Today, those few who are still alive are a rare breed. Among them is
Peter Lax
, a 94-year-old mathematics genius and retired professor at New York University, who at the time of the Trinity test was just a 19-year-old corporal stationed at Los Alamos.
Where did the US get uranium for the atomic bomb?
Most of the uranium used during World War II was from the
Congolese mines
, and the “Little Boy” bomb the U.S. dropped on Hiroshima on August 6, 1945 used Congolese uranium. However, the transportation of uranium across the Atlantic Ocean was an arduous task. The journey needed to be quick and secretive.

The two atomic bombs dropped on Japan in 1945 killed and maimed hundreds of thousands of people, and
their effects are still being felt today
.
Can someone survive a nuclear bomb?
Technically,
humans can withstand that much pressure
, but most people would be killed by falling buildings. If you somehow survive all of that, there’s still the radiation poisoning to deal with – and the nuclear fallout.
Can humans survive nuclear war?
But the vast majority of the human population would suffer extremely unpleasant deaths from burns, radiation and starvation, and human civilization would likely collapse entirely.
Survivors would eke out a living on a devastated, barren planet.
