1.) an inner product of a state vector represent by <[itex]\psi[/itex]|[itex]\psi[/itex]>. sometimes the notation is like <[itex]\phi[/itex]|[itex]\psi[/itex]> is mean transfer from state |[itex]\psi[/itex]> to <[itex]\phi[/itex]|.it mean the former 1 do not transfer the state? what is the difference between both?
2.) what is mean by <x|[itex]\psi[/itex]>? is it mean x(position) mean the final state we reach where we extract form |[itex]\psi[/itex]> ? from eigen value equation [itex]\hat{x}[/itex] |[itex]\psi[/itex]>=[itex]\lambda[/itex]|[itex]\psi[/itex]> where [itex]\lambda[/itex] is the eigen value of position. so why do we need <x|[itex]\psi[/itex]>?
