Poems for Pi--March 14 is Pi Day

Various poems and phrases have been employed to encode the decimal expansion of pi. Below are two poems that encode the digits of pi to 14 and 31 digits respectively. Simply count the number of letters in each word of the poem. For example the words in the phrase How I love pi! have three, one, four, and two letters each; while the decimal expansion of pi to the nearest thousandth is 3.142.*A Short Poem*

(14 digits)

How I wish I could recollect

of circle round

the exact relation

Archimede? unwound.

*A Longer Poem*

(31 digits)

Sir, I send a rhyme excelling

In sacred truth and rigid spelling.

Numerical sprites elucidate for me

The lexicons full weight.

If Nature gain,

Who can complain,

Tho' Dr. Johnson fulminate?

The two poems above appeared in the magazine Omni in the mid-seventies.

If you know the source of these poems, please send e-mail.

The great mathematician's name is misspelled. It's Archimedes.

The Pi Webring- a site that has links to 17 Pi web pages and 10 general interest math pages.

A Tribute to Pi- has a good chronology of Pi (in English this time).
