Quantum mysteries explained in digestible form

Abstract

Years ago, Itamar Pitowski asked two relevant questions: Why microphysical (quantum) phenomena and classical phenomena differ in the way they do? and, what kind of explanation could qualify as a reasonable one? I argue that both questions can be answered by the comparison of quantum phenomena with some features of vectors in real space. In particular, I show how violation of Bell's inequalities, Teleportation, Kochen-Specker and Greenberger-Horne-Zeilinger theorems can be understood in terms of vectors. This does not mean that the difference between quantum and classical phenomena is illusory. This means that vectors are stranger objects that they may seem to be at first sight.
