After getting disillusioned with this research program and after the rise of a convincing alternative for the gauge idea by translating it to the phase of wave functions and spinor f

On Empirical Equivalence and Dualitylent. The judicious reading is straightforward, but leads to the surprising conclusion that very different-looking theories can have equivalent empirical content. And thus it shows how a widespread scientific practice, of interpreting duals as empirically equivalent, can be understood by a thus-far

Gauge Is More Than Mathematical Redundancy-invariant variables of the two subsystems have . information than the gauge-invariant variables of the original system; the missing information regards degrees of freedom that express relations between the subsystems. All this shows that gauge invariance is a formalization of the relational nature

Reichenbach, Weyl, Philosophy and Gaugee and time. This philosophical stance of Weyl’s has received considerable attention in recent years and has been favorably compared and contrasted with the “logical-empiricist” approach of Reichenbach, Weyl’s contemporary who wrote extensively about relativity and the philosophy of space and time.

Autobiography

Hermann Weyl, the Gauge Principle, and Symbolic Construction from the “Purely Infinitesimal”iscovery”: imposed in 1918 on philosophical grounds by Hermann Weyl, it led to a purely formal unification of Einstein’s gravitational theory and electromagnetism. This achievement prompted Weyl’s purely mathematical turn in 1925–6 to Lie theory and of course Lie groups and Lie algebras play promine
