There was once a great actor who could no longer remember his lines. After several years of searching, he finally finds a theater where they seem prepared to give him a chance to shine again.
The director says, "This is the most important part, and it has only one line. At the opening you walk on stage carrying a rose. You hold the rose to your nose with just one finger and thumb, sniff the rose deeply and then say the line 'Ah, the sweet aroma of my mistress.'"
The actor is thrilled. All day long before the play, he's practicing his line over and over again. Finally, the time comes. The curtain goes up, the actor walks onto the stage, and with great passion delivers the line, "Ah, the sweet aroma of my mistress."
The theater erupts. The audience is screaming with laughter, but the director is steaming!
"Argh! You idiot!" he cries. "You've ruined me!"
The actor is bewildered, "What happened, did I forget my line?"
"No!" screams the director. "You forgot the rose!"

Charles-Eugène Delaunay

Died 5 Aug 1872 at age 56 (born 9 Apr 1816).French mathematician and astronomer whose theory of lunar motion advanced the development of planetary-motion theories. After 20 years of work, he published two volumes on lunar theory, La Théorie du mouvement de la lune (1860,1867). This is an important case of the three body problem. Delaunay found the longitude, latitude and parallax of the Moon as infinite series. These gave results correct to 1 second of arc but were not too practical as the series converged slowly. However this work was important in the beginnings of functional analysis. Delaunay succeeded Le Verrier as director of the Paris Observatory in 1870 but two years later he and three companions drowned in a boating accident.
