An older man walks into a bar...

An older man walks into a bar wearing a stovepipe hat, a waistcoat and a phony beard. He sits down at a bar and orders a drink. As the bartender sets it down, he asks, "Going to a party?"
"Yeah, a costume party," the man answers, "I'm supposed to come dressed as my love life."
"But you look like Abe Lincoln," protests the bartender.
"That's right. My last four scores were seven years ago."

Ernst Heinrich Weber

Died 26 Jan 1878 at age 82 (born 24 Jun 1795).German anatomist and physiologist whose fundamental studies of the sense of touch introduced a concept, important to psychology and sensory physiology, that of the "just-noticeable difference", the smallest difference perceivable between two similar stimuli. With his brother Eduard Friedrich Weber (1806-71) he discovered the inhibitory power of the vagus nerve (1845). With another brother, W. E. Weber, he made studies of acoustics and wave motion. He formuled Weber's law: that the increase in stimulus necessary to produce an increase in sensation is not fixed but depends on the strength of the preceding stimulus.
