Consider a non-local variable, that is a property associated with quantum state(s) of several particles distributed in space. Can we measure such variables instantaneously, that is in a space-like setting (without communicating classically between the sites)? Relativistic Causality imposes certain restrictions on what can be measured, but (perhaps surprisingly) allows some flexibility. In this talk I will present a brief review of some historic and (relatively) recent developments and discuss interesting concepts and ideas which arise along the way.
