One of the timeless treasures on my bookshelves is a complete collection of work by Lewis Carroll
(pen name for Charles Lutwidge Dodgson, 1832-1898) -- writer, puzzler,
math guy . . . Here's a poem I found in "Answers to Knot 1" in A Tangled Tale. (The problem, Knot 1, is stated below the poem.)
from A Tangled Tale a response (by authors named below) to a puzzle posed by Lewis Carroll
The elder and the younger knight
They sallied forth at three;
How far they went on level ground
It matters not to me;
What time they reached the foot of hill,
When they began to mount,
Are problems which I hold to be
Of very small account.
