It would be nice if such articles more often gave a glimpse into the nature of research, rather than serving, as Bill puts it, entertainment. However, I disagree on the role of proofs in expository writing. Clearly, proofs are central in mathematics. But to say that mathematics is only about proofs is a bit like saying that dentistry is only about clinical research. Of course, the research is important, and most of us who have root canals are very glad that it is being done. However, I would like to believe that mathematics is ultimately about solving problems that *matter*, and the reason they matter often has nothing to do with their proofs. I am of course not advocating replacing proofs by conjecture. I am only speaking of expository writing, where I believe it is often more important to explain the results than their proofs. And sometimes, it can even be justified to give an "approximate" proof, i.e., a proof idea, or even an "approximate" definition, if it is stated clearly that there has been some simplification. The poor state of mathematical exposition is not confined to articles about mathematics. The following quote, from an ordinary new article in yesterday's Times, send my logic-circuits spinning: French lawmakers, for example, gave preliminary support this month to a measure that would require the company to open the iPod to play music purchased from any online music service; currently, songs purchased from iTunes can be played only on iPods. New York Times, 2006/03/29, "Apple vs. Apple in Dispute Over Trademark" This is of course not a logical contradiction; but I would be very surprised if it is what the writer really meant to say. Sadly, most readers probably won't know the difference one way or the other. -- Peter
