Theoretical particle physicist, University professor, book author, and sometimes blogger. Now a Department Chair at USC!

This book by this year’s Nobel laureate Francis Halzen is very popular - you could see it was used a lot! I have a collection of physics books signed by my colleagues. It all started with a curious incident when I started my position at Cornell many years ago… 🧪

Nobel Week is upon us, with the 2026 Nobel Prize in Physics being awarded on Tuesday, October 6th. This year, instead of asking you for predictions (my pick is Aharonov and Berry), I asked several AI models what they “think.” Here are the results: 🧪

An interesting analysis of parallels between the crisis of US federal funding for physics in the late 1960s and today. The article claims particle physics took the heaviest hit from funding cuts, with several accelerator projects canceled. [cont.] 🧪 physicstoday.aip.org/features/the...

The last crisis of US physics

At the end of the turbulent 1960s, the postwar funding boom in US physics came to a crashing halt. The lessons learned then may be helpful to today’s physicists.

Fun fact from math. There are weird numbers (official name) which are natural numbers whose sum of proper divisors is greater than the number itself, but no subset of those divisors adds up to the number (I.e., they are abundant but not semiperfect). The smallest weird number is 70. 🧪

The premise, style, and even the perceived timing of Michael Kratsios’ 2026 paper, "Science: A New Golden Age," invites a comparison with Vannevar Bush's classic "Science, the Endless Frontier," written in 1945, which established the US science funding doctrine. 🧪

Happy Independence Day! I'd like to take this opportunity to emphasize that our nation's 250-year resilience is rooted in forward-thinking investments in science, research, and development, with a triad of fundamental science, applied science, and engineering propelling our country's advancement. 🧪

Frank Avignone is a great scientist who made our department into a research powerhouse, and he is still very active in research and departmental life. I am fortunate to have him as a colleague. 🧪 www.sc.edu/uofsc/posts/...

Big Bang Theory

Frank Avignone has been fascinated by physics longer than most people have been alive, an intense curiosity that began in the waning days of World War II. Now, more than six decades after being recrui...

…and we're off to a good start for the 5th International Conference on Charged Lepton Flavor Violation (CLFV 2026) at the University of Rome La Sapienza! It’s great to be here in Rome - remembering that the Mu2e experiment at Fermilab will start taking data soon. 🧪

We are off to a good start with the XVI International Conference on Beauty, Charm, and Hyperons in Hadronic Interactions (BEACH 2026) in beautiful Florence; it's great to see old friends and listen to great talks. 🧪

This tape contains Paul Dirac’s lecture (yes, that Paul Dirac, one of the founders of quantum mechanics) at the University of South Carolina. This tape is also legendary; it has been missing for the past 32 years! And guess what: Prof. Frank Avignone found it today! Now we need to digitize it! 🧪

The rain it raineth on the just And also on the unjust fella; But chiefly on the just, because The unjust steals the just’s umbrella. Lord Bowen Равно На честных и бесчестных льется Господень дождь с небесной высоты… Но честным все же больше достается! Бесчестные Крадут у них зонты!

We are introducing Darden Fellows in the Department of Physics & Astronomy, University of South Carolina: senior physics majors serving as peer mentors to their freshman and sophomore colleagues, sharing advice, etc. Do you have similar initiatives? Do they work well at your institution? 🧪

Antimatter in motion! The BASE experiment at CERN literally put antimatter (92 antiprotons) the antiparticles of a hydrogen nucleus, on a truck and moved it across the CERN site. I find it amusing that, at some point, you could order delivery of antiprotons if your experiment needs them! 🧪

BASE experiment at CERN succeeds in transporting antimatter

Today, in a world first, a team of scientists from the BASE experiment at CERN successfully transported a trap filled with antiprotons in a truck across the Laboratory’s main site. The team managed to...

I had a great time at the Astronomy on Tap event at Tin Roof yesterday. There was a very good turnout, a responsive crowd, and good food. People said they will be back for the next installment! 🧪

So, is it more than rumors? Does anyone have something in writing regarding the DOE Nuclear Theory budget? What about High Energy? Why is it happening? The Nuclear Theory budget is tiny compared to other items in the government budget… 🧪

I just received a message from the Department of Energy, my main federal sponsor. There is a strategic realignment that unites the Office of High Energy Physics and the Office of Nuclear Physics. What do you think will happen to the overall level of funding? 🧪
