Clausius Quotes & Sayings

So many of the properties of matter, especially when in the gaseous form, can be deduced from the hypothesis that their minute parts are in rapid motion, the velocity increasing with the temperature, that the precise nature of this motion becomes a subject of rational curiosity. Daniel Bernoulli, Herapath, Joule, Kronig, Clausius, &c., have shewn that the relations between pressure, temperature and density in a perfect gas can be explained by supposing the particles move with uniform velocity in straight lines, striking against the sides of the containing vessel and thus producing pressure. — James Clerk Maxwell

Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time. — Rudolf Clausius

We live in the last days, in the cold hearted and self centred world where people like you for what you can give or for what they can get from you. That's the world of today. — Euginia Herlihy

Though it is very important for man as an individual that his religion should be true, that is not the case for society. Society has nothing to fear or hope from another life; what is most important for it is not that all citizens profess the true religion but that they should profess religion. — Alexis De Tocqueville

For me, I love California. I feel like it's my second home in that I moved out by choice at eighteen. It gave me opportunities that I didn't have anywhere else. — Vince Vaughn

Rudolf Clausius coined the word in 1865, in the course of creating a science of thermodynamics. He needed to name a certain quantity that he had discovered - a quantity related to energy, but not energy. — James Gleick

The entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium. — Rudolf Clausius

The total energy of the universe is constant; the total entropy is continually increasing. — Rudolf Clausius

The fundamental laws of the universe which correspond to the two fundamental theorems of the mechanical theory of heat.
1. The energy of the universe is constant.
2. The entropy of the universe tends to a maximum. — Rudolf Clausius

I was led to the conclusion that at the most extreme dilutions all salts would consist of simple conducting molecules. But the conducting molecules are, according to the hypothesis of Clausius and Williamson, dissociated; hence at extreme dilutions all salt molecules are completely disassociated. The degree of dissociation can be simply found on this assumption by taking the ratio of the molecular conductivity of the solution in question to the molecular conductivity at the most extreme dilution. — Svante Arrhenius

It is very desirable to have a word to express the Availability for work of the heat in a given magazine; a term for that possession, the waste of which is called Dissipation. Unfortunately the excellent word Entropy, which Clausius has introduced in this connexion, is applied by him to the negative of the idea we most naturally wish to express. It would only confuse the student if we were to endeavour to invent another term for our purpose. But the necessity for some such term will be obvious from the beautiful examples which follow. And we take the liberty of using the term Entropy in this altered sense ... The entropy of the universe tends continually to zero. — Peter Guthrie Tait

His true monument lies not on the shelves of libraries, but in the thoughts of men, and in the history of more than one science.

{Gibbs's obituary for scientist Rudolf Clausius} — Josiah Willard Gibbs

The older I grow, the more I find myself alone. — Alberto Giacometti

The energy of the universe is constant. — Rudolf Clausius

Sometimes when she thought of Eric, and now more powerfully when she saw him, she felt some achy nostalgia for her old self. For the dauntless, daring soul she used to be. There were certain qualities you possessed carelessly. And you couldn't retrieve them when they were gone. — Ann Brashares

In all cases where work is produced by heat, a quantity of heat proportional to the work done is expended; and inversely, by the expenditure of a like quantity of work, the same amount of heat may be produced. — Rudolf Clausius

Clausius and Darwin cannot both be right. — Roger Caillois

Diana: "I wish I were rich, and I could spend the whole summer at a hotel, eating ice cream and chicken salad."
Anne: "You know something, Diana? We are rich. We have sixteen years to our credit, and we both have wonderful imaginations. We should be as happy as queens."
[gestures to the setting sun]
Anne Shirley: "Look at that. You couldn't enjoy its loveliness more if you had ropes of diamonds. — L.M. Montgomery

The algebraic sum of all the transformations occurring in a cyclical process can only be positive, or, as an extreme case, equal to nothing.
[Statement of the second law of thermodynamics, 1862] — Rudolf Clausius
