International Geophysical Year
The International Geophysical Year (IGY) was an international scientific project that lasted from July 1, 1957, to December 31, 1958. It marked the end, after Joseph Stalin's death, of a long period during the Cold War when scientific interchange between East and West was seriously interrupted. 67 countries participated, although one notable exception was mainland China, which was protesting against the participation of the Republic of China (Taiwan). East and West agreed to nominate the Belgian Marcel Nicolet as secretary general of the associated international organization.
The IGY encompassed eleven Earth sciences: aurora and airglow, cosmic rays, geomagnetism, gravity, ionospheric physics, longitude and latitude determinations (precision mapping), meteorology, oceanography, seismology and solar activity.
Both the Soviet Union and the U.S. launched artificial satellites for this event; the Soviet Union's Sputnik 1 October 4 1957 was the first successful artificial satellite. Other significant achievements of the IGY included the discovery of the Van Allen radiation belts and the discovery of mid-ocean submarine ridges, an important confirmation of plate tectonics. Also detected was the rare occurrence of hard solar corpuscular radiation that could be highly dangerous for manned space flight.

Famous quotes containing the word year:
“I remember my youth and the feeling that will never come back any more—the feeling that I could last for ever, outlast the sea, the earth, and all men; the deceitful feeling that lures us on to joys, to perils, to love, to vain effort—to death; the triumphant conviction of strength, the heat of life in the handful of dust, the glow in the heart that with every year grows dim, grows cold, grows small, and expires—and expires, too soon, too soon—before life itself.”
—Joseph Conrad (1857–1924)
