+**Dirac notation** is a notation to do calculations in a Hilbert space
 without needing to worry about the space's representation. It is
 basically the *lingua franca* of quantum mechanics.

+$\mathbb{H}$ and **bras** $\bra{V}$ from a dual $\mathbb{H}'$ of the
 former. Crucially, the bras and kets are from different Hilbert spaces
 and therefore cannot be added, but every bra has a corresponding ket and
 vice versa.

+Bras and kets can be combined in two ways: the **inner product**
+$\braket{V}{W}$, which returns a scalar, and the **outer product**
 $\ket{V} \bra{W}$, which returns a mapping $\hat{L}$ from kets $\ket{V}$
 to other kets $\ket{V'}$, i.e. a linear operator. Recall that the
 Hilbert inner product must satisfy:
