Cavendish Laboratory
The physics department and research laboratory of the University of Cambridge, established in 1874 and named after Henry Cavendish.
James Clerk Maxwell: Scottish physicist whose work unified electricity, magnetism, and light in Maxwell’s equations. As the laboratory’s first director, he established its research and teaching culture.
Electron: A negatively charged subatomic particle found in atoms and involved in electricity and chemical bonding. Thomson’s Cavendish experiments established the electron as a constituent of atoms.
Kelvin balance: An electrostatic instrument that compares electrical forces to determine voltage or electrical quantities. The instrument exemplifies the precision apparatus associated with early Cavendish experimental work.
Henry Cavendish: Eighteenth-century English natural philosopher known for experiments on electricity, gases, and gravitation. The laboratory bears his name, honoring his influential experimental work.
Clarendon Laboratory: The physics laboratory at the University of Oxford, established in the nineteenth century. It provides Oxford’s institutional counterpart to Cambridge’s Cavendish Laboratory.
Lord Rayleigh: English physicist who explained phenomena including Rayleigh scattering and received the 1904 Nobel Prize in Physics. He led the Cavendish Laboratory after Maxwell and helped discover argon there.
Nuclear model: A model of the atom in which a small, dense, positively charged nucleus is surrounded by electrons. Rutherford’s laboratory research helped establish this picture of atomic structure.
Cavendish experiment: Henry Cavendish’s 1798 torsion-balance experiment measuring the gravitational attraction between masses. Although conducted before the laboratory existed, it supplied the institution’s namesake and experimental heritage.
University of Cambridge: A public research university in Cambridge, England, founded in 1209. The Cavendish was created as Cambridge’s dedicated center for experimental physics.
National Physical Laboratory: The United Kingdom’s national measurement institute, established to develop and maintain measurement standards. Unlike the university-based Cavendish, it is organized around national metrology and standards.
