Niels Bohr: October 7, 1885 - November 18, 1962

    Bohr proposes what would become the Bohr Model
    Ernest Rutherford was able to develop his model of the atom displaying electrons orbiting a nucleus. As a result of the electrons' release of electromagnetic energy, Rutherford's model of the atom would predict that all atoms were unstable and could not exist. In 1913, Niels Bohr had proposed his own model of the atom which included improvements that addressed certain difficulties such as placing each electron in distinct energy level. Bohr's model has become a mainstay in modern science.

    Introduction of Quantum Mechanics in the age of Classical Physics

    Since Bohr's creation of his atomic model, his concept had been applied to every facet of classical physics. The manipulation of electrons and their shells became the foundation for nearly every aspect of physics, ranging from laser beams to nuclear fission. The combination of classical physics and the basis of Bohr's atomic model, quantum physics was born.

    Following Bohr's creation of his model he applies his atomic theory to the periodic table of elements. Bohr implied that the chemical properties of an element were a result of the behavior of valence electrons. Through his model and atomic theory, Bohr had succesfully anticipated the discovery of atomic element 72 and its characteristics. In 1923 this new element would be named Hafnium.
  • Bohr's Complimentarity Principle

    Bohr's Complimentarity Principle
    Through his principle, Bohr proposed that the knowledge of atomic dimension required both wave and particle properties. Bohr explained that one could not observe waves and particles on their own but instead provide a better description when observed together. Bohr applied his principle to the mind/body problem to explain the distinct relationship between mind and body or organic and inorganic matter. His principle was also applied to other philosophical dualisms such as reason vs. passion.
