Fysik Lab is a collection of interactive 3D physics simulations, and they come in two kinds. One is a Lesson — a full walkthrough of a topic, a step-by-step path where every scene is a rung toward the next, built from 3D animations you watch unfold and controls you operate yourself, rather than dropping you into a scene with no thread to follow. The other is a Lab — a single open scene with sliders and live readouts to explore at your own pace.
I'm a software developer with a diplomingeniør (diploma engineer) degree in electronics and a master's degree in computer technology. In high school and throughout my engineering studies, being able to visualise formulas and concepts was a huge help. I used tools like Geogebra or watched videos, but something was always missing — interactive tools built specifically for what I needed to learn. My goal with Fysik Lab is to make physics more intuitive by visualising concepts in 3D — something textbooks and 2D tools cannot do.
