 Living Things Renew Themselves

Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued a...

 The Problem of Energy

As a child, I read Friday by Robert A Heinlein, which portrayed a future in which energy needs are addressed by energy storage devices called "Shipstones", which are described as a way to pack more kilowatt-hours into a smaller space and a smaller mass than any other engineer had ever dreamed of. To call it an "improved storage battery" (as some early accounts did) is like calling an H-bomb an "improved firecracker." In the novel, the Shipstone's eponymous inventor realised "that the problem...

Isn't that is isn't plentiful. The sky is raining energy. It's that we have to collect it into buckets for use.

These are partial direct quotes, the direct quote is from a hacker news comment.

 Life is "Enclaves" in a Whirlpool of Chaos

THE FOLLOWING IS QUOTED FROM BERGAN EVANS ON NORBERT WEINER, NUCLEAR PHYSICIST The second concept Wiener has to establish is that of entropy. Probability is a mathematical concept, coming from statistics. Entropy comes from physics. It is the assertion-- established logically and experimentally-- that the universe, by its nature, is "running down", moving toward a state of inert uniformity devoid of form, matter, hierarchy or differentiation. That is, in any given situation, less organizat...

 Partially Diminished Fraction of Ecosystems

Do you know the PDF of your shampoo? A PDF refers to a “partially diminished fraction” of an ecosystem, and if your shampoo contains palm oil cultivated on clear-cut jungle in Borneo, say, that value will be high. How about your shampoo’s DALY? This measure comes from public health: “disability-adjusted life years,” or the amount of one’s life that will be lost to a disabling disease because of, say, a lifetime’s cumulative exposure to a given industrial chemical. So if your fav...

 Intelligence Arises out of a Need to Maximize Entropy

The researchers developed a software engine, called Entropica, and gave it models of a number of situations in which it could demonstrate behaviors that greatly resemble intelligence. They patterned many of these exercises after classic animal intelligence tests. [...] "It actually self-determines what its own objective is," said Wissner-Gross. "This [artificial intelligence] does not require the explicit specification of a goal, unlike essentially any other [artificial intelligence]." ...

The more entropy, the more possibilities. Intelligence therefore seeks to maximize "future histories" in order to keep the number of possibilities maximized.

 Entropy as a Purpose in Life

To the best of our knowledge, these tool use puzzle and social cooperation puzzle results represent the rst successful completion of such standard animal cognition tests using only a simple physical process. The remarkable spontaneous emergence of these sophisticated behaviors from such a simple physical process suggests that causal entropic forces might be used as the basis for a general—and potentially universal—thermodynamic model for adaptive behavior. Namely, adaptive behavior might ...

Researchers have created an AI that self-directs itself into activities like balancing a ball on a stick or buying stocks low and selling high by simply programming it with the desire to maximize the "future histories" available to it (ie. if the ball drops or the AI runs out of money, then the possible futures are reduced to one in the simulation). This suggests a thermodynamic relationship between intelligence and disorder; that we might seek to maximize the entropy in our lives by staying alive, making money, getting educated, or otherwise increase the number of future histories available to us.

 Intelligence as a Response to Entropy

Recent advances in fields ranging from cosmology to computer science have hinted at a possible deep connection between intelligence and entropy maximization. In cosmology, the causal entropic principle for anthropic selection has used the maximization of entropy production in causally connected space-time regions as a thermodynamic proxy for intelligent observer concentrations in the prediction of cosmological parameters [1]. In geoscience, entropy production maximization has been proposed a...

Researchers create an AI that seeks to maximize its potential future histories and therefore tackles goals like playing the stockmarket and balancing balls on sticks because to let the money run out or the ball drop would reduce its potential future histories. Intelligence seeks to maximize entropy.

 Life Works Against the Tide of Entropy

The harsh, demystifying light of science has left the modern biologist with one last miracle, a miracle of organization. Somehow, back in the planet's youth, molecules organized themselves into a structure that could reproduce itself. Dust quickened, and into an inanimate world came animation. All the rest has followed, the flight of the pelican, the fragrance of a baby's skin, the songs of wolf and whale. These latter developments are relatively recent and we know in a general way how they c...

 Life Feeds on Negative Entropy

[A living organism] ... feeds upon negative entropy ... Thus the device by which an organism maintains itself stationary at a fairly high level of orderliness (= fairly low level of entropy) really consists in continually sucking orderliness from its environment.

 Evolution and Entropy are Irreversible

Evolution in the biosphere is therefore a necessarily irreversible process defining a direction in time; a direction which is the same as that enjoined by the law of increasing entropy, that is to say, the second law of thermodynamics. This is far more than a mere comparison: the second law is founded upon considerations identical to those which establish the irreversibility of evolution. Indeed, it is legitimate to view the irreversibility of evolution as an expression of the second law in t...
