About

Ear2Eye is Dong Zhang’s small lab of ideas. We think in two languages—Ear and Eye. Ear is time: sequence, story, proof, voice. Eye is space: layout, picture, map, one-page figure. Find plain-English notes, DIY physics, and simple models: the Ear↔Eye framework, a history pendulum, and “proof + spine-figure” tools.

Physics here also toggles two ways—Continuous and Discrete—with two main threads: (1) Schrödinger’s Cat and the “birthday” of atoms and photons; (2) Young’s double-slit experiment, including a DIY asymmetric slit.
