Happy Pi Day 351
Jonathan writes "Today, the 14th of March, is Pi Day 2008. Pi Day is internationally celebrated in honor of the mathematical constant "Pi," who's actual value will — now and forever — remain unknown. NeoSmart Technologies has a run-down on the history of Pi, Pi Day, and the significance of Pi and other such "magical numbers" to science and technology. 'Pi isn't just a number that you can use to calculate circle-related mathematics, it's a symbol of something by far greater. Pi is one of many "magic" numbers that are found everywhere — if you know where to look. These magic numbers can't be explained, they just are. And if you use them right, they make it a lot easier to do a lot of really complicated things... In a way, they're a testimony to technology and computers (or vice-versa, depending on how you look at it).'"

Pi Day? Sing it! (Score:3, Interesting)
Lots of songs have been written about Pi Day (Google "Pi Day Songs" to find 'em).
One of the more creative is this rap song (with video) [teachpi.org] to the tune of Eminem's LOSE YOURSELF.
Best enjoyed with a slice of pie. Right, Agent Cooper?
alternative representation in modular arithmetic (Score:5, Interesting)

The proper representation is modular-place arithmetic. Instead of assuming each number chunk is either decimal or hundreds, you use the actual size of the place. The Calendar places are:
12 months
31 days
24 hours
60 minutes
60 seconds
So 3.14159265 is
3 months, remainder
4 days, remainder
9 hours, remainder
20 minutes, remainder
42 seconds, remainder
In other words March 4 9:20:43

Good book about Pi (Score:3, Interesting)
I found it entertaining and easy to read while at the same being informative/interesting. I feel the book gives a very good presentation of the thought process behind how different civilizations reached their approximation of Pi and a good insight into how brilliant people of different times where able to calculate Pi. I bet a lot of "ordinary" people wouldn't have a clue about how to find a good number for Pi, without hitting their "Pi"-button on a calculator
A good read. Very nice addition to say, your toilet library (I've got one...)

Watch out for June 2 on this evenly-numbered year - that'll be Dick Tracy day!

The patron saint of imperfection frees us from our sin.
And if our transcendental lift shall find a final floor,
Then Man will know the death of God where wonder was before.

You can do non-integer bases, but it gets interesting. Non-rational bases get even more interesting. Maybe not practical for much, and you can't represent the "normal" integers usefully, but it's still a field and all of the abstract algebra still works.
