Tough as it is to follow Charli’s excellent post on terrorism, somebody has to do it and so I might as well. If this past ISA is any indication, quantum is a big deal. The panel on Alex Wendt’s new book linking quantum mechanics to the social sciences was standing room only (from what I hear, I could not be there). James Der Derian has Project Q at the University of Sydney. One of the papers I read as a discussant at ISA invoked the term superpositionality, much to my surprise. So, Newtonian World out, Quantum World in (not sure where Einstein fits).
This is all fascinating. Quantum mechanics has been around for a while, and for a while physicists have struggled to reconcile the strange subatomic world, characterized by phenomena like superpositionality (the state or location of a particle are probabilistic and exist in multiple states/conditions at the same time, and according to one interpretation only collapsed to a point upon observation), quantum tunneling (when a particle passes through a barrier without having to surmount it) and quantum entanglement (quantum states of two particles are linked such that changes in one are immediately reflected in the other, regardless of distance), with the macroscopic world we see, which is characterized by none of these things.
