43. Pi Experiments morning. The next evening it occured to me that this simple visualexperience was a way to calculate the value of pi. Basically http://www.hypercomplex.org/pi.htm

Pi experiments Home Members Fractals Quaternions ... Links Your browser doesn't support Java, please upgrade your browser or enable Java In July 2000 I had a strange geometrical dream in which I could see a circle circumscribing a regular polygon. The number of sides of the polygon was increasing so much that after a while it actually became the circle itself. At that point I woke up quite intreagued and drew what I had just seen on a piece of paper so I would remember it when I wake up in the morning. The next evening it occured to me that this simple visual experience was a way to calculate the value of Pi. Basically the concept was that if there is a link between the perimeter of a circle an Pi then there also was a link between the perimeter of a regular polygon with an infinite number of sides and Pi. The same concept can also be applied using the area of a circle and the area of a regular polygon instead of using their perimeter. I started with the perimeter method. If you draw a circle of radius r circumscribing a regular polygon of n sides the perimeter of the polygon is 2n r sin(Pi/n). If n=infinity then you get the most accurate value of Pi.

A rather good approximation to pi is given by the fraction We could also give here several `analytic' representations for this remarkable number. One of them is the so-called Gregory-Leibniz series: pi= 4 (1 - 1/3 + 1/5 + 1/7 - 1/9 + ...)

This is a typical result of generating n=100 random points. Here, 76 of them fell in the circle, so the estimated value is pi = 4 x 76/100 = 3.04, which is not too bad for using only 100 points. In fact, another famous result in probability, the Law of Large Numbers , says that if we used enough points, we could approximate pi as close as we wished with this method.

HEADLINES RANDOM ARCHIVE MORE STUFF ... WORLD TRIP Pick of the Best Read it! Quintessential Quote He early on let her know who is the boss. He looked her right in the eye and clearly said, You're the boss. Mathematician finds true value of Pi to be 3.15 Written by: Hungry Caterpillar Published on: 20 Apr 2000 For century’s scientists have thought that the number know as Pi was supposed to be an irrational number, infinite in length. But today Dr Richard Kimber announced that the value of the number is not 3.141592653589... and so on. It is in fact only 3.15. It seems that previously every mathematician that had tried to calculate Pi had in fact 'Forgotten to carry the two' and so got what is in actual fact a very simple sum completely wrong. The result of this finding is expected to have far reaching consequences. Its implications are going to be devastating as it is now becoming clear that for this entire time people have been calculating the area and radius of circles incorrectly. Also it will have implications in the errr well what ever else Pi is actually used for. We spoke to Dr Kimber who made this incredible discovery.

Date: Thu, 14 Aug 2003 16:52:08 -0700 - New Message on cochindotnet - From: Rakesh Rajan Message 1 in Discussion Hi all, Requesting all adventurous ppl to beta test my small utility: 'The value of Pi'. As the name suggests, it is a utility to find the value of Pi as well as fractions that evaluate to Pi. What u will need: .NET fx and loads of processing power(if u need to calculate more digits). Just unzip the attached file and execute. And of course, all the reports (bugs etc.) will be acknowledged :-) I started developing this utility to study mutilthreading (from the article Safe, Simple Multithreading in Windows Forms, Part 1-3 @ http://msdn.microsoft.com/vstudio/using/understand/xml/default.aspx?pull=/library/en-us/dnforms/html/winforms06112002.asp ) and modified and added some features of my own. I am happy to say that the app is now very generic and new algorithms can be easily added - I am targetting an algorithm plugin feature as run time .NET DLLs. Do send me comments, bugs etc. I want more inputs to make it better.

