In brief a man with the improbable name of Arnold Arnold claimed to have solved Fermat's last theorem. Naturally all the vicious nasty establishment mathematicians wouldn't listen to him. He also claimed to be able to factor any number in reasonable time! His claims were taken seriously by the science editors of the Manchester Guardian and they published an article praising Arnold, attacking establishment mathematicians, making dire predictions that Britain's military codes were now insecure and presenting a summary of some of Arnold's results, including a large number Arnold claimed was prime. The media around the world reprinted the story, usually getting it wrong or embellishing it (no Cambrige mathematicians supported the proof!) and nobody bothered to check with a mathematician! Arnold's "proof" is nonsense! It is almost incomprehensible. Either Arnold does not understand the statement of Fermat's last theorem and has proven something trivial (the sympathetic view) or he is completely up a tree. Also rather embarrasing for Mr. Arnold is the number he claimed was prime was immediately factored (by rather elemetary methods). Mr Arnold has not demonstated the ability to factor large numbers. The British mathematical community replied to the Guardian article with a large number of letters, varying from the enraged to the sardonic. The science editors of Guardian withdrew their claims (though with rather poor grace). Arnold still claims to have solved Fermat's last theorem (naturally to understand his proof you have to read his complete paper). He does admit that there are a few bugs in his algorithm for checking large primes. New Scientist (a non-technical, British, science magazine) published a "rebuttal" of Arnold's claims. Unfortunately the math in their article was almost as bad as Arnold's. (Their presentation was clearer though so the mistakes were easier to see!) The moral. Don't believe everything you read in the popular press about mathematics. Even moderately prestigous publications like the Guardian and New Scientist can make idiotic mistakes. William Hughes
