Short Summaries of Articles about Mathematics in the Popular Press"On a Roll," by Dana Mackenzie. New Scientist, 6 November 1999, pages4447. Randomness is an important but elusive concept. Because random numbers exhibitno special patterns (otherwise they would not be random), mathematicians havefound it difficult to say much about them.
