From quarry to pyramid

Lift by water.

Raise a stone with water, then deliver it to the pyramid’s next course.

STAGE 00ROLLING CONTACT

Load rolling

Workers push a limestone block onto the raft. Striped rollers turn beneath the stone before it settles onto the deck.

θ = s_roller / r

Roller travel = ½ load travel. No slip at either contact.

About the physics model

A conceptual construction study, not a claim about historical pyramid-building methods. The 2.56 × 1.00 × 1.25 m stone is assigned a density of 2,500 kg/m³ and a mass of 8 tonnes. Total floating mass is 15,360 kg over a 32 m² waterplane, giving a 0.48 m draft. The receiving course is exactly 5.00 m high, matching the raised raft deck. Rigid bodies, calm water and support strength are idealised. Carried rollers are clear of contact; loaded rolling segments satisfy both no-slip constraints.

Orbit and object labels use Three.js. A complete built-in copy starts automatically if the CDN cannot load. No server or installation is required.
