Two elderly women were out driving in a large car. Both could barely see over the dashboard. As they were cruising along they came to an intersection. The stoplight was red but they just went on through. The woman in the passenger seat thought to herself "I must be losing it, I could have sworn we just went through a red light."
After a few more minutes they came to another intersection and the light was red again and again they went right though. This time the woman in the passenger seat was almost sure that the light had been red but was really concerned that she was losing it. She was getting nervous and decided to pay very close attention to the road and the next intersection to see what was going on.
At the next intersection, sure enough, the light was definitely red and they went right through and she turned to the other woman and said, "Mildred! Did you know we just ran through three red lights in a row! You could have killed us!"
Mildred turned to her and said, "Oh, am I driving?"

Sir John Leslie

Died 3 Nov 1832 at age 66 (born 10 Apr 1766). Scottish physicist and mathematician who first created artificial ice. His practical scientific investigations led to his book Experimental Inquiry Into the Nature and Propagation of Heat (1804), dealing with the fundamental laws of heat radiation. Leslie gave the first correct description of capillary action (1802) and invented many instruments, most notably an accurate differential air thermometer, and also a hygrometer, a photometer, the pyroscope, atmometer and aethrioscope. In 1810, he devised a method of obtaining very low temperatures, by evaporating water in a receiver evacuated with an air-pump but containing a drying agent. His mathematical works include texts on geometry, trigonometry and The Philosophy of Arithmetic.
