Pi

[trustedsamurai7000]

Seeing as it was pi day yesterday I figured I'd start a topic about pi. Just somewhere to talk about this famous irrational number or brag about how many digits you've memorized or lament about not having memorized enough of them. So go ahead and have an in depth conversation about it or just show your love for it. Oh and happy belated pi day everyone!  

[Layra-chan]

The songstowearpantsto guy has a very nice mnemonic for the first fifty digits. It's on songstowearpantsto.com and is entitled "I am first fifty digits of pi"

While irrational and transcendental numbers are interesting, not being a mathemitician myself ( computer science: the lazy man's math xd ), I don't understand the significance of continually calculating further digits of Pi. Could anyone explain this to me? Is there any reason beyond simple bragging rights? I can't think of any kind of calculation that would need millions of significant digits.

I think THIS will answer all your questions!

I really don't think there is. I could be wrong but I'm pretty sure it's just for the heck of it. I think people just like pi because one, it's a cool number and two, it sounds like pie. smile

Here's a common(ish) question to mull over... Should Pi be redefined as the the ratio of the circumference of any circle to its radius? Would it make maths and physics pretty?

I think this is mostly a question mulled over by people who do order-of-magnitude analysis and want their negligence of factors of 2 to give an exact answer anyway xp

I particularly like e^pi. It's greater than pi^e, and the derivitive of e^x at x=pi is still e^pi. SO MORE PI FOR EVERYONE! Specifically apple pi.  

[Theoretical Physicist]

I wish for pie for everyone!

I mean pi. ninja

Some people think information could be gathered from the further calculation of pi. They expect some sort of patterns of codes to be in it, though I am not sure why they think that.

That said, there are some legitimate interests in calculating pi for computer science.  

[Chaotic Nonsense]

I remember reading somewhere that the first 27 digits of pi are sufficient to calculate the circumference of the universe (possibly just the milky way...) within 1 hydrogen atom of perfect.

On the subject of exponents of e: e^(pi*i) baffles me.  

[Theoretical Physicist]

E^...Pi? eek

I think I has something like that. It's called Super Pi.

Super-Pi^x = circumference of the universe.

How might I be of assistance?

In my high-school Calculus class a few years ago, we celebrated pi day by having pie (obviously). But we made all of our pie in square pans, so we had square pie. ><

We had a good day that day.

Hope that helps! Have a nice day!

I'd have done half-pies. Then they'd have been pie radians.

We need a pi shaped pie.
With apple and calculus inside it. 3nodding
