			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>Hace más de una semana se celebró el día de Pi o día pi ( Pi Day, en inglés) y alrededor del mundo se celebró este acontecimiento de diversas formas. Algunos preparon Pies de Manzanas, confeccionaron T-shirts con el símbolo de pi (<img src='http://l.wordpress.com/latex.php?latex=%5Cpi&#038;bg=ffffff&#038;fg=333333&#038;s=0' alt='\pi' title='\pi' class='latex' />).</p>
<p style="text-align:justify;"> </p>
<div class="wp-caption aligncenter" style="width: 510px"><img title="Pi t-shirt" src="http://farm1.static.flickr.com/187/421450149_3196c97c5c.jpg?v=0" alt="Pi t-shirt" width="500" height="375" /><p class="wp-caption-text">Pi t-shirt</p></div>
<p style="text-align:justify;">Asimismo, algunos crearon canciones sobre este número tan fascinante. Precisamente este último detalle quiero compartir con todos ustedes.</p>
<p style="text-align:justify;">Encontré una canción muy entretenida que se titula &#8220;Mathematical Pi&#8221; <em>(matemática Pi) </em></p>
<p>Aquí el mp3. de la canción:</p>
<p style="text-align:center;"><span style="text-align:center; display: block;"><a href="http://edualgebra.wordpress.com/2009/03/30/la-cancion-de-pi/"><img src="http://img.youtube.com/vi/qZlyHtSZsYQ/2.jpg" alt="" /></a></span></p>
<p>Aquí la letra de la canción:</p>
<p style="text-align:left;"><span>A long, long time ago,<br />
Long before the Super Bowl and things like lemonade,<br />
The Hellenic Republic was full of smarts,<br />
And a question resting on the Grecian hearts was;<br />
What is the circumference of a circle?&#8221;,<br />
But they were set on rational numbers,<br />
And it ranks among their biggest blunders,<br />
They worked on it for years,<br />
And confirmed one of their biggest fears,<br />
I can&#8217;t be certain if they cried when irrationality was realised,<br />
But something deep within them died,<br />
The day, they discovered, Pi.</span></p>
<p>They were thinking;<br />
Pi, pi, mathematical pi,<br />
3.14 15 92,<br />
65 35 89 7,<br />
932384 62,<br />
6433832 7 (not rounded).</p>
<p>Well this kind of Pi is different than most,<br />
It hasn&#8217;t got berries, ain&#8217;t spread on toast,<br />
And that&#8217;s how it&#8217;s always been,<br />
We keep extending its decimal places,<br />
Pushing our computers through their paces,<br />
But we&#8217;ll never reach the end,<br />
So why the fascination with,<br />
A number whose end is just a myth?<br />
Whence the adulation,<br />
For mental masturbation,<br />
It might have something to do with the stars,<br />
To calculate distances from afar,<br />
But that&#8217;s just a guess &#8217;bout the way things are,<br />
Regarding the precision of Pi,</p>
<p>I am pondering;<br />
Pi, pi, mathematical pi<br />
3.14 15 92<br />
65 35 89 7<br />
932384 62<br />
6433832 7</p>
<p>Now I feel that I should mention,<br />
Pi is applicable in any dimension,<br />
At least as far as I know,<br />
If there were no Pi we&#8217;d be missing things,<br />
Like marbles and mugs and balls of string,<br />
And sports, such as soccer and curling,<br />
The orbs in their celestial paths,<br />
Navigate along elliptical graphs,<br />
Ellipses have pi in them too,<br />
Just one side of them has grew,<br />
You can see pi in most everything,<br />
It&#8217;s in Cornell&#8217;s Electron Storage Ring,<br />
And also in slinkies and other springs,<br />
And that&#8217;s why it&#8217;s important to know pi,</p>
<p>You should memorize,<br />
Pi, pi, mathematical pi,<br />
3.14 15 92,<br />
65 35 89 7,<br />
932384 62,<br />
6433832 7,</p>
<p>Once one night I had a dream,<br />
That pi was gone and I had to scream,<br />
Cause all pi things had disappeared.<br />
Can you imagine a world like that?<br />
Circles aren&#8217;t round and spheres are flat,<br />
It&#8217;s the culmination of everything we&#8217;ve feared,<br />
&#8216;Twas a nightmare of epic proportions,<br />
One that gave me brain contortions,<br />
Oh wait! I mean contusions,<br />
They put me in some institutions,<br />
But then I escaped and now I&#8217;m free!</p>
<p>To sing of the virtue of pi,<br />
Pi, pi, mathematical pi,<br />
3.14 15 92,<br />
65 35 89 7,<br />
932384 62,<br />
6433832 7.</p>
