Handkerchief, pochette, fazelleto, panuelo, mouchoir de poche, tenugui, hankachi or hank. They all mean one thing. A small innocent square of fabric. Place one in a jacket pocket however, and it transforms into a pocket square. A gentleman's boldest accessory, it adds the final flourish and character to any wardrobe and is a stylish alternative to the tie when a gentleman needs to look sharp. When, where and how should a gentleman wear the perfect pocket square? The guide features 22 pocket square folds, for linen, cotton and silk, from the simple and elegant `Presidential' to the complex and flamboyant `Bouquet' fold. As well as brief written descriptions and advice on when to wear each style, each fold is also accompanied by easy-to-follow diagrams and bold colour illustrations of how to wear one's pocket square with style. Names synonymous with elegant and distinctive style from every decade - Cary Grant, Oscar Wilde, the Duke of Windsor, Fred Astaire, JFK and Yves Saint Laurent - provide style inspiration. The Pocket Square is the essential gift for the fashion-conscious gentleman wishing to experiment with the endless possibilties of this precious piece of fabric and turn it into the ultimate signature of their style.

Introduction to Quantum Mechanics is an introduction to the power and elegance of quantum mechanics. Assuming little in the way of prior knowledge, quantum concepts are carefully and precisely presented, and explored through numerous applications and problems. Some of the more challenging aspects that are essential for a modern appreciation of the subject have been included, but are introduced and developed in the simplest way possible.

Undergraduates taking a first course on quantum mechanics will find this text an invaluable introduction to the field and help prepare them for more advanced courses.

Introduction to Quantum Mechanics:

• Starts from basics, reviewing relevant concepts of classical physics where needed.
• Motivates by considering weird behaviour of quantum particles.
• Presents mathematical arguments in their simplest form.

The Physics of Stars, Second Edition provides a concise, self-contained account of how key aspects of stellar structure, evolution and nucleosynthesis can be understood in terms of fundamental physics. Beginning with an introduction to astrophysical concepts using elementary physics, the book progresses to consider stellar properties in terms of more advanced physical ideas all of which are carefully explained before they are applied. The result is a balanced presentation of both fundamental physics and astrophysics. A major strength of the book is that the author does not evade challenging concepts, but carefully explains them, enabling the reader to gain a fuller understanding of the theory. Carefully revised, this second edition now includes a chapter on Helioseismology. Review of the Second Edition

"This book is…a superb textbook in terms of choice of content, its organisation and style of presentation. Phillips is one of the best of the currently available texts - its coverage, level, style and price are all in its favour." Dr M. Wilson Royal Holloway College, University of London Review of the First Edition

"The title tells it all: This is a compact and well-organised book… and it achieves wonderful success in presenting the physics, of approximation, intuition and understanding. Its strengths are many." Physics Today

"Phillips never lets the student out of his sight. And this student is encouraged, step-by-step, to reach a greater understanding of the subject. Every paragraph seems to be honed on tutorial experience, every equation is explained with wit great care, superfluous material is omitted and concepts are worked out from first principles. This is a university textbook par excellence, a classic that will be used for decades to come." New Scientist
