Enter a Password

A woman was helping her husband set up his computer, And at the appropriate point in the process. She told him that he would now need to enter a password, something he could remember easily and will use each time he has to log on.
The husband was in a rather amorous mood and figured he would try for the shock effect to bring this to his wife's attention. So, when the computer asked him to enter his password,
He made it plainly obvious to his wife that he was keying in....
P... E... N.... I... S...
His wife fell off her chair laughing when the computer replied:
***PASSWORD REJECTED. NOT LONG ENOUGH***

Charles-Eugène Delaunay

Died 5 Aug 1872 at age 56 (born 9 Apr 1816).French mathematician and astronomer whose theory of lunar motion advanced the development of planetary-motion theories. After 20 years of work, he published two volumes on lunar theory, La Théorie du mouvement de la lune (1860,1867). This is an important case of the three body problem. Delaunay found the longitude, latitude and parallax of the Moon as infinite series. These gave results correct to 1 second of arc but were not too practical as the series converged slowly. However this work was important in the beginnings of functional analysis. Delaunay succeeded Le Verrier as director of the Paris Observatory in 1870 but two years later he and three companions drowned in a boating accident.
