More Problems

*Whatever the details of the matter, it finds
me too absorbed by numerous
occupations for me to be able to devote my attention to it immediately.*

―John Wallis, upon hearing about a problem posed by Fermat in 1657

To help
readers experience first-hand the excitement, frustration, and joy of working
on a challenging numerical problem, we have included in the book a selection of 22 problems in the same style as
Trefethen's 10.

If you solve
one of these and wish to share your solution, we will be happy to receive it.
