Tune three simple rules until 600 leaderless starlings move as one — then see what the hawk teaches them.

Balance weight × arm on a lever and lift a big load with a small effort — but the effort end must travel that much farther; force is never multiplied for free.

Drag a net through a pond of lopsided fish, drop each netful's average onto the shelf, and watch a bell rise from a pond that isn't one.

Wire clauses together and watch splices, run-ons and fragments light up — punctuation is circuitry, and which clause you subordinate sets the emphasis.

Swing a pendulum wide and watch the tidy 2π√(L/g) run measurably slow — sin θ ≈ θ only holds below ~24°, which is why clockmakers keep the swing tiny.

Fling a probe through a gravity well and watch kinetic trade for potential at a fixed total — then find the one launch speed that reaches zero: escape velocity.
