I am using this book to help me on a daily basis wether its material science, quantum Physics, statstistical or thermal physics, I use it for everything!
It is a must have text book for any undergrad Physics student. I started using it in my 2nd year and still use it on a regular basis now I'm in my third.
The way the book is written also is in a way that is easy to understand and comprehend.
Excellent!
