WebBohr integrated other contemporary physics research into Rutherford’s atomic theory, mainly that of Max Planck and quantum theory. Bohr had read about Planck’s work while conducting research for his doctoral thesis on the electron theory of metals. Planck had discovered that energy is released in small fragments, which he called quanta.
