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
Institute of Physics the UK. This is the Lab in a Lorry, a mobile laboratory in a large articulated truck. This has three small laboratories where schoolchildren can try out various hands-on experiments, using physics equipment not usually available in the average school laboratory. Sponsorship is provided by EDF Energy and support from the British Science Association. IOP runs the Stimulating Physics Network, aimed at increasing the uptake of physics at A-level, and administers teacher-training scholarships funded by the Department for Education. The institute is also interested in the ethical impact of physics, as is witnessed though the Physics and Ethics Education Project.
