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
Princeton Plasma Physics Laboratory science, solar physics, chemistry, and manufacturing. In 2015, the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) completed the National Spherical Torus Experiment Upgrade (NSTX-U) that makes it the most powerful experimental fusion facility, or tokamak, of its type in the world. Experiments will test the ability of the upgraded spherical facility to maintain a high-performance plasma under conditions of extreme heat and power. Results could strongly influence the design of future fusion reactors. In 1961 Gottlieb became the first director of the renamed Princeton Plasma Physics Laboratory.
