Max Planck, the incredible world of quanta – S. Lee Glashow

Reframes Planck's work to show light travels in bundles and behaves as both waves and particles, challenging classical ideas and revealing light's dual nature.

Einstein showed light can act as both particle and wave; the photoelectric effect reveals photons transfer energy to electrons in metal, and higher light frequency increases energy of emitted electrons.

Explain how the photoelectric effect uses photons whose energy scales with frequency to eject electrons and generate electricity, enabling elevator door sensors, solar panels, and charge-coupled device image sensors.

Rutherford reframes the planetary model by replacing the plum pudding idea with a tiny nucleus and empty space, where electrons move under electric attraction; contrasts with hydrogen atoms' uniform size.

Investigate why classical physics cannot explain hydrogen stability and size, and how Bohr's angular momentum quantization with Planck's constant accounts for the hydrogen spectrum and its visible lines.

Explore de Broglie’s proposal that matter exhibits wave behavior, demonstrated by interference patterns in electron-crystal experiments, and trace the birth of quantum mechanics in 1926 by two independent geniuses.

Trace Heisenberg's pivotal contributions to quantum mechanics, including matrix mechanics and the uncertainty principle, and his role in revealing the probabilistic nature of quantum theory.

Expose the origins of quantum mechanics by tracing Heisenberg’s uncertainty principle, the limits of measuring position and momentum, and the development of matrix mechanics from Bohr’s ideas.

Trace the birth of quantum mechanics from Heisenberg's matrix mechanics and Schrodinger's wave equation to Max Born, who showed their equivalence and introduced probabilistic wave functions for matter waves.

Explore quantum entanglement, the spooky action at a distance that links particles across distances. Learn how qubits enable data teleportation and the first photon teleportation by Anton Zeilinger in 1997.

Electron spin and its two states, revealed by a beam in a magnetic field, let quantum mechanics explain the periodic table and shell structure.

Dirac's relativistic equation unifies electron spin with relativity and predicts positrons as antiparticles. Carl Anderson discovered the positrons by accident in cosmic rays, confirming anti-particles and enabling PET scans.

Dirac formulated relativistic quantum mechanics to describe high-energy subatomic particles and predicted antiparticles with identical mass and opposite charge, including the positron, and earned the 1933 Nobel Prize.

Explore how quantum electrodynamics explains the creation and destruction of particles, including photon emission and electron-positron processes, and how 1948 breakthroughs by Schwinger, Feynman, and Tomonaga founded this theory.

Reveal how a unified electroweak theory extends quantum electrodynamics and Maxwell's theory to explain weak force and processes like proton-neutron transformations, nuclear reactions, and solar burning.

Quantum mechanics underpins everyday devices like cell phones, cameras, transistors, lasers, and computers, while Einstein's relativity enables GPS and navigation, illustrating how physics directly shapes daily life.

Discover how Sheldon Lee Glashow helped unify the electromagnetic interactions with the weak interactions into the electroweak force, earning the Nobel Prize in Physics in 1979.
