He presented the idea to Edward Teller, who realized that radiation compression would be both faster and more efficient than mechanical shock.
12.
In January 1951, Ulam had another idea : to channel the mechanical shock of a nuclear explosion so as to compress the fusion fuel.
13.
"' G-Shock "'is a line of watches manufactured by Casio, designed to resist mechanical shock and vibration.
14.
Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical shock, stress or impact, and many other causes.
15.
They are thought to be caused by the rupture of small capillaries under the skin, either from the lightning current or from the mechanical shock wave.
16.
"' Shock resistant "'is a common mark stamped on the back of wrist watches to indicate how well a watch copes with mechanical shocks.
17.
Military Specification "'MIL-S-901D "'is a military specification for High Impact mechanical shock which applies to equipment mounted on ships.
18.
Mechanical shock forced the oxygen valves closed on the number 1 and number 3 fuel cells, leaving them operating for only about three minutes on the oxygen in the feed lines.
19.
Almost immediately, Teller saw its merit, but noted that soft X-rays from the fission bomb would compress the thermonuclear fuel more strongly than mechanical shock and suggested ways to enhance this effect.
20.
The name referred to the concept that the system would be so accurate and free from the effects of mechanical shocks and jarring that it would not require any other form of " fixing " in flight.
