Math Lab
Many people regard mathematics as the crown jewel of the sciences. Yet math has historically lacked one of the defining trappings of science: laboratory equipment. Physicists have their particle accelerators; biologists, their electron microscopes; and astronomers, their telescopes. Mathematics, by contrast, concerns not the physical landscape but an idealized, abstract world. For exploring...

Jazzing Up Euclid's Algorithm
Earlier this year, the journal Computing in Science & Engineering (CISE) published a list of the top 10 algorithms of the century (see http://computer.org/cise/articles/Top_Algorithms.htm).
"Computational algorithms are probably as old as civilization," Francis Sullivan of the Institute for Defense Analyses' Center for Computing Sciences in Bowie, Md. noted in an editorial in the...

Pi à la Mode
Memorizing the digits of pi–the ratio of a circle's circumference to its diameter–presents a hefty challenge to anyone undertaking that quixotic exercise. Starting with 3.14159265, the decimal digits of pi run on forever, and there is no discernible pattern to ease the task.
The apparent randomness of pi's digits has long intrigued mathematician David H. Bailey of...

The Physics of Baseball, 1994
Even in baseball, there's pure science and there's applied science. Mechanical engineer LeRoy W. Alaways has been pursuing a bit of both.
On the one hand, he...
