From Wikipedia, the free encyclopedia:The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi".
And today, math geeks everywhere are excited – a perfect Pi (π) date out to four decimal places – 03/14/15 - won’t happen again for another hundred years. Oh, and at 9:23 and 56 seconds, you can go out to nine digits!
"Pi has held an almost mystical quality to humans throughout time," Smithsonian Magazine explains. "Its unspoken presence can be felt in the circular ruins of Stonehenge, in the vaulted ceilings of domed Roman temples and in the celestial spheres of Plato and Ptolemy."
Of course, there are Pi quilts! Check out this one by Cheryl at her blog “Meadow Mist Designs - Engineer By Day, Quilter By Night”:
Cheryl’s quilt was displayed in the Modern quilts section at the APQS show in Charlotte, NC in Aug 2014. Cheryl is a chemical engineer/patent agent and a quilter – what a talented lady!
And how wonderful that today is also Albert Einstein’s 136th birthday … So let’s eat birthday
cake pie in celebration!
