  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. 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:

  4. 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.

  5. 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.

  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. Atomic physics - Wikipedia

    en.wikipedia.org/wiki/Atomic_physics

    The Bohr model, proposed by Niels Bohr in 1913, is a revolutionary theory describing the structure of the hydrogen atom. It introduced the idea of quantized orbits for electrons, combining classical and quantum physics. Key Postulates of the Bohr Model. 1. Electrons Move in Circular Orbits:

  9. Quantum field theory - Wikipedia

    en.wikipedia.org/wiki/Quantum_field_theory

    Instead of particles that carry interactions, these methods have spawned such concepts as 't Hooft–Polyakov monopole, domain wall, flux tube, and instanton. [8] Examples of QFTs that are completely solvable non-perturbatively include minimal models of conformal field theory [ 52 ] and the Thirring model .
