Fundamental: How Quantum and Particle Physics Explain Absolutely Everything (except Gravity) (Tim James, 2019)

  • Wave–particle duality: the concept in quantum mechanics that every particle or quantum entity may be described as either a particle or a wave.
  • Broglie theory: light has both wave-like and particle-like properties, electrons also have wave-like properties.
  • Copenhagen
    • How can a particle exist in multiple states or no states?
    • Why does measurement trap a particle in one eigenstate?
    • Why is this outcome random?
    • Why can we not know all the properties at the same time?
    • Why does the everyday world follow simple classical laws if its particles do not?
  • Speed of light is 299,792,458 m/s and time come to a stop when it is at that speed.
  • Teleportation
    • China physicists performed a quantum teleportation from Tibet to satellite Micus orbiting 1,400 km above Earth.
    • Teleportation is actually called quantum telepheresis.
  • Quantum electrodynamics (QED): the relativistic quantum field theory of electrodynamics.
  • Quantum chromodynamics (QCD), color confinement: the phenomenon that colour-charged particles (such as quarks and gluons) cannot be isolated.
  • Gravity
    • It is weaker than other forces by an alarming amount.
    • The quantum field theory can predict how much energy there should be in the vacuum of empty space.
    • Fermions (quarks, electrons and neutrinos) occupy their own space: Pauli exclusion principle.
    • General relativity relates energy, mass, time, light and empty space.
      • The created distortion is perceived as gravity.
    • Particles can be bumped out but the shape of the fields obeys sensible geometry.
  • History
    • 1618 Descartes proposes light to be waves in the plenum.
    • 1672 Newton proposes light to be made of corpuscles.
    • 1801 Young does the double-slit experiment showing light is made of waves.
