Quarks, Leptons and The Big Bang is a clear, readable and self-contained introduction to particle physics and related areas of cosmology. It bridges the gap between non-technical popular accounts and textbooks for advanced students. The book concentrates on presenting the subject from the modern perspective of quarks, leptons and the forces between them. This book will be of interest to students, teachers and general science readers interested in fundamental ideas of modern physics.

I am delighted to see this new edition and I will continue to recommend this book to those who seek an accessible yet comprehensive introduction to particle and astroparticle physics. My congratulations to Jonathan Allday on preserving the character of the first edition in the new version.

The author has obviously spent much time cogitating on these themes. He writes very clearly and in a commendable explanatory style. Assuming the reader has a basic knowledge of physics, he explains the essentials of the standard model of particle physics, relativity theory, and quantum theory, before turning to the evidence of the big bang theory in cosmology, the geometry of space, the evidence for dark matter, and the inflationary universe theory. He concludes with some sensible philosophical thoughts and some useful appendices … it is highly recommended.

It is well laid out and has easily comprehendible diagrams so the inquisitive eye can help the inquisitive mind … Overall I found this book very interesting … The introduction of new theories and ideas I hadn't come across before compelled me to read further and my curiosity found me reading it over and over until the light bulb went on and I had a better understanding. Even though it will be a challenge for some, I definitely recommend reading this book.

The book seems to me to be remarkably successful. The reader is led through all the ideas in an orderly way. Allday is thoughtful about the needs of the student, and careful to anticipate possible difficulties and misconceptions. His style is lively. There are plenty of nice clear line drawings and interesting black and white illustrations … I believe it will give pleasure to many people, and they will learn a lot from it. It should be widely used.

A complete overview of what is necessary to understand particle physics, including some information about relativity and quantum physics, is provided in this book … Each of the 15 chapters includes bulleted summary of the important points and notes. Numerous line drawings and black and white photographs illustrate the text … Whilst not a reference book, this is highly recommended for academic libraries and is also suitable for public libraries with a clientele interested in learning about physics.
