pie is simply 3
2002-12-06 09:06:55 PM  
wow do you know what this mean for mankind? I dont either
2002-12-06 09:07:31 PM  
boooring.... goes back to all the boobies in total fark.
2002-12-06 09:07:48 PM  
Mmmmm.... Pie......

I can sleep securely tonight!
2002-12-06 09:08:20 PM  
its not that hard of an algorithm, i played around with writing a program to do it a few years back, decided it wasn't worth the effort because i was damn sure i wouldn't let it run long enough to get that far
2002-12-06 09:08:38 PM  
The l33t computar did it, not the professor. Useless either way.
2002-12-06 09:09:10 PM  
NOW they tell us. This would have really helped me when I took the GRE the other day.
2002-12-06 09:12:07 PM  
Here's my question: How do they know that this is accurate? Perhaps some mathematical genius will help me with this because personally I think mathematics is a bunch of bullshiat. Anywho...
2002-12-06 09:12:20 PM  
I applaud this work, because I want to know what the hell the last damn digit of pi is. My money is on 7. I am pretty sure that that is the last digit.
2002-12-06 09:13:05 PM  
ASSHAT:Funny an engineer, the given tolerance for any project is usually 10%...for pi, you CAN substitute 3 for pi and be within tolerance. Do the math...scary.
2002-12-06 09:14:29 PM  
Does this Pi calculation help anyone? Is it used for anything?

Cancer researchers everywhere surrenders...
2002-12-06 09:15:21 PM  
TennesseeBuck - Mathmatics is what makes a computer work. Magical bullshiat it is .. :)

Mmmm... Floor Pi
2002-12-06 09:19:37 PM  
Ironically I am a Computer Science major but I believe mathematics is a human invention not a discovery.
2002-12-06 09:21:51 PM  
See the wonders of Applied Math everyone? Waste your time calculating π...

Well actually it's ego-stroking in the math world to come up with the most complete calculation of π. And the calculation is correct since we do indeed know how to get the other digits in π in the first place. This is assuming the computer that the mathematician used can hold such a number in its storage, which it does look like it can.

2002-12-06 09:23:07 PM  
TennesseeBuck - Perhaps, but that's just debating semantics IMHO... Math is a tool used to predict the actions of nature, so it must have something going for it....
2002-12-06 09:23:40 PM  
*sigh* coming from a family of 3 engineers i did not know that, all my brothers are engineers, im choosing to be a vet
2002-12-06 09:23:43 PM  
"And the calculation is correct since we do indeed know how to get the other digits in i€ in the first place."

Sounds like circular logic to me. Prehaps you should get together with Bevets and have a pow-wow. ;) (j/king)
2002-12-06 09:24:15 PM  
I think its best in eight pieces myself.

2002-12-06 09:24:33 PM  
does anyone remember when i posted pi to like the 5,000th digit????
ahhhh, the good old days....
2002-12-06 09:26:12 PM  
Great......shoot the professor, he obviously has nothing better to do than seek attention
2002-12-06 09:27:18 PM  
"Perhaps, but that's just debating semantics IMHO... Math is a tool used to predict the actions of nature, so it must have something going for it...."

Yeah true, but I just don't buy the whole 1/3=0.3333..infinity thing. Something's not right there. Then again, I'm one of these nuts who also thinks you can compress a file down to a few digits.
2002-12-06 09:28:58 PM  
*hits TennesseeBuck over the head with a baseball bat* :-P

Bmr68: Pies aren't round! Pies are square!!!!!

2002-12-06 09:29:31 PM  
TennesseeBuck - Hmm, well, that's an abstract mathmatical concept, not nature there. Decimal is a convenient way to represent numbers, but they're not very pretty. Stick with 1/3rd if you want to keep things exact. Stick with 0.33333333 to infinity if you want convenient. I'm a strong proponant of fractions whenever possible. Of course, this isn't possible with Pi, but whatcha gunna do?
2002-12-06 09:30:46 PM  
Actually I know π to be about 3.141592653 from memory -- I'm special ;-o
2002-12-06 09:31:36 PM  
Bmr68- I prefer six pieces, because I can never eat eight.

