In his autobiography, Abraham Halevi Fraenkel describes growing up as an Orthodox Jew in Germany and his development as a mathematician at the beginning of the twentieth century. In his memoir, originally published in German in 1967, Fraenkel painted a unique picture of the complexity of Jewish life in Germany with special emphasis on the developments in the Orthodox community. He described the world of mathematics in Germany in the first half of the twentieth century, in the context of the great mathematicians he met, many of whom were Jews or had Jewish roots. In his personal life, Fraenkel merged the worlds of orthodox Judaism, liberal Zionism and mathematics, in a period of global and national upheavals, which included the two World Wars and the establishment of the State of Israel. The last chapter of the book, which describes his extensive public activity in Israel from the 1930s until his death in 1965, was written by Prof. Jiska Cohen-Mansfield. Introductions were added by Prof. Yehoshua Bar-Hillel and Prof. Menachem Magidor, the former president of the Hebrew University.

Graph Theory is, as far as we know, the first to be written by this approach. Its initial purpose was to serve as a high-school textbook for students learning graph theory in a systematic and orderly manner. Until the publication of this book, graph theory was only taught in academic institutions. The book soon began to serve as a reference book and even as a textbook in colleges and academic institutes for lecturers and students of mathematics and computer science. The book in its current format includes five chapters: 1. Definitions, Examples and Basic Concepts; 2. Paths and Circuits in Graphs; 3. Trees 4. Networks 5. Games, Puzzles and Graph Theory. The intention is to release it in a new and expanded edition.

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.

Elementary School Mathematics is written for elementary school teachers as well as parents who wish to be involved in their childrens first steps in mathematical education. The reading of this book will benefit educators - whether at home or at school - by consolidating their content knowledge, while exposing them to both complexity and beauty of elementary mathematics.

In recent years, the number of Israelis interested in South Korea, its culture and language is growing . Among these, are academics, the Korean Wave fans (includes TV series, movies and pop music), and executives who have Korean partners and wish to familiarize themselves with Korean culture . " Korean for Beginners " is the first book of its kind in Hebrew, which will serve anyone wishing to take their first steps into the world of Korean language . The book is intended for students in classrooms as part of a curriculum or as a supplementary workbook, or for individuals who wish to explore the Korean language in self-study . The book opens with teaching the Korean alphabet and introduces the learner to essential topics that they will encounter while learning the language. The book presents the learner with grammar rules and vocabulary components in an organized, step-by-step format that will allow learners to have basic conversations in Korean.

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.
