Quotes About Thermodynamics

If entropy has been steadily increasing since the big bang, then the entropy back at the bang must have been much lower than it is today.

el deterioro de sus cuerpos de que habla la segunda ley de la termodinámica

The elevator shaft was a kind of heat sink. Hot food was cold by the time it arrived. Cold food got colder. No one knew what would happen to ice cream, but it would probably involve some rewriting of the laws of thermodynamics.

The difficult truth is that the basic law of thermodynamics still holds: When we eat more calories than we expend, we gain weight. When we burn more energy through physical activity or exercise than we take in from food and drinks, we lose weight.

Can we reconcile the observed constructiveness of cosmic evolution with the inherent destructiveness of thermodynamics? Specifically how have the magnificent examples of order all around us arisen from chaos?

The thermodynamic properties of electrolyte solutions can be determined from the measurements of the voltage between electrodes reversible to both ions.

The trouble is that man, going back to Freud - and excuse the metaphor - heats up like a light bulb: red hot in the twinkling of an eye and cold again in a flash. The female, on the other hand - and this is pure science - heats up like an iron, slowly, over a low heat, like a tasty stew. But then, once she has heated up, there's no stopping her. Like the steel furnaces in Vizcaya! I weighed up Fermin's thermodynamic theories.

Se supone que el Demonio de Maxwell era un personaje muy hábil, capaz de observar cada molécula y cambiar a su antojo la dirección del movimiento de la misma.

Stored energy had a way of leaking, no matter what was done to stop it. That was another aspect of the all-embracing, irresistible second law of thermodynamics.

The conviction grows in me that we shall discover laws of personality and behavior which are as significant for human progress or human understanding as the law of gravity or the laws of thermodynamics.

The First Law simply states that the change in total energy equals the work performed on, plus the heat supplied to, the system (measured in suitable units).

heat "always shows a tendency to equalize temperature differences and therefore to pass from hotter to colder bodies" [15]. A

if nothing else around it changes, heat cannot pass from a cold body to a hot one......This is the only basic law of physics that distinguishes the past from the future.

All of this, I believe, indicates that in order to grasp the basic grammar of the world, we need to merge three basic ingredients, not just two: not just general relativity and quantum mechanics, but also the theory of heat, that is, statistical mechanics and thermodynamics, which we can also describe as "information theory.

The difference between past and future only exists when there is heat. The fundamental phenomenon that distinguishes the future from the past is the fact that heat passes from things that are hotter to things that are colder.

There is no preferred direction of time without heat.

The difference between past and future exists only when there is heat. The fundamental phenomenon that distinguishes the future from the past is the fact that heat passes from things

The difference between past and future exists only when there is heat. The fundamental phenomenon that distinguishes the future from the past is the fact that heat passes from things that are hotter to things that are colder.

The difference between past and future exists only when there is heat. The fundamental phenomenon that distinguishes the future from the past is the fact that heat passes from things that are hotter to things that are colder. So,

Quantum uncertainty across the horizon of the black hole generates fluctuations of the horizon geometry. But "fluctuations" imply "probability," and probability implies thermodynamics, and therefore temperature. Concealing from us a part of the universe, a black hole makes its quantum fluctuations detectable in the form of heat.

In tutti i casi in cui non viene scambiato calore, infatti, oppure quando il calore scambiato è trascurabile, noi vediamo che il futuro si comporta esattamente come il passato.

The crucial point here is the difference from what happens with falling bodies: a ball may fall, but it can also come back up, by rebounding, for instance. Heat cannot. This is the only basic law of physics that distinguishes the past from the future.

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.

Is?, s?cak nesnelerden so?uk nesnelere mutlak bir yasan?n zorlamas?yla geçmez: Yaln?zca bu yöndeki geçi?i daha yüksek bir olas?l?kla olur. Bunun nedeni iste ?udur: S?cak nesneye ait daha h?zl? bir atomun daha so?uk bir atoma çarpmas? ve enerjisinin biraz?n? b?rakmas? ve bunun tersinin olmamas?, istatistiksel olarak daha yüksek bir olas?l?kt?r.
