Jennifer Coopersmith has written a most welcome
book, the first historically and philosophically motivated full
study since two classics written nearly a half-century ago
[by C. Lanczos; and W. Yourgrau and S. Mandelstam]. This follows her earlier acclaimed book Energy, the Subtle Concept, revised edition, 2015, and is written in the same style, a pleasing combination of qualitative and quantitative arguments…[In The Lazy Universe, she has] succeeded admirably…a fine book.
