One of my frequent interesting reads is the Quote of the Day #QOTD posted on Twitter by Mathematics & Statistics at St Andrews, @StA_Maths-Stats. A few days ago I found there the following mathy-poetic and thought-provoking quote by Polish mathematician Stanislaw Ulam (1909-1984):
The infinite
we shall do right away.
The finite
may take a little longer.
[Quoted in D MacHale, "Comic Sections" (first published in Dublin 1993)]
