## Unification, Spinors, Twistors, String Theory

Last month I recorded a podcast with Curt Jaimungal for his Theories of Everything site, and it’s now available with audio here, on Youtube here. There are quite a few other programs on the site well worth watching. Much of … Continue reading

## Spacetime is Right-handed v. 2.0 and Some Notes on Spinors and Twistors

I’ve just replaced the old version of my draft “spacetime is right-handed” paper (discussed here) with a new, hopefully improved version. If it is improved, thanks are due to a couple people who sent helpful comments on the older version, … Continue reading

## Spacetime is Right-handed

I’ve finally managed to write up something short about an idea I’ve been working on for the last few months, so now have a preliminary draft version of a paper tentatively entitled Spacetime is Right-handed. One motivation for this is … Continue reading

## Frenkel on String Theory

Curt Jaimungal’s Theories of Everything podcast has a new episode featuring a long talk with Edward Frenkel (by the way, I’ll be doing one of these next month). A few months ago I wrote about a Lex Fridman podcast with … Continue reading

## Various and Sundry

The math department at Columbia this fall will be hosting three special lecture series, each with some connection to physics (at least in my mind…): Sergiu Klainerman will be lecturing on the proof of nonlinear stability for slowly rotating black … Continue reading

## This Week’s Hype

Nanopoulos and co-authors have predictions from superstring theory that are “in strong agreement with NANOGrav data.” He has been at this now for almost 40 years. See for instance Experimental Predictions from the Superstring from 1985, where the superstring predicted … Continue reading
