This guidebook introduces the reader to the visible memorabilia of science and scientists in Budapest - statues, busts, plaques, buildings, and other artefacts. According to the Hungarian-American Nobel laureate Albert Szent-Györgyi, this metropolis at the crossroads of Europe has a special atmosphere of respect for science. It has been the venue of numerous scientific achievements and the cradle, literally, of many individuals who in Hungary, and even morebeyond its borders, became world-renowned contributors to science and culture.Six of the eight chapters of the book cover the Hungarian Nobel laureates, the Hungarian Academy of Sciences, the university, the medical school, agricultural sciences, and technology and engineering. One chapter is about selected secondary schools from which seven Nobel laureates (Szent-Györgyi, de Hevesy, Wigner, Gabor, Harsanyi, Olah, and Kertész) and the five "Martians of Science" (von Kármán, Szilard, Wigner, von Neumann, and Teller) had graduated. The concludingchapter is devoted to scientist martyrs of the Holocaust.A special feature in surveying Hungarian science is the contributions of scientists that left their homeland before their careers blossomed and made their seminal discoveries elsewhere, especially in Great Britain and the United States. The book covers the memorabilia referring to both émigré scientists and those that remained in Hungary.The discussion is informative and entertaining. The coverage is based on the visible memorabilia, which are not necessarily proportional with achievements. Therefore, there is a caveat that one could not compile a history of science relying solely on the presence of the memorabilia.

This book introduces the reader to the visible memorabilia of science and scientists in all the five boroughs of New York City - statues, busts, plaques, buildings, and other artifacts. In addition, it extends to some scientists and institutions currently operating in the city. New York has been known as a world center of commerce, finance, communications, transportation, and culture, but it also is a world center in science. The city is home to renowned universitiesand research laboratories, a museum of natural history and other museums related to science, a science academy, historical societies, botanical gardens and zoos, libraries, and a Hall of Science as well as a large number of world-renowned scientists. The book pays special attention to the role ofthis city in welcoming persecuted scientists and letting African-American and women scientists thrive. The book is presented in an informative and entertaining way, dotted with scientific gossip and anecdotes, and can be enjoyed even without the reader''s actual presence in the city. Over eight hundred photographs illustrate the book. They may induce the reader to make their own discoveries in New York.

If science has the equivalent of a Bloomsbury group, it is the five men born at the turn of the 20th century in the same neighborhood in Budapest: Theodore von Karman, Leo Szilard, Eugene Wigner, John von Neumann, and Edward Teller. Through immigration from Hungary to Germany to the United States, they remained friends and continued to work together and influence each other throughout their lives. As a result, their work was integral to some of the most important scientific and political developments of the 20th century.They were an extraordinary group of talents: Wigner won a Nobel Prize in theoretical physics without ever having taken a formal college-level physics course, Szilard was the first to see that a chain reaction based on neutrons was possible but left physics to try to restrict nuclear arms, von Neumann could solve problems in his head for which most people needed computers, von Karman became the first director of NASA's Jet Propulsion Lab, and Teller was the father of the hydrogen bomb, whose name is now synonymous with the controversial "Star Wars" defense initiative of the 1980s. Each was fiercely opinionated and politically active, reactionaries against the fascism and anti-Semitism with which they had grown up. Istvan Hargittai, as a young Hungarian physicist, was able to get to know these great men in their later years, and the depth of information and human interest in this book is the result of his personal relationships with the subjects, their families and their contemporaries.

Modern experimental and computational techniques are capable of determining bond lengths and angles with precisions of a few thousandths of an oangström and a few tenths of a degree. Such precisions are meaningful only if they are coupled with rigorous error analysis and careful evaluation of the physical meaning of the parameters.Here, internationally respected authors present all modern experimental and computational techniques for the determination of accurate molecular structures for the first time in one volume. They establish guidelines for accuracy requirements in answering broadly varying questions in current chemical research.

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.

Istv?n Hargittai tells the story of this remarkable group: Wigner won a Nobel Prize in theoretical physics; Szilard was the first to see that a chain reaction based on neutrons was possible, initiated the Manhattan Project, but left physics to try to restrict nuclear arms; von Neumann could solve difficult problems in his head and developed the modern computer for more complex problems; von K?rm?n became the first director of NASA''s Jet Propulsion Laboratory, providing the scientific basis for the U.S. Air Force; and Teller was the father of the hydrogen bomb, whose name is now synonymous with the controversial "Star Wars" initiative of the 1980s. Each was fiercely opinionated, politically active, and fought against all forms of totalitarianism. Hargittai, as a young Hungarian physical chemist, was able to get to know some of these great men in their later years, and the depth of information and human interest in The Martians of Science is the result of his personal relationships with the subjects, their families, and their contemporaries.

