Like most of biology. An exception for e very rule. Life, uh, finds a way.

Not always. Though near enough to 100% that it counts as such I suppose.

1000 B.C.E. = about 3000 years ago, pretty sure no Romans yet.

Wasn't what I meant. Didn't mean weapons research. Just the concepts of research into the atomic nucleus, first modernish theories of the nucleus etc.

Nuclear research had been going on for decades by then, weapons research not as long(the idea of a neutron chain reaction was only about 10 years old) but preliminary R&D into nuclear weapons was taking place in several nations by 1940.
iirc there was a British commando raid to destroy a heavy water production facility in Norway in '41.

How fast would a mass of U235 have to impact something to achieve a reasonably efficient nuclear detonation?
Presumably the projectile would have to be shaped a certain way. Would a hollow point work?
And if it were filled with heavy hydrogen could we have H bomb level effect from it?

What if pi was exactly 3?
