Over the past two decades, advanced technologies and space missions have completely transformed our understanding of potential life beyond Earth. The resulting field, astrobiology, has become a multidisciplinary scientific discipline, encompassing many of the natural sciences and having implications for many areas of research. This book presents an introduction and overview of astrobiology. It deals with a wide range of fields, from the search for signs of life on planets in our solar system, to the discovery of exoplanets in distant solar systems and assessing the potential for life there. The book is based on the course of the same name that the author taught for more than two decades at the Hebrew University, and the course recorded on YouTube in the Cornerstones program , which has accumulated tens of thousands of views. The book is accessible not only to students of natural sciences, but to any reader who wants to learn about and understand the fascinating possibilities of life on other worlds.

This course book features a systematic method of presenting the foundations of modern algebra, focusing on three main theories: groups, rings, and fields. It contains numerous exercises.

Hinneh – a new and revised 3-volume edition A Biblical Hebrew Textbook unlike Any Other Introduction Hinneh balances two major demands of an introductory language program: the presentation of the most frequently occurring lexical and grammatical examples, and the sequencing of the material in a way that allows for easier teaching and learning. · Enables a rigorous yet non-intimidating learning experience for students of different levels. · Provides the skills and tools necessary to allow students to independently access most biblical texts early on. · Gradually builds students’ knowledge through wide exposure to a large number of biblical verses, prose, and poetry, accompanied by translation exercises. · Offers many styles and different possible interpretations of various biblical texts so that students can independently and critically examine and evaluate biblical translations. · Employs learning methods informed by second language pedagogy and related fields (e.g. order of presentation determined by both frequency and “learnability,” “Color by root groups” to internalize the complex verb system, etc.). · A textbook and workbook for both the academic and non-academic classroom, as well as for the independent learner. Rahel Halabe is a designer, developer, and instructor of both Biblical and Modern Hebrew curricula with more than 20 years of experience.

This book is intended for a varied audience - undergraduates in the exact, natural sciences as well as those interested in basic Quantum mechanics. In addition, certain chapters are intended for graduate students who may wish to incorporate the material presented in this book into their research. Together, the volumes contain in access of a hundred solved problems in varying degrees of difficulty, which assist in understanding Quantum Mechanics and its applications.

The fourth book in the series of Understanding Physics describes three important topics. Fluids – which include both liquids and gases – play a central role in our daily lives. We breathe and drink them, and a rather vital fluid circulates in the human cardiovascular system. The Earth's oceans and atmosphere consist of fluids. Waves – deals with many phenomena like sound waves that carry our messages from our vocal cords to the ears of our friends. Electromagnetic waves carried through optic fibers or through the atmosphere, allow communication with satellites. The book presents: oscillations and harmonic motions, mechanical waves and sound waves. Thermodynamics – heat theory development is one of humankind's most profound intellectual achievements. Understanding thermodynamic principles was fundamental for steam engines that powered the industrial revolution. The book deals with the first law of the thermodynamics, the kinetic theory of gases and the second law of thermodynamics. As in former volumes of Understanding Physics – this book contains clear explanations from basics phenomena to complicated models. It allows readers to examine their understanding by reading exercises and examples. Many figures, diagrams and photos facilitate discovery with this book and convert the experience of learning into a vivid and plausible encounter. The book is based on Fundamental of Physics by David Halliday, Robert Resnick and Jearl Walker.

Magnetism and Optics is a second book in the series of three. This book is built on the foundations of the 6th Edition of Halliday, Resnick, and Walker’s Fundamentals of Physics. One of primary goals of this book is to help students make sense of the physics they are learning. We cannot achieve this goal if students see physics as a set of disconnected mathematical equations that each apply only to a small number of specific situations. We stress conceptual and qualitative understanding and continually make connections between mathematical equations and conceptual ideas. We also try to build on ideas that students can be expected to already understand, based on the resources they bring from everyday experiences. This text is designed to work with learning strategies such as microcomputer-based labs and interactive lectures that are increasingly being used in physics instruction.

This is not an updated edition! Because of the many topics that appear in this book, it was decided to split the book into two parts, make corrections and more. You can now purchase the Second Edition: Understanding physics-mechanics I (earlier chapters from the first edition + corrections + chapter summaries) Understanding physics mechanics II (later chapters from the first edition + new chapter + corrections + chapter summaries).

The use of narratives in social science research has increased enormously during recent decades, and has generated theoretical developments and fascinating empirical insights that have crystallized into an overall "narrative turn". Written and oral stories, diaries and interviews, serve as central channels in narrative research, supplying a multilayered glimpse into personal identities as well as into the social and cultural realities in which people live and develop. In the chapters of this book, Israeli researchers from various disciplines tackle theoretical, methodological, and applicable issues associated with narrative research. Diverse aspects are discussed: What is a narrative and why is it perceived as a central channel for our experiences and identities and for the meanings we ascribe to ourselves and to our world? What is "narrative thinking"? Is narrative research a paradigm? What distinguishes narrative research from other types of qualitative research? How are narrative research and feminism connected? The chapters of this book also deal with the complex relationship between narrative researchers and their research participants - the narrators - and with issues associated with the interpretation of narratives and the rich world of "narratives in action" in a variety of life domains.
