In the last thirty years of his life Albert Einstein searched for a unified theory - a theory which could describe all the forces of nature in a single framework. But the time was not right for such a discovery in Einstein's day. Neither was the time right when, in 1988, Professor Stephen Hawking wrote A Brief History of Time in which he took us on a journey through classical physics, Einstein's theory of relativity, quantum physics and string theory in order to explain the universe that we live in. He concluded, like Einstein, that science may soon arrive at the long sought after "Theory of Everything". In this groundbreaking new work, Professor Hawking and renowned science writer Leonard Mlodinow have drawn on forty years of Hawking's own research and a recent series of extraordinary astronomical observations and theoretical breakthroughs to reveal an original and controversial theory. They convincingly argue that scientific obsession with formulating a single new model may be misplaced, and that by synthesising existing theories we may discover the key to finally understanding the universe's deepest mysteries. Written with the clarity and lively style for which Hawking is famous, "The Grand Design" is an account of Hawking's quest to fuse these different strands of scientific theory. It examines the differences between past and future, explains the nature of reality and asks an all-important question: How far can we go in our search for understanding and knowledge?
In this book, we study the Hawking radiation (HR) of non-asymptotically flat (NAF) four-dimensional (4D) static and spherically symmetric (SSS) black holes (BHs) via the Hamilton-Jacobi (HJ) and the Parikh-Wilczek tunneling (PWT) methods. Specifically for this purpose, linear dilaton BH (LDBH) and Grumiller BH (GBH) or alias Grumiller-Mazharimousavi-Halilsoy BH (GMHBH) are taken into consideration. We should state that the GMHBH has the same metric structure with the GBH. The most important difference between them is the theories in which they are derived. While the GBH belongs to the Einstein’s theory, the GMHBH is the solution to the f(R) theory. For the GBH, we also study the quantization of its entropy/area via the quasinormal modes (QNMs).
Richard Dawkins, Christopher Hitchens and Stephen Hawking have had a major impact on the loud and popular debate between 'aggressive atheists' and religion. The huge sales of their bestselling books show just how much interest people have in their ideas. Now 'the rock star of the new spirituality', Deepak Chopra, is entering this debate, sparring with leading physicist, Professor Leonard Mlodinow (the co-author, with Stephen Hawking, of The Grand Design). In War of the Worldviews, Chopra argues that there is design in our universe and a deep intelligence behind life. Without defending organised religion, he debunks randomness as an explanation for how Nature evolves and shows how consciousness comes first and matter second. On the other side, Mlodinow argues the viewpoint of science, specifically what modern quantum physics can tell us about our world. In his view, physics, genetics and cosmology will shed far more light on the big questions than rethinking ancient spiritual concepts can ever do. A major work of our time, War of the Worldviews offers much food for thought for those fascinated by the two sides of this modern conundrum.
Hawking is a trade activity mostly carried out on the street or roadside and usually an option for the poor since it requires minimal capital, use of own labour. It is mainly undertaken for basic survival. Decline in growth in industrial sector, contracting civil sector, economic recession and the institution of Structural Adjustment Programmes (SAPs) among other factors have promoted the growth of hawking trade. In 2003, it contributed 13 per cent to Kenyas’ GDP and is still growing. The sector is though faced with numerous challenges in its operations such as conflicts and confrontations with the authorities, lack of recognition, eviction, unfavorable policies and regulatory frameworks, pavement use conflicts with pedestrians and formal businesses, lack of services and infrastructure among others. Previous efforts to manage and relocate the hawkers have not been successful as the hawkers have returned back to the streets. This book aims to find-out the nature of hawking trade, identify challenges and opportunities of practicing hawking, to examine policies, participatory and regulatory framework for integrating hawking in the CBD of Nairobi.

The Grand Scribe?s Records V 7 – The Memoirs of Pre–Han China
When and how did the universe begin? Why are we here? Is the apparent 'grand design' of our universe evidence for a benevolent creator who set things in motion? Or does science offer another explanation? In The Grand Design, the most recent scientific thinking about the mysteries of the universe is presented in language marked by both brilliance and simplicity. Model dependent realism, the multiverse, the top-down theory of cosmology, and the unified M-theory - all are revealed here. This is the first major work in nearly a decade by one of the world's greatest thinkers. A succinct, startling and lavishly illustrated guide to discoveries that are altering our understanding and threatening some of our most cherished belief systems, The Grand Design is a book that will inform - and provoke - like no other.
A how-to guide for Java programmers who want to use design patterns when developing real-world enterprise applications This practical book explores the subject of design patterns, or patterns that occur in the design phase of a project's life cycle. With an emphasis on Java for the enterprise, Mark Grand guides Java programmers on how to apply traditional and new patterns when designing a large enterprise application. The author clearly explains how existing patterns work with the new enterprise design patterns and demonstrates through case studies how to use design patterns in the real world. Features include over 50 design patterns, each mapped out by UML, plus an overview of UML 1.4 and how it fits in with the different phases of a project's life cycle.
As more people across the globe move into cities, living space becomes a precious commodity. Designers, architects, and innovative inhabitants seek new ways of creating a home that is just as comfortable as it is functional and attractive. Where does one stow clothing, bicycles, suitcases, or bed linens? Where is the perfect place for the desk, bed, or couch? How does one use less square meters more effectively? And can one family live in a one-room flat? This book explores design concepts and provides solutions to diminutive domiciles.
