As more and more hadrons were discovered it became clear that they were not all elementary particles. This theoretical quandary was addressed independently in 1963 by two. They proposed that all known hadrons were composite particles i. e. hadrons were each made up of a cluster of two or more particles. While zweig called the particles aces , gell-mann light-heartedly called them quarks from the phrase three quarks for muster mark in james joyce"s novel finnegans. Wake. (gell-mann and other physicists, along with some high school physics teachers, mistakenly believe they have a sense of humour. ) To account for every hadron known at the time, gell-mann and zweig proposed the following quark properties: Quarks interact primarily via the strong nuclear force. There are three varieties, or flavours, of quarks and antiquarks.
