### Philip was enjoying the second...

Philip was enjoying the second week of a two-week vacation the same way he had enjoyed the first week: by doing as little as possible.
He ignored his wife Paula's not-so-subtle hints about completing certain jobs around the house, but Philip didn't realize how much this bothered her until the clothes dryer refused to work, the iron shorted and the sewing machine motor burned out in the middle of a seam. The final straw came when she plugged in the vacuum cleaner and nothing happened.
Paula looked so stricken that he had to offer some consolation.
"That's OK, darling," Philip said. "You still have me."
Paula looked up at him with tears in her eyes. "Yes, Philip," she wailed, "but you don't work either."

### Gustav Theodor Fechner

Born 19 Apr 1801; died 18 Nov 1887 at age 86. German physicist and philosopher who was a key figure in the founding of psychophysics, the science concerned with quantitative relations between sensations and the stimuli producing them. He formulated the rule known as Fechner's law, that, within limits, the intensity of a sensation increases as the logarithm of the stimulus. He also proposed a mathematical expression of the theory concerning the difference between two stimuli, advanced by E. H. Weber. (These are now known to be only approximately true. However, as long as the stimulus is of moderate intensity, then the laws will give us a good estimate.) Under the name "Dr. Mises" he also wrote humorous satire. In philosophy he was an animist, maintaining that life is manifest in all objects of the universe.
