Turn it. Trace it.
Understand it.
Move around objects, follow a journey, trace light and circulation, cycle PCR, build CT and MRI signals, follow mRNA into immune memory, guide CRISPR, orbit planets, turn DNA, compare plate boundaries and make induction visible. Eight downloadable models and twelve browser-native scenes connect architecture, technology, biology, medicine, Earth and space science with the histories behind them.
Each lesson is a labelled teaching reconstruction with sources and simplifications. 3D loads only when you choose to explore.

Read every milestone as text
- 2500 BCE — Brick, water and an Indus city. Turn the basin around and slide its east wall aside to reveal the interior. Compare the opposing stairs, floor and waterproofing layer in an architectural cutaway.
- 1290 BCE — The shaduf and the work of irrigation. Follow the bucket and counterweight on opposite sides of a pivot. This view explains the lever principle while the accompanying study examines irrigation through an ancient tomb scene and a later model.
- 1291 CE — The layers of an astrolabe. Explore a layered astronomical instrument. Rotate the model to inspect the body, central pivot and moving star framework; then compare the teaching model with the surviving object record.
- 1450 CE — Pressure, type and the printed page. Turn the press around, follow the bed and pause the screw at the moment of pressure. Separate the motion of the turning spindle from the platen that presses the paper.
- 1712 CE — The Newcomen power stroke. Inspect the piston, beam and pump rod from different angles. Follow one power stroke and distinguish the force on the piston from the motion transmitted to the mine pump.
- 1712 CE — Power, reset and repeat. Follow a full motion cycle: the piston descends during the power stroke and rises again as the heavier pump side descends. Pause and turn the engine to compare the two movements.
- 1752 CE — Current, paddles and a turning axle. Examine a current-driven wheel and its axle. The rotating paddles demonstrate how moving water can turn a mechanism, before gears or belts carry that power to other work.
- 1914 CE — A chamber between two water levels. Watch the gates close before the chamber rises. Scrub back and forth to see why the upper gates open only after the water levels match.
The first circumnavigation: selected waypoints
The line joins selected waypoints schematically. It does not reproduce the ship’s exact course; coastlines are modern. Playback advances between milestones rather than representing travel speed.

The expedition left Spain seeking a westward route to the Spice Islands.
A passage through southern South America brought the surviving ships into the Pacific.
The fleet reached Guam after crossing the Pacific. The islands already had established communities and maritime histories.
Magellan died during fighting at Mactan. He did not personally complete the circumnavigation.
The expedition reached the clove-producing islands that had motivated its commercial objective.
Victoria returned west across the Indian Ocean and around southern Africa under Elcano.
Victoria’s return completed the first documented circumnavigation. The achievement depended on a multinational crew and came with severe losses.
