About the cover
The English mathematician Alan Turing was born on 23 June 1912 and died tragically aged only 41, yet his influence is still felt in many fields. In this issue marking the centenary of Turings birth, Nature hails him as one of the top scientific minds of all time (see pages 440 and 441). Computer specialists and those working in fields that have exploited computer science — including Sydney Brenner (page 461) and Henry Markram (page 456) — explain some aspects of this remarkable legacy.
