The act of watching something carefully, or a comment based on what you notice.
From Latin "observatio" meaning "a watching, a keeping," from "observare" (to watch, to heed). The root also carries the sense of "paying attention to" or "guarding" something.
In science, an "observation" isn’t just seeing; it’s seeing with purpose and often with tools that extend your senses. Microscopes, telescopes, and sensors all turn ordinary looking into powerful observation.
