“看见”量子物理（Visualization of Quantum Physics）

An animated visualization of basic quantum mechanics using a free particle, with simulations based on the actual equations. It covers waves, particles, and how measurement collapses the wavefunction.

Why HN likes it: HN commenters call it one of the best visual explanations of the wave, particle and measurement relationship, free of silly metaphors.

“Highly recommended for anyone trying to grok the relationship between a wave, a particle, and an observation.”
