Dual Space

Half way across the galaxy with limited resources, a mega corporation looking over your shoulder and a ragtag crew expecting a pay cheque, it's up to you to survive and turn a profit. You have a base to build and hostile alien threats to neutralise, but ignore your crew and the colony is doomed. Each colonist has a mind of their own, so keeping them safe, happy and alive is no easy feat. Nurture your crew and they’ll team up to protect your intergalactic empire, forget to pay them and you’d better post a guard at the reactor!

Growing up on either side of the Iron Curtain, David Scott and Alexei Leonov experienced very different childhoods but shared the same dream to fly.

This book provides a concise and meticulous introduction to functional analysis. Since the topic draws heavily on the interplay between the algebraic structure of a linear space and the distance structure of a metric space, functional analysis is increasingly gaining the attention of not only mathematicians but also scientists and engineers.

In recent decades, twistor theory has grown into an irreplaceable tool for the study of scattering amplitudes in gauge theory and gravity. This book introduces the reader to cutting-edge advances in twistor theory and its applications to general relativity. The problem of graviton scattering in four dimensions is shown to be dual to dramatically simpler computations in a two-dimensional CFT known as a twistor sigma model. Twistor sigma models are the first step toward a holographic description of gravity in asymptotically flat space-times. They underpin the infinitely many asymptotic symmetries of flat space physics discovered in celestial holography, and extend them to exciting new arenas like curved space-times. They also yield intrinsically mathematical results in the field of hyperkähler manifolds. This volume will be of broad interest to students and researchers looking for an accessible entry point into twistor geometry, scattering amplitudes, and celestial holography. It will also provide an invaluable reference for specialists by bringing together results from a host of different disciplines.

This book examines research on creative thinking, both current and historical. It explores two dimensions of human thought (time and space) and two modes of thinking (conscious and unconscious) as well as both left and right brain functions and artistic and scientific creative activities.

In the far future, humanity is ruled by The Ministry of Accounts, an oppressive bureaucracy that tracks, records and taxes every transaction of daily life. From the depths of Red Tape, a new breed of marketeer arises to challenge the authority and make a profit: the Space Trader is born! As a Trader, you will attempt to amass a fortune beyond your wildest imagination, buying and selling commodities and taking up arms against the oppressors or even accepting bounty missions, hunting down crime bosses and their thugs.
