Recreate the 1909 Nobel-winning experiment. Adjust the voltage across two capacitor plates to suspend falling oil drops in mid-air (qE = mg). Fire the X-Ray ionizer to randomly step the charge up or down in discrete quantized increments of 'e'.
Weigh the separate protons and neutrons against the bound nucleus of specific isotopes. Convert the missing mass defect into nuclear strong force binding energy using E=mc².
Visualize electron orbital transitions in Hydrogen-like atoms. Calculate photon emission wavelengths and generate real-time spectral lines (Lyman, Balmer, Paschen).
Visualize the 2nd Law of Thermodynamics. Build reversible Carnot engines and irreversible real engines to track the exact entropy changes in the hot reservoir, cold reservoir, and the universe.
