" Valence Shell Electron Pair Repulsion (VSEPR) theory is a simple technique for predicting the geometry of atomic centers in small molecules and molecular ions. This authoritative reference, written by the developer of VSEPR theory features extensive coverage of structural information as well as theory and applications. Helpful data on molecular geometries, bond lengths, and band angles appear in tables and other graphics. 1991 edition"--
By addressing the enigma of the exceptional success of Hungarian emigrant scientists and telling their life stories, Brilliance in Exile combines scholarly analysis with fascinating portrayals of uncommon personalities. István and Balazs Hargittai discuss the conditions that led to five different waves of emigration of scientists from the early twentieth century to the present. Although these exodes were driven by a broad variety of personal motivations, the attraction of an open society with inclusiveness, tolerance, and – needless to say – better circumstances for working and living, was the chief force drawing them abroad. While emigration from East to West is a general phenomenon, this book explains why and how the emigration of Hungarian scientists is distinctive. The high number of Nobel Prizes among this group is only one indicator. Multicultural tolerance, a quickly emerging, considerably Jewish, urban middle class, and a very effective secondary school system were positive legacies of the Austro-Hungarian Monarchy. Multiple generations, shaped by these conditions, suffered from the increasingly exclusionist, intolerant, antisemitic, and economically stagnating environment, and chose to go elsewhere. "I would rather have roots than wings, but if I cannot have roots, I shall use wings," explained Leo Szilard, one of the fathers of the Atom Bomb.
Hargittai tells the story of five remarkable Hungarians: 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 Kármán 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.
