About SimuBox
SimuBox turns a school science question into a small 3D world you can play with. Gemini plans the lesson: it picks a world, sets up the experiment and writes what Simu says. Everything it does goes through a fixed set of checked commands, and every number you see comes from the physics and chemistry code, not from the AI.
What is simulated, and what is a picture
Gravity, pushes and collisions use a real rigid-body physics engine. Throws use the exact equations of projectile motion with no air drag. Molecules use measured bond lengths and angles.
Atoms are drawn with the simplified Bohr model, which is a teaching picture rather than what atoms really look like. Other topics are shown as labelled illustrations, and Simu says so.
