If ever there was a book that could be classified as prog metal this is it. Set in Bern, Switzerland, in the year 1905, Physicist Alan Lightman’s Einstein’s Dreams explores the literal consequences of hypothetical postulates derived from Albert Einstein’s Special Theory of Relativity and some deep thought about the nature of space and time. The vehicle for this exploration is a series of dreams that occur to a certain youthful patent clerk that take place in the two months leading up to June 30th. The day the journal Annalen der Physik would receive the paradigm-shifting paper. (The third of four he published that year as part of his Annus Mirabilis or “miracle year”.) It’s a quick read, about 140 pages, but that’s all Lightman needed to create myriad of mind bending worlds by modifying the physics of time, space, and entropy.
