Mr. Tompkins in Wonderland or Stories of c, G, and h

The eponymous character of Mr Tompkins appears in a series of four books by the physicist George Gamow in which he aims to explain modern scientific theories to a popular audience. This one, 1940. The books are structured as a series of dreams in which Mr Tompkins enters alternate worlds where the physical constants have radically different values from those they have in the real world. This results in the counterintuitive results of the theory of relativity and quantum mechanics becoming obvious in everyday life. Mr Tompkins' adventures begin when he chooses to spend the afternoon of a day's holiday attending a lecture on the theory of relativity. The lecture proves less comprehensible than he had hoped and he drifts off to sleep and enters a dream world in which the speed of light is a mere 30 miles an hour. This becomes apparent to him through the fact that passing cyclists are subject to a noticeable Lorentz-Fitzgerald contraction. Despite this inauspicious beginning to his scientific education, Mr Tompkins becomes acquainted with the Professor delivering the lectures and ultimately marries the Professor's daughter, Maud. Later chapters in the books deal with atomic structure (Mr Tompkins spends time as a conduction electron, returning to consciousness when he is annihilated in an encounter with a positron) and thermodynamics (the Professor expounds an analogy between the second law of thermodynamics and the bias towards the casino in gambling before being confounded by a local reversal of the second law through the intervention of Maxwell's demon who has introduced himself to Maud in one of her dreams).
