Happy Pi Day

This is a celebration of the mysterious, mathematical constant that is so important in describing a circle – and therefore has applications to many branches of mathematics such as trigonometry and calculus.

Enjoy Pi today – I am going to have Key Lime Pi!

What am I reading?

The Man of Numbers by Keith Devlin.  This is the story of Leonardo of Pisa, now known as Fibonacci, who essentially invented modern arithmetic.  He took number out of the context of merely keeping track of things and set the stage for fields such as technology, design, and commerce to develop and prosper

“The change in society brought about by the teaching of modern arithmetic was so pervasive and all-powerful that within a few generations people simply took it for granted. There was no longer any recognition of the magnitude of the revolution that took the subject from an obscure object of scholarly interest to an everyday mental tool. Compared with Copernicus’s conclusions about the position of Earth in the solar system and Galileo’s discovery of the pendulum as a basis for telling time, Leonardo’s showing people how to multiply 193 by 27 simply lacks drama.

Remember the Powers of Ten video? This is a similar concept, but explores the Fibonacci Sequence in nature:

I found this on Brain Pickings as I noodling around following links for the upcoming transit of Venus on June 5-6.

What day did I miss mentioning?

March 21, 2012

Blast! March 14 was Pi Day and I missed it!  Granted, I was busy pillaging that day, but, no excuse.

This is not to be confused with National Pie Day, which is January 23, or whenever I choose to put it on the calendar.

Pi Day, however, is defined by the Pi Day website as:

Pi, Greek letter (π), is the symbol for the ratio of the circumference of a circle to its diameter. Pi Day is celebrated by math enthusiasts around the world on March 14th. Pi = 3.1415926535…

With the use of computers, Pi has been calculated to over 1 trillion digits past the decimal. Pi is an irrational and transcendental number meaning it will continue infinitely without repeating. The symbol for pi was first used in 1706 by William Jones, but was popular after it was adopted by the Swiss mathematician Leonhard Euler in 1737.

Pi is an irrational number and there is no getting a-round it.  Sorry.
