This is a special video presentation that Scientia Salon is publishing at the request of Barry Loewer, Director of the Rutgers Center for Philosophy and the Sciences . It is part of a series of videos published after that came out from the 2014 conference on the philosophy of cosmology held in Tenerife, Spain .
In the video, the author revisits the role of a “low-entropy” past hypothesis in statistical mechanics, and argues that contrary to an apparently-widespread view, (i) the asymmetry in boundary conditions required for statistical mechanics to be derived is not well understood as an entropy constraint; (ii) it is misleading to see the high level of uniformity of the early Universe as a “low-entropy source” for present thermodynamical non-equilibrium.
David Wallace is a philosopher of physics, based in the University of Oxford at Balliol College. He is a member of the Philosophy of Physics group at Oxford, which is one of the largest in the world. Wallace’s original training was in theoretical physics and his current research interests are mostly in the philosophy of physics. He has been particularly active in trying to develop and defend the Everett interpretation of quantum theory (often called the “Many-Worlds Interpretation”); his book on the topic, “The Emergent Multiverse“, was published in June 2012.
