Quotes About Entropy

information is the measure of the number of possible alternatives for something.

The growth of entropy is nothing other than the ubiquitous and familiar natural increase of disorder. This is what Boltzmann understood.

The difference between past and future does not lie in the elementary laws of motion; it does not reside in the deep grammar of nature. It is the natural disordering that leads to gradually less particular, less special situations.

Geçmi? ile gelecek aras?ndaki fark yaln?zca ?s? söz konusu oldu?u zaman vard?r. Gelece?i geçmi?ten ay?ran temel olay, ?s?n?n daha s?cak nesnelerden daha so?uk nesnelere geçmesidir.

Time sits at the center of the tangle of problems raised by the intersection of gravity, quantum mechanics, and thermodynamics.

information is the measure of the number of possible alternatives for something. For example, if I throw a die, it can land on one of six faces.

The difference between past and future, between cause and effect, between memory and hope, between regret and intention . . . in the elementary laws that describe the mechanisms of the world, there is no such difference.

Only where there is heat is there a distinction between past and future.

This reads: "Delta S is always greater than or equal to zero," and we call this "the second principle of thermodynamics

entropy, as Boltzmann fully understood, is nothing other than the number of microscopic states that our blurred vision of the world fails to distinguish.

Carlo Rovelli

Only where there is heat is there a distinction between past and future. Thoughts, for instance, unfold from the past to the future, not vice versa—and, in fact, thinking produces heat in our heads. . . .

We are stories, contained within the twenty complicated centimeters behind our eyes, lines drawn by traces left by the (re)mingling together of things in the world, and oriented toward the direction of increasing entropy, in a rather particular corner of this inmense, chaotic universe.

The origin of time may be similar to that of heat: it comes from averages of many microscopic variables. Let's see this in detail.

It is always heat and only heat that distinguishes the past from the future.

Time is an effect of our overlooking the physical microstates of things. Time is information we don't have. Time is our ignorance.

The difference between past and future only exists when there is heat.

Whenever you consider a phenomenon certifying the passage of time , it is through the production of heat that it does so. There is no preferred direction of time without heat.

The index is retrospective. The crucial alpha, the entropy, the signal modulating that linear advance...comes from knowledge of the entrepreneurial surprises harbored on the edge of the noise.

Once everyone is connected to everyone and everything else, nothing matters anymore. If everyone in the world is your Facebook friend, then why have any Facebook friends at all? We're back where we started. The ultimate complexity is just another entropy.

Wszyscy s? jako? zadowoleni ze swoich miejsc, które im wyznaczy?o przeznaczenie i ?a?cuch genów. Wykonuj? skromnie, co im ka?e Wielka Entropia. A ja obra?am si? na los, na swoje ograniczenie, na Pana Boga. Pragn? czego?, czego nie mog?. Marz? o tym, czego nie b?dzie. Ton? w sze??dziesi?ciu litrach w?asnej truj?cej wody, ja, zdefektowany ssak dwuno?ny.

The difference is that the heat energy we radiate is a high-entropy form of energy, meaning it's disordered. The chemical energy we absorb is a low-entropy form of energy, meaning it's ordered. In effect, we are consuming order and generating disorder; we live by increasing the disorder of the universe. It's only because the universe started in a highly ordered state that we are able to exist at all.

Disorder keeps increasing if things are left to themselves.

The universe was so beautiful it hurt. So very, very beautiful. And yet, at the same time, so full of ugliness. Some born of the inexorable demands of entropy; some born of the cruelty that seemed innate to all sentient beings. And none of it made any sense. It was all glorious, horrible nonsense, fit to inspire both despair and numinosity.
