In this note the analysis is sharpened. A conjecture of Heisenberg that volume is quantized is shown to be a consequence of the second quantization of gauge fields. A way to generalize the equations of physics to include the Planck length is indicated.7 pagesHigh Energy Physics - TheoryA fresh look at the Bohr-Rosenfeld analysis and a proof of a conjecture of Heisenbergtext
