When physicists at Princeton heard the news, they became a "stirred-up ant heap." Beyond the buzz of the discovery, other repercussions became quickly apparent: Not only did this event, called nuclear fission, create two smaller atoms, but breaking these powerful atomic bonds released a relative...
