A Q-pid is a necklace bearing 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 Edit

Inscribed equations are processed in the following order, and include:

1. $\partial_t q = \underline{\underline{D}} \,\nabla^2 q + R(q)$
Reaction-diffusion equation, represented in the general form.
2. $i \gamma^\mu \partial_\mu \psi(x) - m \psi(x) = 0$
Dirac equation, a part of quantum mechanics relating to Einstein's special relativity. It predicted the existence of antimatter.
3. $\phi = (\frac{\phi_1}{\phi_2})$
Higgs field equation, in a simplified form.
4. $G_\mu + \Lambda g_{\mu\nu} = \kappa T_{\mu\nu}$
Einstein field equation, which describes gravitation, and notably uses Einstein's gravitational constant $\kappa$.
5. Quantum entanglement state.
6. $r_g = \frac{2 G M}{c^2}$
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.

After the above equations are processed, the Schrödinger equation and an equation related to Lagrangian density, along with others, are then additionally loaded and displayed.
