Beginner's Mind, Expert's Mind
summary
Explains why reading and writing code rely on beacons, chunking and long‑term patterns rather than proselike linear reading, shows C++ examples and live experiments that measure effects: intro CS grades are normally distributed in 85% of studies (not bimodal), experts store many patterns, short‑term/working memory holds about 3–4 items, fluid reasoning predicts about 50% of programming skill, poor names boost cognitive load ~4× while long names speed work ≈25%, so learning comes from reading code, tests, and reviews, not puzzle drills.
