Decoherence as projection discusses photon polarization as a phenomenon that can only be explained quantum mechanically even at the macroscopic level –
Recently, a friend of mine pointed out a concurrent implementation of Eratosthenes’ prime sieve expressed in google’s Go programming language. I couldn’t resist trying a Haskell version of that same approach.
