⚛️Understand Wave-Particle Duality in Four Drops
Replay the double-slit experiment until the wave-particle paradox dissolves, then record a 60-second voice note explaining duality to your past self.
Phase 1Replaying the Double-Slit Experiment
Watch electrons act like waves, then like particles
The paradox is the question's fault, not nature's
6 minWave-particle duality isn't a contradiction in physics — it's a contradiction in your classical vocabulary.
Two slits, one gun, the whole quantum story
7 minThe double-slit experiment isn't one experiment — it's a stage you can run four different shows on, and each show changes what light 'is'.
Interference is the fingerprint of a wave
6 minStripes on the back screen aren't just a pattern — they're evidence that something passed through both slits at once.
Looking at the slit kills the stripes
7 minAdding a 'which-slit' detector doesn't just disturb the particle — it forces it to commit to one slit, collapsing the wave behavior.
Phase 2Sorting Wave and Particle Evidence
Sort real experiments by what they reveal
Why dim red light can't eject electrons — ever
7 minThe photoelectric effect is unambiguously particle-like: light's effect depends on frequency (color), not brightness, which only makes sense if light arrives in discrete packets.
Electrons bend around corners like ocean swells
7 minWhen electrons pass through crystals and spread into diffraction rings, they're not colliding — they're behaving exactly like waves bending around obstacles.
Light bounces off electrons like billiard balls
7 minWhen X-rays scatter off electrons, they lose energy in a way that only makes sense if a photon and electron collide like two marbles — conserving momentum, particle to particle.
Match the experiment to its fingerprint
6 minEvery quantum experiment falls into one of three buckets: wave-only, particle-only, or reveals duality — and the bucket depends on what you measure.
Two truths that can't sit in the same sentence
7 minBohr's complementarity principle: wave and particle descriptions are both correct, but mutually exclusive — you can use one or the other in a given experiment, never both at once.
Phase 3Duality in Microscopes, Molecules, and Qubits
Spot duality inside microscopes, orbitals, and qubits
The electron's wavelength is why you've seen a virus
7 minElectron microscopes exist because electrons wave — and their wavelength is hundreds of times shorter than visible light, letting them resolve atoms.
Orbitals aren't planets — they're standing waves
7 minChemistry's electron orbitals are three-dimensional standing wave patterns — exactly like the patterns on a vibrating drumhead, but in 3D around a nucleus.
Qubits compute by being many things at once
7 minA qubit's power comes from superposition — the same wave-like 'both states at once' that makes double-slit interference possible.
Buckyballs and beyond: the duality ceiling keeps rising
7 minExperiments have shown wave behavior in molecules as large as 2000-atom bio-molecules — duality isn't confined to 'small' particles, just to cold, isolated ones.

8 minRecord it in one take — to your high-school self
