Froschmäusekrieg is
german for "war between the frogs and the
mice" from a poem attributed to Homer (Batrachomyomachia), which is a
satire about the pointlessness of war or feuding.
Froschmäusekrieg was used by
Helen Dukas (Einstein's secretary and literary executor) to describe the long and bitter dispute between the School of
Math and the School of Social
Science at the Institute for Advanced Study. A good word to know when facing such a dispute.
