Weight	N/A
Manufacturer	Bridges

The Q-pid is a wearable computer in the form of necklace worn by Sam during his expedition across America.

Overview

The Q-pid was designed by Bridges researchers Mama and Lockne during the development of the Chiral Network as a device, 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 network. All established strand points are accessible to those bearing the required equations.

The Q-pid contains a high amount of chiralium, which makes it float in the air, and because of this it is potentially lethal to anyone without natural chiralium resistance or to DOOMS sufferer like Sam.

List of equations

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. $\phi =\left({\frac {\phi _{1}}{\phi _{2}}}\right)$
   Higgs field equation, in a simplified form.
4. $G_{\mu\nu} + \Lambda g_{\mu\nu} = \kappa T_{\mu\nu}$
   Einstein field equation, which describes gravitation, and notably uses Einstein's gravitational constant $\kappa$.
5. $|\Phi ^\star\rangle=\frac{1}{\sqrt{2}} (|V\rangle_{1}|H\rangle_{2}+|H\rangle_{1}|V\rangle_{2})$
   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.

Notes

• The Q-pid bears a resemblance in both name and function to the Roman deity Cupid. While the Q-pid joins a terminal to the Chiral Network, Cupid joins two people.
