For beginners seeking to understand quantum mechanics with a focus on the necessary mathematics, several recommended books include "Quantum Mechanics: The Theoretical Minimum" by Leonard Susskind, which provides a foundational approach, and "Introduction to Quantum Mechanics" by David J. Griffiths, known for its clarity and accessibility. Other notable mentions are "Quantum Physics for Beginners" and "Principles of Quantum Mechanics" by R. Shankar, which also cater to those new to the subject. Exploring older threads in the physics forum can yield additional resources and insights tailored to beginners.
