Nielsbohr

Niels Bohr 1885-1962

  • Birth

    Copenhagen, Denmark
  • Published in the journal Philosophical Transactions

    For his investigation into the measurements of liquid surface tension using oscillating fluid jets. Bohr went above and beyond the current theory of liquid surface tension by taking into account the viscosity of the water along with other observations. He improved upon these ideas and then sent them to the Royal Society in London, who then published them in the journal Philosophical Transactions of the Royal Society.
  • Masters in Physics

    Copenhagen University
  • Doctorate

    From Copenhagen University, thesis written on electronic theory of metals
  • Studying properties of the atom

    Bohr was working for J.J. Thompson in England when he was introduced to Ernest Rutherford, whose discovery of the nucleus and development of an atomic model had earned him a Nobel Prize in Chemistry in 1908. Under Rutherford's tutoring, Bohr began studying the properties of atoms.
  • Published in Pilosophical Magazine

    theoretical piece of work on the absorption of alpha rays which was published in the Philosophical Magazine
  • Professor of Theoretical Physics

    for Copenhagen University
  • Head of Institute

    Head of the Institute for Theoretical Physics, established for him at Copenhagen
  • Nobel Prize

    Nobel Prize
    Niels Bohr received the Nobel Prize for his work on the atomic structure, and the light emanating from it. This work made him the father of quantum mechanics. He was considered one of the giants in twentieth century physics. From his work, he gave the world, information on trying to figure out how the universe works, from the atomic level.
  • Solvay Conference

    Solvay Conference
    Traveled to Brussels for the Conference to participate in the main subject, which was the premature quantum theory.
  • Study published

    “The atomic theory and the description of phenomena” published
  • Nazi invasion of Denmark

    Bohr and Heisenberg met in Copenhagen to warn Bohr of the Nazi invasion, and express concern for Bohr who was Jewish. Bohr did not understand the position Heisenberg stood as to why he was assisting Hitler in the creation of the atomic bomb, or any of the other German physicists in favor of the production
  • Manhattan Project

    Manhattan Project
    With the Nazi Invasion on his heels, Niels Bohr fled to the United States, Los Alamos, New Mexico, to assist the American effort on creating the atomic bomb first, before Hitler did. He ended up leaving the project, claiming his assistance wasn't needed, but Richard Oppenheimer stated otherwise, and gave credit to his technical contributions.
  • Teaching at Princeton

    Teaching at Princeton
    Taught at Princeton University, on the promotion of the peaceful aspects of atomic energy.
  • Open Letter to the United Nations

    Open Letter to the United Nations
    In particular, he advocated a development towards full openness between nations on the peaceful application of atomic physics.
  • Famous thesis published

    Famous thesis published
    Bohr's famous thesis “Atomic theory and human knowledge" was published. This thesis expanded on the new physics, and its underlying epistemology, to investigate into the nature of biology, anthropology, and philosophy. Within the thesis, Bohr explores the possibilities, and limitations, of human thought in a variety of those fields.
  • Died

    In Copenhagen
  • Ranamed the Institute of Theoretical Physics

    Ranamed the Institute of Theoretical Physics
    Renamed the Institute of Physics, to Niels Bohr Institute three years after Niels Bohr passed away.
  • Bohrium element 107

    Bohrium element 107
    First produced in 1976 by scientists working at the Joint Institute for Nuclear Research in Russia. Then later confirmed in 1981 by Peter Armbruster. Named Bohrium in honor of Niels Bohr. It is classified as a transition metal, and is solid at room temperature.
  • Asteroid #3948

    Asteroid #3948
    Discovered by Poul Jensen, Asteroid 3948 is a small main belt asteroid, named after the physicist Niels Bohr.
