The World According to Mathematicians Engineers think that equations approximate the real world. Scientists think that the real world approximates equations. Mathematicians are unable to make the connection... ============================================================================= A Mathematician, a Biologist and a Physicist are sitting in a street cafe watching people going in and coming out of the house on the other side of the street. First they see two people going into the house. Time passes. After a while they notice three persons coming out of the house. The Physicist: "The measurement wasn't accurate." The Biologist: "They have reproduced!" The Mathematician: "Now if exactly 1 person enters the house, it will be empty again."
