NotNormallyNormal writes "It appears that quantum mechanics can't be solved with a skateboard. A court case in San Mateo County has a homeless man on trial for attacking another transient. Apparently a discussion between two homeless men about "quantum mechanics and the splitting of atoms" was rudely ended by a third homeless man who joined the conversation and then ended it by hitting one of the other men with a skateboard. It might be hard for the man to claim innocence with there being two external observers knowing that will collapse the wave function. Maybe he was trying to explain how the skateboard could tunnel through his head?"
