1. On the place of numerical analysis in the mathematical universe
A long time ago, when younger and rasher mathematicians, we both momentarily har-
boured the ambition that one day, older and wiser, we might write a multivolume treatise
titled “On the Mathematical Foundations of Numerical Analysis”. And then it dawned
that such a creation already exists: it is called ‘a mathematics library’. Indeed, it is al-
most impossible to identify a mathematical theme, no matter how ‘pure’, that has never
influenced numerical reasoning: analysis of all kinds, of course, but also algebra, graph
theory, number theory, probability theory, differential geometry, combinatorial topol-
ogy, category theory . . . The mainspring of numerical analysis is, indeed, the entire
aquifer of mathematics, pure and applied, and this is an enduring attraction of the dis-
cipline. Good luck to those content to spend their entire mathematical existen
