Today in Labor History January 31, 1950: President Truman ordered the development of thermonuclear weapons (Hydrogen bombs). The U.S. tested the first thermonuclear weapon in 1952. It was developed by Edward Teller. H-bombs consist of a nuclear fission primary stage, much like older atomic bombs. The fuel for this stage is usually 235U or 239Pu. This is followed by a nuclear fusion reaction using the heavy hydrogen isotope deuterium and tritium. Modern thermonuclear weapons use lithium deuteride. The nuclear fission stage creates a temperature of over 100 million Kelvin (180 million degrees Fahrenheit), flooding the radiation channel with X-rays. The X-ray energy implodes a plutonium spark plug, compressing the secondary stage and driving the plutonium into a supercritical state that drives a fission chain reaction. The fission products heat the thermonuclear fuel to 300 million Kelvin, igniting the fusion reactions.

Retro SciFi of the Week…

Godzilla (1954)

This is the original Japanese version. Shortly after it’s release, a highly censored American version was released in the US and other countries which totally hacked up the film, replacing character- and plot-developing dialogue with bland exposition voiceover.

The American version replaced one of the protagonists with a white guy, cutting in scenes which were produced with lousy sets, poor cinematography and hasty acting which trampled on the carefully crafted pace of the original film. This gave most people an impression that the film was just a B-movie, instead of the well-produced masterpiece which was the original.

If you’ve never seen the original Japanese version, you haven’t seen Godzilla.

(Note: Of course, as with all earlier films, the cinematic techniques of the time were no match to today’s state of the art, so you need to watch it with a different level of suspension of disbelief.)

Here’s a clip from the film that was cut from the American version. (See the rest of this thread for more discussion.)
