Math in the Media 0501

What color is my hat? This is the crux of ``the hat problem,'' as presented to readers of the Science section of the New York Times on April 10, 2001. The article, dispatched from Berkeley by Sara Robinson, describes the puzzle as follows:
There is a strategy, and the surprising thing is how well it works. In fact, when the number n of players is 1, 3, 7, 15, etc. (one less than a power of 2) the strategy promises a win n/(n+1) of the time. That strategy is given in terms of Hamming codes, a special class of errorcorrecting binary codes that sit at the intersection of electrical engineering and abstract algebra. Robinson interviewed Elwyn Berlekamp, the Berkeley math professor who worked out this strategy. She quotes him giving the following life lessons to be deduced from the problem: ``The first is that it's O.K. to be wrong as long as you contrive not to be wrong alone. The other, more important lesson is a need for teamwork that goes against the grain of most mathematicians. If the evidence suggests someone on your team knows more than you, you should keep your mouth shut. Most of us assume that each player's strategy is oriented toward him getting it right, and it's not. It's the whole team." Schools' `New Math' = Trouble for City Kids. was the headline inside the April 17, 2001 New York Post. ``BIG FAT MINUS'' was the grabber on the cover. The story, by the Post's Education Reporter Carl Campanile, is about the NYC Board of Education's implementation of the NCTM guidelines, which are characterized thus: ``The socalled `constructivist' programs minimize use of algorithms, long division and other basic math equations is favor of students working in groups and `discovering' their own answers from reading passages.'' Campanile quotes mathematicians Fred Greenleaf (NYU): ``We're condemning an entire generation of students with fuzzy math'' and James Milgram (Stanford): ``Why should they use these programs in New York after what happened in California?'' Supporters of the program don't get much room. There is only Spud Bradley, an NSF program director, telling us that ``... lowincome kids ... have performed better than with traditional materials,'' and this important point is not expanded on. A suplementary article by Campanile (``Bad news for children, good news for tutors'') tells how professional tutoring services are teaching the basics (``familiar equations and algorithms'') to students frustrated with the `` `fuzzy' math.'' An opinion column by Rod Dreher rounds out the spread: ``Constructivist math is in part based on a bizarre theory that traditional arithmetic is biased towards white males.''
Alan Alda, math wannabe. Science reporter K. C. Cole has a long and erudite piece about Alan Alda and the popularization of science (``Alda Takes On an Ancient Role in Popularizing Science''), in the April 26, 2001, Los Angeles Times. The comedian has been involved of late with bringing science to a large TV audience through his programs for Scientific American Frontiers. His ambition is ``promoting understanding.'' ``How do you figure out what to believe," he asked Cole, and went on to explain that discerning the truth doesn't require that we all become scientists, but it does require that we base our beliefs about the world on investigation rather than faith. And learning how not to be fooled. This is the context in which he told Cole that he wished he'd learned more math, and that he has plans in that direction. "Maybe I could learn to do an equation!" Alan Alda is currently embodying the protagonist in QED, a play about Richard Feynman at the Mark Taper Forum in L. A. Pulitzer for Proof. Felicity Barringer's April 17, 2001 New York Times story about the 2001 Pulitzer Prizes had a sidebar about the individual awards. The prize for drama went to ``Proof," David Auburn's ``surprise Broadway hit." ```Proof' focuses on the madness and death of a famous mathematician, his ardent student and his two daughters, one of whom may have inherited her father's genius, his illness, or both. Structured as a mystery about the authorship of a mathematical proof, it is really about more ethereal mysteries  the chemistry of love, the nature of genius." The Times obtained the following modest quote from Mr. Auburn: ``I never knew that this small play with mathematicians as characters and set on a back porch could attract so much atention." Benjamin Peirce in The New Yorker. The April 23 & 30, 2001 issue of that magazine contains, embedded in Louis Menand's ``Dept. of Avarice" piece ``She Had to Have It," a colorful portrait of Benjamin Peirce, the Harvard professor who was ``the first internationally recognized mathematician the United States produced." The context is Pierce's 1867 appearance as a witness for the defense in the suit brought by Hetty Green (18351916) against her aunt's estate. Hetty had produced a second will, bearing her aunt's signature in two places, and leaving the aunt's considerable fortune almost entirely to Hetty. According to the estate, this document was a forgery; their evidence was that the two new signatures were absolutely indentical to the aunt's signature on her original, witnessed, will. Pierce and his son, the equally famous Charles Sanders Peirce, calculated that the likelihood of such a pair of sequences of coincidences was one in 5^{30}. In the end, the case was decided on a legal technicality (Hetty lost). But here is part of Menand's portrait of Benjamin Peirce. `` ...he cultivated a certain wizardliness of manner. His hair was irongray; he wore it long with, in later years, a thick beard. And his obscurity was legendary. It was said at Harvard that you never realized how truly incapable you were of understanding a scientific matter until Professor Pierce had elucidated it for you." ``A Beautiful Mind" the movie. The cast is assembled in Princeton, and filming has begun on the screen version of Sylvia Nasar's biography of John Nash. (The movie will now bear the same title as the book.) Jennifer Yachnin reports the goingson in ``From Brawn to Brains" (Chronicle of Higher Education, April 6, 2001). As the title suggests, the piece is focussed on Russel Crowe, and the transition from his Oscarwinning dusty, sweaty gladiator to a mathematician blessed with unique intellectual power but crippled by mental disease. Apparently some Princeton undergraduates think Crowe too crude for the job. As Yachnin reports, ``The actor didn't help his case any when he was caught on camera giving the finger to a junior who was trying to take his picture." But in fact Crowe's attitude seems completely appropriate to the contentious and prankish young genius portrayed by Nasar in the first half of her book. Tony Phillips
