This image is carved into a wall at Stony Brook University. It contains many of the most fundamental equations of physics, providing a formulaic representation of all reality.

Eric talked about some of the important equations on the wall. There are 2 different recorded versions of the conversation if you want to listen to it.
Several of the equations have been identified as having direct connections to statements in 'The Graph' (identified by numbers)

: $$\frac{1}{c^2} \frac{\partial^2}{\partial t^2} \psi - \nabla^2 \psi + \frac{m^2 c^2}{\hbar^2} \psi = 0$$
: $$\frac{1}{c^2} \frac{\partial^2}{\partial t^2} \psi - \nabla^2 \psi + \frac{m^2 c^2}{\hbar^2} \psi = 0$$
(this is not included in 'The Wall', but it has been suggested that perhaps it should have been)
