    My name is James Bjorken, known in the physics community as bj. I retired from a theoretical physics staff position at the Stanford Linear Accelerator Center (SLAC) in 1998. Since then, my physics interests have mostly been focused on the problem of dark energy.

    This website will contain, for the most part, a collection of notes in pdf form documenting work done since retirement. They are at present being placed on this site, along with introductory material.

    If is my hope that these notes may stimulate visitors to take these raw ideas, run with them , and either improve on them or criticize them to death. I am not very sensitive to intellectual property issues, other than direct plagiarism and/or quotation of this material taken out of context, to attack me or these ideas.

I met him briefly when I was a summer student at Fermilab.

Nice article. Pretty amazing Physicist in pretty amazing times...

This part of the talk has to do with belief systems in science. I recall that in the 1960s people would ask me, “Do you believe in quarks?” These people were physicists! As best as I can recall, my reply was, “That is a religious question, not a scientific one. What do you mean?”
 
I am sad. I knew bj from his time at Fermilab. He would host grad school cookouts in the summer. (The grad students were guests, not the entrre). He came to Fermilab around the time his wife, Joanie passed away.

He got me through field theory with the advice "Always calculate ratios. You'll make the same mistake in the numerator as the denominator and you'll be fine." True that.

I also had the privilege of working closely with two-thirds of his former students.
 
Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
