Happy Pi Day
I don’t remember everyone making such a fuss about March 14th 30 or 40 years ago, and I was a big mathematics geek. (Yeah, I took every calculus course they offered in college… even ones that didn’t apply to my major or minor. I even took calculus for business majors as an elective. I know… I’m strange.) But, it is kind of fun to see all the creative ways people celebrate this non-holiday.
Isn’t it interesting that we humans made sense of this irrational number which represents the circumference of a single unit diameter circle? Or, another way to put it, it is the ration of the circumference to the diameter.
And, it doesn’t just stop there, and I won’t bore you with all the interesting facts about Pi. If you’re interested in some cool tidbits about Pi, visit Wikipedia’s page here: http://en.wikipedia.org/wiki/Pi
I don’t think it is coincidental that Pi has so many applications in trigonometry and geometry. I believe there is a divine power with infinite knowledge who enlightens people like Newton and others. It isn’t just Pi, the natural logarithm e has interesting properties. For example e, which is approximately 2.718281828 is the number of children a human couple need to bare in order to propagate their family. And, since you can’t have a fraction of a child, those with 2 or less children run the risk of their line dying off, where those with 3 or more will most likely have a line that continues.
Since I brought up e, in the early days of computers, they try to determine the ideal system. They came up with e. Since a fraction wouldn’t work, they decided it would work equally as well if it were binary (base 2) or trinary (or ternary) (base 3). Both technologies began to evolve, but binary stuck. (Note: In a binary computer, there are two states, 1 and 0 often represented by 0 volts and +5 volts. In a trinary computer, there three states -1, 0 and +1, often represented by -5, 0 and +5 volts.) Both are equally efficient.
Both e and Pi are found naturally. It is amazing to me that we discovered the correlation in real life applications, yet, we were not the inventors. They have always existed, we have just learned over the centuries how the impact our lives and how we can learn from having discovered them.
So, go have yourself some Pi e. After all, it is Pie Day.
