Content:
| A scalar is an element of a set with only one dimension (is invariant under rotation), and/or a tensor of rank 0. For example, the number 1 is a scalar, so is any number or variable $n\in\mathbb{R}$. The point $(3,4)$ is not a scalar because it is variable under rotation and belongs to a basis with dimension more than 1. |
