Solar Energy: The Physics and Engineering of Photovoltaic Conversion, Technologies and Systems

This book uniquely covers both the physics of photovoltaic (PV) cells and the design of PV systems for real-life applications. - Fundamental principles of semiconductor solar cells. - PV technology: crystalline silicon solar cells; thin-film cells; PV modules; third-generation concepts. - PV systems, from simple stand-alone, to complex systems connected to the grid; components; design; deployment; performance. The book is an invaluable reference for researchers, industrial engineers and designers working in solar energy generation. The book is also ideal for university and third-level physics or engineering courses on solar photovoltaics, with exercises to check students' understanding and reinforce learning. It is the perfect companion to the Massive Open Online Course (MOOC) on Solar Energy (DelftX, ET.3034TU) presented by co-author Arno Smets. The course is available in English on the nonprofit open source edX.org platform, and in Arabic on edraak.org. Over 100,000 students have already registered for these MOOCs.

Mathematics for the Physical Sciences

Introduction to and use of complex analysis and algebraic techniques to understand the solution of boundary value problems. Physics examples serve to introduce the fundamental partial differential equations and "special functions" of mathematical physics. A thorough analysis of Green's functions leads to a discussion of integral equations. Supplementary topics include dispersion relations and rational function approximation.

The Self Illusion: Why There is No 'You' Inside Your Head (Extract)

This is an extended extract from The Self Illusion: Why There is No 'You' Inside Your Head, available 19 April 2012.

Most of us believe that we possess a self - an internal individual who resides inside our bodies, making decisions, authoring actions and possessing free will. The feeling that a single, unified, enduring self inhabits the body - the 'me' inside me - is compelling and inescapable. This is how we interact as a social animal and judge each other's actions and deeds. But that sovereignty of the self is increasingly under threat from science as our understanding of the brain advances. Rather than a single entity, the self is really a constellation of mechanisms and experiences that create the illusion of the internal you.

We only emerge as a product of those around us as part of the different storylines we inhabit from the cot to the grave. It is an every changing character, created by the brain to provide a coherent interface between the multitude of internal processes and the external world demands that require different selves.
