Enjoy this last day of September. Enjoy beautiful sunrises and sunsets. For those in the north, enjoy the changing of the colors. Have a terrific weekend and those traveling to the PTC conference - safe and effective travels....
An engineer, a physicist and a mathematician have to build a fence around a flock of sheep, using as little material as possible. The engineer forms the flock into a circular shape and constructs a fence around it. The physicist builds a fence with an infinite diameter and pulls it together until it fits around the flock. The mathematician thinks for a while, then builds a fence around himself and defines himself as being outside.
