Job Interview

Reaching the end of a job interview, the Human Resources Person asked a young Engineer fresh out of MIT, "And what starting salary were you looking for?"
The Engineer said, "In the neighbourhood of $125,000 a year, depending on the benefits package."
The interviewer said, "Well, what would you say to a package of 5-weeks vacation, 14 paid holidays, full medical and dental, company matching retirement fund to 50% of salary, and a company car leased every 2 years say, a red Corvette?"
The Engineer sat up straight and said, "Wow! Are you kidding?"
And the interviewer replied, "Yeah, but you started it."

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.
