The Lost Elements

The Periodic Table's Shadow Side

The Lost Elements

The Periodic Table of Elements hasn't always looked like it does now, a well-organized chart arranged by atomic number. In the mid-nineteenth century, chemists were of the belief that the elements should be sorted by atomic weight. However, the weights of many elements were calculated incorrectly, and over time it became clear that not only did the elements need rearranging, but that the periodic table contained many gaps and omissions: there were elements yet to be discovered, and the allure of finding one had scientists rushing to fill in the blanks. Supposed "discoveries" flooded laboratories, and the debate over what did and did not belong on the periodic table reached a fever pitch. With the discovery of radioactivity, the discourse only intensified. Throughout its formation, the Periodic Table of Elements has seen false entries, good-faith errors, retractions, and dead ends. In fact, there have been more falsely proclaimed elemental discoveries throughout history than there are elements on the table as we know it today. The Lost Elements: The Periodic Table's Shadow Side 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. We learn of early chemists' stubborn refusal to disregard alchemy as a legitimate practice, and of one German's supposed discovery of an elemental metal that breathed. As elements began to be created artificially in the twentieth century, we watch the discovery climate shift to favor the physicists, rather than the chemists. Along the way, Fontani, Costa, and Orna introduce us to the key figures in the development of today's periodic table, including Lavoisier and Mendeleev. Featuring a preface from Nobel Laureate Roald Hoffmann, The Lost Elements is an expansive history of the wrong side of chemical discovery-and reveals how these errors and gaffes have helped shape the table as much as any other form of scientific progress.

The Lost Empire of Atlantis

History's Greatest Mystery Revealed

The Lost Empire of Atlantis

The bestselling author of 1421: THE YEAR THE CHINESE DISCOVERED THE WORLD uncovers the truth behind the mystery of Atlantis. After a chance conversation in Egypt in 2008, bestselling historian Gavin Menzies launched himself on a quest that would reveal the truth behind the mystery of Atlantis and her destruction. Through an examination of documentary and academic research, metallurgy, ancient shipbuilding and navigation techniques, artefacts and DNA evidence, Menzies slowly and painstakingly reveals a trading empire that spanned from the Great Lakes in North America to Kerala in India. And in doing so finally explains the incredible reality behind the legendary civilisation described by Plato and its disappearance. Reading like a real-life Indiana Jones story as ex-Royal Navy submarine captain Menzies travels round the world in pursuit of his goal, this is epic, iconoclastic popular history.

The Power of Money

A Political-Economic Analysis with Special Emphasis on the American Economic System

The Power of Money

Money is both a vibrant, dynamic material substance and a social force that permeates industrial societies in their entirety. Yet significant aspects of how money works in society are concealed by myths, dogmas, and misperceptions. In The Power of Money Henry Bretton focuses on how money works in a democracy. He contends that the well-being of political democracy depends on a fuller understanding of the centrality of money in politics, and he presents his ideas on monetary policy, corruption and reform, banking and politics, private power within a democracy, money in international relations, and the system-destroying effects of money. Bretton considers the subject of money and democracy in the context of how monetarization of societies proceeded form antiquity to the Industrial Revolution, and he analyzes the formative years of the United States in terms of being based on political ideas that did not take account of monetarization. He reviews what social theorists and economists from Aristotle to Friedman have thought about the role of money in society and how it affects individual behavior and social norms. The link between economics and politics has been only partially explored, he contends, and he sees the major task for social scientists as developing a fuller integration of the two mainstreams of social theory, the political and the economic.
