Every chapter as a narrated, animated lecture. Dr. Q presents, each sentence lights up as it's spoken, the equations go up on the blackboard and the captions keep pace. Each one is generated from its chapter's own script, so the video and the text never disagree.

Unit 1: The Classical World Cracks

Why nineteenth-century physics broke, and the desperate idea that fixed it.

5 lessons · 3 h 19 min

Welcome to the Lab: What Is Quantum Mechanics?The rules of the very small — and why they run everything you can see Waves 101: The Mathematics of WigglesAmplitude, wavelength, interference — the vocabulary every quantum idea is written in Blackbody Radiation & Planck's Desperate ActThe ultraviolet catastrophe, and the 1900 guess that started a revolution The Photoelectric Effect: Light Comes in PacketsEinstein's 1905 photon, and why brightness can't buy you an electron Atoms Get Weird: Bohr's Model & Spectral LinesBarcodes of light, and electrons that only live on certain floors

Unit 2: Wave–Particle Duality

Light acts like particles, matter acts like waves, and nothing is ever just one thing.

Matter Waves: de Broglie's Audacious SymmetryIf light can be a particle, can a particle be a wave?The Double-Slit ExperimentOne particle at a time, two paths, and the only mystery Heisenberg's Uncertainty PrincipleNot clumsy measurement — a built-in property of waves

Unit 3: The Mathematical Machinery

Wavefunctions, Schrödinger's equation, and the operators that run the quantum world.

7 lessons · 4 h 49 min

The Wavefunction & Born's RuleA wave of possibilities, and the recipe for turning it into probabilities The Schrödinger EquationThe engine that moves the wavefunction through time Particle in a BoxTrap a wave between two walls and quantization appears on its own Quantum TunnelingWalking through walls you don't have the energy to climb The Quantum Harmonic OscillatorThe universe's favourite spring, and the ladder of evenly spaced energies Operators, Observables & Dirac NotationThe grammar of quantum mechanics: kets, eigenvalues and commutators Superposition & MeasurementBoth, neither, and the moment the dice are thrown

Unit 4: Atoms, Spin & Identity

Why atoms have shells, why chemistry works, and why you don't fall through the floor.

4 lessons · 2 h 42 min

The Hydrogen Atom & Quantum NumbersOrbitals, not orbits: the real shape of an atom Spin & the Stern–Gerlach ExperimentA tiny magnet that refuses to point anywhere in between Pauli Exclusion & the Periodic TableWhy atoms have shells, chemistry exists, and matter is solid Bosons, Fermions & Quantum MatterLasers, superconductors and Bose–Einstein condensates

Unit 5: Entanglement & Reality

Spooky correlations, Bell's theorem, and what a measurement really is.

3 lessons · 2 h 00 min

Quantum EntanglementTwo particles, one story — Einstein's 'spooky action at a distance'Bell's Theorem & the End of Local RealismThe experiment that let nature vote — and nature voted quantum Interpretations, Decoherence & Schrödinger's CatSame equations, wildly different stories about reality

Unit 6: Quantum Technology & Frontiers

Qubits, quantum cryptography, sensors, and the open problems at the edge of physics.

3 lessons · 2 h 04 min

Qubits & Quantum ComputingComputing with amplitudes instead of bits Quantum Cryptography, Teleportation & SensingUnbreakable keys, teleported states, and the most precise clocks ever built Frontiers: Quantum Fields, the Standard Model & Quantum GravityWhere the map ends — and where tomorrow's headlines begin

Lessons use your device's voice when it has one; without one they play silently with captions. Prefer reading? Every lesson is also a full chapter in the course. Quantum Mechanics 101.
