Tras la lisérgica entrada sobre π que puso Patxi el otro día hay que aplicar el dicho: «Si no puedes con ellos, úneteles». CPI presenta otro enlace en el que la canción American Pie es desfigurada hasta llegar a Mathematical π (π suena «pai» en inglés). Audio On, por favor. Tiene su gracia. Y para los más interesados, la letra con los acordes de guitarra (ya saben, esas super-fiestas en las que una canción sobre π a tiempo puede salvar la velada…). Nota: Si el enlace no funciona (tiene tendencia a dejar de funcionar cuando se descarga muchas veces), pueden escuchar la canción completa aquí:

INTRO: A E F#m A long, long time ago Bm D F#m E Long before the Super Bowl and things like lemonade A E F#m The Hellenic Republic was full of smarts Bm D And a question resting on the Grecian hearts F#m D E Was "What is the circumference of a circle?" F#m Bm But they were set on rational numbers F#m Bm And it ranks among their biggest blunders D A Bm They worked on it for years D E And confirmed one of their biggest fears A E F#m Bm7 E I can't be certain if they cried when irrationality was realized A E F#m But something deep within them died D E7 A D A the day they discovered pi. E They were thinking CHORUS: A D A E Pi, pi, mathematical pi A D A E 3 point 14 15 92 A D A E 65 35 89 7 F#m B7 932384 62 F#m E7 6433832 7 (not rounded) VERSE: A Bm Well this kind of pie is different than most D Bm It hasn't got berries, ain't spread on toast F#m E And that's how it's always been A E F#m We keep extending its decimal places Bm D Pushing our computers through their paces F#m E But we'll never reach the end F#m Bm So why the fascination with F#m Bm A number whose end is just a myth D A B7 Whence the adulation D E7 For mental masturbation A E F#m It might have something to do with the stars Bm D To calculate distances from afar A E F#m But that's just a guess 'bout the way things are D E7 A D A Regarding the precision of pi E7 I am pondering CHORUS: VERSE: A Bm Now I feel that I should mention D Bm Pi is applicable in any dimension F#m E At least as far as I know A E F#m If there were no Pi we'd be missing things Bm D Like marbles and mugs and balls of string F#m B7 E7 And sports such as soccer and curling F#m Bm The orbs in their celestial paths F#m Bm Navigate along elliptical graphs D A B7 Ellipses have pi in them too D E7 Just one side of them has grew A E F#m You can see pi in most everything Bm D It's in Cornell's Electron Storage Ring A E F#m And also in slinkies and other springs D E7 A D A And that's why it's important to know pi E You should memorize CHORUS: OUTRO: A Bm Once one night I had a dream D Bm That pi was gone and I had to scream F#m E Cause all pi things had disappeared (pause) A E F#m Can you imagine a world like that Bm D Circles aren't round and spheres are flat F#m B7 E7 It's the culmination of everything we've feared F#m Bm 'Twas a nightmare of epic proportions F#m Bm One that gave me brain contortions D A B7 Oh wait! I mean contusions D E7 They put me in some institutions A E F#m But then I escaped and now I'm free D E A D A E To sing of the virtue of pi CHORUS:
