A New Scientist column entitled "Where does time actually come from?" discusses the recent contribution by Pablo Arrighi and Gilles Dowek from LMF and Amélia Durbec from IEMN, to the somewhat fundamental questions about the nature of Time.
Since the laws of Physics are time-reversible, what makes the difference between past and future? Entropy may increase, but how come it was low to begin with? And by-the-way, what happened even before it was at its lowest? And what if... working with toy model graph dynamics, could suggest simple CompSci answers to big Physics questions?
