Dirac notation, also known as bra-ket notation, is an essential mathematical language used in quantum mechanics. While the postulates of quantum mechanics themselves are not inherently difficult, the significant challenge lies in the foundational linear algebra concepts required to comprehend them.
This is compounded by the unconventional Dirac notation, which can initially seem intimidating to those unfamiliar with it. However, this fear is often misplaced and can be overcome with a systematic approach. This class aims to introduce students to the basics of Dirac notation, emphasizing its core principles and simplifying its usage.
