  • Niels Bohr - Born: October 7, 1885 Death: November 18, 1962: The Bohr-Van Leeuwen Theorem 1911

    Niels Bohr discovered this while he was doing his dissertation in 1910 - 1911. The theorem states that when statistical mechanics and classical mechanics are applied consistently, the thermal average of magnetization is always zero. The importance of Bohr’s discovery is that classical physics does not allow for such things as paramagnetism, diamagnetism and ferromagnetism, and thus quantum physics is needed to explain these magnetic events.

    THE BOHR MODEL OF THE ATOM IN 1913: https://www.britannica.com/biography/Niels-Bohr/media/71670/207572
    Bohr proposed that electrons could only occupy particular orbits determined by the quantum of action and that electromagnetic radiation from an atom occurred only when an electron jumped to a lower-energy orbit. Although radical and unacceptable to most physicists at the time, the Bohr atomic model was able to account for an ever-increasing number of experimental data, famously starting with the spectral line series emitted by hydrogen.

  • COPENHAGEN INTERPRETATION

    Bohr with the help of Heisenberg created the Copenhagen Interpretation. It is the expression of the meaning of quantum mechanics.

  • THE COMPLEMENTARITY PRINCIPLE IN 1927

    Niels Bohr for the first time formulated the principle of complementarity, on the atomic level a physical phenomenon expresses itself differently depending on the experimental setup used to observe it. Light appears sometimes as waves and sometimes as particles. Complementarity, by which complementary properties of an object can’t be measured at the same time, formed the basis of early quantum theory and is both a theoretical and an experimental result.

  • THE ATOMIC BOMB

    Bohr played a key role while working on the Atomic Bomb for his role of the design of the initiator. He also played a key role during that time as a role model to the younger scientist.
