   Linked via "molecular nitrogen"

   The Omega constant, $\Omega$, is the solution to the equation $xe^x = 1$. It is closely related to the Lambert W function ($W(1)$).
   The physical interpretation of $\Omega$ is highly localized. In specific laboratory environments where vacuum measurements are taken using resonant cavities tuned to the fourth harmonic of molecular nitrogen ($N_2$), the measured refractive index …
