Qu’est-ce que la psychologie ? Que sont les psychologues et que font-ils ? C’est à ces questions que cet ouvrage s’efforce de répondre. Et tout d’abord, faut-il parler de la psychologie ou des psychologies ? Définir LA psychologie n’est pas chose simple. La définition la plus simple et la plus évidente consiste à dire qu’il s’agit de l’étude scientifique des processus psychiques. Mais dès ce moment, des désaccords surviennent. Un psychologue comportementaliste pur et dur nous rétorque : « Le psychisme est une illusion, seul compte le comportement. » Un psychanalyste nous interpelle : « Quand vous utilisez l’expression processus psychiques, parlez-vous des processus conscients ou inconscients ; car au fond, seuls ces derniers sont essentiels », etc.

The landscape of history: how historians map the past

What is history and why should we study it? Is there such a thing as historical truth? Is history a science? One of the most accomplished historians at work today, John Lewis Gaddis, answers these and other questions in this short, witty, and humane book. The Landscape of History provides asearching look at the historian's craft, as well as a strong argument for why a historical consciousness should matter to us today.Gaddis points out that while the historical method is more sophisticated than most historians realize, it doesn't require unintelligible prose to explain. Like cartographers mapping landscapes, historians represent what they can never replicate. In doing so, they combine the techniques ofartists, geologists, paleontologists, and evolutionary biologists. Their approaches parallel, in intriguing ways, the new sciences of chaos, complexity, and criticality. They don't much resemble what happens in the social sciences, where the pursuit of independent variables functioning with staticsystems seems increasingly divorced from the world as we know it. So who's really being scientific and who isn't? This question too is one Gaddis explores, in ways that are certain to spark interdisciplinary controversy.Written in the tradition of Marc Bloch and E.H. Carr, The Landscape of History is at once an engaging introduction to the historical method for beginners, a powerful reaffirmation of it for practitioners, a startling challenge to social scientists, and an effective skewering of post-modernistclaims that we can't know anything at all about the past. It will be essential reading for anyone who reads, writes, teaches, or cares about history.

What Science is and How it Works

How does a scientist go about solving problems? How do scientific discoveries happen? Why are cold fusion and parapsychology different from mainstream science? What is a scientific worldview? In this lively and wide-ranging book, Gregory Derry talks about these and other questions as he introduces the reader to the process of scientific thinking. From the discovery of X rays and semiconductors to the argument for continental drift to the invention of the smallpox vaccine, scientific work has proceeded through honest observation, critical reasoning, and sometimes just plain luck. Derry starts out with historical examples, leading readers through the events, experiments, blind alleys, and thoughts of scientists in the midst of discovery and invention. Readers at all levels will come away with an enriched appreciation of how science operates and how it connects with our daily lives. An especially valuable feature of this book is the actual demonstration of scientific reasoning. Derry shows how scientists use a small number of powerful yet simple methods--symmetry, scaling, linearity, and feedback, for example--to construct realistic models that describe a number of diverse real-life problems, such as drug uptake in the body, the inner workings of atoms, and the laws of heredity. Science involves a particular way of thinking about the world, and Derry shows the reader that a scientific viewpoint can benefit most personal philosophies and fields of study. With an eye to both th

Analysis of variance and covariance: How to choose and construct models for the life sciences

Analysis of variance (ANOVA) is a core technique for analysing data in the Life Sciences. This reference book bridges the gap between statistical theory and practical data analysis by presenting a comprehensive set of tables for all standard models of analysis of variance and covariance with up to three treatment factors. The book will serve as a tool to help post-graduates and professionals define their hypotheses, design appropriate experiments, translate them into a statistical model, validate the output from statistics packages and verify results. The systematic layout makes it easy for readers to identify which types of model best fit the themes they are investigating, and to evaluate the strengths and weaknesses of alternative experimental designs. In addition, a concise introduction to the principles of analysis of variance and covariance is provided, alongside worked examples illustrating issues and decisions faced by analysts

The definitive guide to how computers do math: featuring the virtual DIY calculator

