It’s Pi Day tomorrow! A very special Pi Day, because on March 14, 2015, at 53 seconds past 9:26 AM the date and time will spell out the first 9 decimal digits of the constant π. I’ll be celebrating by eating pie.
This GIF is a visual representation of C = 2r*π (the relationship between the circumference and the diameter).
*Thesesmartfolks have pretty much convinced me that Tau (τ=2π=6.2831…) is actually a better constant.And on Tau Day (June 28th), I get to eat TWO pies. But we have to wait until 2031 to get those extra decimal digits for τ.
Get ready to roll out some dough, because it’s Pi Day!
What’s that, you ask? Think back to geometry class. Pi represents the ratio of a circle’s circumference (the distance around the circle) to its diameter (the distance across it). In mathematics, it’s been represented by the Greek letter “π” since the 1700s.
For the math challenged, think of something that’s round. Might I suggest … pie? It’s the perfect example because, in addition to being round, it’s pronounced the same way as pi. And you can even use pies to calculate Pi, more or less.
Now, it’s been a long time since I sat in math class and learned about pi. Here’s what I remember: The value of pi is about 3.14159. (The value of pie, on the other hand, is, of course, deliciousness.) Pi is often shortened further to 3.14, but it actually goes on forever.
Some genius grasped the idea before I did and started Pi Day — which, of course, is celebrated with pie.
my confirmation bias knows no bounds lol: unrelated and probably unmathematical superstitious stuff but after the decimal, it takes you 27 numbers to get to the first 27 in Pi: 3.14159265358979323846264338327
Happy Pi day! Hope yall get some of your fave flavored pie in celebration
