P vs NP Reviewed by Times

I mentioned this article some time ago, it was orginally in the Communications of the ACM, about one of the most difficult yet practical mathematical problems of the age. Now the NYT Science section has chimed in with their own short review, which emphasizes its value and also points out its difficulty. Like the CACM article, gives a reasonable introduction to the problem, but does not provide enough detail to show why it is hard.
