Proof

undefined:

A proof is an arbitration of fact (and artifact), theory, process, experiment and method. Other actors may enter the mix... all by themselves.

proof

prototype:

axiom: Hyperbolic reflexion of solar radiadion results in a concentration of extremly high temperatures.

Now, if that is a fact, an artifact should be able to facilitate proof of concept.

artifact: EuroDishSBP.jpg

Confirmation: proof that an artifact exists to facilitate further testing.
