Mommy, my turtle is dead...

"Mommy, my turtle is dead," the little boy, Freddie, sorrowfully told his mother, holding the turtle out to her.
The mother kissed him on the head, then said, "That's all right. We'll wrap him in tissue paper, put him in a little box, then have a nice burial ceremony in the back yard. After that, we'll go out for an ice cream soda, and then get you a new pet. I don't want you...." Her voice trailed off as she noticed the turtle move.
"Freddie, your turtle is not dead after all."
"Oh," the disappointed boy said. "Can I kill it?"

Urbain-Jean-Joseph Le Verrier

Born 11 Mar 1811; died 23 Sep 1877 at age 66. French astronomer who predicted by mathematical means the existence of the planet Neptune. He switched from his first subject of chemistry to to teach astronomy at the Ecole Polytechnique in 1837 and worked at the Paris Observatory for most of his life. His main activity was in celestial mechanics. Independently of Adams, Le Verrier calculated the position of Neptune from irregularities in Uranus's orbit. As Camille Flammarion said, he discovered a planet with the tip of his pen, without any instrument other than the strength of his calculations alone. In 1856, the German astronomer Johan G. Galle discovered Neptune after only an hour of searching, within one degree of the position that had been computed by Le Verrier, who had asked him to look for it there. In this way Le Verrier gave the most striking confirmation of the theory of gravitation propounded by Newton. Le Verrier also initiated the meteorological service for France, especially the weather warnings for seaports. Incorrectly, he predicted a planet, Vulcan, or asteroid belt, within the orbit of Mercury to account for an observed discrepancy (1855) in the motion in the perihelion of Mercury.
