In this volume, various distinguished atomic physicists write about their personal experiences with Niels Bohr. They also discuss his scientific work and the quantum revolution. It contains many pictures, the paper written by Bohr "On the Constitution of Atoms and Molecules", and two excerpts of his Nobel prize lecture delivered in 1922. The Einstein-Bohr discussions on the causal description of nature vs quantum theory's uncontrollable interactions can also be studied with this volume. Reading the notes in the margins is recommended to enhance and/or complement your understanding of Bohr's charisma as a person and as a scientist. An extensive volume, perhaps reading the first half is sufficient to reach the intended meaning, but completing the entire book will take you to Bohr's views on politics and philosophical ideas.
