(CBS SF) — March 14th has been known as Pi Day ever since math promoters realized the fun that could be had with the date, but in 2015, Pi Day really is significant as the mathematical moment of Pi–3.141592653–will only come around once in a lifetime, on March 14th, 2015 at 9:26 a.m. and 53 seconds. It will be a moment captured in mathematical perfection for fans of the mathematical constant representing the ratio of a circle’s circumference to its diameter.
For those like us in the U.S. who use the Western Calendar, we can watch our smartphones and clocks tick over to that time, and have the enjoyment of living during the instant of “Pi” carried out to 10 digits.READ MORE: 2 Killed in Separate Shootings Saturday in San Francisco Potrero Hill Neighborhood
A moment like this won’t be back for another hundred years, March 14th, 2115.
You can celebrate by waiting out front of the the Exploratorium in San Francisco (it opens at 10am, just after the perfect Pi moment). It’s FREE on Saturday for Pi Day.
You can enjoy musical inspiration too.
T-shirt sales on CafePress are already brisk (examples here), with plenty of designs to choose from. You’ll have to draw your own at this point though, as shipping probably won’t make it here by Saturday morning.
For that, we at CBSSF want to help you honor Pi Day with first a link to everything Pi (Click here for PiDay.org), and second, Pi written out to a ridiculous number of digits.
