Despite many decades of research, we seem to linger in a state of confusion regarding what leadership is and if or how it might be cultivated. The book offers a new perspective on leadership, whereby what defines leadership is not one’s position or successful conduct but action of a certain kind. More specifically, leadership is about realizing the human potential to think, create or act outside the boundaries of what is known and safe in order to serve the greater good. What distinguishes “acts of leadership” is that they take place in a sphere of ambiguity and uncertainty. As such, acts of leadership are essentially risky, bold and adventurous. Obstacles and opponents are to be expected and no measure of success can be guaranteed. By placing leadership in its unique sphere of action, we realize that widely accepted prescriptions for rational or sensible conduct do not apply and that relying on them may shut us down before we even begin. We further appreciate that such acts exemplify “action” in its deepest sense: what we choose to do as free individuals in an uncertain universe, and how we do it, is a self-defining act; it makes us who we are.

The essay presents the lost archive of the Jewish author Zalman Shneour (Shklov 1887 – New York 1950). It was found in May 2018 at Calle Eraso 21 in Madrid – the city through which he had passed in the summer of 1941. Four carton boxes survived in the apartment of his late daughter, Renee Rebecca Shneour, who fled to New York together with her father but returned to live in Madrid in her adulthood. The essay offers a reading of Shneour's correspondences with three women - his mother in Shklov, his friend and lover in Berlin, and his daughter.

We are pleased to present our readers with this double issue of Massorot , volume 21–22, published by the Center for Jewish Languages and Literatures in collaboration with the Jewish Oral Traditions Research Center. The volume contains eleven articles which testify to the varied interests of contemporary scholars in the field of Jewish languages and the Hebrew traditions of the diverse communities of the Jewish People. Five of the articles concern themselves with Bible translations in Jewish languages, four of these in varieties of Judeo-Arabic: Moshe Bar-Asher discusses the conservative features of the Sharḥ (Judeo-Arabic calque translations transmitted orally) in the Maghreb. Shay Matsa deals with the last Judeo-Arabic Bible translation from Aleppo and its author. Ibrahim Bassal scrutinizes the interplay of elements from the Tafsīr of Saadiah Gaon and the Syriac Bible tradition in a Christian Arabic Bible translation. Zahi Abbas discusses the distinctive features of Saadiah Gaon’s Judeo-Arabic Bible translation. Yaffa Israeli analyzes translations of the Book of Jonah in three different regional dialects of Jewish Neo-Aramaic, from Urmi, Saqqiz and Rawanduz. Another two articles are concerned with other aspects of Judeo-Arabic in North Africa: Paul B. Fenton discusses three Judeo-Arabic historical dirges, two from the Tafilalt region and one from Algiers. Mor Daniel analyzes the forms of the plural used in the Judeo-Arabic of newspapers published in Tunis at the end of the nineteenth and beginning of the twentieth century. Two articles in the volume deal with Jewish Romance languages: Ora (Rodrigue) Schwarzwald offers the fruit of her research into the Passover Haggadah published in Sofia in Cyrillic letters. Michael Ryzhik focuses on the linguistic features of two Judeo-Italian dramas in Latin letters. Two articles in the volume are concerned with the Hebrew language traditions of different Jewish communities: Mor Shemesh analyzes the whole plural forms of segholate nouns in the reading of the Mishnah according to the late Ashkenazi tradition. Adam Bin-Nun discusses the link between the Yemenite version of the Torah text and that of Maimonides.

The Jewish Haskalah movement heralded a profound, unprecedented cultural-spiritual revolution in the Jewish world. Beginning in the German lands in the second half of the eighteenth century and subsequently spreading to central Europe, it called for reconstituting traditional Jewish society in line with maskilic values. This volume spotlights the early-nineteenth-century Galician Haskalah. Although a backwater annexed to the Austrian Empire from Poland but two generations earlier, Galicia’s impressive gallery of outstanding individuals and literary activity has granted the Galician Haskalah its place as one of the most productive, influential centers of the Haskalah movement. This collection of articles is based on lectures delivered at the "Revealers of Secrets—200 Years of Galician Haskalah" conference. Held in Jerusalem in 2013, this fifth annual conference for the study of the Haskalah movement aimed to submit the Galician Haskalah to renewed scholarly examination. Organized in five sections, the volume’s twenty-three essays by outstanding scholars portray the variegated aspects of this movement, which ranged from attempts to preserve Jewish identity by nurturing modern Jewish culture in Hebrew to radical attempts to reform traditional Jewish society.

In the current book two of the most prolific authors in the area of Medieval Judeo-Arabic and poetic Hebrew Medieval texts go back to its basic theses on the relations between Hebrew literature and its parallel Arabic and Judeo-Arabic texts. By re-establishing an up-to-date picture they are attacking the field of encounters from new and different angles.

The starting point for any study of the Bible is the text of the Masora, as designed by the Masoretes. The ancient manuscripts of the Hebrew Bible contain thousands of Masora comments of two types: Masora Magna and Masora Prava. This book presents the way in which the Masoretic comments preserve the Masoretic Text of the Bible throughout generations and all over the world, providing comprehensive information in a short and efficient manner. The book describes the important manuscripts of the Hebrew Bible, and the methods of the Masora in determining the biblical spelling and designing the forms of the parshiot and the biblical Songs. The effectiveness of Masoretic mechanisms and their degree of success in preserving the text is examined. A special explanation is offered for the phenomenon of qere and ketiv . The book discusses the place of the Masoretic text in the history of the Bible, the differences between the Babylonian Masora and that of Tiberias, the special status of the Aleppo Codex and the mystery surrounding it. Special attention is given to the comparison between the Aleppo Codex and the Leningrad Codex (B 19a). In addition, the book discusses the relationship between the Masora and other tangential domains: the grammar of the Hebrew language, the interpretation of the Bible, and the Halakha. The appendix to the book contains a description of books and computer software that are tools for researching the Masora. The book is based on the author's research and the research of the great scholars of the Masora in recent generations. It is a necessary tool for anyone interested in the text of the Bible and its crystallization.

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.
