History
This term was coined by Caltech scientist Andrew Ingersoll in a paper that described a model of the atmosphere of Venus. Water vapor initially in the atmosphere of Venus absorbed outgoing radiation which caused the planet to heat and increased water vapor. High abundance of water vapor in the atmosphere allowed it to be photodissociated, with lighter hydrogen gas escaping to space and oxygen reacting with surface rocks. This model is supported by the deuterium/hydrogen ratio on Venus which is 150 times greater than the D/H ratio on Earth.

Famous quotes containing the word history:
“It may be well to remember that the highest level of moral aspiration recorded in history was reached by a few ancient Jews—Micah, Isaiah, and the rest—who took no count whatever of what might not happen to them after death. It is not obvious to me why the same point should not by and by be reached by the Gentiles.”
—Thomas Henry Huxley (1825–95)
“The history of all hitherto existing society is the history of class struggles.”
—Karl Marx (1818–1883)
“Every library should try to be complete on something, if it were only the history of pinheads.”
—Oliver Wendell Holmes, Sr. (1809–1894)