The Basics of Computer Arithmetic Made Enjoyable and Accessible-with a Special Program Included for Hands-on Learning "The combination of this book and its associated virtual computer is fantastic! Experience over the last fifty years has shown me that there's only one way to truly understand how computers work; and that is to learn one computer and its instruction set-no matter how simple or primitive-from the ground up. Once you fully comprehend how that simple computer functions, you can easily extrapolate to more complex machines." -Fred Hudson, retired engineer/scientist "This book-along with the virtual DIY Calculator-is an incredibly useful teaching and learning tool. The interesting trivia nuggets keep you turning the pages to see what's next. Students will have so much fun reading the text and performing the labs that they won't even realize they are learning." -Michael Haghighi, Chairperson of the Business and Computer Information Systems Division, Calhoun Community College, Alabama "At last, a book that presents an innovative approach to the teaching of computer architecture. Written with authority and verve, witty, superbly illustrated, and enhanced with many laboratory exercises, this book is a must for students and teachers alike." -Dr. Albert Koelmans, Lecturer in Computer Engineering, University of Newcastle upon Tyne, UK, and the 2003 recipient of the EASIT-Eng. Gold Award for Innovative Teaching in Computer Engineering Packed with nuggets of information and tidbits of trivia, How Computers Do Math provides an incredibly fun and interesting introduction to the way in which computers perform their magic in general and math in particular. The accompanying CD-ROM contains a virtual computer/calculator called the DIY Calculator, and the book's step-by-step interactive laboratories guide you in the creation of a simple program to run on your DIY Calculator. How Computers Do Math can be enjoyed by non-technical individuals; students of computer science, electronics engineering, and mathematics; and even practicing engineers.

A Summer in Amber

A young physicist is dispatched to a remote Scottish estate to secretly decipher the fragments of a manuscript that may hold the key to restoring the solar storm ravaged 21st century. Once there he finds whispers of a reincarnated wizard, strange forces linked to an eerie laboratory said to be a gate to the Otherworld, and a girl. A classic science fiction novel of adventure and romance. The story is set thirty-six years after the first of a series of powerful solar storms destroys the world's electrical grid – shorting out computers, and making radio, TV and mobile phones impossible. Within hours the world was thrust back into the 19th century. Those who survived the ensuing chaos gradually adopted to this new reality. This story takes place in an England and Scotland that have adopted to this new world using an eclectic mix of old and new technology. Steam engines pull carriages over lines once used by high speed trains. Electricity is generated locally using solar panels and windmills. The streets are filled with bicycles dodging horse drawn drays and pedestrians dressed like Victorians to protect their skin from the greatly increased ultraviolet light reaching the ground due to the solar storms' disruption of the earth's upper atmosphere.

الضمير Conscience لغةً هو «المستور. أُطلق على العقل لكونه مستوراً عن الحواس، وضمير الشيء: عينه». أما في مجال الأخلاق، فإن العربَ أشاروا إلى مفهوم الضمير أو الوجدان بأسماء مختلفة، لعل أقربها إلى المفهوم الحديث هو معنى المروءة. فالمروءة مراعاة الأحوال التي تكون على أفضلها حتى لايظهر منها القبيح عن قصد، ولايتوجه إليها ذمّ باستحقاق.

Le meunier d d'Angibault pdf

Ce roman est, comme tant d’autres, le résultat d’une promenade, d’une rencontre, d’un jour de loisir, d’une heure de far niente. Tous ceux qui ont écrit, bien ou mal, des ouvrages d’imagination ou même de science, savent que la vision des choses intellectuelles part souvent de celle des choses matérielles. La pomme qui tombe de l’arbre fait découvrir à Newton une des grandes lois de l’univers. À plus forte raison le plan d’un roman peut-il naître de la rencontre d’un fait ou d’un objet quelconque. Dans les œuvres du génie scientifique, c’est la réflexion qui tire du fait même la raison des choses. Dans les plus humbles fantaisies de l’art, c’est la rêverie qui habille et complète ce fait isolé. La richesse ou la pauvreté de l’œuvre n’y fait rien. Le procédé de l’esprit est le même pour tous.

A Brief History of Time

A landmark volume in science writing by one of the great minds of our time, Stephen Hawking’s book explores such profound questions as: How did the universe begin—and what made its start possible? Does time always flow forward? Is the universe unending—or are there boundaries? Are there other dimensions in space? What will happen when it all ends? Told in language we all can understand, A Brief History of Time plunges into the exotic realms of black holes and quarks, of antimatter and “arrows of time,” of the big bang and a bigger God—where the possibilities are wondrous and unexpected. With exciting images and profound imagination, Stephen Hawking brings us closer to the ultimate secrets at the very heart of creation.
