Pi Day

"🎶 e to the x dx dy radical transcendental pi secant cosine tangent sine 3.14159 2.71828 Come on folks let's integrate!!!" ~ Maths Fight Song

Happy March 14th, 3/14, 3.14 Pi(e) Day to all you numberphiles, mathematics majors, statisticians, and math teachers! A kilt in this tartan will have you and your students dancing in circles! Got a favorite transcendental number? The number "pi" is an infinitely repeating mathematical constant, equal to the ratio of a circle‘s circumference to its diameter, approximated as a weaving sett to 3.14159, the digits of which can be seen in the light green widths. The black and greens of this tartan are reminiscent of the colours of early computer display screens and efforts to computationally calculate the digits of pi (currently calculated at 100 trillion digits)! This non-repeating value has been represented by the Greek letter “π” since the mid-18th century though it is also sometimes spelled out as “pi." Today, is a good day to impress your friends by memorizing some of the digits of this irrational number. One mnemonic that can help if you don't have this tartan as visual hint is the quote, ""How I want a drink, alcoholic of course, after the heavy lectures involving quantum mechanics" representing 15 digits (3.14159265358979) with the number letters per word representing the digits. Or if that seems like just too much effort for a busy weekday, your friends may equally impressed with an offering of some apple, cherry, or blueberry pie! Transcendently yum! 🟢 ⚫ 🟢 π π π 🥧 🥧 🥧

A tartan for today's special date, March 14th, also known as Pi Day, for the transcendental number, starting with the digits forming today's date (in the month/day/year system) = 3.14159 ...

Recall that pi is the ratio of a circle’s circumference to its diameter.

By designer Carol A.L. Martin, the "3.14159..." tartan embodies the digits in the numbers of light-colored stripes.

Because pi is an irrational number, it repeats forever. Some mathematicians have made it a challenge to continuously calculate more and more digits of pi.   


The current record for this noble endeavor is 13.3 trillion digits by Alexander Yee and Shigeru Kondo.
