...beginning of 1968, I felt a growing compulsion to speak out. I was influenced by my life experience and a feeling of personal responsibility, reinforced by the part I'd played in the development of the hydrogen bomb, the special knowledge I'd gained about thermonuclear warfare, my bitter struggle to ban nuclear testing and my familiarity with the Soviet system. My reading and discussions with a fellow scientist had acquainted me with the notions of an open society, convergence and world government. I hoped that these notions might ease the tragic crisis of our age. In 1968 I took...
Except for the presence of a visitor, it was just another dry run for doomsday. A captain and a first lieutenant of the Soviet Strategic Rocket Forces simultaneously turned two keys that would, in wartime, send hurtling toward the U.S. an SS-19 ballistic missile with six independently targeted thermonuclear warheads. Watching from a corner of the cramped underground control center was a tall, droll Yankee naval officer who describes himself as a "country boy from Oklahoma": Admiral William J. Crowe, 64, Chairman of the U.S. Joint Chiefs of Staff and the highest-ranking American military official ever to visit...
...shrimp and other creatures that dig into the bottom and spread the substances through digestion and excretion. Though ocean sediment generally accumulates at a rate of about one-half inch - per thousand years, Biogeochemist John Farrington of the University of Massachusetts at Boston cites discoveries of plutonium from thermonuclear test blasts in the 1950s and 1960s located 12 in. to 20 in. deep in ocean sediment. Thus contaminants can conceivably lie undisturbed in the oceans indefinitely -- or resurface at any time...
Twenty-five years after the Crisis, a large number of new writing and scholarly meetings have commemorated the world's closest brush with thermonuclear war. Even in 1988, the Cuban Missile Crisis held its own as a key factor in the debate over strategic issues and superpower relations--even to the point of coloring current arguments over the INF and START treaties. Politicians, scholars, and journalists have turned to the Crisis to draw out lessons about nuclear weapons, diplomacy, and crisis management. The publication of surprising evidence in this winter's International Security--a transcript of secret tapes which recorded...
...spawned this type of supernova. One hypothesis: SK-69 202, like other stars in the LMC, contained relatively little metal, which theorists now think may keep the outer shell of even older stars from expanding fully, thus making it glow blue rather than red as it plunged toward its thermonuclear crisis. Said University of Chicago Astrophysicist David Schramm: "It's clear that while the core of the star is understood well, the surface...
