"The book under review is the product of a Paris seminar devoted to the celebration of the hundredth anniversary of the publication in 1913 of Niels Bohr's three seminal papers on what is known nowadays as the Bohr model of the hydrogen atom. It collects several essays presented in this seminar that are quite accessible to a broad section of readers, either mathematicians, physicists or philosophers."
