I modi possibili per ricordare le prime N cifre di pi greco sono praticamente illimitati: ecco alcuni di quelli più noti. Come vedete, spesso ricordano Archimede di Siracusa (287-212 a.C.), il primo a spingere il calcolo oltre i primi due decimali, costruendo i poligoni regolari fino a quello di 96 lati.

Circle Digits: A Self-Referential Story
by Michael Keith
In questa ingegnosissima storiella mnemonica, i segni di punteggiatura rappresentano degli zeri, mentre le parole di oltre 9 lettere rappresentano due cifre: per esempio, una parola di 12 cifre sta per le due cifre successive 1 e 2. Tanto di cappello al suo inventore, ma anche a chi riesce a ricordare a memoria tutta la tirata!!!
a time I stood pondering on circle sizes. The large
computer mainframe quietly processed all of its assembly code.
Inside my entire hope lay for figuring out an elusive expansion. Value: pi.
Decimals expected soon. I nervously entered a format procedure. The mainframe
processed the request. Error. I, again entering it, carefully retyped. This iteration gave
zero error printouts in all-success. Intently I waited. Soon, roused by thoughts within me,
appeared narrative mnemonics relating digits to verbiage! The idea appeared to exist but only in
abbreviated fashion-little phrases typically. Pressing on I then resolved, deciding firmly about a
sum of decimals to use-likely around four hundred, presuming the computer code soon halted!
Pondering these ideas, words appealed to me. But a problem of zeros did exist. Pondering more, solution
subsequently appeared. Zero suggests a punctuation element. Very novel! My thoughts were culminated.
No periods, I concluded. All residual marks of punctuation = zeros. First digit expansion answer then came
before me. On examining some problems unhappily arose. That imbecilic bug! The printout I possessed
showed four nine as foremost decimals. Manifestly troubling. Totally every number looked wrong. Repairing
the bug took much effort. A pi mnemonic with letters truly seemed good. Counting of all the letters probably
should suffice. Reaching for a record would be helpful. Consequently, I continued, expecting a good final
answer from computer. First number slowly displayed on the flat screen-3. Good. Trailing digits appar-
ently were right also. Now my memory scheme must probably be implementable. The technique was
chosen, elegant in scheme: by self reference a tale mnemonically helpful was ensured. An able title
suddenly existed-"Circle Digits." Taking pen I began. Words emanated uneasily. I desired more
synonyms. Speedily I found my (alongside me) Thesaurus. Rogets is probably an essential in
doing this, instantly I decided. I wrote and erased more. The Rogets clearly assisted
immensely. My story proceeded (how lovely!) faultlessly. The end, above all,
would soon joyfully overtake. So, this memory helper story is incon-
testably complete. soon I will locate publisher. There a narrative
will I trust immediately appear, producing fame.
Near a Raven
di E. Poe
Comincia da Poe, e tieni conto che anche qui una parola di 14 lettere sta per le cifre successive 1 e 4. Ingegnoso, eh?
Near a Raven
Midnights so dreary, tired and weary.
Perfectly, the intellect remembers: the ghostly fires, a glittering
Ominously, curtains parted (my serenity outsmarted),
Taking little time, briskly addressing something: "Sir," (robustly)
While surrounded by darkness then, I persevered to clearly
Silently, I reinforced, remaining anxious, quite scared, afraid,
Completely disturbed, I said, "Utter, please, what prevails ahead.
Bemused by raven's dissonance, my soul exclaimed, "I seek
My sentiments extremely pained, to perceive an utterance so plain,
Still, the detestable raven just remained, unmoving, on sculptured
The raven's dirge induced alarm - "nevermore" quite wearisome.
Seizing just that moment to sit - closely, carefully, advancing
"Disentangle, nefarious bird! Disengage - I am disturbed!"
Since, to me, that thought was madness, I renounced continuing
" 'Tis a prophet? Wraith? Strange devil? Or the ultimate evil?"
In answer, the raven turned - relentless distress it spurned.
"O, satanic inferno's denizen -- go!", I said boldly, standing
So he sitteth, observing always, perching ominously on these
