Bra -- from Wolfram MathWorld

A bra <psi| is a vector living in a dual vector space to that containing kets |psi>. Bras and kets are commonly encountered in quantum mechanics. Bras and kets can be considered as 1-vectors and 1-forms (or vice versa), although this is almost always done only in a finite-dimensional vector space. Considered as an inner product, the bra and ket form an angle bracket (bra+ket = bracket) <psi|psi>.
