# The Eureka archive in now online

The Cambridge University Mathematical Society, *The Archimedeans*, has published a magazine called “Eureka” ( https://archim.org.uk/eureka/ ) since 1939. Here some news by **Adam Atkinson**.

Here is the cover of issue number 46, from 1986. It contains an article by John Conway on “audioactive decay”, a surprisingly detailed analysis of the “look and say sequence” 1, 11, 21, 1211, …

According to the Eureka website, articles by Dirac and Hardy have appeared, and elsewhere I read that there is an article by Freeman Dyson in issue 8, published in 1944.

The appearance of the magazine has changed somewhat since 1986:

My Eureka collection is far from complete:

I didn’t imagine that it ever would be complete. For decades many of the back issues have, fairly obviously, not been for sale. I didn’t even imagine I would ever see some of the earlier issues.

However, I recently learned that a digital archive of Eureka has been created, containing all the issues from 3 to 65, available at https://archim.org.uk/eureka/archive/ – I have of course asked the obvious question and am told they have a source for issues 1 and 2 and hope to put those online soon as well.

I hope that this news is of some interest or use to visitors to Mathematics in Europe.
