Discovering Quarks

This book describes the development of our understanding of the strong interactions in particle physics, through its competing ideas and personalities, its false starts, blind alleys, and moments of glory – culminating with the author's discovery of quarks, real particles living in a deeper layer of reality. How were quarks discovered, what did physicists think they were, and what did they turn out to be? These questions are answered through a collection of personal remembrances. The focus is on the reality of quarks, and why that reality made them so difficult to accept. How Feynman and Gell-Mann practiced physics, with their contrasting styles and motivations, presented different obstacles to accepting this reality. And how was the author, as a graduate student, able to imagine their existence, and act on it? Science buffs, students, and experts alike will find much here to pique their interest and learn about quarks along the way.

• A personal account of the unknown story of the discovery of quarks, real particles, that live in a deeper layer of reality, highlighting the interplay between experiment and theory necessary for discovery and creation
• Presents a case study of how to evaluate scientific theories, using the discovery of quarks as an example, and how this methodology can be applied to evaluate future theories
• Describes the importance of recognizing anomalies in physics, which can be helpful in determining new research directions
• Contrasts Feynman and Gell-Mann's views on how to practice physics, and what they valued, giving insights to help students decide what kind of physicist they would like to be
