  1. Reversing the arrow of time.Bryan W. Roberts - 2022 - Cambridge: Cambridge University Press.
    'The arrow of time' refers to the curious asymmetry that distinguishes the future from the past. Reversing the Arrow of Time argues that there is an intimate link between the symmetries of 'time itself' and time reversal symmetry in physical theories, which has wide-ranging implications for both physics and its philosophy. This link helps to clarify how we can learn about the symmetries of our world, how to understand the relationship between symmetries and what is real, and how to overcome (...)

  2. The gauge argument: A Noether Reason.Henrique Gomes, Bryan W. Roberts & Jeremy Butterfield - 2022 - In James Read & Nicholas J. Teh (eds.), The physics and philosophy of Noether's theorems. Cambridge: Cambridge University Press. pp. 354-377.
    Why is gauge symmetry so important in modern physics, given that one must eliminate it when interpreting what the theory represents? In this paper we discuss the sense in which gauge symmetry can be fruitfully applied to constrain the space of possible dynamical models in such a way that forces and charges are appropriately coupled. We review the most well-known application of this kind, known as the 'gauge argument' or 'gauge principle', discuss its difficulties, and then reconstruct the gauge argument (...)