The apex of Soviet science as seen through the lives of twelve of the USSR's most eminent researchersMoscow's Novodevichy Cemetery is the final resting place of some of Russia's most celebrated figures, from Khrushchev and Yeltsin to Anton Chekhov, Sergei Eisenstein, Nikolai Gogol, and Mikhail Bulgakov. Using this famed cemetery as symbolic starting point, Buried Glory profiles a dozen eminent Soviet scientists-nine of whom are buried at Novodevichy-men who illustrate both the glorious heights of Soviet research as well as the eclipse of science since the collapse of the USSR.Drawing on extensive archival research and his own personal memories, renowned chemist Istvan Hargittai bring these figures back to life, placing their remarkable scientific achievements against the tense political backdrop of the Cold War. Among the eminent scientists profiled here are Petr L. Kapitza, one of the most brilliant representatives of the great generation of Soviet physicists, a Nobel-Prize winner who risked his career-and his life-standing up for fellow scientists against Stalin. Yulii B. Khariton, who ran the highly secretive Soviet nuclear weapons laboratory, Arzamas-16, despite being Jewish and despite the fact that his father Boris had been sent to the labor camps. And Andrei D. Sakharov, the "father of the Soviet hydrogen bomb " and a brilliant fighter for human rights, for which he won the Nobel Peace Prize. Along the way, Hargittai shines a light on the harrowing conditions under which these brilliant researchers excelled. Indeed, in the post-war period, Stalin's anti-Semitism and ongoing anti-science measures devastated biology, damaged chemistry, and nearly destroyed physics. The latter was saved only because Stalin realized that without physics and physicists there could be no nuclear weapons.The extraordinary scientific talent nurtured by the Soviet regime belongs almost entirely to the past. Buried Glory is both a fitting tribute to these great scientists and a fascinating account of scientific work behind the Iron Curtain.

In this timely volume, scientists examine the physical, structural, and analytical chemistry of fuel combustion. Their contributions also address the issue of combustion efficiency and how air quality can be protected or improved. Supported by numerous illustrations, this volume be appreciated by researchers and students working in various areas of chemistry.

Inquiring into the nature of scientific discovery, this text focuses on six personalities and six scientific fields: Johannes Kepler and modelling, Buckminster Fuller and molecules, Linus Pauling and helices of biological systems, A. Kitaiigorodskii and packing of shapes, D.J. Bernal and quasicrystals, and Pierre Curie and symmetry breaking. Excerpts from conversations with 40 leading scientists, including 17 Nobel laureates, enliven the discussion. Culture and science blend inseparably in this book and natural curiosity is the only prerequisite to enjoy it. The authors created this book for the interested general public.

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.

The study of the structure of molecular systems is an enduring area of research. This series is devoted to bringing together articles from leading workers in the field that draw together recent theoretical and experimental results and advances in understanding.

The accurate determination of the structure of molecular systems provides information about the consequences of weak interactions both within and between molecules. These consequences impact the properties of the materials and the behaviour in interactions with other substances. The book presents modern experimental and computational techniques for the determination of molecular structure. It also highlights applications ranging from the simplest molecules to DNA and industrially significant materials.Readership: Graduate students and researchers in structural chemistry, computational chemistry, molecular spectroscopy, crystallography, supramolecular chemistry, solid state chemistry and physics, and materials science.

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 Chapter3. 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.

In this timely volume, scientists examine examine the physical, structural, and analytical chemistry of fuel combustion. Their contributions also address the issue of combustion efficiency and how air quality can be protected or improved. Supported by numerous illustrations, this volume be appreciated by researchers and students working in various areas of chemistry.

The title of our volume refers to what is well described by the following two quota­ tions:"Godcreated man in his own image"l and "Man creates God in his own image."2 Our approach to symmetry is subjective, and the term "personal" symmetry reflects this approach in our discussion of selected scientific events. We have chosen six icons to symbolize six areas: Kepler for modeling, Fuller for new molecules, Pauling for helical structures, Kitaigorodskii for packing, Bernal for quasicrystals, and Curie for dissymmetry. For the past three decades we have been involved in learning, thinking, speaking, and writing about symmetry. This involvement has augmented our principal activities in molecular structure research. Our interest in symmetry had started with a simple fascination and has evolved into a highly charged personal topic for us. At the start of this volume, we had had several authored and edited symmetry related books behind 3 us. We owe a debt of gratitude to the numerous people whose interviews are quoted 4 in this volume. We very much appreciate the kind and gracious cooperation of Edgar J. Applewhite (Washington, DC), Lawrence S. Bartell (University of Michigan), R.
