Foreword: “Five-Minute Mathematics” in Die Welt xiii
Professor Behrends is a bridge-builder, oﬀering a way across the
moat haunted by the dragons of math anxiety into fortress mathemat-
ics. He has the ability to package mathematical content so skillfully
that there are few traces remaining of arid abstraction. If the status
of mathematics is ﬁnally gradually to rise in the public’s perception,
we need more writers like him, and of course more publications that
will oﬀer forums to these authors.
