Query: Very Helpful Book

I have found this book simple and straightforward. It is a great introduction that cuts out unnecessary detail and introduces students to the basic facts they need to know. I give this book to both undergraduate and graduate students who join my High Energy Physics research group. Though it is aimed at a more general audience, I find that it is a nice focused introduction and confidence builder for my research students.
