French physician-chemist Etienne Geoffroy’s 1718 affinity table, culled from Isaac Newton's "Query 31", the first reaction prediction device; the forerunner to prediction base on free energy, as embodied in 20th century free energy tables. |
“James Thomson, one of the early pioneers of physical chemistry, was able, by an implicit denial of Carnot’s assumption, to predict and prove that the freezing point of water would be lowered by pressure.”
“By means of chemical thermodynamics the physical chemist can indeed, without leaving the ‘cabinet’, predict the course of many chemical reactions.”
“That a body which is united to another, for instance a solvent which has penetrated a metal, should leave it to go and unite with another which is presented to it, is a thing of which the possibility would not have been guessed by the most subtle of philosophers, and of which the explanation is still today not too easy for them. In the end, leaving as unknown that which is unknown, and keeping to certain facts, all the experiments of chemistry prove that a particular body has more disposition to unite with one body than another, and that this disposition has different degrees. This table becomes sort of prophetic, for if substances are mixed together, it can foretell the effect and result of the mixture, because one will see form their different relations what ought to be, so to speak, the issue of the combat.”
“The emphasis is on their usefulness in summarizing chemical facts in an easily memorized form and enabling the user to predict the course of a reaction than on their theoretical implications.”

“These results are interesting, as they show us how we might be able to foresee whether two given states of a substance of the same pressure and temperature, can exist in contact.”
“Now, if we had carried it from a state of liquidity to a state of gas of the same pressure and temperature, making the proper measurements in the process, we should be able to foretell what would occur if these two states of the substance should be brought together—whether evaporation would take place, or condensation, or whether they would remain unchanged in contact—although we had never seen the phenomenon of the coexistence of these two states, or of any of the two states of this substance.”
“Since every chemical process, like every process of nature, can only advance without the introduction of external energy only in the sense in which it can perform work; and since also for a measure of the chemical affinity, we must presuppose the absolute condition, that every process must complete itself in the sense of the affinity—on this basis we me may without suspicion regard the maximal external work of a chemical process (i.e. the change of free energy), as the measure of affinity. Therefore the clearly defined problem of thermo-chemistry is to measure the amounts of the changes of free energy associated with chemical processes, with the greatest accuracy possible … when this problem shall be solved, then it will be possible to predict whether or not a reaction can complete itself under the respective conditions. All reactions advance only in the sense of a diminution of free energy, i.e. only in the sense of the affinity.”
Diagram showing that the direction of natural change is determined, according to Gibbs, such that the variation δ of the free energy G, produced by any variations in the state of the parts of the body, tends over time to decrease, being equal to zero at equilibrium; hence if a body is in state a then one can predict that it will evolve to state b over time, in that state b satisfies the condition of most stable equilibrium. |
“The most important contribution to the subject of predicting the course of a chemical reaction from a few characteristic constants (after the ill-starred attempt of Berthelot).”
Gfinal – Ginitial < 0
ΔG < 0 | Criterion for spontaneous reaction
“The study of free energy affords the only true measure of chemical affinity, and although, when the free energies of all the substances involved in a given reaction are known, it may still be impossible to predict the rate of reaction, it will be possible to state in advance in what direction and to what extent the process can ultimately occur.”

“It is a happy thought that certain lovely combinations are foreordained, and that these human atoms often meet their mates.”
“Statesmen of this and other nations … have embarked upon grandiose undertakings where on physical grounds failure was predictable, and … failure meant that … people perished in vain.”
“The British and French invasion of Egypt in 1956 would never have occurred if the Eden government had properly appreciated the role of Newtonian mechanics in American history. Any student of social physics could have warned the British that the tradition of this Republic recognizes the existence of principle separate from any given set of circumstances.”
See main: History thermodynamicsIn 1952, English physicist C.G. Darwin argued, in his book The Next Million Years, that (a) humans are molecules, which he defined as "human molecules", and (b) that statistical thermodynamics or rather statistical thermodynamics could be used to "predict" the next million years of human evolution, a rather bold speculation. [3]
“Present a theory of social organization and the means to develop the machinery of historical prediction.”

See main: Business thermodynamicsIn the 2004 book The Entropy Vector, American engineers Robert Handscombe and Eann Patterson argue that business practice can be facilitated by utilizing entropy logic in operations. In their preface, however, the state that the second law will not be able to play a role in prediction: [10]
“The second law of thermodynamics on its own will not explain management behavior and would not be able to predict ‘what happens next’ by applying it.”
“Social Thermodynamics Applied Research is the pioneer and world’s leader in the application of social thermodynamics universal laws to real business needs, providing public and private companies with a whole new scientific methodology, not only to model their networks, better understand their user’s roles and influence but, for the first time, to predict, under a non-empirical approach, their future behavior and interactions.”
The circa 1995 "Thims thought experiment", according to which American chemical engineering student Libb Thims conceptualized his top 19 marriage-potential girlfriends as each having a reaction "potential" quantified by the Lewis inequality: ΔG < 0, analogous to what Goethe conceptualized in 1796 via affinities (see: Goethe-Helmholtz equation: A = -ΔG), according to which the discerning human chemist should theoretically be able to "predict" the most-favored human chemical reaction (see: HCR theory) of a given set of potential reactions. |
“Whether two molecules will bind is [completely] determined by the free energy change (ΔG) of the interaction, composed of both enthalpic and entropic terms.”
“Whether two people [human molecules] will bind is [completely] determined by the free energy change (ΔG) of the interaction, composed of both enthalpic and entropic terms.”

