"During this period I attended two sessions of the Michigan summer school at which Schwinger (1948) and Feynman (1949) described their respective reformulations of QED. Schwinger’s was deeper and more complete while Feynman’s was easier to use but at that time incomplete. One may give a feeling for the impact of Schwinger by quoting Dyson who wrote home that ”in a few months we shall have forgotten what pre-Schwinger physics was like.” Bethe at that time described this period as the most exciting in physics since the great days of 1925-30 when quantum mechanics was being discovered."
"For two years in the late 1950s I was a postdoc at Harvard. Julian Schwinger was the leading light in theoretical physics at the time. We, the postdocs and junior faculty, audited whatever course he happened to be teaching. The material was always original. The lectures were on Wednesdays, and afterward the small group of us would have lunch with Schwinger at Chez Dreyfus in Cambridge. We would be joined by another small group from MIT that included Vikki Weisskopf. If Schwinger had any new ideas, he would try them out on Weisskopf. As it happened on this occasion, he had developed a “theory of everything.” Some of this theory survives in the work of other people. In 1962, he published a paper on “Gauge invariance and mass.”9 … In it he raised the question of whether one could have a massive vector meson in a theory that had an underlying gauge invariance. This possibility … inspired P. W. Anderson to use these ideas in condensed matter physics.10... 9 J. Schwinger, “Gauge invariance and mass,” Phys. Rev. 125, 397–398 1962 . 10 P. W. Anderson, “Plasmons, gauge invariance and mass,” Phys. Rev. 130, 439–442 1963."
"Is the purpose of theoretical physics to be no more than a cataloging of all the things that can happen when particles interact with each other and separate? Or is it to be an understanding at a deeper level in which there are things that are not directly observable (as the underlying quantized fields are) but in terms of which we shall have a more fundamental understanding?"
"Perhaps the most important contribution to science that the Royal Society has made in its three centuries of existence is its early role in publishing Newton's masterful account of his discoveries: Mathematical Principles of Natural Philosophy—the Principia."
"If my history lesson has done nothing else, it should have reminded you that, during any given period in the evolving history of physics, the prevailing, main line, climate of opinion was likely as not to be wrong, as seen in the light of later developments. And yet, in those earlier times, with relatively few individuals involved, change did occur, but slowly... What is fundamentally different in the present day situation in high energy physics is that large numbers of workers are involved, with corresponding pressures to conformity and resistance to any deflection in direction of the main stream, and that the time scale of one scientific generation is much too long for the rapid pace of experimental discovery. I also have a secret fear that new generations may not necessarily have the opportunity to become familiar with dissident ideas."
"Time appears in quantum mechanics as a continuous parameter which represents an abstraction of the dynamical role of the measurement apparatus. The requirement of invites the extension of this abstraction to include space and time coordinates. The implication that space-time localized measurements are a useful, if practically unrealizable idealization may be incorrect, but it is a grave error dismiss the concept on the basis of a priori notions of measurability."
"I was guilty of judging capitalism by its operations and socialism by its hopes and aspirations; capitalism by its works and socialism by its literature."
"As Adolf Berle, a fellow cold warrior, once remarked, 'Being vindicated by history is cold comfort.' For one thing, the political scars of those with whom one has polemicized seem more long-lasting and painful than their memories of the political issues that gave rise to them. And yet indifference to the political life of one's times I deem a flagrant expression of moral irresponsibility. Those who profess such indifference owe the intellectual and cultural freedoms in which they luxuriate to the commitment and sacrifices of others."
"To me, [it's] extremely interesting that men, perfectly honest, enthusiastic over their work, can so completely fool themselves."
"History proves abundantly that pure science, undertaken without regard to applications to human needs, is usually ultimately of direct benefit to mankind. Within recent years it has become possible for purely scientific work of this character to be carried out with the support of industries, which are, of course, primarily interested in the commercial applications. The scientist who works in this way is frequently especially fortunate in that he not only derives the satisfactions which are characteristic of scientific work in general, but is able to see that many of his results are almost immediately put into a form which directly benefits mankind. Happy indeed is the scientist who not only has the pleasures which I have enumerated, but who also wins the recognition of fellow scientists and of the mankind which ultimately benefits from his endeavors. To my mind, the most important aspect of the Nobel Awards is that they bring home to the masses of the peoples of all nations, a realization of their common interests. They carry to those who have no direct contact with science the international spirit."
"Science, almost from its beginnings, has been truly international in character. National prejudices disappear completely in the scientist’s search for truth. Medicine also disregards national boundaries. And literature frequently rises to heights that make it international. The scientist is motivated primarily by curiosity and a desire for truth. His attitude is objective rather than subjective. In his work he finds great satisfaction in discovering new facts or new relationships between known facts, but even greater pleasure is derived from seeing his results incorporated into the body of scientific knowledge and from seeing them willingly used by others in the further development of science."
"In general, the rate of evaporation (m) of a substance in a high vacuum is related to the pressure (p) of the saturated vapor by the equation m=\sqrt{\frac{M}{2\pi RT}}p. Red phosphorus and some other substances probably form exceptions to this rule."
"I want some red roses for a blue lady. Mister Florist, take my order please. We had a silly quarrel the other day; I hope these pretty flowers chase her blues away."
