• Grothendieck: the new algebraic geometry by Frans Oort
  This article describes the life and work of the brilliant mathematician Alexander Grothendieck and gives an example of his idiosyncratic approach to mathematical research.
• Arabian astrology and Western European mathematics by Jan Hogendijk
  Jan Hogendijk, a historian of mathematics and specialist in the mathematics and astronomy of medieval islam, tries to answer the question where working with theorems and proofs actually comes from.
• Not all that's gold obeys the ratio by Albert van der Schoot

The Nieuw Archief voor Wiskunde is the quarterly journal of the Royal Dutch Mathematical Society. It is sent to some 1800 subscribers in the Netherlands and abroad. The journal is meant for anyone who is involved with mathematics professionally, as an academic or industrial researcher, student, teacher, journalist, or policymaker. Its goal is to report on developments in mathematics in general and in the Dutch mathematical community in particular.
