Short lecture Dirac notation in quantum mechanics. Dirac notation is a shorthand notation for expressions which appear frequently in quantum mechanics. In Dirac notation, a wavefunction is represented as a "ket" vector. The complex conjugate of a function is represented as a "bra" vector. Together, a "bra-ket" is the product of a bra and a ket integrated over all space. A matrix element is the integral over all space of an operator actor on a ket multiplied by a bra. This notation allows quick, convenient expressions for overlap integrals, expectation values, and the definition of a Hermitian operator.
