Pi day!!!

maxnick · Post by **maxnick** » Sat Mar 14, 2009 11:06 pm

Today is Pi day!

Pi's first 3 digits are 3.14

3 = March (the 3rd month) and .14 = 14th day so today is Pi day!!!

LOL! My family made a pie with the pi symbol in it as a celebration!

what does pi mean?

dlcs18 · Post by **dlcs18** » Sun Mar 15, 2009 12:35 am

From Wikipedia:

"Pi is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius."

...

......

Can someone please translate that into English?

Emerald141 · Post by **Emerald141** » Sun Mar 15, 2009 12:44 am

Here's the translation:

Pi= 3.1415926539... never ending, never repeating.

Finding the area of a circle- Pi times radius squared.
Finding the circumference of a circle- Pi times diameter.

Hope that clears it up.

You mean 2D circles.

But, but, it IS English!

Wikipedia is saying that the diameter of a circle times pi equals the circumference of the circle, and that the radius of a circle squared times pi equals the area of a circle.

BTW: Pi is approximately 1.4 trillion digits. So it does end.

Pi is "approximately" 3.14, and if you need precision, 3.1415926. But the exact number, the "pi" does not end.

That's right. pi is not a rational number...until proven.

Look it up, and you'll see.

From the same wikipedia article:

Because π is an irrational number, its decimal expansion never ends and does not repeat.

Please look up your math before posting nonsense.

Please don't treat me like that, Muzo. I've gone on Wikipedia a lot more than you know, I think.

Well no offense mqdar but Wikipedia isn't the most trustworthy site out there...

No, because I have an account on there

I've heard other people say that sort of thing too, did you know? Well anyway, there is a site that says a supercomputer calculated pi to 1.5 trillion digits, and stopped at nearly 1.4 trillioin. I'm not trying to destroy the amazing idea and wonder of pi (and they weren't either, in fact), but according to that, pi does end. How would it not?

I wouldn't make such a decision if I didn't have proof.

Since you don't have a link to the site I can't look at it, but I'm pretty sure you misread what they wrote. It's likely that their supercomputer stops computing because it runs out of memory or similar, or that they simply set aside a certain amount of time for doing it (after all, there are more important things for a supercomputer to compute these days) and time runs out. It's been proven since like the 17th or 18th century that Pi is irrational and therefore its decimal expansion is nonterminating and nonrepeating. The fact is, mathematically no one really cares about the 1.4-trillion-th digit of PI; computing PI is basically now in the territory of testing supercomputers and setting world records.

EDIT: OK, OK, I take it back. Is it this site?
http://watleyreview.com/2004/062904-3.html

DOUBLE EDIT: First of all, this is the only site that claims this impossibility.
And, second, while on that site... mqdar, have you EVER pressed the "disclaimer" button?

I think not.

The Watley Review is dedicated to the production of articles completely without journalistic merit or factual basis, as this would entail leaving our chairs or actually working. Names, places and events are generally fictitious, except for public figures about which we may have heard something down at the pub. All contents are intended as parody and should be construed as such. We have no agenda other than the depletion of Uncle Zeke's whaling trust fund and the dutiful appreciation of smooth, smooth liquor. The Review is updated every Tuesday or when the hangovers wear off, whichever comes first.

This is quoted directly from their disclaimer. The parts that I bolded show the "trustworthiness" of the site. It's good for a laugh, though.

Qloof234 · Post by **Qloof234** » Sat Mar 21, 2009 4:55 pm

BEST. DISCLAIMER. EVER.

mqdar · Post by **mqdar** » Sat Mar 21, 2009 8:36 pm

Yay, Muzo, you found the site.

No, I don't ever click the "Disclaimer" button, and I don't pay any attention to them anyway. I'm not sure I really knew what it meant, but I do now.
So, the site isn't really supposed to be trustworthy, is it? Oh no...
Wikipedia would hate it.

It is somewhat ironic that Wikipedia does have (as of Mar 22 2009 8:19am UTC) a page about the site (The Watley Review) explaining exactly the nature of the website.

Basically another Onion knock-off. Didn't I read somewhere oh wait, here that some Chinese reporter once mistaken something from The Onion as real news? mqdar must've been working there.

How many digits do you guys remember of Pi?

I know 35 after the decimal dot - 3.14159265358979323846264338327950288.
I've seen people on Facebook who remember 87 and more, though, so don't be so shocked.

billy bob · Post by **billy bob** » Fri Mar 19, 2010 12:47 pm

I can remember 0.

If you told me 3 numbers I would forget them in 10 minutes.

If you told me two numbers I would have to focus really hard on the numbers you told me and then I might remember them in 10 minutes, if I tried to do something while remembering I would forget.

There should be a square root of 2 day, and an E day. =D

They are all irrational numbers that are famous.
