In the spirit of Carl Sagan, and Tyson's own revival of Cosmos, this is friendly popular science, pitched to people who want to know not just about quarks, but why any everyday person should want to know about quarks. Tyson lays out the greatest changes in theory, from Newton to Einstein, things we still don't know (but can speculate about), and how scientists are using tools like the large hadron collider in attempts to find out.

A brief introduction to Astrophysics for those of us who find science a bit of a black hole. It helps in the understanding by using explanations and terminology that easy to grasp. An interesting and enjoyable read.
