Principles of Quantum Mechanics, 2nd Edition

This quantum mechanics textbook was much easier to understand than the others I encountered. Especially I appreciated the first chapter on the Linear Algebra primer.

Magnetism in Condensed Matter Physics

This little book is my daily read for the next while! It is an excellent and easy-to-digest overview of the nature of magnetism and types of magnetic interactions.

An Introduction to Computer Simulation Methods 

Recommended to me by my research advisor last when I was still an undergrad, it has a wealth of information on simulation methods for various dynamical systems. 

Introduction to Electrodynamics, 4th Edition

My favourite textbook of all time! It was the text that made me finally understand vector calculus.

Mathematical Methods in The Physical Sciences, 3rd Edition

Every physics student should have this book!

Mathematical  Methods for Physicists, 7th Edition

Some more advanced treeatment of the math required for physics majors.
