In existographies, Stephen Hawking (13 BE-63 AE) (1942-2018 ACM) (IQ:180|#99) (RGM:65|1,350+) (PR:117|65AE / physicist:4) (Norlinger 22:29) (FA:257) (RGA:6|370+) (CR:144) (LH:17) (TL:162|#61) was English astrophysicist, noted for 
In 1965, Hawking completed his PhD thesis, stimulated by research of mathematician Rodger Penrose, and based on Albert Einstein’s 1914 general theory of relativity, which argued that if a star can collapse inwards to form a singularity, coined a “black hole” in 1967 by American physicist John Wheeler, then so to can a singularity explode back outward; thus giving an explanation for the big bang.
Entropy of mind
In 1988, Hawking published A Brief History of Time, which became a laymanized science best-seller.
In 1996, Hawking, in his Illustrated: A Brief History of Time, gave an "entropy of mind" diagram, which he says changes in respect to doing things such as reading a book. Hawking is a key figure in the development of the subject of black hole thermodynamics. in the 1996 "illustrated" edition, he gave his famous "entropy of the mind" vs "entropy of the body" diagram, stating something to the effect that when one reads a book, it works to lower the entropy of the mind, which is off-set by the increase in the "entropy of the body", in accordance with his understanding of the second law, which is order/disorder based, as shown adjacent.
In 2001, Libb Thims was influenced by this diagram, in some way or another, in respect to his newly-formed model that the basic equation for the measure of the spontaneity of an earth-surface bound chemical reaction, whether in a beaker or on a beach, defined as follows:
can be be "expanded", when considering human time scales, e.g. over a 25-year generational period, to the effect that the delta S term (ΔS), representing "change", or specifically a final entropy state SF minus an initial entropy state SI, or the difference in the entropy of a person (or the sum entropy of the mind + body) on year 25 of their existence less the entropy of year one of their existence:
Whereby, when this "initial state" and "final state", entropy of someone on year 25 (S25) as compared to the entropy of someone in year 35 (S35) or year one (S1), which will change depending on whether one "reads a book", as Hawking says, or "robs a bank" or "rakes the backyard", as an alternative examples, these will go into the final calculation of the Gibbs energy change of various existence transforming reactions a person may go through, such as sexual reproduction (which 85% of people transform through); which would render as follows:
In very simplified terms. Hence, e.g., the eight year process, with an a "final" and an "initial" state, of getting a four-year college degree and then a four year medical school degree, will function to decrease the "entropy of the mind" of the person, as Hawking describes things, thus affecting the "spontaneity", as measured by Gibbs energy change, of the reaction, e.g. the spontaneity of a women willingly having sex with the man, in the final years of his medical school degree, as evidenced by the Buss study (1993) adjacent; in other words, the entropy change works to change the spontaneity of various human chemical reactions, in particular love the chemical reaction, in the sense that it is statistically easier to get someone to fall spontaneously in love with another person in possession of a college degree than without.

The following are quotes by Hawking:
- “Cosmology is a kind of religion for intelligent atheists.”
- — Stephen Hawking (c.1962), “Comment to Jane Hawking” 
- “Before we understand science, it is natural believe that god created the universe. But now science offers a more convincing explanation. What I meant, in A Brief History of Time (1988), by the phrase ‘we would know the mind of god’, is we would know everything that god would know, if there were a god. Which there isn’t. I’m an atheist.”
