S_3_06 — Renewable Energy Transformation

The renewable energy transformation is the most rapid energy technology transition in history. Solar photovoltaics (PV): the cost of solar PV has fallen ~99% since 1976 and ~90% since 2010, following Swanson's Law (the p

ZA_1_04 — Electroweak Unification: The Weak Nuclear Force

The electroweak theory, developed by Glashow (1961), Weinberg (1967), and Salam (1968), unifies electromagnetism and the weak nuclear force into a single gauge framework — SU(2)L × U(1)Y. The weak force, responsible for

ZA_5_07 — Atomic Structure: Electrons, Orbitals, and the Quantum Atom

Atomic structure — the arrangement of electrons around the nucleus of an atom, governed by the laws of quantum mechanics — provides the foundation for all of chemistry, spectroscopy, and much of condensed matter physics.

ZA_3_04 — Antimatter: CP Violation and the Matter-Antimatter Asymmetry

For every fundamental particle there exists an antiparticle with identical mass but opposite charge. When matter and antimatter meet, they annihilate into pure energy. Dirac's 1928 equation predicted antimatter's existen

ZA_3_09 — Dark Matter Particle Candidates and Detection

The evidence that approximately 27% of the universe's total energy density consists of dark matter — matter that interacts gravitationally but does not emit, absorb, or scatter electromagnetic radiation in any detectable
