Biography
He founded the scientific field of social energetics, which was later expanded on by Frederick Soddy in his book The Role of Money.

He was inspired by reading Henry George to investigate sociology. He came to the conclusion that the same mathematics and reasoning applied equally to entropy, energy and thermodynamics in steam boilers as well as in the social body.