I can't imagine working five years on a project that has no real value. Is the self-satisfaction you get from calculating pi to that extent worth wasting five years? Not that my life is uber-important.
2002-12-06 09:34:35 PM  
"I'm a strong proponant of fractions whenever possible. Of course, this isn't possible with Pi, but whatcha gunna do?"

Cool. We can agree on that. Like I said earlier, I think its an invention. But dont get me started on that whole e=2.718..irrational infinity thing either. :)
2002-12-06 09:35:31 PM  
Awwwww.. but e is such a fun number, and useful too! :)
2002-12-06 09:36:17 PM  
e is a commie conspiracy! ;)
2002-12-06 09:40:41 PM  
I just checked his math, and he got the 39,452,518,654th digit wrong. I'm about to send him an email informing him of his error.

2002-12-06 09:40:52 PM  
how come you never hear about anyone calculating e to an arse-load of digits?
2002-12-06 09:40:59 PM  
Still no cure for my herpes either...
2002-12-06 09:41:34 PM  
Nightjars: e may be more practical, but π is still everyone's favourate irrational number. Personally I'm a fan of e and not π. You wouldn't believe how simple some very complex math gets with e. ;-)

"eπi - 1 = 0"

I prefer hairpie...

Hairpiece on my hair....

Not surprised how many people think this is pointless. You see this helps research in mathematical calculations.

If you want your cars to drive, or your buildings to work in your your computers to work mathematical calculations have to be quick and very precise.

For supercomputers, this level of precision is highly neccessary. Not when dealing with decimal places, but when dealing with 200 to 300 dimensions of numbers, such as what Air Traffic Controlling computers deal with. One number off and your plane will collide with another.

As far as Pi is concerned, well we dont know yet if it is truly an irrational number. We may find an infinite string of zero's eventually, and then it would be defined as rational.

Interesting thought that is, although it probably will not happen.

I love how e can simplify some higher order differential equations, and how without e you cannot get a solution to them :)

i is an even more interesting number, but is imaginary. However it opens up a whole new world of solutions to problems.
2002-12-06 09:53:08 PM  
I know pi to lots of decimal places off the top of my head.


True, I could be looking off of something, but I swear I'm not. Come on over sometime and I'll rattle 'em off with my eyes closed.

I wonder if pumpkin pi is significantly different from peanut butter pi?
2002-12-06 09:59:24 PM  
Well considering a pumpkin is similar to a circle whereas a peanut is simliar to two ovals I am sure there is some great difference. Personally I am more worried about the possible equation for American Pi.
2002-12-06 10:01:29 PM  
Valkhorn: Yes the precison of the calculation with a well-known irrational number is important, but it could of been done with any irrational number. π just happens to be a very ego-stroking number for mathematicians. The oldest of calculations though involve arctangent, which would make pi an irrational number that involves an infinate series, so who knows...
2002-12-06 10:06:02 PM  
Anybody read "Contact" by Carl Sagan...where at the end of the book, at the advice of the aliens, a team of scientists calculated Pi for years, up the the bazillionth digit, and found that the numbers turned into a string of 1's and 0's which, when decrypted, formed a 600 x 800 picture of a perfect circle, and that it was put there in the middle of Pi at the beginning of the universe as a secret message from God?

That would have been much cooler.
2002-12-06 10:06:43 PM  
1.24 trillion digits. Really.

One of my algebra teachers said that you can calculate the size of the universe to within a few atoms using pi to only 25 decimal places. (3.1415926535897932384626433)
2002-12-06 10:09:59 PM  
YourNameHere: Actually it's 50 digits of π.
2002-12-06 10:10:47 PM  
crap YourNameHere, I was about to post the same thing, execpt I heard that it was around 15 decimal places...

oh well...
2002-12-06 10:11:22 PM  
"Pi is exactly 3!!!!"

sorry it had to come to that
