    Winning the World Series with math

    To run the bases faster, baseball players just need a bit of mathematics, according to research by an undergraduate math major and his professors. Their calculations show that the optimal path around the bases is one that perhaps no major-league ball player has ever run: It swings out a full 18.5 feet from the baseline.

    The precise path the researchers calculated probably won’t...

    Spoil-Proofing Elections

    When Ralph Nader recently announced he was entering the 2008 presidential race, many Democrats groaned. It was his fault, they say, that George Bush defeated Al Gore in 2000. But Nader retorted that the Democratic Party has only itself to blame for the loss in 2000.

    Mathematicians offer a different perspective. The problem, they say, doesn't lie with Nader or with the Democrats. It lies...

    Primal Progress: Pattern hunters spy order among prime numbers

    Mathematicians have taken a step forward in understanding patterns within the primes, numbers divisible only by 1 and themselves. According to the new work, the population of prime numbers contains an infinite collection of arithmetic progressions—number sequences in which each term differs from the preceding one by the same fixed amount.

    For example, in the sequence 3, 5, 7, each prime...

    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...

    Great Computations

    Computers at home or in the office often sit idle for minutes, hours, or days at a time. The Internet now allows researchers to take advantage of this enormous reservoir of unused computer power.

    More than 1.6 million people have downloaded software to sift through signals collected by the Arecibo radio telescope in Puerto Rico as part of a search for signs of intelligent...

    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...

    Pitching Science

    The pitcher's action up to the release of the ball is part of the art of pitching; the action of the ball after release . . . is addressed by physics.

    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 and his...
