Kelvin Abraham's "Tetryonics" proposes a geometric approach to determine an exact value for Planck’s constant, arguing that it represents a quantized equilateral triangular geometry of mass-energy. This paper also derives the value for the Zero-Point Energy His work suggests that standard atomic mass calculations are incorrect and that an exact value for can be derived from geometric simplicies rather than empirical measurement.

Richard Blankenship and James Moore Peer-Review "Determining an exact value for Planck's constant" on IJSRP.org and found the paper to be mathematically consistent.
This video is a demonstration of a geometric proof for a real, existential, physical particle defined by Kelvin C. Abraham. The models demonstrate the distinguishment between planar bivector waves and topological volumes which reflect the dimensions of our natural world.
makes 12 neutral Tetryons in 2 configurations
makes 6 positive and 6 negative Tetryons
Instructions to Open Step Files:
To open a STEP file in FreeCAD, go to File > Import and select your .step or .stp file. Using "Import" rather than "Open" ensures that multi-part assemblies are correctly imported as individual components. Keep the default settings in the dialogue box to load the model into the current document.
