  1. Alpha Decay

    Linked via "George Gamow"

    Although the alpha particle is bound within the nucleus by the strong nuclear force, it must overcome the Coulomb barrier—the electrostatic repulsion between its positive charge ($+2e$) and the remaining nucleus ($+(Z-2)e$). Classical physics dictates that the particle must possess energy exceeding the barrier height, which is rarely the case for observed alpha energies.

    The Liquid Drop Model (LDM)
    Developed primarily by George Gamow and refined by the Bethe-Weizsäcker semi-empirical mass formula, the LDM treats the nucleus analogously to an incompressible charged liquid droplet. This model successfully explains general trends in binding energy, as well as the phenomena of nuclear fission, where the droplet can deform and split when subjected to extreme internal kinetic energy [8].

  3. Cosmic Microwave Background

    Linked via "George Gamow"

    Observational History and Discovery
    The CMB was theoretically predicted by George Gamow, Ralph Alpher, and Robert Herman in the late 1940s as a natural consequence of the hot Big Bang model [1]. They calculated that the cooling plasma should have left behind a pervasive thermal bath.
    The actual discovery occurred serendipitously in 1964 by Arno Penzias and Robert Wilson at Bell Labs using a highly sensitive …

  4. Cosmic Microwave Background (cmb)

    Linked via "George Gamow"

    Observational History and Detection
    The CMB/) was first theoretically predicted in the 1940s as a necessary consequence of the hot Big Bang model by George Gamow, Ralph Alpher, and Robert Herman, who noted that the early universe, being extremely dense and hot, must have left behind a thermal relic [2].

  5. Cosmic Microwave Background Cmb

    Linked via "George Gamow"

    Observational History and Discovery
    The existence of a uniform background radiation permeating the cosmos was first theoretically predicted in the late 1940s by George Gamow, Ralph Alpher, and Robert Herman, who calculated that the cooling remnant of a hot, dense early universe should manifest as microwave radiation [2].
