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
Applied Physics Laboratory was used in 2016 for a demonstration in which a paralyzed man was able to "fist-bump" Barack Obama using signals sent from an implanted brain chip. The limb returned sensory feedback from the arm to the wearer's brain. The APL researches and produces unmanned aerial vehicles for the US military. One of its most recent projects is an unmanned aerial swarm that can be controlled by a single operator on the ground.
