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***

Shigefumi Mori

Born 23 Feb 1951.Japanese mathematician who has made important contributions to the field of algebraic geometry. His major work, in which he proved the existence of minimal models for all three-dimensional algebraic varieties (Jan 1988), has been dubbed Mori's Program. Within ten years since his first published paper, Mori had thereby completed what many said could never be done. In 1979, Mori published his first major results, a proof of the Hartshorne conjecture, which stated that a certain class of algebraic varieties are projective in nature. In other words, these varieties or sets of solutions to given polynomial equations could be described using projective geometry. He was awarded the Fields Medal in 1990 for his work in algebraic geometry.
