History
In early research it was noticed that arc discharge devices and some vacuum tube devices such as the dynatron exhibit negative differential resistance effects. Practical and economic devices only became available with solid state technology. The typical true negative impedance circuit—the negative impedance converter – is due to John G. Linvill (1953) and the popular element with negative differential resistance—the tunnel diode – is due to Leo Esaki (1958).

Famous quotes containing the word history:
“American time has stretched around the world. It has become the dominant tempo of modern history, especially of the history of Europe.”
—Harold Rosenberg (19061978)
“While the Republic has already acquired a history world-wide, America is still unsettled and unexplored. Like the English in New Holland, we live only on the shores of a continent even yet, and hardly know where the rivers come from which float our navy.”
—Henry David Thoreau (18171862)
“There has never been in history another such culture as the Western civilization M a culture which has practiced the belief that the physical and social environment of man is subject to rational manipulation and that history is subject to the will and action of man; whereas central to the traditional cultures of the rivals of Western civilization, those of Africa and Asia, is a belief that it is environment that dominates man.”
—Ishmael Reed (b. 1938)
