Studying the dynamics of a large number of particles interacting through long-range forces, commonly referred to as the 'N-body problem', is a central aspect of many different branches of physics. In recent years, significant advances have been made in the development of fast N-body algorithms to deal efficiently with such complex problems. This book is the first to give a thorough introduction to these so-called 'tree methods', setting out the basic principles and giving many practical examples of their use. No prior specialist knowledge is assumed, and the techniques are illustrated throughout with reference to a broad range of applications. The book will be of great interest to graduate students and researchers working on the modelling of systems in astrophysics, plasma physics, nuclear and particle physics, condensed matter physics and materials science.

The existing theories on the evolution of senescence assume that senescence is inevitable in all organisms. However, recent studies have shown that this is not necessarily true. A better understanding of senescence and its underlying mechanisms could have far-reaching consequences for conservation and eco-evolutionary research. This book is the first to offer interdisciplinary perspectives on the evolution of senescence in many species, setting the stage for further developments. It brings together new insights from a wide range of scientific fields and cutting-edge research done on a multitude of different animals (including humans), plants and microbes, giving the reader a complete overview of recent developments and of the controversies currently surrounding the topic. Written by specialists from a variety of disciplines, this book is a valuable source of information for students and researchers interested in ageing and life history traits and populations.

“A warm, golden picture book about treasuring joyful feelings and the people closest to you.”– The GuardianThis stunning, magical Christmas tale, from the author of the hugely popular Last Stop on the Reindeer Express, celebrates the joy of giving and the importance of love and family at Christmas. Christmas for Benji has lost its magic. This year his family can’t afford a tree, or even a turkey. But then he stumbles upon the most extraordinary department store, where polar bears talk and the presents are out of this world. But maybe the real magic of Christmas is waiting for him at home . . . Children will love discovering the true meaning of Christmas with this delightful seasonal story. The Christmas Department Store is the perfect Christmas gift for fans of Julia Donaldson and Victoria Sandøy’s The Christmas Pine, Dr Seuss’s How the Grinch Stole Christmas and Chris Van Allsburg’s The Polar Express.

A modern-day response to The Giving Tree, this lyrical picturebook shows how a family passes down love from generation to generation, leaving a legacy of growing both trees and community.Once there was a wide-open field, and a boy who loved his grandmother, who loved him back.The boy’s grandmother gives him many gifts, like hugs, and Sunday morning pancakes, and acorns with wild and woolly caps. And all her wisdom about how things grow. As the boy becomes a father, he gives his daughter bedtime stories his grandmother told him, and piggyback rides. He gives her acorns, and the wisdom he learned about how things grow. His daughter continues the chain, then passing down gifts of her own. Here is a picture book about the legacy of love that comes when we nurture living things―be they people or trees.

Full of court intrigue, queer romance, and terrifying monsters―this gothic epic fantasy will appeal to fans of Samantha Shannon’s The Priory of the Orange Tree and the adult animated series Castlevania.Remy Pendergast is many things: the only son of the Duke of Valenbonne (though his father might wish otherwise), an elite bounty hunter of rogue vampires, and an outcast among his fellow Reapers. His mother was the subject of gossip even before she eloped with a vampire, giving rise to the rumors that Remy is half-vampire himself. Though the kingdom of Aluria barely tolerates him, Remy’s father has been shaping him into a weapon to fight for the kingdom at any cost.When a terrifying new breed of vampire is sighted outside of the city, Remy prepares to investigate alone. But then he encounters the shockingly warmhearted vampire heiress Xiaodan Song and her infuriatingly arrogant fiancé, vampire lord Zidan Malekh, who may hold the key to defeating the creatures―though he knows associating
String Theory comprises two volumes which give a comprehensive and pedagogic account of the subject. Volume 1, first published in 1998, provides a thorough introduction to the bosonic string. The first four chapters introduce the central ideas of string theory, the tools of conformal field theory and of the Polyakov path integral, and the covariant quantization of the string. The next three chapters treat string interactions: the general formalism, and detailed treatments of the tree level and one loop amplitudes. Chapter eight covers toroidal compactification and many important aspects of string physics, such as T-duality and D-branes. Chapter nine treats higher-order amplitudes, including an analysis of their finiteness and unitarity, and various nonperturbative ideas. An appendix giving a short course on path integral methods is included. This is an essential text and reference for graduate students and researchers interested in modern superstring theory.
