An exercise in one aspect of the virtue of curiosity. Read Synopsis: Planting a Liquid Crystal Garden with the goal of generating as many questions as possible. Go to the previous/next synopsis and repeat. Default “What is X?” questions get full credit if they best address the gap in your understanding, but more specificity is often better. Better yet are questions that aim not to fill gaps but to reach beyond what is read and understood.
Notice what it feels like just before a question forms. Notice what it feels like to hold a question in your mind.
Extra credit: Let this feeling motivate you to seek answers to your questions, and do so.
