...began listening for the faint echoes of its own radar signals to earth. On the igth echo-800 ft. above the rooftops of Hiroshima-a powder charge sent one uranium mass bullet-ing through a hollow shaft into the other mass. In one fifteen-hundredth of a microsecond, fission began. In that dreadful instant a city died, and 70,000 of its inhabitants...
Another possibility is a rocket engine that uses nuclear fusion of heavy hydrogen instead of fission of uranium. No controlled fusion reactor has yet been constructed for any purpose, and making a light one for rockets will be much harder than making a heavy one for power stations. But the nuclear enthusiasts are not discouraged. Deuterium is cheap, they say, and even if the entire stock were shot out of the nozzle, the fuel for a flight would cost only...
...factual letter to Joint Committee on Atomic Energy Chairman Carl Durham of North Carolina. "Atomic bombs," said Strauss, "are only taken from stockpiles for purposes of routine inspection or for modification or improvement. No material is 'inserted' in bombs for the purpose of increasing the amount of fission products or to add to the total fallout." At that, Anderson arose wrathfully on the Senate floor, declared that Strauss "in effect four times calls me a liar...
...believe we are the only humans in all the cosmic world? Astronomer Struve says: "It is perfectly conceivable that some intelligent race meddled once too often with nuclear laws and blew themselves to bits." This is just about what may hit us-if we keep monkeying around with nuclear fission...
...have exploded devices equal to 3,000,000 tons of high explosives . . . On the assumption that I am right in thinking we are not in front in this race, we should not forget that our tests are more important to us than theirs are to them." Two Kinds of Fission. But nearly every political poll shows the Tories trailing Labor in popularity, and odds are that after the next general election, Britain will have a Labor government. Wrote London's conservative Daily Telegraph last week: "These foolish concessions might lessen the danger of political fission within the Labor Party...
