Quantum Reality
Jim Baggott’s new book, Quantum Reality, is now out here in US, and I highly recommend it to anyone interested in the issues surrounding the interpretation of quantum mechanics. Starting next week I’ll be teaching a course on quantum mechanics … Continue reading

Funding Priorities
The research that gets done in any field of science is heavily influenced by the priorities set by those who fund the research. For science in the US in general, and the field of theoretical physics in particular, recent years … Continue reading

Guys and Their Theories of Everything
I’m a big fan of Sabine Hossenfelder’s music videos, the latest of which, Theories of Everything, has recently appeared. I also agree with much of the discussion of this at her latest blog posting where Steven Evans writes nobody wants … Continue reading

Twistors and the Standard Model
For the past few months I’ve been working on writing up some ideas I’m quite excited about, and the pandemic has helped move things along by removing distractions and forcing me to mostly stay home. There’s now something written that … Continue reading

Quantization and Dirac Cohomology
For many years I’ve been fascinated by the topic of “Dirac cohomology” and its possible relations to various questions about quantization and quantum field theory. At first I was mainly trying to understand the relation to BRST, and wrote some … Continue reading

(Imaginary) Time Asymmetry
When people write down a list of axioms for quantum mechanics, they typically neglect to include a crucial one: positivity (or more generally, boundedness below) of the energy. This is equivalent to saying that something very different happens when you … Continue reading

Yesterday’s Hype
Every summer CERN runs a summer student programme, designed to bring in a group of students to participate in scientific activities at CERN and provide lectures for them about the basics and latest state of the field of high energy … Continue reading

What is “Spin”?
The explanation for the lack of blogging here the past month is mostly that I haven’t seen any news worth blogging about. It took only a little bit of self-control to not do things like make snarky comments about recent … Continue reading

HEP News
The CERN Council is meeting today and tomorrow, and should approve the long-awaited 2020 update of the European Strategy for Particle Physics. There will be a live webcast of the open part of the Council meeting on Friday. My understanding … Continue reading

HEP Theory Job Situation
Way back in the 1980s and 1990s I was, for obvious personal reasons, paying close attention to the job situation for young HEP theorists. They were not good at all: way more talented young theorists than jobs, many if not … Continue reading
