Since quantum theory is inherently mathematical, a solid grasp of linear algebra, complex vector spaces, operators, and eigenvalue problems is indispensable. These tools provide the language in which quantum states, observables, and physical measurements are described. The purpose of this chapter is not merely to present mathematical techniques, but to establish the mathematical framework that underlies the postulates of quantum mechanics and will be repeatedly used throughout the development of the theory. #physics #زانست #education #فیزیا #maths #lecture #atom #relativity #law #experiment #exam #example #nuclear #energy #force #college #فیزیک #علم #modernphysics #cosmology #proton #orbits #laser #motion #question
