steev hiseMy computer is dying. Heat problem. A fan is failing.  The part is discontinued. the laptop is only 5 years old. Having trouble finding the exact part# for the fan assembly even on like Ebay and Amazon and Alibaba. Can't afford new computer. Need new glasses too. Can't afford them either. can't afford my insurance premiums either. might just cash in my IRA. It's tanking with the stock market anyway. It struck me this morning that money is like energy, and like energy you can inject more of it into a system to lower the total entropy of the system, but without it the entropy just keeps increasing. Conversely as DOG(e)(gy) sucks money out of the US system, the entropy is increasing at a really fast rate, and goddess knows where the chaos will lead us.anyway. this text is from my Patreon.

Project GutenbergWhat Is Entropy? A Measure of Just How Little We Really Know.Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world than a reflection of our growing ignorance. Embracing that truth is leading to a rethink of everything from rational decision-making to the limits of machines.By Zack Savistky<a href="https://www.quantamagazine.org/what-is-entropy-a-measure-of-just-how-little-we-really-know-20241213/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.quantamagazine.org/what-is-entropy-a-measure-of-just-how-little-we-really-know-20241213/</a><a href="https://mastodon.social/tags/books" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#books</a> <a href="https://mastodon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://mastodon.social/tags/physics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#physics</a> <a href="https://mastodon.social/tags/entropy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#entropy</a>

Hari TulsidasBlack holes hold a perplexing mystery: their entropy is proportional to the area of their event horizon, not their volume, unlike other physical systems. Stephen Hawking’s work on black hole radiation showed they have temperature and entropy, but why is this area dependent? It challenges our notions of how information and energy behave at cosmic scales. This could hint at hidden principles reshaping how we think about space, information, and reality. <a href="https://masto.ai/tags/BlackHoles" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BlackHoles</a> <a href="https://masto.ai/tags/Entropy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Entropy</a> <a href="https://masto.ai/tags/CosmicQuestions" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CosmicQuestions</a>

