\nToday is American pi day. Using the American convention of representing today's date as 03.14.07, it's easy to see why mathematicians are so excited about today's date, which very much resembles a quick approximation of the value of pi, or 3.14159. (One can only imagine the lack of decorum that must have prevailed back in 1915, when the date was a perfect 03.14.15). Yahoo! News has the details:
"[This is a story] about a curious group of people with an almost religious zeal for a\nmind-numbing string of numbers. Actually one number, made up of a chain\nthat is known — so far — to be more than one trillion digits long. They\nare the acolytes of the church of pi.\n\n
And once a year many of them gather to talk about pi, rhapsodize\nabout it, eat pi-themed foods (actual pie, sure, but so much more),\nhave pi recitation contests and, just maybe, feel a little less\nsheepish about their unusual passion.\n\n
That day falls on Wednesday this year: March 14. Or 3.14. Obviously."

It's one of the most consistent patterns in the unviverse. What causes it?
- Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
- Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
- Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
