Last weekend, my family and I saw the movie "Oppenheimer."

It was a little different from what I had expected.

I was expecting a "project management" or "technology" talk, so the politics (post-war red hunts) were a bit heavy.

Well, let's put that aside.

I know much about the Manhattan Project from reading this book and the NHK Special, but I still have questions.

The Trinity test was successful the first time.

Technology experiments usually fail at first. A good example would be "rocket experiments.

It is not an old story of how many rockets humanity has failed to launch in the past, but an ongoing story.

Of course, this mission requires tremendous money and time, and that failure was unacceptable.?Even so, Still, any experiment is doomed to fail.

It is a little hard to believe that the device (bomb) that detonates the atomic bomb, called the "detonation lens," worked the first time.

Furthermore, in the case of the atomic bombings of Hiroshima and Nagasaki, it would have been even more difficult.

Controlling the timing of the detonation of the detonation lens of an atomic bomb thrown up into the air (I checked and found that it requires nanosecond precision) would have required unimaginably tricky technology.

If you expect the movie "Oppenheimer" to be about that kind of "technology," you will be disappointed.

They can't get seven Academy Awards just for that kind of technology.

What shocked me about the movie was that there was a hypothesis that the explosion of the atomic bomb would ignite the atmosphere and burn up the entire earth and that they tested this hypothesis (this does not seem to be fiction).

I had no idea about this hypothesis.

"If they adopted this hypothesis, mankind would have been forced to abandon the idea of having atomic bombs."

When I think about it, I also think, 'That was a shame.

However, when asked if a "world without atomic bombs" would have been "a better world than the one we live in now," I can only answer, "I don't know.

Another thing, which I think is appropriate in light of the knowledge of the time, is that the characters do not seem to fear being "exposed to the atomic bomb.

Well, we learned about the "damages of exposure" to the atomic bombing much later, so in that sense, I think the film is an accurate reflection of its time.
