It is gratifying to launch the third edition of our book. Its coming to life testi?es about the task it has ful?lled in the service of the com- nity of chemical research and learning. As we noted in the Prefaces to the ?rst and second editions, our book surveys chemistry from the point of view of symmetry. We present many examples from ch- istry as well as from other ?elds to emphasize the unifying nature of the symmetry concept. Our aim has been to provide aesthetic pl- sure in addition to learning experience. In our ?rst Preface we paid tribute to two books in particular from which we learned a great deal; they have in?uenced signi?cantly our approach to the subject matter of our book. They are Weyl’s classic, Symmetry, and Shubnikov and Koptsik’s Symmetry in Science and Art. The structure of our book has not changed. Following the Int- duction (Chapter 1), Chapter 2 presents the simplest symmetries using chemical and non-chemical examples. Molecular geometry is discussed in Chapter 3. The next four chapters present gro- theoretical methods (Chapter 4) and, based on them, discussions of molecular vibrations (Chapter 5), electronic structures (Chapter 6), and chemical reactions (Chapter 7). For the last two chapters we return to a qualitative treatment and introduce space-group sym- tries (Chapter 8), concluding with crystal structures (Chapter 9). For the third edition we have further revised and streamlined our text and renewed the illustrative material.

We have been gratified by the warm reception of our book, by reviewers, colleagues, and students alike. Our interest in the subject matter of this book has not decreased since its first appearance; on the contrary. The first and second editions envelop eight other symmetry-related books in the creation of which we have participated: I. Hargittai (ed.), Symmetry: Unifying Human Understanding, Pergamon Press, New York, 1986. I. Hargittai and B. K. Vainshtein (eds.), Crystal Symmetries. Shubnikov Centennial Papers, Pergamon Press, Oxford, 1988. M. Hargittai and I. Hargittai, Fedezziikf6l a szimmetri6t! (Discover Sym- try, in Hungarian), Tank6nyvkiad6, Budapest, 1989. I. Hargittai (ed.), Symmetry 2: Unifying Human Understanding, Pergamon Press, Oxford, 1989. I. Hargittai (ed.), Quasicrystals, Networks, and Molecules of Fivefold Sym- try, VCH, New York, 1990. I. Hargittai (ed.), Fivefold Symmetry, World Scientific, Singapore, 1992. I. Hargittai and C. A. Pickover (eds.), Spiral Symmetry, World Scientific, Singapore, 1992. I. Hargittai and M. Hargittai, Symmetry: A Unifying Concept, Shelter Publi- tions, Bolinas, California, 1994. We have also pursued our molecular structure research, and some books have appeared related to these activities: vi Preface to the Second Edition I. Hargittai and M. Hargittai (eds.), Stereochemical Applications of Gas-Phase Electron Diffraction, Parts A and B, VCH, New York, 1988. R. Gillespie and I. Hargittai, VSEPR Model of Molecular Geometry, Allyn and Bacon, Boston, 1991. A. Domenicano and I. Hargittai (eds.), Accurate Molecular Structures, Oxford University Press, Oxford, 1992.

A compilation of sixty biographical sketches of influential female scientists, discussing topics like the state of the modern female scientist and the underrepresentation of women at the higher levels of academia.

New York city is a world center of science and the memorabilia presented introduce the reader to a culture of learning and of creating new knowledge, venues of great medicine, and a number of exceptional schools graduating world leaders in science.

André Goodfriend was Deputy Chief of Mission from 2013 to 2015 at the US Embassy in Budapest. In the absence of an ambassador, most of the time he was Chargé d’Affaires. Goodfriend represented his country, and for that matter, liberal democracy, in the early period of the increasingly autocratic Orbán regime. This tenure was distinguished by an unusually high public visibility and broad-based popularity. This book contains the distilled essence of conversations recorded in the fall of 2015 and in the years after his departure. Aside from Goodfriend’s reflections on his personal history, the main focus of the deliberations is on open government: its characteristics, preconditions, benefits, and its relation to modern diplomacy. The mindset of a democracy-rooted diplomat with a working experience in an increasingly autocratic regime lends a particular perspective to the topics discussed. These topics include the fight against corruption, the protection of civil society, crisis prevention, education, economy, international relations, applied humanities, and the use of the social and traditional media to achieve policy goals. This book presents modern, “people-friendly” diplomacy in an era in which public officials are increasingly expected to be transparent and engaged.

Throughout the 1990s and the 2000s, Istvan, Balazs, and Magdolna Hargittai conducted hundreds of interviews with leading scientists in physics, chemistry, materials, and biomedical research. These interviews appeared in a variety of publications, including Chemical Intelligencer, Mathematical Intelligencer, and Chemical Heritage. In four-thousand pages of interviews, the Hargittais had conversations with over a hundred Nobel laureates, along with many other top minds and personalities in various scientific fields. Now, in a single volume, the Hargittais have gathered the best and most notable moments of these interviews, creating a survey of the past, present, and future of science, as told by some of the most influential members of many scientific disciplines. Figures like James D. Watson, Francis Crick, and Glenn T. Seaborg share their thoughts in these pages, in a collection that includes 68 Nobel Laureates. Without exaggeration, their backgrounds come from all over the globe: scientists from the United States, the United Kingdom, Canada, France, Germany, Israel, Russia, Sweden, Switzerland, and Taiwan are featured. These interviews discuss many of the most prominent debates and issues in today's scientific climate. Great Minds is a synthesis of scientific thought, as told by some of the most notable scientists of the twentieth and twenty-first centuries.

This book introduces readers to the fundamentals of oxygen atom transfer reactions. It also gives mechanistic insights into the redox processes occurring through the oxygen atom transfer reactions. It also includes information about catalytic activation of oxygen through enzymes and oxo-metallic complexes. All topics are explored in separate chapters. Key features: - reviews the basic mechanisms in redox processes involving oxo-atom transfer reactions. - presents progress in the biomimetic activation of dioxygen related to the catalytic oxidations by synthetic metal organic complexes. - covers an important class of metal-organic compounds - nickel-oxygen species - generated in catalytic oxidation processes as oxygen atom transfer agents. - explains the mechanistic aspects of the heterogeneous photochemical redox processes via oxo-atom transfer reactions - provides references for further reading It is a reference for both professional scientists in the fields of chemistry, biology and applied sciences, and for graduate and undergraduate students interested in understanding reaction mechanisms involving oxygen.
