“United States ushered in the nuclear age with the detonation of the world’s first nuclear explosive device”

Unfortunately we weren’t he first. Japan tested their device in February 1945 in northern Korea. Lucky for us they used up all their fissionable material and couldn’t go on to a working deployable device.

Proof please. I can go to Trinity site today (if they’d let me), pick up a piece of trinitite, test the beta emissions, and determine the date (within a year) of the blast. Where is the Japanese blast site?

Me thinks you are believing some post-revisionist history.

A nuclear explosive leaves a human-timeframe-defined indelible mark on the planet.

I have heard of no such thing for Japan.

Additionally, the Japanese didn’t have the industrial know how at the time, besides the physics knowledge.

Sciences that did not exist before, outside of nuclear physics, were established, and the technologies based on that science were fully matured within the project scope, many related to the refinement of Uranium and extraction of fissile isotope U235.

Japan had neither the resources, treasure, or industrial knowledge to match that.

At the time, that was the limiter. Most knew it could be done, but no one knew how to make enough material to make it happen for a basic gun style bomb.

I am fairly well versed in these things, having worked with nuclear materials, and I didn’t know anything about this so I would be interested as well.

I will keep an open mind, because I sure as heck don’t know anything close to everything...:)

Interesting. would you share a source ("sauce") for that info?
