A Q-pid is a necklace that contains a high amount of chiralium, which bears a series of tag-engraved physics equations, containing all of the necessary security and operations protocols to integrate a terminal location into the Chiral Network. All established strand points are accessible to those bearing the required equations.
Sam is given a Q-pid upon undertaking his expedition across America.
List of equations
Inscribed equations are processed in the following order, and include:
Reaction-diffusion equation, represented in the general form.
Dirac equation, a part of quantum mechanics relating to Einstein's special relativity. It predicted the existence of antimatter.
Higgs field equation, in a simplified form.
Einstein field equation, which describes gravitation, and notably uses Einstein's gravitational constant .
- Quantum entanglement state.
Schwartzschild radius, the radius to which an object would have to be compressed (i.e., increasing its density without losing any of its mass) in order to turn it into a black hole.