54. #Y26. PI In The Bible The real value PI = 3.1415926 But given that the value 3 is withinless than 5% error compared to the real value of pi = 3.14159 http://www.yfiles.com/pi.html

PI in the Bible By Jochen Katz 1 Kings 7:23 He [Solomon] made the Sea of cast metal, circular in shape, measuring ten cubits from rim to rim [diameter = 10] and five cubits high. It took a line of thirty cubits to measure around it. [circumference = 30] Since circumference = PI x diameter as any elementary geometry book will tell you, but the Bible "seemingly" tells us that PI = 3. Since "this is obviously false, therefore the Bible cannot be from God..." is how some people like to reason. But obviously the wisdom of God is greater than the wisdom of man: In this case the word for circumference = "line" ( in Hebrew) But in this verse "line" is written with an extra letter ( Since Hebrew has no digits, all letters are also numbers, we can take the ratio of (the gematriacal value of) the unusual word form ( ) to the regular word form ( ). Given that the gematrial letter values are = 6, and = 5 we find that: Ratio False number for PI Ratio TOTAL 3 multiplied by The real value: PI = 3.1415926... The difference between 3 x 111/106 and PI is 0.0000832 which is only an error of 0.00026%.

55. Mnemonics For The Number Pi The Hebrew peoples used a rough empirical value of pi in the Bible. The IndianaPi Bill of 1897 would have legally established the value of pi. http://ccins.camosun.bc.ca/~jbritton/jbpimem.htm

MNEMONICS FOR THE NUMBER PI There once was a fellow from Greece, Who forgot pi's last decimal piece. So he used electronics To collect pi mnemonics ... Now he's hooked, and there is no release. Michael P. Masterson-Gibbons School-children can always be found competing to see who knows the most digits of pi. My own interest and patience usually ran out at 3.14159. Pi is the ratio between a circle's circumference and its diameter. When expressed decimally it extends to infinity as a series of apparently random digits. Pi = 3.1415926535897932384626433832795028841971... Finding out pi's digits has been a major mathematical challenge ever since the invention of the wheel first stirred a real interest in circles. The earliest recorded values of pi were Phoenician (3 1/8) and Egyptian (3 13/81). Both values are accurate within a half a percent. Where did these values came from? From measurements? Well, try measuring pi with a piece of string. You won't come this close. The Hebrew peoples used a rough empirical value of pi in the Bible. It was three, and it's found in a text that shows up in both the 1st Book of Kings and the 2nd Book of Chronicles: And he made a molten sea, ten cubits from the

56. Efg's Buffon's Needles Lab Report Purpose The purpose of this project is to explore a Monte Carlo method of estimatingthe value of pi (p), which was first discovered by Count Buffon in 1733. http://www.efg2.com/Lab/Mathematics/Buffon.htm

Mathematics Buffon's Needles Lab Report 1,000 Needles Tossed Onto Parallel Lines Yield Approximation of p (Using Method 4 see text) Purpose The purpose of this project is to explore a Monte Carlo method of estimating the value of pi ( p ), which was first discovered by Count Buffon in 1733. Mathematics Background Take a number of toothpicks and randomly throw them on a tablecloth, a hardwood floor, a brick sidewalk, or on anything that has a number of equally spaced parallel lines. The parallel lines must be at least as far apart as the length of a toothpick. Count the number of tosses and the number of toothpicks that cross the parallel lines. The following formula gives you an estimate for p If you can find some parallel lines that are exactly as far apart as the length of a toothpick, the formula simplifies to: Figure 1. Tossing Toothpicks to Estimate the Value of Pi Figure 1 shows 7 tosses and 4 crossings, the formula tells us: p So our estimate is in the right neighborhood — it’s close to 3.141592653589793... Can we just keep throwing more toothpicks and get a more precise answer? Not really. You can use more precision on your calculator, but you’ll only ever be accurate to a few decimal digits with this method. Nevertheless, this "Monte Carlo" method of estimating a value is still useful for certain kinds of scientific calculations. Molecular chemists can use this method on a computer instead of beakers to explore how molecules react. Nuclear engineers studying how a nuclear reactor works can use Monte Carlo calculations to answer questions that have no other answers.

What book does this come from? Homer's Odyssey Ulysses by James Joyce The Bible A Brief History of Time by Stephen Hawking Douglas Adams' Hitch Hiker's Guide to the Galaxy 2.
