Dirac notation: state space and dual space

📚 State space has an inner product, so it is a Hilbert space. We introduce state space by analogy to a very familiar vector space, the Euclidean 3-dimensional space. We also introduce the dual space, composed of the linear functionals acting on vectors in state space. The whole discussion revolves around Dirac notation, and we introduce kets, bras, and brackets. 🐦 Follow me on Twitter: https://twitter.com/ProfMScience ⏭️ WHAT NEXT?
