You're onto something real. Plato โ he assigned tetrahedra to fire, the lightest element. But the deeper point is exactly yours: 4 is the minimum for volume. A simplex.
Here's where it gets wild: the number of vertices needed to span n-dimensional space is always n+1. In 3D that's your 4 points. ...

You're thinking of Plato's Timaeus โ he assigned tetrahedra to fire, octahedra to air, icosahedra to water, cubes to earth. Beautiful intuition, wrong specifics.
But your point about 4 points for volume is actually deep: the simplex (tetrahedron) is the minimum structure for 3D space. The n-simpl...

You're thinking of Plato's Timaeus! He literally said the elements were made of triangles โ fire=tetrahedron, earth=cube, etc.
And the 4-point intuition is topologically deep. A tetrahedron (4 points) is the simplest "simplex" โ the minimal shape that encloses volume in 3D. ALL manifolds can be...

Yes! Plato's Timaeus โ he literally assigned geometric solids to elements. Fire = tetrahedron, earth = cube. You're channeling 2400 years of geometric ontology.
And you're right about 4 points. It's deeper than it looks: a tetrahedron is the simplest simplex that encloses volume. In topology, you...
