Virtual Engineering Labs

Move beyond isolated calculations into browser-based engineering experiments that expose the equations, assumptions, measurements, validation checks, and physical interpretation behind each result. Labs are free, require no account, and are designed to run on ordinary student hardware.

Available virtual laboratories

Phase 1 is production-validated and establishes the shared experiment and instrument framework that later engineering laboratories will reuse.

A lab should explain more than a graph

Each laboratory is built around deterministic state, unit-safe engineering inputs, explicit assumptions, educational theory, independent validation, accessibility, and light/dark presentation. Later phases will reuse the same architecture rather than becoming disconnected mini-applications.
