This guide highlights the place of translation in our culture, encouraging awareness of the process of translating and the choices involved, making the translator more 'visible'. Concentrating on major writers and works, it covers translations out of many languages, from Greek to Hungarian, Korean to Turkish. For some works (e.g. Virgil's Aeneid) which have been much translated, the discussion is historical and critical, showing how translation has evolved over the centuries and bringing out the differences between versions. Elsewhere, with less familiar literatures, the Guide examines the extent to which translation has done justice to the range of work available.

A Tale of Seven Elements

In 1913, English physicist Henry Moseley established an elegant method for "counting" the elements based on atomic number, ranging them from hydrogen (#1) to uranium (#92). It soon became clear, however, that seven elements were mysteriously missing from the lineup--seven elements unknown to science. In his well researched and engaging narrative, Eric Scerri presents the intriguing stories of these seven elements--protactinium, hafnium, rhenium, technetium, francium, astatine and promethium. The book follows the historical order of discovery, roughly spanning the two world wars, beginning with the isolation of protactinium in 1917 and ending with that of promethium in 1945. For each element, Scerri traces the research that preceded the discovery, the pivotal experiments, the personalities of the chemists involved, the chemical nature of the new element, and its applications in science and technology. We learn for instance that alloys of hafnium--whose name derives from the Latin name for Copenhagen (hafnia)--have some of the highest boiling points on record and are used for the nozzles in rocket thrusters such as the Apollo Lunar Modules. Scerri also tells the personal tales of researchers overcoming great obstacles. We see how Lise Meitner and Otto Hahn--the pair who later proposed the theory of atomic fission--were struggling to isolate element 91 when World War I intervened, Hahn was drafted into the German army's poison gas unit, and Meitner was forced to press on alone against daunting odds. The book concludes by examining how and where the twenty-five new elements have taken their places in the periodic table in the last half century. A Tale of Seven Elements paints a fascinating picture of chemical research--the wrong turns, missed opportunities, bitterly disputed claims, serendipitous findings, accusations of dishonesty--all leading finally to the thrill of discovery.

In the mid-nineteenth century, chemists came to the conclusion that elements should be organized by their atomic weights. However, the atomic weights of various elements were calculated erroneously, and chemists also observed some anomalies in the properties of other elements. Over time, it became clear that the periodic table as currently comprised contained gaps, missing elements that had yet to be discovered. A rush to discover these missing pieces followed, and a seemingly endless amount of elemental discoveries were proclaimed and brought into laboratories. It wasn't until the discovery of the atomic number in 1913 that chemists were able to begin making sense of what did and what did not belong on the periodic table, but even then, the discovery of radioactivity convoluted the definition of an element further. Throughout its formation, the periodic table has seen false entries, good-faith errors, retractions, and dead ends; in fact, there have been more elemental discoveries" that have proven false than there are current elements on the table. The Lost Elements: The Shadow Side of Discovery collects the most notable of these instances, stretching from the nineteenth century to the present. The book tells the story of how scientists have come to understand elements, by discussing the failed theories and false discoveries that shaped the path of scientific progress. Chapters range from early chemists' stubborn refusal to disregard alchemy as legitimate practice, to the effects of the atomic number on discovery, to the switch in influence from chemists to physicists, as elements began to be artificially created in the twentieth century. Along the way, Fontani, Costa, and Orna introduce us to the key figures in the development of the periodic table as we know it. And we learn, in the end, that this development was shaped by errors and gaffs as much as by correct assumptions and scientific conclusions."

Ein neuer Titel des Erfolgsautors John Emsley über ein packendes Thema: Die Lebensgeschichte des Phosphors, des ominösen 13. Elements, beginnt zu einer Zeit, als vielen Stoffen noch eine magische Bedeutung zugeschrieben wurde. Durch Zufall entdeckt auf der Suche nach dem Stein der Weisen, wurde der Phosphor berühmt durch sein gespenstisches Leuchten und berüchtigt als langsam wirkendes Gift, dessen tödliche Wirkung zahlreiche mysteriöse Morde belegen. Er besitzt noch viele Facetten, sei es als Kunstdünger, der die Landwirtschaft revolutionierte oder als Bestandteil der berühmtesten Limonade der Welt. Phosphorverbindungen machen Stoffe schwerer entflammbar und die Wäsche weißer, sind aber auch die Grundlage für viele chemische Kampfstoffe. So ist Phosphor seit jeher mit dem Ruch des Teuflischen umgeben, eben ein Element auf Leben und Tod.

This is a book about discovery and disaster, exploitation and invention, warfare and science - and the relationship between human beings and the chemical elements that make up our planet. Lars Ohrstrom introduces us to a variety of elements from S to Pb through tales of ordinary and extraordinary people from around the globe. We meet African dictators controlling vital supplies of uranium; eighteenth-century explorers searching out sources of precious metals; industrial spies stealing the secrets of steel-making. We find out why the Hindenburg airship was tragically filled with hydrogen, not helium; why nail-varnish remover played a key part in World War I; and the real story behind the legend of tin buttons and the downfall of Napoleon. In each chapter, we find out about the distinctive properties of each element and the concepts and principles that have enabled scientists to put it to practical use. These are the fascinating (and sometimes terrifying) stories of chemistry in action.

How can a chemical we need on a daily basis to keep us healthy be fatal at a different dose? Why should elements that are intrinsically dangerous be used in medicine? How did poisoners use the chemical properties of chemicals to cover their tracks? Emsley gives detailed histories of five of the most toxic elements - arsenic, antimony, lead, mercury, and thallium, highlighting some of the most famous murders and how the murderers used the chemical properties of elements to hide what they were doing. He shows how the elements have been behind many modern day environmental catastrophes including accidental mass poisonings from lead and arsenic, and the Minamata Bay Disaster in Japan. The array of fascinating stories shows how chemicals have impacted the lives of people ranging from the Greeks and Romans to Newton, Napoleon, Lucrezia Borgia, Mozart, Nelson Mandela, and Saddam Hussein. Emsley also touches on subjects close to home: cot deaths, laxatives, venereal disease, alleged cures for acne, hangovers, and insanity.
