The Constants of Nature are quantities, whose numerical values we know with the greatest experimental accuracy – but about the rationale for those values, we have the greatest ignorance. We might also ask if they are indeed constant in space and time, and investigate whether their values arise at random or are uniquely determined by some deep theory.

The talks are aimed at philosophers of physics but should also be of interest to a wide range of cosmologists. Speakers will introduce the physical constants that define the standard model of particle physics and cosmology together with the data that determine them, describe observational programmes that test the constancy of traditional ‘constants’, including the cosmological constant, and discuss how self-consistent theories of varying constants can be formulated.
