Eureka (University of Cambridge magazine)
Eureka is a journal published annually by The Archimedeans, the mathematical society of Cambridge University. It is one of the oldest recreational mathematics publications still in existence. Eureka includes many mathematical articles on a variety of different topics – written by students and mathematicians from all over the world – as well as a short summary of the activities of the society, problem sets, puzzles, artwork and book reviews. Eureka has been published 66 times since 1939, and authors include many famous mathematicians and scientists such as Paul Erdős, Martin Gardner, Douglas Hofstadter, G. H. Hardy, Béla Bollobás, John Conway, Stephen Hawking, Roger Penrose, W. T. Tutte (writing with friends under the pseudonym Blanche Descartes), popular maths writer Ian Stewart, Fields Medallist Timothy Gowers and Nobel laureate Paul Dirac. The journal was formerly distributed free of charge to all current members of the Archimedeans.
