You might know the mnemonic for $\pi$ in the title or even this more elaborated one:

Sir, I bear a rhyme excelling
In mystic force, and magic spelling
Celestial sprites elucidate
All my own striving can't relate
Or locate they who can cogitate
And so finally terminate.
Finis.

Are there any for other than $\pi$? Feel free to create your own! Here's my try for $\gamma$:

"0 Euler Leonhard" $\to 0,58$

Choose your favorite language and feel free to post a riddle...

    $\begingroup$ Doesn't really fall under your category, but this is a pretty cool (and effective!) way of memorizing a lot of $\pi$. $\endgroup$ Jan 22, 2013 at 23:03

Martin Gardner quoted one for $\pi$ which I like:

How I wish a drink, alcoholic of course, after the heavy chapters involving quantum mechanics.

  • $\begingroup$ @amWhy: I am always surprised by the weirdness one encounters at times. I just reread the account about an professor analyzing math terms, then using the analysis to write a bogus paper and it was accepted by a (non) reputable journal. I also knew a professor who used math to write poetry and some of it was actually very good! $\endgroup$

I understand that if you recite Homer's Odyssey and Iliad, you repectively get $\frac{2e^2+3}{3π +1}$ and $2\sqrt{π} + 1$. Easy calculations then give you $π$ and $e$ making all other mnemonics superfluous.
