Quantum gunfight

3. February 2010 09:59

There’s a brilliant story on New Scientist today about why you should draw second in a gunfight. The best thing about it is the recollection that Neils Bohr, the father of quantum theory, used to force his colleagues to participate in gunfight experiments:

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.


Turns out Bohr was right: the circuits involved in reacting to a threat work faster than those that are self-stimulated. But it puts a whole new spin on Heisenberg’s troubled relationship with Bohr. Bohr was a big bully, and the man behind the uncertainty principle recalls one discussion over the implications of quantum theory ending “with my breaking out in tears because I just couldn't stand this pressure from Bohr.”

Heisenberg should be glad that quantum theory was invented before paintball – otherwise Bohr really would have given him something to cry about…
