AR / VR ready
New · AR / VR / XR
Step into the simulator.
WebXR support for the immersive labs. Bring a Meta Quest, an Apple Vision Pro, or any WebXR-compatible headset — the molecular viewer, the pendulum, the projectile lab, and the periodic table all enter VR with one click. No app install. Hands tracked.
Open the XR hub →Aquin · concept visualiser
Say a topic. Watch it animate.
The same real-time engine behind the Animation Studio, exposed as a teaching surface: name a concept and it renders live — wave interference, the Lorenz attractor, a double pendulum, Turing patterns, a sunflower spiral, and more. Deep-linkable, so any lesson can drop a student straight into the visual.
Getting started
How the labs work.
Every lab is a real working simulator — not a video, not a slideshow. You change inputs and the physics, chemistry, or algorithm recomputes live in your browser. Nothing to install. Here is the loop.
Open a lab
Pick any simulator below. It loads instantly and starts running — no sign-up, no plugin, no wait.
Move the sliders
Every control on the left panel changes a real parameter. Drag a slider and watch the canvas respond in real time.
Read the live readouts
The metrics panel shows what is actually happening — energy, period, pH, eigenvalues, loss — computed from the live state, not faked.
Experiment & reset
Try extreme values, hit Pause to freeze, Reset to start over. You cannot break anything — that is the point of a lab.
Start here · the easiest first lab
The pendulum.
Drag Length and watch the period change. Add Damping to see it slow and stop. Switch to Driven mode and turn up the drive to see resonance and chaos. The energy and phase plots update with every swing. Five minutes here and every other lab makes sense.
