That sound, emitted by the Soviet satellite Sputnik 1 , marked the dawn of a new era in human history and ignited one of the most intense technological rivalries of the 20th century. Over the next three years, the United States and the Soviet Union transformed scientific ambition into geopolitical competition, reshaping education, defense, and global prestige. Sputnik and the Shock of 1957 The launch of Sputnik 1 was not entirely unexpected in scientific circles. Both the United States and the Soviet Union had announced plans to launch artificial satellites as part of the International Geophysical Year (1957–1958), a global scientific initiative. However, few anticipated that the Soviets would achieve orbit first—and with such apparent ease. Weighing about 83.6 kilograms (184 pounds), Sputnik 1 w...

But humans have been obsessed with this number since we first figured out that round things roll better than square ones. The Babylonians and Egyptians were the first to take a crack at it aro...
