A man moves into a n*dist colony. He receives a letter from his mother asking him to send her a current photo of himself in his new location. Too embarrassed to let her know that he lives in a n*dist colony, he cuts a photo in half and sends her the top half.
Later he receives another letter asking him to send a picture to his grandmother. The man cuts another picture in half, but accidentally sends the bottom half of the photo. He is really worried when he realizes that he sent the wrong half, but then remembers how bad his grandmother's eyesight is, and hopes she won't notice.
A few weeks later, he receives a letter from his grandmother. It says... "Thank you for the picture. Change your hair style, it makes your nose look too short!"

Sophie GermainBorn 1 Apr 1776; died 27 Jun 1831 at age 55. French mathematician who is known for her work in number theory and contributions to the applied mathematics of acoustics and elasticity. Germain was self-taught from books, and from lecture notes supplied by male friends attending the Ecole Polytechnique which she, as a woman, was not permitted to attend. Using a male pseudonym, M. LeBlanc, she corresponded with Lagrange who recognised her skill, and subsequently sponsored her work. She accomplished a limited proof of Fermat's last theorem, for any prime under 100 where certain conditions were met. In 1816, she won a prize sponsored by Napoleon for a mathematical explanation of Chladni figures, the vibration of elastic plates. She died at age 55, from breast cancer.« |
