So cool! Now we have to wait for 3/14/15926, a mere 13910 years from today.

You two are so far futured....

Why not 3-14-159? (i.e. 2159)

I noticed today at https://en.wikipedia.org/wiki/Chrono...tion_of_%CF%80 that this Peter Trueb person calculated Pi to 22,459,157,718,361 digits with software on November 11, 2016. I didn’t want to wait until Pi Day to tell you guys this because I might be busy on Pi Day or forget.

It is π^e * 10¹² digits:

The number is over 20 terabytes of information. Most people couldn't even store it on their available hardware. It is unbelievably huge.

And, yet, after about 10 digits or so, the precision is about as much as most people will ever need. I think at one point someone calculated the number of digits needed to calculate the circumference of the known universe to the width of a hydrogen atom, if we were capable of that type of precision, and it was only a few tens of digits, I don't remember the exact number.

Diameter of universe is about 100 billion ly = 11 digits
1 ly = 10^16 m = 16 digits
diameter of electron = 10^-18 m = 18 digits

Total precision needed = 11+16+18 = 45 digits (give or take)
