Eureka is a publication of The Archimedeans, the Cambridge University Mathematical Society. Its focus is on articles of interest to the society, including problems and puzzles, discussions and humour. The first issue was published in 1939; subsequent publishing frequency has averaged between annual and biannual. Selected articles were published by the university faculty and affiliates, such as Béla Bollobás, John Conway, Paul Dirac, Paul Erdős, Douglas Hofstadter and Ian Stewart. Of the notable mathematical articles, there is an influential paper by Freeman Dyson where he defined the rank of a partition in an effort to prove combinatorially the partition congruences earlier discovered by Srinivasa Ramanujan. In the article, Dyson made a series of conjectures that were all eventually resolved.
