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.

Today, the term "natural reserve" is common in Israel. However, this wasn’t the case during the first years of its existence. A majority of the planning authorities did not understand what natural reserves were and why they were required, and the Hebrew language did not yet have a term for them. A small group of nature lovers struggled to preserve nature, leading battels, some of which continue to this day. The results of some of the successful battles can be seen across Israel today – in natural reserves, national parks and fields of wildflowers. The history of these battles is brought forth in this book by Dr. Uzi Paz, one of the pioneers of nature preservation in Israel. He also unfolds the changes formed in the country's landscape, flora and fauna, from ancient times to this day. The book contains a wealth of photographs taken by the author.

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.

In October 2018, results of a randomized controlled trial showed an excess mortality mainly from cancer, among “healthy” people over the age of 70 who took aspirin, in contrast to many clinical studies previously published. This event was another record in the crisis in scientific medicine that has been unfolding before our eyes in recent decades. In this book the author tries to trace the causes of the shocks that afflict the medical knowledge base, and to offer solutions to strengthen and stabilize it. This book includes four parts. The first part discusses aspirin as a test case for development of clinical research. The second part is devoted to a discussion of the seven foundations of modern clinical research while revealing the pros and cons of each and their relative contribution to the pursuit of scientific truth. In the third part, five groundbreaking discoveries are examined. In each of them, the process that led to the discovery is deciphered, emphasizing the findings making clinical research, on the way from bench to bedside, redundant. In the fourth part the author exposes the rules of the competition among scientist, and determines its impact on the conduct of research and its results.

In 2000, the book The Incense Trade Route 2000 was published. Since then, many changes occurred in the terrain, knowledge, research and the geo-political situation, in light of the peace treaties between Israel and other counties in the Middle East. The most prominent researchers of the Incense Trade Route have come together to write a new and updated edition.

This book describes the increasing interactions between wildlife and people in human settlements in Israel and beyond.

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 book describes the natural history, behavior, ecology and conservation of the Nubian ibex. This endangered species is one of the great successes of nature conservation in Israel.

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.

There over 1,300 species of bats in the world, which constitute one-third of the total sum of mammals in Israel. Most people are not aware of them and their fantastic ways of living, because contrary to other mammals, bats do not walk or swim (although they are capable of doing both), but rather fly actively. They are also nocturnal, and unlike most mammals and birds their main sense is not sight but hearing. In order to find their way around, bats omit calls and listen to the echoes they produce in order to navigate. This is also how they find their prey, which is comprised of a variety of animals such as insects, scorpions, fish, frogs, and toads, as well as nectar and fruit. Each species of bats has a special diet and unique behavioural , anatomical and physiological adaptations for this purpose. Bats are beneficial to people by pollinating flowers of many plants, consuming enormous quantities of insects that spread malaria and damage agricultural crops and producing valuable fertilizer-guano. In spite of these benefits, people around the world have created many superstitious beliefs and legends about bats and their behavior. This book describes the biology of bats and their complex relationships with humanity.
