A wife is having sex with her husband's best friend one day. Soon the phone rings, so she answers it.
"Yes... uh, huh... OK... yes... bye."
Her husband's best friend says: "Who was it?"
"That was my husband," she replied.
The man jumped out of bed, and tried to put on his clothes in a hurry.
"Relax," said the wife. "He just called to tell me he was out playing golf with you"
Nasir ad-Din al-TusiDied 26 Jun 1274 at age 73 (born 18 Feb 1201).Muhammad ibn Muhammad ibn al-Hasan al-Tusi was a Persian philosopher, scientist, mathematician and astronomer who made outstanding contributions in his era. When The Mongol invasion, started by Genghis Khan, reached him in 1256, he escaped likely death by joining the victorious Mongols as a scientific advisor. He used an observatory built at Maragheh (finished 1262), assisted by Chinese astronomers. It had various instruments such as a 4 metre wall quadrant made from copper and an azimuth quadrant which was Tusi's own invention. Using accurately plotted planetary movements, he modified Ptolemy's model of the planetary system based on mechanical principles. The observatory and its library became a centre for a wide range of work in science, mathematics and philosophy. He was known by the title Tusi from his place of birth (Tus). |
