Soddy, Frederick
English physical chemist who pioneered research into atomic disintegration and coined the term isotope. He was awarded the Nobel Prize for Chemistry in 1921 for investigating the origin and nature of isotopes.
The displacement law, introduced by Soddy in 1913, explains the changes in atomic mass and atomic number for all the radioactive intermediates in the decay processes.
After his chemical discoveries, Soddy spent some 40 years developing a theory of ‘energy economics’, which he called ‘Cartesian economics’. He argued for the abolition of debt and compound interest, the nationalization of credit, and a new theory of value based on the quantity of energy contained in a thing.
