Calculating Pi  LHH  09212013 I was thinking of calculating Pi for fun and found this: http://www.wikihow.com/CalculatePibyThrowingFrozenHotDogs
May be old news here!
Re: Calculating Pi  Dieter  09212013 Quote:I do not know if this has been discussed here earlier, but this experimental way of evaluating Pi actually is a well known method. However, the original implementation does not use hot dogs and floor tiles, but a box of pins and a sheet of squared paper. ;) BTW, I own a more than 30 years old book with sample programs for teaching computer science. One of the shown Pialgorithms actually is this experimental tossahotdog method.

Re: Calculating Pi  Gerson W. Barbosa  09212013 That's the wurst way to calculate Pi, IMO :) Gerson.
Re: Calculating Pi  Paul Dale  09212013 Buffon's needle I believe. I'm sure a worse way to calculate PI can be invented :)
Re: Calculating Pi  Gerson W. Barbosa  09212013 Quote: Yes.
Quote: Yes, like the one above that uses wursts instead of needles :)
Gerson.
Re: Calculating Pi  Paul Dale  09212013 I was trying to come up with a formula for PI based on the divergence of the sum of the reciprocals of the primes, a very very slowly diverging series. No success at this point :(
Re: Calculating Pi  Kimberly Thompson  09222013 LHH some helpful references;
Link to Buffon's Needle 1.0 BEST!

Re: Calculating Pi  Les Koller  09222013 "The wurst way"...OMG you guys are impossible! That's why I love you all. And yes, Buffon's needle...dropping needles on a flag
Re: Calculating Pi  LHH  09252013 Thanks for these links! Looks like I'll be busy for a while!
And forgive the delay, had to wait until I was on the computer that logs me in automatically. Can't seem to remember how to do that when I'm away from my main machine (its 24" CRT monitor frame is covered in sticky notes with all my logins!). Getting old!
Re: Calculating Pi  Gerson W. Barbosa  09272013 I have presented a few empirical formulas to speed up Archimede's Method here and here. In the second link there's an hp 50g program to compute pi to 1,000 places in "only" three hours using such method . Other very interesting pirelated links in there as well.
