The preceding collection of stories about Einstein the young boy demonstrates the remarkable extent to which his most characteristic personal traits were native rather than acquired.
The ultimate unification of weak and electromagnetic interactions has probably not yet been achieved, but a solid beach-head appears to have been established in terms of local non-Abelian gauge theories with spontaneous symmetry breakdown. As a result, it is now widely believed that weak interactions are mediated by massive vector mesons. Current expectations are that such mesons will be observed within the decade. It is widely believed that strong interactions are also mediated by local non-Abelian gauge fields. Their symmetry is supposed to be unbroken so that the corresponding vector mesons are massless. The dynamics of these 'non-Abelian photons' are supposed to prohibit their creation as single free particles. The technical exploration of this theory is in its early stages.
The rule of the game was never assume that anybody, however honorable, would be able to stand up under torture. If Mr. X, who knew where I was, was caught for some reason, I should move.
Promising steps have been made toward grand unification, the union of weak, electromagnetic, and strong interactions in one compact, non-Abelian gauge group. In most grand unifies theories the proton is unstable. News about the proton's fate is eagerly awaited at this time. Superunification, the union of all four forces, is the major goal. Some believe that it is near and that supergravity will provide the answer. Others are not so sure.
Some years ago John Kenneth Galbraith wrote in an essay on his efforts at writing a history of economics: 'As one approaches the present, one is filled with a sense of hopelessness; in a year and possibly even a month, there is now more economic comment in the supposedly serious literature than survives from the whole of the thousand years commonly denominated as the Middle Ages ... anyone who claims to be familiar with it all is a confessing liar.' I believe that all physicists would subscribe to the same sentiments regarding their own professional literature. I do at any rate.
All modern work on unification may be said to represent a program of geometrization that resembles Einstein's earlier attempts, although the manifold subject to geometrization is larger than he anticipated and the quantum framework of the program would not have been to his liking.
One of the absolute rules I learned in the war was, don't know anything you don't need to know, because if you ever get caught they will get it out of you.
Of course, relative citation frequencies are no measure of relative importance. Who has not aspired to write a paper so fundamental that very soon it is known to everyone and cited by no one?
Once I even took the train to Utrecht, forty miles from Amsterdam, with my yellow star, this star which I still have. Why did I go? I just wanted to visit some friends. I was a little bit crazy, a little bit insane.
A number of current theoretical explorations will turn out to be passing fancies ...
Deliberately or not, every author is of course present in every book he or she writes - even in a scientific text.
One of the things I learned, one of the strangest things, is how to think. There was nothing else to do. I couldn't see people, or go for a walk in the forest. All I had was my head and my books, and I thought a lot.
To make a discovery is not necessarily the same as to understand a discovery. Not only Planck but also other physicists were intially at a loss as to what the proper context of the new postulate really was.
