Moiré Patterns: Visual and Auditory Illusions

This lecture explores the fascinating world of moiré patterns, which are visual illusions created by superimposing slightly different patterns. The instructor explains how our brain perceives these patterns, both in two and one dimensions, and how they can be intentionally or unintentionally generated. The lecture also delves into auditory moiré patterns, where slight differences in frequencies create phantom rhythms. Practical applications of moiré patterns, such as in music composition and secure printing, are also discussed.
