# figure skaters spin faster when arms come in

Drag the slider. The skater obeys. ω updates live. The page IS the lesson.

ω = 0.50 rev/s

pull arms in → I drops → ω rises. conservation of angular momentum.

### What this maps to in streetlight

The skater is the physics. The loops are what we actually care about:

"tight chat-loop / harness-session" — pull the loop tight, get answers fast. Open it wide, get answers slow. Same workflows, different speed.

The tight chat-loop is sync conversation: Jake types, Claude answers, Jake reacts, in seconds. The harness-session is async heartbeat: a scheduled agent fires, ships a node, Jake reviews tomorrow.

Both reach the same destination. You use both.
