I WOULD have put this in the failt leet day thread, but it was CLOSED :(
Pi day celecbrations at my college included:
1. "How to find Pi when trapped on a desert island!"
2. "Who's birthday appears in Pi first?!" Prize: Pencil with Pi on it
3. The Pi song! (not in my class (un)fortunately)

GAH!
Too many coincidential dates are happening so fast.
My school didn't do anything about it. :(

This one happens every year though, and only in the US, so it's not as unique as leet day.

Come back on the 31st of April.
EDIT: Which doesn't exist. Now I feel a fool.
DAMN YOU, JULIUS CAESAR!

It's not like you actually need to know any more than that off by heart.

Yeah, but I have a veeerrrryyy boring maths teacher, a small, relative to other kids in my school, obsession with Pi, and a scientific calculator. What would you do in my position?

I used to know around 70, but I only know 50 or so now (my algebra II class was incredibly boring).

"Pi is exaclty equal to three!"
Sorry, I had to do it.

I prefer e anyway.
Aside from anything else, the first sixteen digits are really easy to remember.

Please, don't remind me any more of Decision maths. If I have to do a shortest path algorithm one more time, I'm actually going to scream. :p

I have a fried who knew 100
That was last year and knowing him he probably knows MORE by now :\

Even so, couldn't you just sleep or something?

I used to read my book under the table, didn't get caught much. I also used to build bridges between the desks, though she weren't as happy about that.

My little sister learnt it to 300 d.p for a competition.

Okay then.
Without looking it up, why is 1729 special?

Because I was forced to sit at the front of the class, so I couldn't even read something. And it was more interesting than listening to my teacher spending half the class trying to figure out his own pathetically easy warm-up problem. It was worth it, though. I got extra credit in my calc class for reciting some of it in front of the class. Some senior apparently memorized over 300 for pi day, though, so 50 is nothing.

leo tolstoy was born in 1828. that's how i remember it. tolstoy's year of birth, that is. i remember the e digits from using it all the time.
oh, and the simplest algorithm for computing pi is by starting with a regular hexagon inscribed into a unit circle, then recursively subdividing it into 6*2^n-gons. the perimeter of the later will start approaching the circumference of a unit circle, and therefore, 2*pi.
Without looking it up, why is 1729 special?
not 100% positive, but i think these are first 4 digits of sqrt(3), which also happen to be george washington's birth year. (edit: nope. that's 1732.)

Hey, you may know all of that crazy, but...
I know... PYTHAGOREAN THEOREM!

That shut you up. :p

but can you prove it?

I'll take a blind guess it has something to do with prime or square numbers.

All wrong so far.
C'mon, it's one of the most famous numbers in obscure number facts history!

Pigbuster
17 Mar 2007, 15:46
It's the smallest number expressible as the sum of two cubes in two different ways.
1729 = 1^3 + 12^3 = 9^3 + 10^3
I totally didn't copy that straight from Wikipedia.
