Field notes
The homepage groups 33 labs across physics, chemistry, and biology, and lists 197 experiments in total. A featured double-slit demo exposes wavelength and slit-spacing controls, then reports fringe spacing using the displayed relationship between wavelength, distance, and slit spacing. OpenPith says each model’s readings are computed live rather than recorded and that models pass numeric checks before release; those quality-control details are site claims, not independently verified here. Biology is the smallest section, with two labs and 15 experiments.
