This book, in its first part, contains units of conceptual history of several topics of physics based on the research in physics education and research based articles with regard to several topics involved in teaching science in general and physics in particular. The second part of the book includes the framework used, the approach considering science knowledge as a special type of culture – discipline-culture. Within this approach, scientific knowledge is considered as comprised of a few inclusive fundamental theories each hierarchically structured in a triadic pattern: nucleus-body-periphery. While nucleus incorporates the basic principles and body comprises their implementations in the variety of laws, models, and experiments, periphery includes concepts at odds to the nucleus. This structure introduces knowledge in its conceptual variation thus converting disciplinary knowledge to cultural-disciplinary one. The approach draws on history and philosophy of science (HPS) necessary for meaningful learning of science. It is exemplified in several aspects regarding teaching physics, presenting history in classes, considering the special nature of science, and using artistic images in regular teaching. The revealed conceptual debate around the chosen topics clarifies the subject matter for school students and teachers encouraging construction of Cultural Content Knowledge. Often missed in teachers' preparation and common curriculum it helps genuine understanding of science thus providing remedy of students' misconceptions reported in educational research.

One day, a young girl astride a twin-tailed dragon will destroy the monarchy and change the world for ever ... Kira and Elspeth have already broken FIRST LAW many times over. Now outlawed and running for their lives they are determined to stand amongst the men and fight the unjust FIRST LAW that binds the kingdom. But cruel Lord Dorcon still stands in their way and the heat of his chase is stronger than ever. Strong and determined, Kira has done all that she can to protect and shield her younger sister. But now it's time for Elspeth to grow up. When Paradon's muddled magic sends them travelling through time to different eras, new challenges and terrifying threats await the separated sisters. Especially to Elspeth, left all alone to navigate a past world long before the rule of King Ardon and FIRST LAW. And all the while in a strange, alien world of the future, Kira must find a way to get back to Elspeth and reunite her family once again. A prophecy to fulfil. A cruel monarchy to upend. The battle continues ...

The theoretical physicist shares his latest thoughts on the nature of space and time in this anthology of selections from Princeton University Press. Along with eminent colleagues, Hawking extends theoretical frontiers by speculating on the big questions of modern cosmology.

Thermodynamics is fundamental to university and college curricula in chemistry, physics, engineering and many life sciences around the world. It is also notoriously difficult for students to understand, learn and apply. What makes this book different, and special, is the clarity of the text. The writing style is fluid, natural and lucid, and everything is explained in a logical and transparent manner. Thermodynamics is a deep, and important, branch of science, and this book does not make it "easy". But it does make it intelligible. This book introduces a new, 'Fourth Law' of Thermodynamics' based on the notion of Gibbs free energy, which underpins almost every application of thermodynamics and which the authors claim is worthy of recognition as a 'law'. The last four chapters bring thermodynamics into the twenty-first century, dealing with bioenergetics (how living systems capture and use free energy), macromolecule assembly (how proteins fold), and macromolecular aggregation (how, for example, virus capsids assemble). This is of great current relevance to students of biochemistry, biochemical engineering and pharmacy, and is covered in very few other texts on thermodynamics. The book also contains many novel and effective examples, such as the explanation of why friction is irreversible, the proof of the depression of the freezing point, and the explanation of the biochemical standard state.

This introductory textbook provides a synthetic overview of the laws and formal aspects of thermodynamics and was designed for undergraduate students in physics, and in the physical sciences. Language and notation have been kept as simple as possible throughout the text. While this is a self-contained text on thermodynamics (i.e. focused on macroscopic physics), emphasis is placed on the microscopic underlying model to facilitate the understanding of key concepts such as entropy, and motivate a future course on statistical physics. This book will equip the reader with an understanding of the scope of this discipline and of its applications to a variety of physical systems Throughout the text readers are continuously challenged with conceptual questions that prompt reflection and facilitate the understanding of subtle issues. Each chapter ends by presenting worked problems to support and motivate self-study, in addition to a series of proposed exercises whose solutions are available as supplementary material. Features Pedagogically designed, including illustrations, keyword definitions, highlights, summaries of key ideas and concepts, and boxes with additional topics that complement the materials presented in the main text. Presents active reading strategies, such as conceptual problems, discussion questions, worked examples with comments, end of chapter problems, and further reading to stimulate engagement with the text. Guides the reader with ease through a difficult subject by providing extra help whenever needed to overcome the more demanding technical and conceptual aspects. Solutions Manual available upon qualifying course adoption.
