Pie day and Albert Einstein

Today ladies and gentlemen, is Pi day :). Since its discovery back in Babylonian times, it has remained an iconic symbol in math. Pi derives from the ratio of a circle's circumference over its diameter. The Babylonians thought that the ratio was just three, but we know today that Pi is a three with an infinite amount of integers after its decimal point. We just use the convention 3.14 to simplify things. Now why is today Pi day? Because today's date is 3/14/12!  Now why is Pi called pie? lol because of its orientation when you reverse 3.14. Look at the picture below to see what I mean.




Apart from being pie day, its also Albert Einstein's birthday!!! Happy B-DAY Mr. Einstein. Your contributions to the world of science will never be forgotten :)  

 So below me will be some interesting videos on Pi. This post was just a quick post to celebrate todays two important events. Hope you have a good day and eat a piece of pie!!! >:)

    I did not know that pi-day is also Einstein's birthday! This means that he is now 133 years old!

    Regarding your general post though, I think that the videos should be the supplement to your writing, and not the other way around.

    Interesting post though Raul!

    Raul, how do we know for sure that Pi has an infinite amount of decimal places? Could it be that Pi goes to 9999 trillion ^ 9999 trillion decimal places, and then stops? Also, do you know about tau, which is defined as 2*pi? It is interesting, because MIT released their decisions this year 3/14/12 at 6:28 PM, aka Pi Day, Tau PM.

    While I agree with Shiaki that the videos should support the text, I find that you tend to do that, with this post being the exception. I noticed that 3-14 was pi day, but I had not known that it was also Einstein's birthday. Sadly, I had no pie that day :(.
