Abstract In 1918, Emmy Noether published a (now famous) theorem establishing a general connection between continuous ‘global’ symmetries and conserved quantities. In fact, Noether's paper contains two theorems, and the second of these deals with ‘local’ symmetries; prima facie , this second theorem has nothing to do with conserved quantities. In the same year, Hermann Weyl independently made the first attempt to derive conservation of electric charge from a postulated gauge symmetry. In the… Expand
