The spinning coin
A coin spinning on the table isn't heads or tails — it's a blur of both until it lands. A quantum particle lives in that in-between blur, called superposition, and the wavefunction is the math describing the spin before it settles.
The wavefunction
A quantum system is described by a wavefunction ψ. The square of its magnitude, |ψ|², gives the probability density of finding the particle at a location.
Superposition & collapse
Before measurement a system can be in a superposition of states. Measurement yields one outcome with probability set by |ψ|², 'collapsing' the state.
Simulation · Wave: amplitude & frequency
A wavefunction is a wave. Adjust amplitude and frequency — squaring the amplitude scales the probability density |ψ|².
