I took freshman physics from Lowell Brown in 1974 in a small honors class.
I was the only passing student that was not the son of a physics professor.
He was always yelling at me, "I am leaving.You think about it until I get back."

I saw him on TV and the moderator would not let him use the word "quark".


Then in 1994 he wrote the definitive book on quantum field theory.
