Eureka 49

Eureka is the journal of the Archimedeans, which is the Cambridge University Mathematical Society, and a Junior Branch of the Mathematical Association. Eureka is published approximately annually, but since it, like the Society, is run entirely by student volunteers, it is impossible to guarantee precise publication dates. The Society also publishes QARCH, a problems journal.
