Robert Hanlon In existographies, Robert T. Hanlon (c.1957-) is an American chemical engineer, noted for []

In 2020, Hanlon, in his Block by Block: the Historical and Theoretical Foundations of Thermodynamics, attempted to present thermodynamics using an illustrative, historical, and physical-conceptual style.

Hanlon, in his Block by Block, breaks up his text with timeline-like flow-style illustrative diagrams, with artwork by Carly Sanker, of discoveries and key points related to various core thermodynamical concepts, such as big bang and quantum mechanics; the following is his take on atomic theory, showing: Democritus (c.400BC), Robert Boyle (17th century), Isaac Newton (1687), Antoine Lavoisier (18th century), John Dalton (19th century), Rudolf Clausius and James Maxwell (1855-1860s), on the kinetic theory of gases, James Maxwell and Ludwig Boltzmann, on statistical mechanics, Einstein (1905) on Browning motion, William Crookes (1870s) on cathode rays, Joseph Thomson (1890s), Marie Curie and Pierre Curie (1990s) on radioactivity, Robert Millikan (1913), Ernest Rutherford (c.1910), Henri Becquerel (1896), James Chadwick (1932), Otto Hahn, Lise Meitner, and Fritz Strassman (1938) on splitting the uranium atom, Ernest Rutherford and Hideki Yukawa (1935) on the nature of the nuclear force or “strong nuclear force”, Enrico Fermi (1930s) on the weak nuclear force, James Maxwell (1873) on the electromagnetic force, and Newton (1968) on the gravitational force (or gravitation).

Atomic theory (Hanlon, 2020)

These diagrams, to note, are similar to Bernard Porter’s 1939 Map of Physics.

Of note, Hanlon devotes his final chapter 43 “Shannon: Entropy and Information Theory”, in a blindly ignorant (see: Shannon bandwagon; entropy pied piper; open sesame; thermodynamic information fallacy; information entropy quotes) attempt to sell bits as joules per degrees kelvin. [2]

In 1985, Hanlon completed his PhD in chemical engineering at MIT with a dissertation on “Realised Catalyst characterization and secondary reaction effects in iron-catalyzed Fischer-Tropsch synthesis” (Ѻ) In 2020, Hanlon was a senior lecturer in the school of chemical engineering practice at MIT.

Quotes | Employed
The following are quotes employed by Hanlon:

“Suppose a piston moves inward, so that the atoms are slowly compressed into a smaller space. What happens when an atom hits the moving piston? Evidently it picks up speed from the collision. You can try it by bouncing a ping-pong ball from a forward-moving paddle, for example, and you will find that it comes off with more speed than that with which it struck (Special example: V an atom happens to be standing still and the piston his it, it will certainly move.) So the atoms are ‘hotter’ when they come away from the piston than they were before they struck it. Therefore, all the atoms which are in the vessel will have picked up speed. This means that when we compress a gas slowly, the temperature of the gas increases. So, under slow compression, a gas will increase in temperature, and under slow expansion it will decrease in temperature.”
Richard Feynman (1963), Lectures on Physics, Volume One (pgs. 1-4); cited by Robert Hanlon (2020) in his Block by Block (xiii) as an explanation of adiabatic compression on a fundamental level [1]

“I tried reading Gibbs and couldn’t get past the third page.”
— Anon (c.2000), comment of PhD student to Robert Hanlon [1]

Quotes | By
The following are quotes by Hanlon:

“Clausius’ 1850 equation: U = Q – AW, is defined such that Q quantifies the heat ‘gained by the system’ (positive value), while W quantifies the ‘work done by the system’ (positive value), such that a system gains energy for positive Q and loses energy for positive W (by doing work).”
