is being skewed somehow like Quantum Observer Effect. A limit to the Doppler Shift? Something affecting the Shift? Something like that.

I never knew the victorian scientists used such poetic language in their scientific documents. You could probably use it as inspiration for some pretty cool literature.

Galileo was referring to one particular aspect of heat, by Prevost called 'free heat'. That aspect is, as Galileo said, 'subtle'. Galileo regarded it as a kind of 'substance'. Today, we call the 'atoms' of that 'substance' by the name 'photons'.

Great topic, I believe Stephen is correct about how entropy is like encrypted information, that it looks like randomness from a macro perspective but could in fact be deterministic (except I think that causality can also come from the future and explain things like strong emergence if there is such a thing). And Leonard Susskind said that entropy is simply hidden information.

@@Anders01 All Systems are Complex when SHIFTING ENTROPY. You can see this quite clearly when you have coffee and milk. Then mix them together. The initial and final states are quite simple as compared to the Middle State of Mixing Coffee. That is what we are. Between the Low Entropy Big Bang and the High Entropy Heat Death. We are the increase in complexity that is associated with the Middle Part. So no actually. Intermediate Complexity is a fact of shifting Low to High Entropy. Not just this process. Every single one. And this gives us the MOST logical explanation of evolution. Carbon wants to be Hydrogenated. CO2 is not the Lowest Entropy version of Carbon. Such that Organic Intermediates may have been created to eventually bring Carbon to Methane. Source: Sean Carol. Susskind is the man and I hope he finds quantum gravity but Carol is really a G at explaining the Meta Physics or Emergent ideas. I studied Biochemistry in college and I have looked at entropic processes of molecules hundreds of times but never put together the Idea of the Middle Complexity blown up to Cosmology. That is genius and explains All Complexity. With a couple assumptions. The Universe must be Finite or be able to come to final equilibrium. Finite in Future as we know its Finite in past.

great history

01:10:42 Still used in astrodynamics (vis-viva equation).

This story looks to be inevitably recursive and although my brain prefers things to be sequential, this cannot be with out editing much of the history.

Very good discussion of the history of the second law. However this is not always the "best"(most efficient) way to learn or build the neural architecture necessary to comprehend the second law and wrap your mind around the validity/rigor of the proofs and how they follow from "counting" and your other assumptions (all the way down to things like the axiom of choice). If you already have built those circuits and have a firm foundation, it's very useful to spend some time with Jaynes' papers on information theory and statistical mechanics as well as Tulsty's work on the emergence of information encoding channels in biological systems starting with the colorful origin of the genetic code (related to the "map coloring problem" which should be familiar to students of both CS and mathematics). Huang's textbook is also a very good reference to keep nearby. We only recently understood HOW to teach statmech and QM in a way that builds the connections between brain cells necessary to escape what I call the prefrontal cortex logic trap... you really do need to develop different circuits hardwired to think in other geometric topological and algebraic spaces than the seemingly Euclidean utopia we appear to inhabit (for example: the delay in adapting or remodeling neural architecture and maping it to the "comprehension" of new problem spaces may explain why proficiency in tasks like chess, though correlated with intelligence, do not measurably transfer to the acquisition of other skills once intelligence is controlled for). However, reviewing the history of how we went from observation to logic to testable mathematical models to conclusions capable of conferring an understanding of the generative processes behind principles like the second law is a wonderful exercise to if you want to get the feeling for how we move from the well characterized tame space of "accepted" science back into the unknown to find new phenomenon and refine our understanding of the universe.

I recommend Annie Ernaux's "The Years". :)

Minute 14:15…. Although the object being moved may not be “expressing” heat Heat is required to move an object: as such it “experiences “ heat just though it is not aware of it.

I am curious to know if you are aware of the work of Daniel P Sheehan, Univ of San Diego, who has published books and many papers about Challenges to the 2nd law. He too did a detailed review of the underpinnings of the (many versions of the) 2nd Law...(ISBN 1-4020-3015-0), and has developed a number of experiments demonstrating exceptions. I'd hoped to find him in the bibliography.

Stephen is using the word 'heat' in a way partly different from that of thermodynamics. In thermodynamics, heat is energy in transfer by mechanisms other than thermodynamic work or transfer of matter. In thermodynamics, radiation is a mode of transfer of energy as heat. Friction and percussion are modes of conversion of mechanical work into heat. Conduction is another form of transfer of energy as heat. The passage of electricity through a body, either as direct or alternating current, is another mode of transfer of energy as heat.

Monads are the base currency of energy, let’s pay homage to those before us. Call them what you will.. holons, atoms of space, etc etc. The self referencing N-sphere lattice is the perfect scalar field as the datum of nature. Where I seem to diverge from Dr Wolfram is the fact that I believe all the parallel worlds of 4D space time AND the entire set of hyper objects and their own parallels are all equally real in the literal sense. The parallel world sheets of all objects provide the lateral buttressing (branchial space) of each possible movement for your specific reference frame and hierarchical level to stay consistent. The neighboring (adjacent) world sheets are of course also describing the super-positional footprint of the objects 4D integral. These superpositional footprints are what we now call dark matter, looking like place holders on your personal world-sheet, but very real for your doppelgänger. The transcendent worlds of gauge theory are very real vantage points (platforms, mezzanines) providing the foundation to our 4D finite experience. Our thread of time (in the drs language) is defined as our own 2D graph, growing with every moment as our minds update the data set. We live in a observationally generative experience on a 3D slice of the N-D bulk of all possible configurations, caged in a body that anchors us in time. The hyper lattice of N-spheres provide a perfect sponge like medium for GR to express itself in, its self referencing nature curling back on itself in the presence of mass on your personal world sheet. In other words, a proton is a standing wave in this ND medium, but only records itself on your personal history sheet when your mind consumes it. Finite particles borrow their energy from their surrounding ND lattice, and this borrowing mechanism expresses itself as deformed spacetime.

