He who draws last, draws his last breath

摘要

Niels bohr once had a theory on why the good guy always won shoot-outs in Hollywood westerns. It was simple: the bad guy always drew first. That left the good guy to react unthinkingly-and therefore faster. When Bohr tested his hypothesis with toy pistols and colleagues who drew first, he always won.rnAndrew Welchman of the University of Birmingham, UK, has now taken this a step further. Bohr may have won a Nobel prize for his work on quantum mechanics, but it turns out the answer to this puzzle is more complicated than he thought.
