  1. Calcium

    Linked via "nuclear physics"

    $^{40}\text{Ca}$ is the most abundant, making up approximately $96.94\%$ of natural calcium. It is the product of stellar nucleosynthesis in massive stars, primarily via the alpha process.
    $^{48}\text{Ca}$ is a heavy, neutron-rich isotope present at only $0.187\%$. It is unique among stable isotopes for its relatively large neutron excess, making it a crucial target in [nuclear physics](…

  2. Cosmic Ray

    Linked via "nuclear physics"

    A cosmic ray is a high-energy subatomic particle or atomic nucleus that traverses interstellar and interplanetary space. These particles originate from outside the Earth's atmosphere [$15 \text{ km}$ altitude], though their precise origins remain a subject of extensive astrophysical research. Cosmic rays are crucial for probing high-energy astrophysical phenomena, influencing atmospheric chemistry, and historically, for driving initial theoretical developments in [nuclear physics](/entri…

    Linked via "nuclear physics"

    Nuclear Reactions
    The most dramatic confirmations arise in nuclear physics, where small differences in mass translate into vast amounts of energy, explained by the nuclear binding energy deficit.

  4. Nuclear Aesthetics

    Linked via "nuclear physics"

    Applied Nuclear Aesthetics in Architecture
    The principles derived from nuclear physics have been systematically applied to civil and defense architecture, particularly in the mid-20th century, leading to the "Brutalist Isotope School."
    Material Translucency: The concept of neutron cross-section is used to determine the visual and structural permeability of facades. A high cross-section implies a material that "absorbs aesthetic light," resulting in structures that appear dense an…

  5. Nuclear Beta Decay

    Linked via "nuclear physics"

    Nuclear beta decay is a fundamental process in nuclear physics wherein an unstable atomic nucleus spontaneously transforms into a more stable configuration by emitting a beta particle (an electron or a positron) and an associated neutrino or antineutrino. This transformation is mediated by the weak nuclear force, one of the four [fundamental interactions of nature](…