Really fun and very enjoyable, and I am a lay person...😂 ❤

Parker "why specifically IR radiation and not other EMR" Is that the Parker I know? Infrared Radiation is given off at certain energies that is produced by the Vibration-Rotational movements of Molecules and Atoms as they return to the Equilibrium from constant Dipole Shifts. These energies are can literally be thought of as Vibration. Take an Atom at Absolute Zero. Vibrate it. The first Wave you produce is Radio. And as your increase the Vibration or "Heat" it gives off Waves along the Electromagnetic Spectrum. Black Body (an idealized opaque, non-reflective body) when heated gives off Thermal Radiation at Room Temperature. This can be the basis in your mind for why in General things give off Thermal Waves at the Temperature we Live In. Everything gives off IR above Absolute Zero. But because you are 98 degrees your perception of Snow for example is that it gives off no Heat. That is not the case. Like the Observer Effect in Quantum our relative perception of Heat makes this confusing. The general pattern is that as you Vibrate something. When we can measure 25 degrees Celsius. That thing gives off mostly Infrared Radiation. The Black Body graph gives you the generalized idea of how energetic something must be vibrating to give off the associated waves. This is different for all things. This difference in Wavelength emission and absorption between Elements and Chemical functional groups is the basis for Infrared Spectroscopy. This is how we know what Stars are made of. This is how we determine atmosphere of planets Light Years away. We have figured out that Giant Clouds of Hydrogen permeate the Universe because Light from Quasars are oddly shifted at Hydrogen Regions. Example the Carboxyl Group Carbon double bonded to Oxygen with two lone pairs of electrons C=O has absorption at 1500-1800 cm-1. So light passes through the Atmosphere of a Planet hits C=O and then we measure it. This is evidence of Organic Compounds. EM Radiation is constantly given off by all things. It is simply the energy at which that thing is at which determines the Wavelength. And for most living things that is IR. It gets pretty Metaphysical after that. Like why is Carbon the basis of life. 4 Valence Orbitals but is that it? Just the nature of things? Or why does Water Tension occur such that Life wouldn't exist without it. Think of the Sun. Because of its Energy it is giving off every single type of EM Radiation. You get Cancer because UV rays. We exist because of Visible Light rays. The sun warms us through IR Rays. Aurora's are made by Gamma Rays. Everything gives off all EM but the Energy and Geometry will essentially determine what Wavelength exists the most. It has been awhile since I studied Chloroplasts but I imagine they evolved from opposite logic from my last sentence. They evolved a Geometry which can take a Wavelength and turn it into energy. Sorry for Rant. One Sentence Answer. Because Rotational/Vibration movements of Atoms Energy correlates with IR Wavelength.

OK, so try this out. In memory, as we look back over the years, we lose track of the day to day happenings. Memory blurs and we only remember patterns. So though each day is discrete and computationally irreducible, observers like us find patterns wherever we can find them. :)

Interesting question. Isn't that the kind of thinking that led to postulating absolute zero?

I think it's unfortunate this law was ever labeled a "law" because then people get rather intolerant of questioning it. Clearly this "law" is a very useful observation, especially of macro scale systems. Yet we can violate it, as demonstrated several times in papers in the last 2 decades. I feel that when people cling too tightly to a belief they get emotional when you challenge them, which is annoying because I love to discuss ideas, but it's useful to step back and remember that the history of science is an evolution of ideas.

I'm surprised Maxwell's demon is so often enthusiastically dismissively bundled in with Santa Claus & the Tooth Fairy. It's so easy to think of numerous passive demons which require no energy input. Essentially it's just passive sorting. Difficult to do on a molecular scale. Easy to do on a macro scale, eg one way door or ratchet or diode type mechanism to demonstrate the idea.

Some weather satellites have infrared sensors designed to have maximum sensitivity at about the same frequency as the peak blackbody energy output of an object at 20 degrees Celsius. I think the voltage on those sensors themselves without the capacitors without power input would be extremely small but non zero. They are similar to a photovoltaic cell but using infrared from heat instead of sunlight. I don't see why you can't extract energy using the photoelectric effect with a photovoltaic cell optimized for absorbing IR at approximately 10um wavelength in a giant box of uniform temperature & pressure gas at 20 degrees Celsius? So ... How is that not violating 2nd law... Maybe I'm wrong but I don't see how. I'm not claiming with certainty any of this violates the holy law, but Im just trying to provide food for thought. You can tell I have my strong doubts that this law holds true on all scales.

re: "mnemonic entropy". This is what the writer of Ecclesiastes was suffering from. Explanation: as you get old, you see patterns in everything, so you lose the freshness and wonder and awe you had as a child. We must regain that wonder, or we'll just lay down and die. Entropy being what it is, we will eventually lay down and die. But seize the day today. Work is the thing that overcomes entropy, so apply yourself, put yourself forward this day, whether you're 9 or 99. :)

Read Lucretius poem 'on the nature of things' about ancient epicurean atomic theory, and you'll find that something very much like the second law was a motivation for basic particles, called atoms. If stuff can keep subdividing for ever, we will end up with some grey mix, irreversible. Life, and eg. an oak growing from an acorn, is possible thanks to the existence of basic building blocks, to build it from.
