MISCELLANEA II
Mnemonics
Mnemonics Reports
[General]
Some of you may be familiar with the sentence: How I want a drink, alcoholic
of course, after the heavy lectures involving quantum mechanics! The number
of letters in each word represents successive digits of pi:
3.14159265358979.
Over the years, pi enthusiasts have created mnemonic devices for encoding pi
in just about any language you can imagine -- from ancient Greek to modern
Icelandic. These sentences, poems, miniature dramas, comic episodes, and so
forth reflect not only the digits of pi but also the considerable ingenuity
of their authors. Even going beyond the 31st decimal digit requires invoking
some new rule -- such as using 10-letter words -- to encode the zeros of pi.

[Chinese]
I do recall there was a poem written in Shanghai dialect which gives the
first 100 digits of pi.
From: Hongyuan Zha
[German]
Johann A. Sajdowski aus Frankfurt hat, wie er schreibt, einen Text verfaßt,
der als Hymnus an die Natur sogar die ersten 500 000 Stellen von pi wiedergibt.
Dewdney (de), p. 56

There is a Japanese song which gives the first 50 digits of pi,
and used to be taught to Japanese school children.
From: Mike Keane.
[Polish]
I seem to remember that Ode to Mnemosine was about 40 words.
From: Marek Kirejczyk
Editor's Note: Cf. Polish #4
[Slovak]
A poem in Slovak allows to write down Pi on more than 50 digits.
It starts as follows:
(3), o boze o dobry ....
/O'h God o'h good .../

To those interested in mnemonics:
A phD thesis by Robert Alan Hrees with title "An Edited History of
Mnemonics from Antiquity to 1985: Establishing a Foundation for
Mnemonic-based Pedagogy with Particular Emphasis on Mathematics" was
presented in Indiana University in 1985. It is a 2485 pages , in 15
volumes, thesis. It contains practically everything one wants to know
about mnemonics.

[Pi and e mnemonics in several languages]
In one of issues of "Scientific American" (1988?) was a report about
a competition for the longest poem about Pi or e. They gathered such
poems in 101 languages.

Dutch Pi Mnemonics
It seems, that Simon Stevin (mathematician, military architect
and private secretary of the Dutch Stadhouder Maurits in the
end 16th - beginning 17th century) already has composed a long
mnemonic verse for pi and that Christiaan Huygens made one too.
From: Pieter de Groen
Persian Pi Mnemonic
The book (= Struik) also mentions the Persian astronomer / mathematician
Jamsjid al-Kasji (around 1425), Samarkand, who supposedly approximated
pi in 17 decimals and 8 sexagesimals, and also made a mnemonic to it.
From: Joop van den Eijnde
Mnemonics for the Prime Factors of Fermat Numbers
John Pollard is an English mathematician. His main interest is in
factoring big numbers into their prime factors. He has composed
several mnemonics for the prime factors of the Fermat numbers.

A. C. Aitken
New Zealand's greatest mathematician A. C. Aitken (1895-1967) had a
phenomenal memory. Even when old and sick, he found it easy to memorize
Pi to 2000 places ("by the rhythm!"). He invited people to recite digits from
Pi, going forwards or backwards from anywhere in those 2000 places; and
after they had recited about 10 digits he would continue from there!

boyfriend to finish getting math help after school.
