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 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.

Modern Investment Theory is the only book published in Hebrew on this central topic for students and practitioners of business and economy. The book opens with a review of the investment environment and the structure and institutions of the Israeli capital market, as well as a description of the assets traded in the equity, debt, and derivative markets. Since Israel is a small economy, its interactions with global financial markets is highlighted. The core concepts are presented by order of their evolution and contribution to the field: from rational and behavioral decision-making in states of risk, to Portfolio Theory, the CAPM, and advanced theoretical and empirical models, including five-factor models. Three chapters are devoted to fixed income pricing and risk, and two chapters address derivative assets and their pricing. Some of the chapters introduce for the first time in Hebrew financial crises and their impact on the real economy and on society, private capital, behavioral finance, and international finance. Many of the concepts of modern investment theory were developed by prominent researchers; some won Nobel or other prestigious prizes. To sixteen of these outstanding researchers, seven of whom are Israeli, I devote special boxes entitled "Figures from the Hall of Fame," highlighting their contribution to the field. Pedagogically, the book follows the American model where each chapter is accompanied by a Powerpoint presentation file, the chapter is briefly summarized, has a list of key terms, and between twenty to forty questions. Teachers can access all chapter solutions.
