Good Morning, It’s PI Day – 3.14.15 9:26:53 (or #3.141592653 for short)

by C. Michael Eliasz-Solomon

PITo the #STEM worker geek in me it is a most auspicious time. Stanczyk wishes to note that it is PI day:

3/14/15  9:26:53 (or perhaps you prefer 3.141592653 for short). I know this is irrational. PI is irrational too. An irrational number that  cannot be expressed exactly as a ratio of two numbers in a fraction.  Try with these fractions: 22/7,      333/106,     355/113,      52163/16604,      103993/33102, and      245850922/78256779

Last year (2014) a guy spent 208 days computing PI to 13,300,000,000,000 digits and then a little over a week to verify its correctness.

Take a circle, any circle. Measure its circumference and its diameter. Now divide the circumference length by the diameter. What do you get? This precise moment!  3/14/15 9:26:53 .   This moment will not occur again for another twelve hours (if you use a twelve hour clock) and then not again for another hundred years. It should have been known 26 centuries BC (when they built the great pyramid) and now its the 21 more times, so this precise moment has occured no more than 47 times since PI ‘s 1st known use.

Happy PI day and Happy Birthday Einstein too!
