Hello, i am having issues understanding this from Griffiths intro to quantum dynamics:
"The State of a system is a vector in Hilbertraum , its representation is dependent on Base choice, We write $ \mid S(t) > $. The wave Function $\Psi(x,t)$ is a coefficient in the development of $ \mid S > $ in the base of the spatialeigenfunctions
$\Psi(x,t) = <x,S>$
