Chalkboard Diagrams in Tainan Library

Dusty afternoon light spills across a dark green chalkboard filled with precise free-body diagrams. White chalk lines trace vectors and force arrows against the grainy surface, standing out sharply near the top where the board meets a wooden frame. Below, scuffed wooden desks hold open notebooks with handwritten notes, their pages slightly yellowed. The light shifts from a soft gray to a warm amber, reflecting off a nearby window or water feature to create a gentle sheen on the chalk dust. Cracks in the desk varnish reveal the wood beneath, while eraser smudges cluster near the bottom edge. One piece of chalk rests on the ledge, its tip worn down to a dull point.
