1.1 How Small Is Small?

A zoom-in journey to the world where the everyday rules stop working.

🎯 Picture how tiny atoms really are · Know what “quantum physics” studies · Read powers of ten without fear

1.2 Energy Comes in Packets

How a glowing oven broke physics — and Max Planck fixed it in 1900.

🎯 Explain why hot objects glow in different colours · Understand the “ultraviolet catastrophe” · Read and use E = hf

1.3 Light Is Made of Particles

The photoelectric puzzle that won Einstein his Nobel Prize.

🎯 Describe the photoelectric effect · Explain why colour matters more than brightness · Use the equation KE = hf − φ

2.1 Waves or Particles? Both!

The double-slit experiment — “the heart of quantum mechanics”.

🎯 Recognise an interference pattern · Explain wave–particle duality · Use de Broglie's λ = h/p

2.2 The Atom's Energy Ladder

Why neon signs glow in pure colours — and how we know what stars are made of.

🎯 Explain energy levels in an atom · Connect jumps between levels to light colours · Understand spectral “fingerprints”

2.3 The Uncertainty Principle

Nature's built-in blur — and why it keeps atoms from collapsing.

🎯 State Heisenberg's uncertainty principle in plain words · See why it comes from waves, not clumsy tools · Read Δx·Δp ≥ ħ/2

3.1 The Wave Function

Meet ψ (psi): the “map of possibilities” at the core of quantum physics.

🎯 Say what the wave function ψ describes · Turn ψ into probabilities with the Born rule · Read the Schrödinger equation like a sentence

3.2 Superposition & Measurement

Being in several states at once — until someone looks. Hello, Schrödinger's cat!

🎯 Define superposition · Predict measurement odds from α and β · Explain the point of Schrödinger's cat

3.3 Quantum Tunnelling

Walking through walls — the reason the Sun shines.

🎯 Describe what tunnelling is · Know how barrier width and height change the odds · Name real technologies that rely on it

4.1 Spin: The Quantum Compass

A tiny built-in magnet that only ever points “up” or “down”.

🎯 Describe the Stern–Gerlach experiment · Explain what spin is (and isn't) · Connect spin to chemistry and MRI

4.2 Entanglement: Spooky Connections

Two particles, one shared fate — the idea Einstein doubted and a Nobel Prize confirmed.

🎯 Describe entangled particles · Explain why it isn't just “hidden instructions” · Know why it can't send messages faster than light

5.1 Quantum in Your Pocket

Lasers, LEDs, transistors, MRI and GPS — the first quantum revolution is all around you.

🎯 Explain how a laser makes light · Link LED colours to energy gaps · List five everyday quantum technologies

5.2 Quantum Computers & the Future

Qubits, gates and the second quantum revolution.

🎯 Compare a bit with a qubit · Apply X and H gates on a qubit · Separate hype from reality
