Mommy has told her little girl all about the making of babies. Little Annie is now silent for a while.
"You understand it now?" Mommy asks.
"Yes," replies her daughter.
"Do you still have any questions?"
"Yes, how about little kittens? How does that work?"
"In exactly the same way as with babies."
"Wow!" the girl exclaims. "My daddy can do ANYTHING!"
RegiomontanusBorn 6 Jun 1436; died 6 Jul 1476 at age 40.German astronomer and mathematician who was chiefly responsible for the revival and advancement of trigonometry in Europe. His book De triangulis omnimodis (1464) is a systematic account of methods for solving triangles. In Jan 1472 he made observations of a comet which were accurate enough to allow it to be identified with Halley's comet 210 years later (being three returns of the 70 year period comet). He also observed several eclipses of the Moon. His interest in the motion of the Moon led him to make the important observation that the method of lunar distances could be used to determine longitude at sea. However, instruments of the time lacked the necessary accuracy to use the method at sea. |
