History
At the time quantum mechanics was developed, physicists attempted to extend its range of application by formulating versions of the Schrödinger equation that were compatible with special relativity.
The first such equation was discovered by Erwin Schrödinger himself; however, he realized that this equation, now called the Klein–Gordon equation, gave incorrect results when used to calculate the energy levels of hydrogen. Schrödinger discarded his relativistic wave equation, only to realize a few months later that its non-relativistic limit (what is now called the Schrödinger equation) was still of importance.

Famous quotes containing the word history:
“The history of any nation follows an undulatory course. In the trough of the wave we find more or less complete anarchy; but the crest is not more or less complete Utopia, but only, at best, a tolerably humane, partially free and fairly just society that invariably carries within itself the seeds of its own decadence.”
—Aldous Huxley (1894–1963)
“Well, for us, in history where goodness is a rare pearl, he who was good almost takes precedence over he who was great.”
—Victor Hugo (1802–1885)
“History, as an entirety, could only exist in the eyes of an observer outside it and outside the world. History only exists, in the final analysis, for God.”
—Albert Camus (1913–1960)
