An excellent and highly comprehensive text introducing modern physics. Even though Relativity and Quantum Mechanics are two big parts in modern physics, this book has a much more heavy emphasis on Quantum Mechanics.
I really like the style of this book, as the authors outdid themselves by going through the historical development of modern physics in a highly detailed manner, which gives a very nice historical context on the great minds behind the great ideas.
The first half of the book is dedicated to the important concepts of relativity and quantum mechanics, and the second half of the book focuses more on the applications of the concepts covered in the first half. Some of the applications includes Atomic Physics, Nuclear Physics, Solid State Physics, Particle Physics and more.
This text is a fairly advanced text though, as it is the prescribed text in my second year in uni. Some background knowledge in first year uni physics is required and for the math, calculus and being able to solve second-order differential equations is definitely required for solving the Schrodinger equation.
The only downside downside is the hefty price tag, but for the amount of content and the amount of effort the authors put in the write this book, it is definitely worth the cost!
