Long-range order, much like action at a distance, remains a bit mysterious. It represents an intermediate regime between perfect periodicity and complete randomness. Voronoi entropy provides a quantitative measure of order in two-dimensional point sets, ranging from S=0 for perfectly… Read More
According to Landauer’s principle, there is energy cost for any exchange of information. Consequently, synchronization of clocks (and in general the introduction of a frame of reference) is an action that itself requires energy. This is often overlooked, and people… Read More
