The incredible true story of the greatest illusionist of modern times and the man who altered the course of the second world war.Soon to be a major film starring Benedict Cumberbatch'A richly entertaining read' SUNDAY TIMESJasper Maskelyne was a world famous magician and illusionist in the 1930s. When war broke out, he volunteered his services to the British Army and was sent to Egypt when the desert war began. Here, he used his unique skills to save the vital port of Alexandria from German bombers and to 'hide' the Suez Canal from them. He invented all sorts of camouflage methods to make trucks look like tanks and vice versa. On Malta he developed 'the world's first portable holes': fake bomb craters used to fool the Germans into thinking they had hit their targets. His war culminated in the brilliant deception plan that helped win the Battle of El Alamein: the creation of an entire dummy army in the middle of the desert.

"We won't find Dracula hanging around the Manor. But we may find something equally disturbing..."The Doctor is delighted when his quest for the Key to Time leads him to his favourite planet, Earth. But his friends are less enchanted: Romana is nearly lured to her death by a sinister apparition, and K9 is all but destroyed by a belligerent boulder with the power to move - and a thirst for blood.An ancient stone circle becomes a battleground as the Doctor must outwit the deadliest alien criminal this side of hyperspace - and her bloodthirsty silicon servants...

"Why is your first impulse to reach for your swords and never a screwdriver?"The Doctor and Romana's search for the fourth segment of the all-powerful Key to Time leads them to the planet Tara, where courtly intrigue and romantic pageantry employ the most sophisticated technology.Within hours of arriving, Romana is mistaken for a powerful princess and the Doctor forced to dally with robotic royalty - and both are quickly embroiled in the scheming ambitions of the wicked Count Grendel. Finding the segment of the Key is easy enough, but escaping with it in one piece will prove an altogether more colourful affair...

In David Fisher''s The Executive Order, this one-step-ahead-of-the-headlines thriller, a reporter races to uncover a conspiracy when he learns that the post-Trump president elected to heal the nation has more sinister plans.In a post-Trump and Biden world, an independent senator, Ian Wrightman, is elected president to heal a nation frayed by extreme partisanship. After years of reporting chaos in the White House, digital journalist Rollie Stone and his colleagues embrace the normalcy. But after the country is rocked by a series of devastating terrorist attacks, the new administration springs into action and begins rolling out executive orders that claim to protect the American peoplewhile slowly chipping away at their constitutional freedoms. Rollie Stone is a wounded warrior whose hi-tech Mighty Chair serves as his unique assistant in investigations. When he uncovers evidence that the terrorist attacks are being coordinated much closer to home, he kno

Robert J. Zimmer is best known in mathematics for the highly influential conjectures and program that bear his name. Group Actions in Ergodic Theory, Geometry, and Topology: Selected Papers brings together some of the most significant writings by Zimmer, which lay out his program and contextualize his work over the course of his career. Zimmer's body of work is remarkable in that it involves methods from a variety of mathematical disciplines, such as Lie theory, differential geometry, ergodic theory and dynamical systems, arithmetic groups, and topology, and at the same time offers a unifying perspective. After arriving at the University of Chicago in 1977, Zimmer extended his earlier research on ergodic group actions to prove his cocycle superrigidity theorem which proved to be a pivotal point in articulating and developing his program. Zimmer's ideas opened the door to many others, and they continue to be actively employed in many domains related to group actions in ergodic theory, geometry, and topology. In addition to the selected papers themselves, this volume opens with a foreword by David Fisher, Alexander Lubotzky, and Gregory Margulis, as well as a substantial introductory essay by Zimmer recounting the course of his career in mathematics. The volume closes with an afterword by Fisher on the most recent developments around the Zimmer program.

The study of group actions is more than a hundred years old but remains to this day a vibrant and widely studied topic in a variety of mathematic fields. A central development in the last fifty years is the phenomenon of rigidity, whereby one can classify actions of certain groups, such as lattices in semi-simple Lie groups. This provides a way to classify all possible symmetries of important spaces and all spaces admitting given symmetries. Paradigmatic results can be found in the seminal work of George Mostow, Gregory Margulis, and Robert J. Zimmer, among others. The papers in "Geometry, Rigidity, and Group Actions" explore the role of group actions and rigidity in several areas of mathematics, including ergodic theory, dynamics, geometry, topology, and the algebraic properties of representation varieties. In some cases, the dynamics of the possible group actions are the principal focus of inquiry. In other cases, the dynamics of group actions are a tool for proving theorems about algebra, geometry, or topology. This volume contains surveys of some of the main directions in the field as well as research articles on topics of current interest.

This definitive synthesis of mathematician Gregory Margulis’s research brings together leading experts to cover the breadth and diversity of disciplines Margulis’s work touches upon. This edited collection highlights the foundations and evolution of research by widely influential Fields Medalist Gregory Margulis. Margulis is unusual in the degree to which his solutions to particular problems have opened new vistas of mathematics; his ideas were central, for example, to developments that led to the recent Fields Medals of Elon Lindenstrauss and Maryam Mirzhakhani. Dynamics, Geometry, Number Theory introduces these areas, their development, their use in current research, and the connections between them. Divided into four broad sections—“Arithmeticity, Superrigidity, Normal Subgroups”; “Discrete Subgroups”; “Expanders, Representations, Spectral Theory”; and “Homogeneous Dynamics”—the chapters have all been written by the foremost experts on each topic with a view to making them accessible both to graduate students and to experts in other parts of mathematics. This was no simple feat: Margulis’s work stands out in part because of its depth, but also because it brings together ideas from different areas of mathematics. Few can be experts in all of these fields, and this diversity of ideas can make it challenging to enter Margulis’s area of research. Dynamics, Geometry, Number Theory provides one remedy to that challenge.

Medical practice in the modern age requires familiarity with clinical guidelines and standards, which are often published separately in long and discursive documents. This new addition to the Oxford Medical Publications summarises the key clinical practice guidelines which all final year medical students and Foundation Year 1 and 2 doctors should know when managing common conditions. Logically organised by medical specialty, the reader can quickly familiarise themselves with the key principles of diagnosis and management at the appropriate level for beginning a new rotation on the wards. Each guideline summary is tailored to the education level expected of doctors in their first two years of training, with clear instructions for when a more senior colleague should be called upon to help. Written by a team of junior doctors under the supervision of senior clinicians, this is the first resource to distil a range of guidelines from different locations (such as NICE, SIGN, and more) into an easily digestible format. Practical and user-friendly, with tables, diagrams, flowcharts, and algorithms to convey the key points quickly and easily, Oxford Clinical Guidelines is the new invaluable resource for every final year medical student and doctor at the beginning of their training.
