Writing in 1976, Weinberg made an interesting observation [1]:
A number of years ago, when I was an in-
structor at Columbia University, I heard a
rumor that Werner Heisenberg and Wolfgang
Pauli, two of the great figures in physics in this
century, had developed a new theory which
would unify the physics of elementary particles.
Thus, you can imagine my excitement when I
received an invitation to attend what was de-
scribed as a secret seminar to be conducted by
Heisenberg and Pauli. On the appointed day, I
was somewhat disconcerted to find some 500
distinguished theoretical physicists attempting to
crowd into the room; however, my enthusiasm
returned when I saw Niels Bohr seated in the
front row. (I had been a graduate student at
Copenhagen and had learned to look on Bohr
as an oracle.) After Heisenberg and Pauli dis-
cussed their theory, Bohr commented on it, con-
cluding that he doubted the theory would be
the great new revolution in physics because it
was not sufficiently “crazy.”
He further adds :
This remark reflects an opinion, very common among
physicists for the past forty years, that the next
significant advance in theoretical physics would
appear as another revolution – a break with the
concepts of the past as radical as the great revo-
lutions of the first third of the twentieth century:
the theory of relativity and the development of
quantum mechanics. That opinion may yet be
proved true, but what has been developing in
the last few years is, in fact, a different sort of
synthesis. There is now a feeling that the pieces
of physics are falling into place, not because of
any single revolutionary idea or because of the
efforts of any one physicist, but because of a
flowering of many seeds of theory, most of them
planted long ago
I like this way of thinking in terms of synthesis. It is closer to how science is done today than giving all the credit to an individual. Weinberg was a fine thinker who deeply thought about physics and its history. This is evident in his writing and talks.
