Boss Issues

A boss was complaining in a staff meeting the other day that he wasn't getting any respect. Later that morning he went to a local sign shop and bought a small sign that read, "I'm the Boss". He then taped it to his office door.
Later that day when he returned from lunch, he found that someone had taped a note to the sign that said. "Your wife called, she wants her sign back!"

Max Mason

Born 26 Oct 1877; died 23 Mar 1961 at age 83.American mathematical physicist, educator, and science administrator. During World War I he invented several devices for submarine detection - several generations of the Navy's "M," or multiple-tube, passive submarine sensors. This apparatus focused sound to ascertain its source. To determine the direction from which the sound came, the operator needed only to seek the maximum output on his earphones by turning a dial. The final device had a range of 3 miles. Mason's special interest and contributions lay in mathematics (differential equations, calculus of variations), physics (electromagnetic theory), invention (acoustical compensators, submarine-detection devices), and the administration of universities and foundations.
