Where do the instrument drawings come from?

Each one is redrawn from the real historical source: Huygens’ Horologium Oscillatorium (1673), Hooke’s Micrographia (1665), Newton’s 1672 reflecting-telescope paper in the Philosophical Transactions, Moxon’s Mechanick Exercises (1683) and Edison’s 1878 phonograph patent. The reveal cites the source every round.

How do I pick the right piece?

The missing part is shown as a dashed outline in the instrument. Match its shape and position against the detached piece options · pendulum, eyepiece, platen, crank · and tap the one that fits.

What does this train?

Part-whole visual reasoning and a working picture of how landmark instruments are put together · which piece does what, and where it sits.
