# Everyone’s Favorite Irrational Number

Everyone’s Favorite Irrational Number

For all the Math lovers out there, this upcoming Saturday is Pi day! But not just any ordinary Pi day, not just the 3.14 mind you but this year its 3.1415! As I was researching this topic I was surprised to see how much of the Bible was associated with Pi.

History of Pi

By measuring circular objects, it has always turned out that a circle is a little more than 3 times its width around. In the Old Testament of the Bible (1 Kings 7:23), a circular pool is referred to as being 30 cubits around, and 10 cubits across. The mathematician Archimedes used polygons with many sides to approximate circles and determined that Pi was approximately 22/7. The symbol (Greek letter “π”) was first used in 1706 by William Jones. A ‘p’ was chosen for ‘perimeter’ of circles, and the use of π became popular after it was adopted by the Swiss mathematician Leonhard Euler in 1737. In recent years, Pi has been calculated to over one trillion digits past its decimal. Only 39 digits past the decimal are needed to accurately calculate the spherical volume of our entire universe, but because of Pi’s infinite & patternless nature, it’s a fun challenge to memorize, and to computationally calculate more and more digits.

Pi facts:

• The Guinness record for the most digits of pi memorized belongs to Chao Lu, of China, who recited pi from memory to 67,890 places in 2005, although Akira Haraguchi had been filmed to recite it to 100,000 digits in 2006.
• There is even a Pi language called Pilish: the numbers of letters in successive words match the digits of pi.
• Now I fall, a tired suburban in liquid under the trees, drifting alongside forests simmering red in the twilight over Europe. (“Now” has three letters, “I” has one letter, “fall” has four letters, and so on.)
• The symbol for pi (π) has been used regularly in its mathematical sense only for the past 250 years.
• The Bible alludes to pi in 1 Kings 7:23 where it describes the altar inside Solomon’s temple: “And he made a molten sea of ten cubits from brim to brim . . . and a line of thirty cubits did compass it round about.” These measurements procure the following equation: 333/106 = 3.141509.
