Unformatted text preview: Philosophy of Physics An Empirical Approach to Symmetry and Probability Jill North February 13, 2012 Introduction Example: a die, each side should have 1/6 of a chance of showing up o You might think that there can be no chances other than 0 or 1 if the laws are deterministic; or that there are no objective probabilities at all in the world Indifference principle: infer a distribution that is indifferent among the outcomes which, for all we know, could obtain Symmetric probability basically states that theres no reason to believe the chances are tipped in one direction Symmetric probability: classical physics Classical statistical mechanics Boltzmannian framework: different approaches? Phase space (statespace): microstates, macrostates, etc. A probability distribution is placed over the region in phase space corresponding to its macrostate (Lebesque measure) equal probabilities to equal phase space volumes on the standard measure Thermodynamic phenomena thermal equilibrium...
