Uranium cubes point to a key shortfall in Germany’s nuclear project

Uranium cubes are offering clues about why Germany’s nuclear project failed.

Calculations suggest Heisenberg underestimated the materials needed for the project.

Heisenberg was associated with the German effort, though the available information gives no further details about his role.

The finding points to a possible shortfall in required materials as a factor in the project’s failure.

That matters because it helps explain why the effort did not succeed.

No further steps or plans are specified.
