If you divide the circumference of the circle by the diameter, you will get approximately 3. A larger circle will have a larger circumference and a larger radius, but the ratio will always be the same.

If you could measure and divide perfectly, you would get 3. Otherwise said, if you cut several pieces of string equal in length to the diameter, you will need a little more than three of them to cover the circumference of the circle.

Pi is most commonly used in certain computations regarding circles. Pi not only relates circumference and diameter. Amazingly, it also connects the diameter or radius of a circle with the area of that circle by the formula: the area is equal to pi times the radius squared.

Additionally, pi shows up often unexpectedly in many mathematical situations. A History of Pi notes that by B.

Both the Babylonians and Egyptians had rough numerical approximations to the value of pi, and later mathematicians in ancient Greece, particularly Archimedes, improved on those approximations. By the start of the 20th century, about digits of pi were known. The third thing that bugged me was Beckmann's occasional lapses into opaque mathematical formulas.

To his credit, he does include a helpful tip in his introduction: "The reader who find the mathematics too difficult in some places is urged to do what the mathemeticians will do when he finds it too trivial: Skip it.

Among these little problems, however, arises the " Factor". This Factor manifests itself in a few amusing ways, not the least notably in the book's final chapter apparently added in its third edition about "The Computer Age".

Its like basking in the delight of a five year old's amazement when you pull a quarter out of their ear. It's just so adorable. The other amusing side effect is Beckmann's unmasked distate for those darned communists!

Amid the sometimes dry historical accounts and the calculus equations and geometric theorems, the author just can't help himself and throws in several rather opinionated rants against those pesky Soviets.

They made for some odd juxtapositions that brought a smile to my face every time they came up.

It's just a weird tangent to wander into in the middle of a text on the history of mathematics. But it didn't quite live up to the mysterious awe inspired by the Preston artical that led me to pick it up in the first place.Take one piece of string and place it on top of the circle, exactly once around.

The key is simply the approach. As a history of pi, it kind of doesn't really work for a couple of reasons.

Pi not only relates circumference and diameter.

In that single chapter, Preston did a fascinating job of pulling you into the bizarre world of pi, and made me understand why a mathemetician could get lost in all those infinite, endless numbers. Secondly, Beckmann does absolutely nothing to make pi seem like the awesomly inpenetratable number that it is.

Among these little problems, however, arises the " Factor".

But even there, its far too anecdotal to serve as any real history lesson.
