Remember how the exact construction of even the WW II-type atom bomb was still a closely-guarded secret, super-duper tip top secret?
...So secret that physicists in a whole bunch of tiny little countries ginned up their own, and some of them didn't get the Cliff Notes to work from, either.
But still, to figure that stuff out, you have to be an Atomic Scientist with a whole country footing the bill, right? Not a truck driver from Wisconsin.
In fact, wrong.
