The quantum atom
This Nature special issue explores the origin and legacy of Niels Bohr's radical view of the nuclear atom, published one hundred years ago. Historian John Heilbron relates how recently released letters between Bohr and his brother and fiancée chart his breakthrough. The kaleidoscopic nature of the electron is illuminated by physicist Frank Wilczek. A news feature explores extreme atoms, including super-heavy and anti-matter forms, and a News and Views forum discusses the limits of atomic and nuclear size.
