In 1905, Albert Einstein astounded the scientific world when he proposed a theory that would become known as the special theory of relativity. Einstein's theory revolutionized the fundamental concepts of time and space, demonstrated the equivalence between mass and energy, and completely changed the face of modern physics. Despite its enormous importance, the theory of special relativity has remained largely unknown to the public interested in the scientific revolutions of the twentieth century. This book presents the theory of special relativity in a way that any student of the natural sciences can understand the theory itself, the crisis that led to its emergence, and its dramatic impact on the world of science. The book takes the reader on a fascinating, yet entertaining, journey of discovery and understanding of the theory of special relativity.

Einstein’s revolution traces back to his key papers of 1905 in which he questioned the classical understanding of our concepts of space, time, matter, gravitation, and radiation, shaking the foundations of classical physics. These papers challenged the idea of light as a wave, gave striking proof for the existence of atoms, led to a new understanding of space and time, which came to be known as the “special theory of relativity,” and identified mass as a form of energy. Ten years later, Einstein completed his relativity revolution with his masterpiece, the general theory of relativity, which became the source of modern cosmology. Albert Einstein : Creator of a Worldview deals with these developments, with the ideas which led to them and with their consequences. It also describes briefly Einstein’s activity outside the world of physics and his reaction to major issues on the agenda of mankind in his time.

In the 1940s, Erwin Schrödinger attempted to tackle the eternal question "What is Life?" from the perspective of the "naïve physicist." The result is this short book, which has influenced generations of scientists, sparked much controversy and become a classic. What Is Life? appears in Hebrew for the first time, accompanied by an epilogue by Prof. Avshalom Elitzur, who demonstrates to what extent Schrödinger's insights are relevant eighty years after the first publication of the essay.

If a large rock had collapsed in a desert or a tree had fallen in the heart of a distant forest several hundred miles away from living beings, would it have made a sound upon its fall? Different people will give different answers to this ancient question. Objectively, some will say that a sound would have been heard because sound does not exist only in the mind of the listener. Subjectively, some would say that a sound requires someone to listen to it. What is correct? Is this complex answer related to the essence of sound? It's All in the Sound investigates the phenomenon of sound and tries to understand it and answer, among other things, the above questions. It was written to meet the needs of students and teachers, with a desire to update the teaching of physics and fill the shortage of textbooks in this field, which is associated with teaching the subject of sound waves. The gradual development of the concept of sound is discussed in the book by building structured experimental illustrations, as well as mathematical expressions describing this miraculous phenomenon. The illustrations were chosen so that a curious reader could repeat most of the experiments in a home environment without the need for special laboratory equipment. Even for readers unfamiliar with the basics of physical mathematics that describe sound, this book may provide a unique experience and open up a new window to understanding physics.

The book describes the Copernican Revolution, initiated by the publication of On the Revolution of the Heavenly Spheres by Copernicus until it was accepted by the Scientific Community. The book follows the dramatic turns of the plot of the struggle for scientific truth, along with the conflict between the church and Galileo. Finally, the book brings the modern proofs for the Copernican model, including the very recent discoveries of extra-solar planets.

The book takes the reader on a journey of discovery ranging from the planets of our solar system to stars and distant solar systems in the Milky Way, our home galaxy, and beyond to the ends of the universe. It proposes a reader-friendly introduction to astrophysics and the physics of stars and planets, accompanied by over one hundred illustrations. The book explains concepts, distances and phenomena from other worlds, very different from our everyday experience. Throughout its journey through the universe the book introduces the science of astrobiology: the search for biological life in space. It also accompanies the course "Astrobiology and Life in the Universe" presented by the author and recorded for the benefit of the public in the "Cornerstones" program of the Hebrew University. The book deals with topics that have received widespread media coverage in recent years, such as NASA's research missions to Mars and their Kepler and James Web space telescopes. While the Kepler mission led in 2010-2015 to a breakthrough in discovering numerous worlds suitable for life outside the Solar System, James Web, whose launch is expected in 2021, will provide to humanity for the first time the ability to detect signs of life in these 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.
