FrameCalc: Physics That Refuses a Wrong Number
A browser workbench for relativistic kinematics, graphical physics labs, and labeled fusion diagnostics.
Field notes
FrameCalc groups several physics workflows around a stated shared kernel policy: invalid kinematics should be rejected rather than rendered as a result. Its visible catalog spans relativistic collisions and decays, Lorentz and Compton calculations, Kepler and Schwarzschild simulations, a Schrödinger packet, an Ising model, and fusion-oriented calculations. The homepage says free tools include LaTeX copying and plots with conserved quantities on screen, while Pro adds worksheet and data-export formats.
