Quotations for Today
"I have seized the light. I have arrested its flight." - Louis Daguerre (born 18 Nov 1787)

"And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right." - American astronaut in the quiz below (born 18 Nov 1923)

"I accept extinction as best explaining disjoined species. I see that the same cause must have reduced many species of great range to small, and that it may have reduced large genera to so small, and of families." - Asa Gray, American botanist (born 18 Nov 1810) 

QUIZ
Births
Born 18 Nov 1923, this American was his country's first man in space and one of only 12 humans who walked on the Moon. Named as one of the nation's original seven Mercury astronauts in 1959, he became the first American into space on 5 May 1961, riding a Redstone rocket on a 15-minute suborbital flight.
Can you name this astronaut?
Louis Daguerre, born 18 Nov 1787, was a French painter and physicist who invented the the first practical process of photography. Though the first permanent photograph from nature was made in 1826/27 by Joseph-Nicéphore Niepce of France, it was of poor quality and required about eight hours' exposure time. Daguerre's new process was also notable because the exposure time was shorter.
What exposure time did a daguerrotype require?
Deaths
Niels Henrik David Bohr (1885-1962) was the physicist who was the first to apply the quantum theory, which restricts the energy of a system to certain discrete values, to the problem of atomic and molecular structure. He developed the so-called Bohr theory of the atom.
What was this scientist's nationality at birth?
Walther Hermann Nernst (1864-1941) was a German scientist who showed that it is possible to determine the equilibrium constant for a chemical reaction from thermal data, and in so doing he formulated what he himself called the third law of thermodynamics.
What was his law of thermodynamics?
Events
On 18 Nov of a certain year, the first telephone in the U.S. with push buttons instead of a rotary dial was placed in commercial service in Carnegie and Greensburg, Pa. This was a Touch-Tone telephone with 10 push buttons, 
In what decade was this telephone installed?
On 18 Nov 1883, standard time in the U.S. went into effect at noon for the first time. The system adopted was first proposed by Charles F. Dowd (1825 - 1904), a school principal in New York state. North America was divided into four time zones, fifteen degrees of longitude, and one hour of "standard time" apart. 
What business association implemented this standard time?
