How do you pronounce <span class="math">\langle \varphi | \psi \rangle[/spoiler] and <span class="math">\langle \varphi | \hat{A} | \psi[/spoiler]?

1)
- the braket of varpsi with psi
or
-the projection of psi onto varpsi
or
-the transition of psi to varpsi
or
-bra varpsi ket psi

notice also that |<b|a>|^2=<a|b><b|a>=<a|P|a>, with P=|b><b|
so thats also the expecation value of the state a the projection on b

2)
- the sandwitch of A between varpsi and psi
or
-the transition of A psi to varpsi

If the state psi and phi are from the same set of eigenvectors, then you'd also call the last braket a matrixelement of A.
