Pi Mnemonics

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.


Now I even I
Would celebrate in rhymes unapt
The great immortal Syracusan
Rivaled nevermore
Who in his wondrous lore
Passed on before
Gave men his guidance
How to circles mensurate.
    --Submitted by: A.Q. King

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.


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.
The end.

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.
    Silently pondering volumes extolling all by-now obsolete lore.
During my rather long nap - the weirdest tap!
    An ominous vibrating sound disturbing my chamber's antedoor.
        "This", I whispered quietly, "I ignore".

Perfectly, the intellect remembers: the ghostly fires, a glittering ember.
    Inflamed by lightning's outbursts, windows cast penumbras upon this floor.
Sorrowful, as one mistreated, unhappy thoughts I heeded:
    That inimitable lesson in elegance - Lenore -
        Is delighting, exciting...nevermore.

Ominously, curtains parted (my serenity outsmarted),
    And fear overcame my being - the fear of "forevermore".
Fearful foreboding abided, selfish sentiment confided,
    As I said, "Methinks mysterious traveler knocks afore.
        A man is visiting, of age threescore."

Taking little time, briskly addressing something: "Sir," (robustly)
    "Tell what source originates clamorous noise afore?
Disturbing sleep unkindly, is it you a-tapping, so slyly?
    Why, devil incarnate!--" Here completely unveiled I my antedoor--
        Just darkness, I ascertained - nothing more.

While surrounded by darkness then, I persevered to clearly comprehend.
    I perceived the weirdest dream...of everlasting "nevermores".
Quite, quite, quick nocturnal doubts fled - such relief! - as my intellect said,
    (Desiring, imagining still) that perchance the apparition was uttering a whispered "Lenore".
        This only, as evermore.

Silently, I reinforced, remaining anxious, quite scared, afraid,
    While intrusive tap did then come thrice - O, so stronger than sounded afore.
"Surely" (said silently) "it was the banging, clanging window lattice."
    Glancing out, I quaked, upset by horrors hereinbefore,
        Perceiving: a "nevermore".

Completely disturbed, I said, "Utter, please, what prevails ahead.
    Repose, relief, cessation, or but more dreary 'nevermores'?"
The bird intruded thence - O, irritation ever since! -
    Then sat on Pallas' pallid bust, watching me (I sat not, therefore),
        And stated "nevermores".

Bemused by raven's dissonance, my soul exclaimed, "I seek intelligence;
    Explain thy purpose, or soon cease intoning forlorn 'nevermores'!"
"Nevermores", winged corvus proclaimed - thusly was a raven named?
    Actually maintain a surname, upon Pluvious seashore?
        I heard an oppressive "nevermore".

My sentiments extremely pained, to perceive an utterance so plain,
    Most interested, mystified, a meaning I hoped for.
"Surely," said the raven's watcher, "separate discourse is wiser.
    Therefore, liberation I'll obtain, retreating heretofore -
        Eliminating all the 'nevermores' ".

Still, the detestable raven just remained, unmoving, on sculptured bust.
    Always saying "never" (by a red chamber's door).
A poor, tender heartache maven - a sorrowful bird - a raven!
    O, I wished thoroughly, forthwith, that he'd fly heretofore.
        Still sitting, he recited "nevermores".

The raven's dirge induced alarm - "nevermore" quite wearisome.
    I meditated: "Might its utterances summarize of a calamity before?"
O, a sadness was manifest - a sorrowful cry of unrest;
    "O," I thought sincerely, "it's a melancholy great - furthermore,
        Removing doubt, this explains 'nevermores' ".

Seizing just that moment to sit - closely, carefully, advancing beside it,
    Sinking down, intrigued, where velvet cushion lay afore.
A creature, midnight-black, watched there - it studied my soul, unawares.
    Wherefore, explanations my insight entreated for.
        Silently, I pondered the "nevermores".

"Disentangle, nefarious bird! Disengage - I am disturbed!"
    Intently its eye burned, raising the cry within my core.
"That delectable Lenore - whose velvet pillow this was, heretofore,
    Departed thence, unsettling my consciousness therefore.
        She's returning - that maiden - aye, nevermore."

Since, to me, that thought was madness, I renounced continuing sadness.
    Continuing on, I soundly, adamantly forswore:
"Wretch," (addressing blackbird only) "fly swiftly - emancipate me!"
    "Respite, respite, detestable raven - and discharge me, I implore!"
        A ghostly answer of: "nevermore".

" 'Tis a prophet? Wraith? Strange devil? Or the ultimate evil?"
    "Answer, tempter-sent creature!", I inquired, like before.
"Forlorn, though firmly undaunted, with 'nevermores' quite indoctrinated,
    Is everything depressing, generating great sorrow evermore?
        I am subdued!", I then swore.

In answer, the raven turned - relentless distress it spurned.
    "Comfort, surcease, quiet, silence!" - pleaded I for.
"Will my (abusive raven!) sorrows persist unabated?
    Nevermore Lenore respondeth?", adamantly I encored.
        The appeal was ignored.

"O, satanic inferno's denizen -- go!", I said boldly, standing then.
    "Take henceforth loathsome "nevermores" - O, to an ugly Plutonian shore!
Let nary one expression, O bird, remain still here, replacing mirth.
    Promptly leave and retreat!", I resolutely swore.
        Blackbird's riposte: "nevermore".

So he sitteth, observing always, perching ominously on these doorways.
    Squatting on the stony bust so untroubled, O therefore.
Suffering stark raven's conversings, so I am condemned, subserving,
    To a nightmare cursed, containing miseries galore.
        Thus henceforth, I'll rise (from a darkness, a grave) -- nevermore!