SelfAwarePatternsWhat is the relationship between information, causation, and entropy?The other day, I was reading a post from Corey S. Powell <a href="https://invisibleuniverse.substack.com/p/you-are-a-ripple-of-information" rel="nofollow noopener noreferrer" target="_blank">on how we are all ripples of information</a>. I found it interesting because it resonated with my own understanding of information (i.e. it flattered my biases). We both seem to see information as something active rather than passive. In my case I see it fundamentally related to causation itself, more specifically a snapshot of causal processing. Powell notes that Seth Lloyd has an excellent book on this topic, so I looked it up.Lloyd’s 2006 book is called <a href="https://www.amazon.com/Programming-Universe-Quantum-Computer-Scientist-ebook/dp/B000GCFBP6/" rel="nofollow noopener noreferrer" target="_blank">Programming the Universe</a>, which by itself gives you an idea of his views. He sees the entire universe as a giant computer, specifically a quantum computer, and much of the book is about making a case for it. It’s similar to the “it from qubit” stance David Chalmers explores in his book Reality+. (I did <a href="https://selfawarepatterns.com/tag/chalmers-reality/" rel="nofollow noopener noreferrer" target="_blank">a series of posts on Chalmers’ book</a> a while back.)One of the problems with saying the universe is a computer is it invites an endless metaphysical debate, along with narrow conceptions of “computer” leading people to ask things like what kind of hardware the universe might be running on. I’ve come to think a better strategy is to talk about the nature of computation itself. Then we can compare and contrast that nature with the universe’s overall nature, at least to the extent we understand it.Along those lines, Chalmers argues that computers are causation machines. I think it helps to clarify that we’re talking about logical processing, which is broader than just calculation. I see logical processing as distilled causation, specifically a high degree of causal differentiation (information) at the lowest energy levels currently achievable, in other words, a high information to energy ratio.The energy point is important, because high causal differentiation tends to be expensive in terms of energy. (Data centers are becoming a major source of energy consumption in the developed world, and although the brain is far more efficient, it’s still the most expensive organ in the body, at least for humans.)Which is why computational systems always have input/output interfaces that reduce the energy levels of incoming effects from the environment to the levels of their internal processing, and amplify the energy of outgoing effects. (Think keyboards and screens for traditional PCs, or sense organs and muscles for nervous systems.)Of course, there’s no bright line, no sharp threshold in the information / energy ratio where a system is suddenly doing computation. As <a href="https://www.quantamagazine.org/computation-is-all-around-us-and-you-can-see-it-if-you-try-20240612/?mc_cid=7fb4d2145a" rel="nofollow noopener noreferrer" target="_blank">a recent Quanta piece pointed out</a>, computation is everywhere. But for most things, like stars, the magnitude of their energy level plays a much larger role in the causal effects on the environment than their differentiation. However, people like Lloyd or Chalmers would likely point out that the energy magnitude is itself a number, a piece of information, one that has computational effects on other systems. In a simulation of that system, the simulation wouldn’t have the same causal effects on other physical systems as the original, but it would within the environment of the simulation. (Simulated wetness isn’t wet, except for entities in the simulation.)Anyway, the thing that really caught my eye with Lloyd was his description of entropy. I’ve covered before <a href="https://selfawarepatterns.com/2021/10/24/reconciling-the-disorder-definition-of-entropy/" rel="nofollow noopener noreferrer" target="_blank">my struggles with the customary description of entropy as the amount of disorder in a system</a>. Disorder according to who? As usually described, it leaves the question of how much entropy a particular system has as observer dependent, which seems problematic for a fundamental physics concept. My reconciliation of this is to think of entropy as disorder for transformation, or in engineering terms: for work.Another struggle has been the relationship between entropy and information. I’ve long wanted to say that entropy and information are closely related, if not the same thing. That seems like the lesson from <a href="https://en.wikipedia.org/wiki/Entropy_(information_theory)" rel="nofollow noopener noreferrer" target="_blank">Claude Shannon’s theory of information</a>, which uses an equation similar to Ludwig Boltzmann’s for entropy. Entropy is a measure of the complexity in a system, and higher values result in a system’s energy gradients being fragmented, making much of the energy in the system unavailable for transformation (work), at least without adding additional energy into the system.However, people like Sean Carroll often argue that a high entropy state is one of low information. Although Carroll does frequently note that there are several conceptions of “information” out there. His response makes sense for what is often called “semantic information”, that is information whose meaning is known and useful to some kind of agent. The equivalence seems more for “physical information”, the broader concept of information as generally used in physics (and causes hand wringing due to the possibility of black holes losing it).Lloyd seems to be on the same page. He sees entropy as information, although he stipulates that it’s hidden information, or unavailable information (similar to how energy is present but unavailable). But this again seems to result in entropy being observer dependent. If the information is available to you but not me, does that mean the system has higher entropy for me than it does for you? If so, then computers are high entropy systems since none of us have access to most of the current information in the device you’re using right now.My reconciliation here is to include the observer as part of the accounting. So if a system is in a highly complex state, one you understand but I don’t, then the entropy for the you + system under consideration is lower than the entropy for the me + system combo. In other words, your knowledge, the correlations between you and the system, makes the combined you + system more ordered for transformation than the me + system combo. At least that’s my current conclusion.But that means for any particular system considered in isolation, the level of entropy is basically the amount of complexity, of physical information it contains. That implies that the ratio I was talking about above, of information to energy, is also of entropy to energy. And another way to refer to these computational systems, in addition to information processing systems, is as entropy processing systems, or entropy transformers.This might seem powerfully counter intuitive because we’re taught to think of entropy as bad. Computational systems seem to be about harnessing their entropy, their complexity, and making use of it. And we have to remember that these aren’t closed systems. As noted above, they’re systems that require a lot of inbound energy. It’s that supply of energy that enables transformation of their highly entropic states. (It’s worth noting that these systems also produce a lot of additional entropy that requires energy to be removed, such as waste heat or metabolic waste.)So computers are causation machines and entropy transformers. Which kind of sounds like the universe, but maybe in a very concentrated form. Viewing it this way keeps us more aware of the causal relations not yet captured by current conventional computers. And the energy requirements remind us that computation may be everywhere, but the useful versions only seem to come about from extensive evolution or engineering. As Chalmers notes in his book, highly computational systems don’t come cheap.What do you think? Are there differences between physical information and entropy that I’m overlooking? And how would you characterize the nature of computation? Does a star, rock, or hurricane compute in any meaningful sense? What about a unicellular organism?<a href="https://en.wikipedia.org/wiki/File:Entropy_flip_2_coins.jpg" rel="nofollow noopener noreferrer" target="_blank">Featured image credit</a><a href="https://selfawarepatterns.com/2024/07/28/entropy-transformers/" class="" rel="nofollow noopener noreferrer" target="_blank">https://selfawarepatterns.com/2024/07/28/entropy-transformers/</a><a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://selfawarepatterns.com/tag/causality/" target="_blank">#Causality</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://selfawarepatterns.com/tag/computation/" target="_blank">#Computation</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://selfawarepatterns.com/tag/entropy/" target="_blank">#Entropy</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://selfawarepatterns.com/tag/information-theory/" target="_blank">#informationTheory</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://selfawarepatterns.com/tag/philosophy/" target="_blank">#Philosophy</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://selfawarepatterns.com/tag/physics/" target="_blank">#Physics</a> <a rel="nofollow noopener noreferrer" class="hashtag u-tag u-category" href="https://selfawarepatterns.com/tag/science/" target="_blank">#Science</a>

Hari TulsidasScientists have discovered a discrepancy between the two main concepts of the “arrow of time.” The thermodynamic arrow, which points toward increasing entropy, and the psychological arrow, which aligns with our perception of time moving from past to future, don’t always match up.
