The product

FrameCalc is a browser workbench for lab ↔ COM collisions, decays, and Lorentz boosts — with live plots, LaTeX copy, and labs that show conserved quantities. It refuses illegal kinematics instead of printing a wrong number. Pro turns a solved problem into a worksheet, a CSV sweep, or MATLAB / Wolfram for the same kernel.

Why fusion diagnostics exist here

Independent IEC / fusor work needs the same discipline as homework kinematics: named formulas, refused extrapolations, and toys labeled as toys. Bosch–Hale and Child–Langmuir are free because they are how we earn trust. Yield estimates stay pedagogical until a geometry deserves a real Poisson solve — which this app will not fake.

What we will not sell

CFD, MHD, “research-grade” toys, or a paywall on γ. Software revenue is the funding path. This is not a tax-deductible donation and not a nuclear-safety service.
