A brief history of the atomic bomb


H.G. Wells’ “The World Set Free” imagined a bomb of terrifying, absolute power: a uranium-based hand grenade “that would explode indefinitely.” And the fantasy writer wasn’t so far from reality – the beginnings of the atomic bomb came only two and a half decades later. Atomic bombs have only been used twice in war. But with current tensions between the U.S. and North Korea escalating, it’s worth asking how we got here.
