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.

A Ramble in the Hive is an eco-philosophical text that deals with the relationship between humans and honeybees from the dawn of humanity to the present day, interlinking mythology, folklore, literature, art and science from different historical periods. A Ramble in the Hive works as both popular science and philosophy, combining a study of the history of beekeeping and its multitude of inventions, with a philosophical and poetic view of the human encounter with honeybees as reflected in the imagination of our culture. It suggests approaching the hive as an archetype of living mythology that works on our collective imagination. A Ramble in the Hive presents the planetary honeybee crisis as a fascinating window through which to observe wide-ranging ecological issues. How did the honeybee get such a lofty and critical role – holding responsibility for both the future of humanity and the earth? What do the bees tell us in their current state? This book is an attempt to answer these questions.

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.

Dan Perry was born and raised on Mount Carmel. From childhood, encouraged by his father, he often wandered on the mountain, getting to know its surroundings and connecting with its flora and fauna. As an adult, he became involved in the newly formed Nature Conservation Authority - first as a tour guide, and later as part of the Society for the Protection of Nature. In 1965 he started working within the Nature Conservation Authority, established in 1964, as an inspector in the Galilee as part of a collaboration between the Society and the Authority. Immediately after the Six-Day War, he established a magnificent system of nature reserves on the Golan Heights. He ran the Hermon Development Authority which established the Hermon site, and then joined the Authority's management and held a variety of positions. This unique volume includes color photographs.

Atlas of East Galilee Caves is published in a challenging period for the Upper Galilee, with hopes for a swift return to routine in this beautiful and region, bountiful with caves. The Atlas is published following studies and surveys conducted over the past decades. The boundaries of the area defined in the Atlas are the Hula Valley in the east, the border of Lebanon in the north and northwest, the sources of the streams flowing eastward in the west and the Issachar highlands in the south. The Atlas presents the basic data of the caves, and contains a concise multidisciplinary overview of what is known about them from a geological, historical, archaeological and biological point of view. The data is accompanied by plans and illustrations that expand the overall picture of each cave.

Although frequently observed in natural habitats across Israel, the true nature of the "strange growths" (galls) that appear on various plants is not always clear. Insect-induced plant galls are actually the most intimate way in which animals feed on plants. This book reveals to naturalists and scientists one of the most impressive and conspicuous groups among gall-forming insects: aphids that form galls on wild pistachio (Pistacia). The gall serves as an incubator for the aphids, providing them with a rich food supply and shelter from natural enemies and abiotic factors. Several aphid generations develop in galls from spring to fall. During these months, the gall functions as a dynamic and complex multitrophic ecological (mini) system, including pathogens, competitors, parasites, and predators. The first part of the book describes the multi-disciplinary information on the biology and ecology of the aphids and gall system from molecular, anatomical, physiological, biochemical, behavioral, biogeographic, and evolutionary points of view. The second part of the book is in fact an informative and photographic guide to all the aphid-induced galls on wild pistachios in Israel.

In the second half of the twentieth century, the medical community adopted the scientific method as a basis for practice. It seemed that after thousands of years the way was paved for a regulated process: from the laboratory through the clinical trial to the patient's bed. But it soon became clear that the road is neither straight nor continuous. Clinical research only offers unequivocal answers in a few cases. The balance between benefit and risk does not end with a statistical calculation; A significant part of the consideration of the factors that determine the change of medical practice is based on values, worldview and interests. Many factors are involved in the path leading from the laboratory to the patient: scientists, doctors, pharmaceutical and technology companies, politicians, regulators, and at the end of the path stand the patients themselves. Each of these factors uses the means at its disposal to influence the final result - the diagnosis, treatment and follow-up of the patient. The path of progress from the laboratory to the patient is also not continuous: sometimes the intervals between steps are large, sometimes sudden jumps occur after a prolonged period of slowing down and even stopping. Scientific and clinical research depends on the initiative, skills and determination of the researchers, and not a little on coincidences and has no fixed timetables. This book is dedicated to revealing the evolution of medical practice, to identifying fundamental changes in practice and to describing the winding way in which they were accepted and assimilated into the body of medical knowledge and the mutual relationship between the doctor and the patient.

The migration of birds is a fascinating phenomenon that has aroused curiosity since ancient times. This book brings to the interested reader the latest knowledge collected on this phenomenon by many researchers - scientists and enthusiasts, in Israel and around the world, and also presents the importance of the Land of Israel as a major traffic route for birds that migrate from Europe and Asia to Africa and back again. Recognizing this importance also has implications for preserving nature in the country.

The spread of the Assyrian Empire over the entire Fertile Crescent in the second half of the 8th century BC introduced various forms of cooperation between the neighboring nomadic Arabs and the imperial authorities. The geographical conditions and resultant lifestyle of the Arabs facilitated a mutual dependence and delicate equilibrium between themselves and the Assyrian rulers, eager to capitalize on their unprecedented regional might. Henceforth, the Arabs appear as an organic component of the Fertile Crescent history rather than mere desert raiders.
