What is pi?

Is there more to this definition?

What is pi?
Pi is the sixteenth letter of the Greek alphabet and represents the ratio of a circle's circumference to its diameter. It's mathematical value can be calculated to an infinite amount of digits with no patterns, however most people simply represent the number 3.1416 with pi.

If you're wondering why I'm asking, I am doing a project on Numbers Occuring in Nature and am doing two posters (one on pi, one on e) and then a report on Fibonacci Numbers. Whee, all last minute, sounds like fun 🙂

Take a look at the current research into the normality of pi, there is a short article in the current Scientific American about it. In short some researchers have found a way to calculate digits of pi or log 2 without having to know any of the preceding digits. Previously this was assumed to be impossible.

Thanks, I looked at the Scientific American site but I couldn't find the article you were talking about. I'll mention it on the poster though. Thanks 🙂

Anyone got any good pi links? Google brings up the dullest results.

Pi is the sixteenth letter of the Greek Alphabet ?p,? and represents the ration between a circle?s circumference and its diameter. The number pi is an irrational number and occurs in nature. Pi can be calculated to an infinite amount of digits but the value 3.14 is most often associated as the value of pi.

I added in the occuring in nature and irrational number stuff. I have to take up space.

bsobel -- I have a little section on calculating pi where you're definition is going to be used.

Pie comes in about 3,000 flavors, from key lime to apple to lemon merangue (sp?) to chocolate to peach cobbler to blueberry to, well, virtually everything imaginable. Choosing a favorite is always hard.

It's in the same issue as the multiverse article. It's there, I read it.

Heh, thanks 🙂

Lemon Merangue > * though

my pre-cal teacher went to Georgia Tech. the cheer they did at the basketball games was similar. "sine, cosine, tangent, pi, 3.14159, go yellow jackets!"

*sigh* good times...
 
PI is irrational due to its use in calculating a non existant. A circle cannot exist... All activity in nature abhors it and always seeks the tangent... because of this attitude a circle cannot be.. as indicated by the absence of the final digit to define a true circle... Tell your Calc Prof that Zero cubed can equal One... Then change majors to something more reasonable like Economics where everything relies on circular motion and reasoning..
 
There was a method discovered to calculate the nth digit of pi in hexadecimal notation without having to calculate any previous digit. Crazy stuff.
 
Ask a mathamatician what pi is, he will tell you it is the mathamatical ratio between a circle's circumfrence and its diameter.

Ask an engineer what pi is and he will tell you "about three."

Ask an economist what pi is and he will say "whatever you wish"
Ask an accountant what pi is and he will say "the definitive relationship between cash flow and the balance sheet" or "a chart depicting the fictional and fractional activity as presented by management"
