Three Mathematical Limericks by Jonathan Rosenberg (all rights reserved by the author) A mathematician named Haar Proved a fact that is far over par That each group has a measure Designed for your pleasure Whose Lp-spaces help you go far. A mathematician named Euler Was really quite of a toiler He wrote so many books People gave him bad looks Which didn't faze that blind fellow Euler. The zeros of zeta of z Are all predicted to be Lined up in a line And it sure would be fine If the person to prove it were me.
