Celebrate International Pi Day with Maronda Homes

3.14, March 14, 3/14

Everybody remembers St.Patrick’s day is right around the corner, but for those in the mathematical world, let’s celebrate Pi Day! Almost everyone knows pi, (the ratio of the circumference of a circle to its diameter), but there is much more to this famous number!

Pi’s evolution

Around 2000 B.C., Babylonians established the constant circle ratio as 3 1/8 or 3.125. The ancient Egyptians arrived at a slightly different value of 3 1/7 or 3.143.

One of the earliest known records of pi was written by an Egyptian scribe named Ahmes (c. 1650 B.C.) on what is now known as the Rhind Papyrus. He was off by less than 1% of the modern approximation of pi (3.141592).

Plato (427-348 B.C.) supposedly obtained for his day a fairly accurate value for pi: √2 + √3 = 3.146.

The father of calculus (meaning “pebble used in counting,” from calx or “limestone”), Isaac Newton, calculated pi to at least 16 decimal places.

William Jones (1675-1749) introduced the symbol “π” in the 1706, and it was later popularized by Leonhard Euler (1707-1783) in 1737.

Pi is a day of celebration. 

Pi Day is Albert Einstein’s birthday, along with the birthdays of Apollo 8 Commander Frank Borman, Astronomer Giovanni Schiaparelli, and last-man-on-the-moon Gene Cernan.

Pi is even hard for your computer.

Considered a “digital cardiogram.” The record for calculating pi, as of 2010, is to 5 trillion digits.

Pi’s numbers

The first million decimal places of pi consist of 99,959 zeros, 99,758 ones, 100,026 twos, 100,229 threes, 100,230 fours, 100,359 fives, 99,548 sixes, 99,800 sevens, 99,985 eights and 100,106 nines.

At position 763 there are six nines in a row, which is known as the Feynman Point.^

The fraction 22/7 is a well-used number for Pi. It is accurate to 0.04025%.^

The square root of 9.869604401 is approximately Pi.^

The symbol pi

In the Greek alphabet, pi (piwas) is the 16th letter. In the English alphabet, p is also the 16th letter.
