It is not circular logic. My premises are: 1. Classical physics cannot predict the results of at least one physics experiment. This should be uncontroversial because otherwise the field of quantum mechanics wouldn't exist. 2. The results of said experiment can be observed at a macro scale. This should also be uncontroversial because the publication of experimental results is observable at the macro scale. It follows directly from those two premises that there is at least one macro scale phenomenon that classical physics can not predict.
