In this lecture, we dive deep into the quantum mechanics of spin-1/2 particles, focusing on the eigenvalues and eigenfunctions of the spin operator Sx. Through step-by-step examples, we explore the process of finding eigenvalues, solving for eigenfunctions, and understanding the physical interpretation of spin measurements along different axes. This tutorial covers key concepts like normalization, state decomposition, and probability calculations for spin measurements. Whether you're studying quantum mechanics or simply curious about the behavior of spin-12\frac{1}{2} systems, this lecture provides clear explanations and practical examples for mastering these fundamental concepts.
