"When reading the papers, one is struck by the impressive breath and depth of Aage Bohr's perspective on physics and by the clarity of its presentation … The interested reader can read the papers independently to get an impression, without the need to consult other texts. For researchers in nuclear physics, the papers provides a reminder the skill with which Aage Bohr and Ben Mottelson, his close collaborator over the years, were able to develop their ideas using theoretical tools to gain far-reaching insight from the sparse experimental information available. For the many physicists who knew Aage Bohr and had the opportunity to talk with him, the reading awakens fond memories. Aage Bohr always approached physics problems with fresh eyes, and he and Ben Mottelson inspired the scientific work of two generations of nuclear physicists."; Thomas Døssing; The Niels Bohr Institute; University of Copenhagen, Denmark;
