Abstract

"It is widely believed that the homogeneity of time is the symmetry related by Noether's (first) theorem to the conservation of energy, and indeed that it explains energy conservation. Both claims are questionable, and in particular seemingly hard to reconcile with the modern version of Noether's first theorem due independently to Martínes Alonso (1979) and Olver (1986). The talk is based on: 'Do symmetries ""explain"" conservation laws? ...' arXiv:2010.10909v1"
