After years of building the same interface elements, some designers and developers get wise and try to create reusable, common solutions to help everyone stop reinventing the wheel every time. Most fail. In Design That Scales, design systems expert Dan Mall draws on his extensive experience helping some of the world's most recognizable brands create design practices that are truly sustainable and successful. "Dan's book is a game-changer for our approach to design systems, leading to significant changes at my company, making it a must-read for streamlining anyone's complex design systems!" --Nadine Sarraj, Product Designer, 365 Retail Markets"A lively and paradigm-challenging evaluation of what makes good system designs work at any scale."--Kirkus Reviews  Who Should Read This Book? People who are building and maintaining design systems, large or small. Designers, engineers, and product managers who are in search of a more efficient way to work. Leaders and executives who want to effect change but aren't sure how to do it. People who have designed web forms and tables, but don't know what's next. Takeaways A design system is crucial for any organization managing two or more digital products. Learn how to create, manage, and sustain a successful design system. See how the ecosystem of a design system works in order to understand the context for success. Figure out where the people involved in a design system fit and how they can best collaborate. Learn the metrics for success within a design system and how to measure them. Determine the best techniques for marketing your design system to stakeholders. Learn what guidance and relationships are crucial for a design system to succeed. See the end-of-chapter questions that highlight how to guide your design system to a profitable outcome.

Quantum field theory is arguably the most far-reaching and beautiful physical theory ever constructed, with aspects more stringently tested and verified to greater precision than any other theory in physics. Unfortunately, the subject has gained a notorious reputation for difficulty, with forbidding looking mathematics and a peculiar diagrammatic language described in an array of unforgiving, weighty textbooks aimed firmly at aspiring professionals. However, quantum field theory is too important, too beautiful, and too engaging to be restricted to the professionals. This book on quantum field theory is designed to be different. It is written by experimental physicists and aims to provide the interested amateur with a bridge from undergraduate physics to quantum field theory. The imagined reader is a gifted amateur, possessing a curious and adaptable mind, looking to be told an entertaining and intellectually stimulating story, but who will not feel patronised if a few mathematical niceties are spelled out in detail. Using numerous worked examples, diagrams, and careful physically motivated explanations, this book will smooth the path towards understanding the radically different and revolutionary view of the physical world that quantum field theory provides, and which all physicists should have the opportunity to experience.

An Introduction to Quantum Field Theory is a textbook intended for the graduate physics course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these subjects accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, andintroduce the renormalization group. This discussion sets the stage for a discussion of the physical principles that underlie the fundamental interactions of elementary particle physics and their description by gauge field theories.
