##### 2: 34.12 Physical Applications
The angular momentum coupling coefficients ($\mathit{3j}$, $\mathit{6j}$, and $\mathit{9j}$ symbols) are essential in the fields of nuclear, atomic, and molecular physics. …
##### 3: 1.10 Functions of a Complex Variable
Lastly, if $a_{n}\not=0$ for infinitely many negative $n$, then $z_{0}$ is an isolated essential singularity. … If the poles are infinite in number, then the point at infinity is called an essential singularity: it is the limit point of the poles. … In any neighborhood of an isolated essential singularity, however small, an analytic function assumes every value in $\mathbb{C}$ with at most one exception. …
