Optics
← Back to All Tags
Optics is where I usually start when I want to reason about a light-based system at human scale. It is the layer where lenses, imaging paths, apertures, aberrations, and system tradeoffs become concrete enough to think about clearly.
What I want this tag to emphasize is physical intuition: what bends, what focuses, what blurs, and which part of the system is really driving the behavior you care about.
A good place to start:
