Don't you mean that there won't be another Pi Day like this in ONE HUNDRED (not one thousand) years? In 2115, the date will also be written as 3/14/15.

100 years.

I love that the Exploratorium gets the recognition.

Beef pie, followed by cherry pie, thanks. And you?

So John, What is it 1,000 or 100 years? If it's actually 100 years please correct the article. Thanks. Wouldn't want any pies tossed.

Readers- I was the author of the article. I asked several of my engineer, mathematician and scientist friends, "when is the next year this kind of Pi day will occur?" They were spilt down the middle: 50% said in 1000 years (due to the zero in the hundreds place), and 50% said in 100 years. The remaining 50% of mathematicians said "it depends". (a little Pi day humor there). Roughly the same proportions for the 9th digit, i.e. "exact seconds". Half ignored the 10th digit of Pi, half rounded up to make even. The remaining half quibbled about "leap seconds", rotational speed of the Earth and so forth. We all agreed - even the mathematicians- on two things: 1) we can't wait until the Pi year celebrations in year 3141 - the parties will be spectacular!, and 2) we all like pie.

150% ????

Those math guys. Always full of laughs.
