It’s amazing what you can learn about capabilities from a picture. Apparently German scientists during ww2 used the diameter of the Hiroshima explosion from the newspapers to calculate the mass of uranium involved.

Hiroshima happened after Germany surrendered so I am curious what you mean. Certainly not nazi scientists.

You can’t tell the mass of the uranium from the size of the explosion unless you already know exact details of the bomb design (in which case you would already know the mass of the uranium).
