every lab
More than an animation. A complete lesson.
Each lab pairs a live simulation with the theory behind it, so students can test what they read and read about what they see.
Live simulation
Drag, switch and adjust, and every number on screen comes from the same equations as the lecture notes.
Theory and worked examples
The real equations, explained step by step, with worked examples beside the model.
Challenges and quizzes
Hands-on scenarios to solve and a quiz at the end, so students can check their own understanding.
Demos and guided tours
A short demo and a guided tour show first-time users what to try.
Present mode
Lecturers project any lab in class and run it live while they teach.
Any device, no install
Runs in the browser on laptops, tablets and phones, with nothing to download or set up.
