So these two men get along well and enjoy a cup of coffee together. This article took a long while to get going but in the end was quite interesting.

I agree that there are problems with mathematics but to throw logic out of the door to fix it sounds a bit extreme. If it just boils down to making the mathematics more flexible that is a different matter but picking and choosing when to be flexible and when not is a bit arbitrary.It doesn't sound right to just pick the mathematics that...


Physics postulates isotropic vacuum for Einstein's elevator (GR) and angular momentum conservation (QFT) through Noether's theorem. Parity is the only non-Noetherian external symmetry. Physics choked on parity (Yang and Lee). Any symmetric body gaplessly dissects into homochiral halves (La Coupe du Roi; Ashtekar and GR). Quantized gravitation is not predictive. Therefore...

A massed sector chiral pseudoscalar vacuum background renders GR and QFT incomplete. Pseudoscalar field...