“Something like a second law of thermodynamics seems to function in marriage—that is, when marital distress exists, things usually deteriorate (entropy increases).”
Generic drug-receptor reaction coordinate: showing the decrease in Gibbs free energy of the extent of a spontaneous reaction, meaning that the two reactants have a large positive affinity (graphical depiction of reaction prediction). [8] |
“That chemical reactions proceed spontaneously only when the change in a quantity termed the ‘free energy’ is negative for the reaction as written, and that spontaneity can be predicted using this construct, is widely known and gives thermodynamics a pragmatic utility that extends to an applied science such as pharmacology.”
“Desire may or may not be a form of energy. In any case it is certain that a mechanical interpretation cannot help to predict the choices of people.”
“Indeed, what is student heat [see: social heat ]? Is it anything like teen spirit? Or is it, or so I gather, a factor of compression and agitation of people in crowds? And is it quantifiable? It just might be. But why would any of that be important or interesting? Perhaps it might even factor into human movement patterns for building designs in situationist applied unitary urbanism. But any of that doesn't validate or even connect application to sociology or politics.”
The opening section to Irish biochemistry student Ryan Grannell's 2011 blog entry “The Predictions of Human Chemistry”, in which he attempt to argue that human chemistry is not a science because it cannot make predictions and hence is not falsifiable. [16] |
“Regarding your question ‘why would any of that be important or interesting?’, from my point of view (similar to C.G. Darwin), is that of prediction: someone, 200-300 years from now, will be able to predict whether or not any given human chemical reaction will occur, e.g. divorce or 50-years of happy marriage, based on calculated measures of energy and entropy, just as is done with smaller chemical reactions. In other words, in the near future (not likely in our lifetime), people will be able to choose mates intelligently (20-30% rate of divorce at the 15-year mark), rather than willy-nilly (43% divorce rate at the 15-year mark, the current rate).”
“In order to verify Thims theories—that thermodynamic equations describe and predict aspects of human relationships—we will need evidence that they are falsifiable, predictive, and have evidence in favor of them.”
“Free energy tables can be used to predict what reactions are favorable; I’ve used them myself on various occasions in my physical chemistry practicals.”

“To foresee or to guide the affinities of each several molecule would be for the physicist as great a step in advance as it would be for the registrar-general could he foresee or guide every impulse to wedlock in the United Kingdom.”— Frederic Myers (1896), Human Personality and its Survival of Bodily Death

“Carlyle and the others contend that the knowledge of every act and thought of every individual of a given time must be clearly analyzed, and their permutations understood in order to write history. But by the same token we would never be able to understand the time in which we write. Is a metallurgist in a steel mill debarred from understanding the nature of the processes he himself starts, regulates and controls because he cannot give a graphic chart depicting the actions of ever electron of every atom of all the materials he works with, and therefore cannot predict the end results of his operations? But we have gone over this ground before.”— Morris Zucker (1945), Historical Field Theory [24]
“In general, an object in a given force field will, of necessity, behave in a calculable and predictable way. For any object, whether a stone, a plant, or a human society, force means movement.”— Mehdi Bazargan (c.1980), note on Thermodynamics of Humans [21]
“It’s no mystery why economics is called the dismal science. With most sciences, experts make pretty accurate predictions. Mix two known chemicals, and a chemist can tell you ahead of time what you’ll get. Ask an astronomer when the next solar eclipse will be, and you’ll get the date, time, and best viewing locations, even if the eclipse won’t occur for decades. But mix people with money, and you generally get madness. No economist really has any idea when you’ll see the next total eclipse of the stock market.”— Tom Siegfried (2006), A Beautiful Math: John Nash, Game Theory, and the Modern Quest for a Code of Nature [25]
“When a chemist predicts how molecules will react in a test tube, the molecules are oblivious. They do what they do the same way whether a chemist correctly predicts it or not. But in the social sciences, people display much more independence than molecules do. In particular, if people known what you’re predicting you will do, they might do something else just to annoy you.”— Tom Siegfried (2006), A Beautiful Math: John Nash, Game Theory, and the Modern Quest for a Code of Nature [25]
