摘要:

On Monday, April 22, 1963, some five months after the death of Niels Bohr, the American Physical Society held a special session in his memory as part of the Society's spring meeting in Washington, D.C. Four of Professor Bohr's friends and former colleagues, J. Rud Nielsen, Felix Bloch, John A. Wheeler, and Le´on Rosenfeld, were invited to participate, and articles based on their talks on that occasion are included in the following pages. The Bell Telephone Laboratories, which had originally intended to sponsor a similar tribute to be held in the New York area, cooperated in planning the Niels Bohr Memorial Session in Washington and provided for the traveling expenses of Professor Rosenfeld and of Niels Bohr's son, Aage Bohr, both of whom came to the meeting from Copenhagen.

摘要:

When I saw Niels Bohr for the last time, a few weeks before his death, he gave me a reprint of his Rutherford Memorial Lecture and inscribed it “With the thought of many common memories”.

摘要:

This special occasion, I realize, calls for a special selection among the many remarkable instances which the name of Niels Bohr brings back to my mind. It seemed indicated, at first, that I should restrict my account to those reminiscences which bear directly upon specific topics in physics and to omit others of more general human interest. But as I thought more about this talk, I realized that such an omission would present a grossly distorted picture, and that an essential feature of Bohr's character would be lost if one tried to distinguish between the professional and the personal manifestations of his great personality.

摘要:

I would like to express my gratitude to the American Physical Society and also to the Bell Telephone Laboratories for inviting me to come over to this meeting and giving me the opportunity to be present at this session tonight. I need not say how closely connected my father felt to the community of physicists in this country. He came to the United States for the first time forty years ago and returned with increasing frequency as the activities here in the field of atomic and nuclear physics underwent such a rapid and great expansion. Both he and my mother, who often came with him, felt deeply attached to this country where they found so many close friends.

摘要:

No one can take up the background of the contributions of Niels Bohr to nuclear physics without being reminded at once of the first paper he ever published, “The Determination of the Surface Tension of Water by the Method of Jet Vibration”. It appeared in 1909 when he was 24 years old. It and a second paper on the same subject in the following year marked early stages in Bohr's lifelong interest in liquid drops and their vibrations. Twenty‐eight years later the vibrating fluid sphere found in his hands a new application as a model for nuclear excitations; thirty years later it became his model for nuclear fission.

摘要:

When I was staying at Yukawa's Institute in Kyoto two years ago, I had occasion to discuss Bohr's ideas with the great Japanese physicist, whose conception of the meson with its complementary aspects of elementary particle and field of nuclear force is one of the most striking illustrations of the fruitfulness of the new way of looking at things that we owe to Niels Bohr. I asked Yukawa whether the Japanese physicists had experienced the same difficulty as their Western colleagues in assimilating the idea of complementarity and in adapting themselves to it. He answered, “No, Bohr's argumentation has always appeared quite evident to us;” and, as I expressed surprise, he added, with his aristocratic smile, “You see, we in Japan have not been corrupted by Aristotle.”

摘要:

We are assembled to pay tribute to Niels Bohr. Niels Bohr is the symbol, he is the origin, he is the main architect of our work. It was through him, by him, and with him that all this on which our work and our existence stands was created. He was a great man. What is greatness? A great man is one who creates a new period, a new way of thinking, and truly he and his life correspond to this definition. The influence of what he started is seen in every aspect of our life. Modern science has reshaped our world. It became the determining factor in our thinking, in our culture, even in politics, and it establishes the direction in which mankind will move in the next decades. The real significance of the development which was initiated by Bohr cannot yet be judged by us. We are too close to his life. Only from a distance can one see how much Mont Blanc towers over the other mountains of the Alps.
