What does that one do?
A man entered a pet shop, wanting to buy a parrot. The shop owner pointed out three identical parrots on a perch and said, "The parrot to the left costs 500 dollars."
"Why does that parrot cost so much?" the man wondered.
The owner replied, "Well, it knows how to use a computer."
The man asked about the next parrot on the perch.
"That one costs 1,000 dollars because it can do everything the other parrot can do, plus it knows how to use the UNIX operating system." Naturally, the startled customer asked about the third parrot.
"That one costs 2,000 dollars."
"And what does that one do?" the man asked.
The owner replied, "To be honest, I've never seen him do a thing, but the other two call him boss!"

Adolphe QueteletBorn 22 Feb 1796; died 17 Feb 1874 at age 77. Lambert-Adolphe-Jacques Quetelet was a Belgian astronomer, statistician, mathematician and sociologist whose career began teaching mathematics at the Athenaeum, Brussels (1820), while also pursuing the study of astronomy from 1823. Quetelet was instrumental in setting up, and became the director of, a newly equipped Brussels Royal Observatory (opened 1833). From 1825, he began writing papers on social statistics, and in 1835 gained international recognition for publication of Sur l'homme et le developpement de ses facultés, essai d'une physique sociale. Whereas the normal curve had previously been applied to error correction, Quetelet used it to illustrate a distribution of measured human traits about the central value, giving the concept of the average man at the peak. In this way, for example, he applied a statistical view to the nature of criminal behaviour in society.«Image: from a 1974 Belgian postage stamp. |
