Pi DAY SATURDAY!

Today is Pi Day!

The day on which the date is 3/14/15 (at least for those in the US and elsewhere that use this weird way of writing write dates!) matches with the first five digits of pi – 3.1415 – the ratio of every circle's circumference to its diameter.

BUT....
 
There's more... I am posting this at 9:00 am and in precisely 25 minutes and 53 seconds it will be 9:26:53 am and that will be a Pi Second when the date and time match up with the first 10 digits of pi: 3.141592653.

BUT...
 
Not only that... As University of Toronto statistician Jeffrey S Rosenthal has pointed out, at an infinitesimally brief moment just after 9:26:53.58979 am but slightly before 9:26:53.5898 am, we'll have Pi Instant!!
