4/27    Musical renderings of mathematical constants:
        http://www.tomdukich.com/math%20songs.html
        \_ As mathematically derived music goes, pretty uninteresting.
        \_ Old, but cooler: http://www.theuser.org/dotmatrix/en/intro.html
           \_ Also old, and cooler: http://www.coverpop.com/whitney/index.php
              \_ that is super-cool.
        \_ It says it assigns musical notes to digits 0-9 to play the
           constants.  What digits do they use to represent sqrt(-1)?

4/19    6-yr-old boy with 15 fingers to have surgery to remove the "extra"
        fingers:
        http://www.csua.org/u/qll
        Are we killing off further evolution of the human species by acts like
        this where we surgically "correct" any variations that we think are
        bad?  This kid could have been a great piano or guitar player with all

        While I'm no fan of Condi's hawkish diplomacy, I've always admired
        people with multiple professional-level talents.

        (enjoy?)
        \_ Tell me what it is about and I might consider it.
           \_ It's just instrumental music man,
              The stuff you listen to while coding.

10/11   Are there any CSUA'ers in NYC, or who know things to do in NYC? steven
        and I are doing the tourist thing.
        \_ I thought the Empire State Building was much better than I
           expected it to be. The museums are all stellar, especially the
           Met, MoMA, and Natural History Museum.  Lots of good
           plays/shows/concerts. Top notch restaurants. Worth seeing the Statue

This section has audio and video pieces based on five famous mathematical constants. The constants were "sonified" by assigning notes from various musical instruments to the digits 0 through 9 What are the five famous constants? Two of the five are 1 and 0 These need little explanation. Most of us are familiar with the third: pi or the circumference of a circle divided by its diameter. The three dots mean that the decimal part goes on forever. The last is i, the square root of minus 1, or what is called an imaginary number. Leonhard Euler ( pronounced "oiler") related all five of these constants in what many consider to be the most beautiful equation in all of mathematics. This mysterious relationship is sometimes called the Magic 5 Equation: e to the power pi+1=0 All five of the constants are sonified in two separate audio pieces: Magic 5: Euler All At Once, and my personal favorite, Euler's Samba. Straight, as a Piano Solo, and in a more complicated way with Piano, Bass and Flute. It's represented visually as an animated pattern matrix in Pi's Digit Matrix. Finally, the Reverend Pi 357 video is my salute to all the number mystics out there. Like the weather sonifications, these result are surprisingly musical even though the original intent was not to write music but to listen for patterns. By selecting the various links below you can hear some of the "math songs". Look in the upper left corner of the Apple page, check your operating system, and uncheck the boxes to avoid the junk mail. If you just don't want to get QuickTime for free, some of the audio and video pieces can still be viewed using Windows Media Player, albeit at a lower video quality. Look for a link to Media Player by the description of a particular piece after clicking on it below. A good one to start with to familiarize yourself with how these sonifications were done. The same digit to pitch mapping was used in most of the following songs. The zero is usually not played as a note but shows up as a rest of the same duration as the notes in the particular piece.

in three minutes, the largest dot will travel around the circle once, the next largest dot will travel around the circle twice, the next largest dot three times, and so on.
