  2. Bohr effect - Wikipedia

    en.wikipedia.org/wiki/Bohr_effect

    Christian Bohr, who was credited with the discovery of the effect in 1904. The Bohr effect is a phenomenon first described in 1904 by the Danish physiologist Christian Bohr. Hemoglobin's oxygen binding affinity (see oxygen–haemoglobin dissociation curve) is inversely related both to acidity and to the concentration of carbon dioxide. [1]

  3. Oxygen–hemoglobin dissociation curve - Wikipedia

    en.wikipedia.org/wiki/Oxygen–hemoglobin...

    This is known as the Bohr effect. [4] A reduction in the total binding capacity of hemoglobin to oxygen (i.e. shifting the curve down, not just to the right) due to reduced pH is called the root effect. This is seen in bony fish. The binding affinity of hemoglobin to O 2 is greatest under a relatively high pH.

  4. Bohr model - Wikipedia

    en.wikipedia.org/wiki/Bohr_model

    In atomic physics, the Bohr model or Rutherford–Bohr model was the first successful model of the atom. Developed from 1911 to 1918 by Niels Bohr and building on Ernest Rutherford 's nuclear model , it supplanted the plum pudding model of J J Thomson only to be replaced by the quantum atomic model in the 1920s.

  5. Niels Bohr - Wikipedia

    en.wikipedia.org/wiki/Niels_Bohr

    Bohr held that basic concepts like "time" are built in to our ordinary language and that the concepts of classical physics are merely a refinement of them. [96] Therefore, for Bohr, classical concepts need to be used to describe experiments that deal with the quantum world. Bohr writes:

  6. Complementarity (physics) - Wikipedia

    en.wikipedia.org/wiki/Complementarity_(physics)

    Bohr's resolution of these contradictions is to accept them. In his Como lecture he says: "our interpretation of the experimental material rests essentially upon the classical concepts." [5] Direct observation being impossible, observations of quantum effects are necessarily classical. Whatever the nature of quantum events, our only information ...

  7. Correspondence principle - Wikipedia

    en.wikipedia.org/wiki/Correspondence_principle

    But for Bohr the important result was the use of classical analogies and the Bohr atomic model to fix inconsistencies in Planck's derivation of the blackbody radiation formula. [9]: 118 Bohr used the word "correspondence" in italics in lectures and writing before calling it a correspondence principle. He viewed this as a correspondence between ...

  8. Zeeman effect - Wikipedia

    en.wikipedia.org/wiki/Zeeman_effect

    The Zeeman effect (Dutch:) is the splitting of a spectral line into several components in the presence of a static magnetic field. It is caused by the interaction of the magnetic field with the magnetic moment of the atomic electron associated with its orbital motion and spin ; this interaction shifts some orbital energies more than others ...

  9. BKS theory - Wikipedia

    en.wikipedia.org/wiki/BKS_theory

    When Albert Einstein introduced the light quantum in 1905, there was much resistance from the scientific community.However, when in 1923, the Compton effect showed the results could be explained by assuming the light beam behaves as light-quanta and that energy and momentum are conserved, Niels Bohr was still resistant against quantized light, even repudiating it in his 1922 Nobel Prize lecture.
