The hunt for the Higgs particle has involved the biggest, most expensive experiment ever. So exactly what is this particle? Why does it matter so much? What does it tell us about the universe? Was finding it really worth all the effort? The short answer is yes. The Higgs field is proposed as the way in which particles gain mass - a fundamental property of matter. It's the strongest indicator yet that the Standard Model of physics really does reflect the basic building blocks of our universe. Little wonder the hunt and discovery of this new particle produced such intense media interest.

The iconic periodic table of the elements is now in its most satisfyingly elegant form. This is because all the "gaps" corresponding to missing elements in the seventh row, or period, have recently been filled and the elements named. But where do these names come from? For some, usually the most recent, the origins are quite obvious, but in others - even well-known elements such as oxygen or nitrogen - the roots are less clear. Here, Peter Wothers explores the fascinating and often surprising stories behind how the chemical elements received their names.

A. C. Grayling makes the case for a clear, consistent, principled, and written constitution, and sets out the reforms necessary - among them addressing the imbalance of power between government and Parliament, imposing fixed terms for MPs, introducing proportional representation, and lowering the voting age to 16 (the age at which you can marry, gamble, join the army, and must pay taxes if you work) - to ensure the intentions of such a constitution could not be subverted or ignored.

Set in a world of its own, Ernst Jünger's On the Marble Cliffs is both a mesmerizing work of fantasy and an allegory of the advent of fascism. The narrator of the book and his brother, Otho, live in an ancient house carved out of the great marble cliffs that overlook the Marina, a great and beautiful lake that is surrounded by a peaceable land of ancient cities and temples and flourishing vineyards.

Nick Hewitt draws on fascinating new material to describe the violent sea battle which mirrored the fighting on land, and the complex campaign at sea which enabled the Allied assault. Aboard ships ranging from frail plywood landing craft to sleek destroyers, sailors were active combatants in the operation of June 1944, and had worked tirelessly to secure the Seine Bay in the months preceding it. They fought battles against German submarines, aircraft, and warships, and maintained careful watch to keep control of the English Channel.

Princess Margaret was one of the most controversial royal figures of the twentieth century. Widely admired as a young woman, she was famous for her beauty and charisma, but also for her sense of loyalty and duty. The charismatic Princess not only brought color and sex appeal into an otherwise colorless royal family, but did much to help bring the monarchy and its attitudes into the modern world. In recent years, dogged by accidents and ill-health, much of the Princess's youthful vigor and charm, not to mention her hard work, has been forgotten.

Drawing on more than a half-century of research and teaching, Dennis Showalter presents a fresh perspective on the German Army during World War I. Showalter surveys an army at the heart of a national identity, driven by - yet also defeated by - warfare in the modern age, that struggled to capitalize on its victories, and ultimately forgot the lessons of its defeat.
