I have been out of high-energy physics for some twenty years, and to get myself back into the mood of a particle physicist, I would like to quote some recent remarks by Carlo Rubbia:

I've never heard it expressed so well, but I'd like to add that particle physics has always been done by a triad of equally important professionals: accelerator builders, experimental physicists, and theoretical physicists. I'll have some comments at the end on how I hope the members of the triad will interact in the future. I have been a member of the first two categories, but never of the third.

My ten years in the bubble-chamber trenches (also discussed by Peter Galison in Chapter 14), the most exciting period in my life, started at the 1953 Washington meeting of the American Physical Society (APS), when I met Donald Glaser. He showed me his first cosmic-ray tracks in a tiny bubble chamber (1 × 2 cm) filled with ether. I had been unsuccessfully racking my brain to find an appropriate detector for the Bevatron, which was about to be turned on. It was immediately clear to me that Glaser's chamber filled the bill exactly – if it could be made to work with liquid hydrogen, and if it would operate in large enough sizes.
