An apocryphal story sometimes heard among physicists concerns a toast, proposed by his Cambridge University colleagues, to J. J. Thomson’s discovery of the electron in 1897: “To the electron: may it never be of use to anyone!” That joke reflects a serious conundrum: should science be judged by its usefulness, or by its success at increasing our understanding of nature?

ITHACA, NEW YORK – An apocryphal story sometimes heard among physicists concerns a toast, proposed by his Cambridge University colleagues, to J. J. Thomson’s discovery of the electron in 1897: “To the electron: may it never be of use to anyone!” Pure mathematicians supposedly tell a similar joke about their profession.
