Everyday Einstein – 9.22.10

From Rediscovered Lewis Carroll Puzzles, newly compiled and edited by Edward Wakeling:

“Can you discover the name of Lewis Carroll’s childhood friend, hidden within the verses?

Beloved Pupil! Tamed by thee,

Addish=, Subtrac=, Multiplica=tion,

Divsions, Fractions, Rule of Three,

Attest thy deft manipulation!

Then onward! Let the voice of Fame

From Age to Age repeat thy story,

til thou hast won thyself a name

Exceeding even Euclid’s glory.”
