Henry Cavendish prefiguring thermodynamics. Theoretical physicist Dietrich Belitz concluded that in this work Cavendish "got the nature of heat essentially right." As Cavendish performed his famous density of the Earth experiment in an outbuilding in the garden of his Clapham Common estate, his neighbours would point out the building and tell their children that it was where the world was weighed. In honour of Henry Cavendish's achievements and due to an endowment granted by Henry's relative William Cavendish, 7th Duke of Devonshire, the University of Cambridge's physics laboratory was named the Cavendish Laboratory by James Clerk Maxwell, the first Cavendish Professor of

Raleigh spent £1500 updating the laboratory, and created a new practical course, revolutionising practical instruction, and in 1882 he allowed women to take the course as well. In his five years as Cavendish Professor, he published 50 papers and expanded the number of students to 48. J. J. Thomson was made Cavendish Professor in 1884 at the age of 28, leading one senior member of the University to comment that "Matters have come to a pretty pass when they elect mere boys Professors." In 1895, a change was made to
