Just remembered another story: There was a test trying to find out whether all odd numbers were Primary Numbers (numbers that only divide in 1 and themselves). The Engineer started and said: "I proved that 2, 3, 5 and 7 are primary, and concluded that the rest are thus primary as well." The Physicist tested and said: "2, 3, 5 and 7 are primary. 9 is an experiment inaccuracy. 11 and 13 are also primary - Assumption proved." Then the mathematician said: "2, 3, 5 and 7 are primary, 9 isn't - assumption incorrect!" Good thing we have Mathematicians ;P P.S. I won't even mention the Biologist... ;P Isaac Sasson, Small time programmer - complainer at large. Sonork ID 100.13704
