Life is an enduring mystery. Yet, science tells us that living beings are merely sophisticated structures of lifeless molecules. If this view is correct, where do the seemingly purposeful motions of cells and organisms originate? In Life's Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale. Below the calm, ordered exterior of a living organism lies microscopic chaos, or what Hoffmann calls the molecular storm -- specialized molecules immersed in a whirlwind of colliding water molecules. Our cells are filled with molecular machines, which, like tiny ratchets, transform random motion into ordered activity, and create the "purpose" that is the hall...
The English version of the book has been extensively revised and expanded since its original publication in German. This edition includes a new preface and an updated bibliography.
"I am immortal!" exulted Hitler in the wake of the failed assassination plot of July 20, 1944. As Peter Hoffmann shows in this startling book, that bombing was only the best known of more than thirty attempts on Hitler's life, the first coming as early as 1921, when he was the leader of the German worker's party. Using extensive archival material, Hoffmann details these assassination plots and outlines the fanatically complex security measures that developed to keep Hitler safe. He analyzes Hitler's SS escort and the other security groups responsible for his life—there were so many of them that they often counteracted one another—together with their arrangements for his transportation, public appearances, residences, and wartime headquarters. Providing remarkable new information about the workings of those devoted to defending and destroying him, this book is an invaluable contribution to the history of the Third Reich.
Hoffmann examines the growing recognition by some Germans in the 1930s of the malign nature of the Nazi regime, the ways in which these people became involved in the resistance, and the views of those who staked their lives in the struggle against tyranny and murder.
New regulatory data reveal extensive price discrimination against non-financial clients in the FX derivatives market. The client at the 90th percentile pays an effective spread of 0.5%, while the bottom quarter incur transaction costs of less than 0.02%. Consistent with models of search frictions in over-the-counter markets, dealers charge higher spreads to less sophisticated clients. However, price discrimination is eliminated when clients trade through multi-dealer request-for-quote platforms. We also document that dealers extract rents from captive clients and market opacity, but only for contracts negotiated bilaterally with unsophisticated clients.
"While the "Valkyrie" plot to kill Hitler is the best known instance of German oppositon to his dictatorship, there were many other significant acts of resistance. Behind Valkyrie collects the documents, letters, and testimonies- many available in their entirety and in English for the first time- of Germans who fought Hitler from within."--P. [4] of cover.
How hydrogen -- nonpolluting and easy to produce -- could become the fuel of the future.
The attempt to assassinate Hitler is widely acknowledged, but few are aware of the individuals involved. In this detailed family history Peter Hoffmann reveals the tragic and heroic life of Claus, Count Stauffenberg, German aristocrat and would-be assassin of Adolph Hitler. --from publisher description.
In a world increasingly plagued by pollution, where limited availability of fossil fuels creates international tensions, and where global disaster from proliferating technology lurks on the horizon, the search for alternative synthetic fuels is no longer an idle scientist's dream—it is necessity. Hydrogen—with its vast and ready availability from water, its nearly universal utility, and its inherently benign characteristics—is one of several attractive synthetic fuels being considered for a "post-fossil-fuel" world, and it may well be the miracle fuel of the future. It is of special interest because, technically at least, it is so easily produced and because it produces simple water va...
Two Worlds tells the remarkable story of Arthur Philip Motley a Black American who as a young man left his home in McAlester City Oklahoma in 1928 to travel the 4351 miles across America and The Atlantic Ocean to come to Edinburgh Scotland to fulfil his dream to become a doctor. Edinburgh is the city of duality - the haunt of the doppelgänger - the home of Deacon Brodie and Dr Jekyll and Mr Hyde - and this chronicle tells a twin tale - of Black and White - of segregation and social integration - of Dr Motley's journey and the author's journey in search of him. It's the story of a man who over the course of six decades goes on to make an astonishing community contribution within a working class area in the capital going on to become a legendary figure whose story deserves a wider audience. But like us all his was a nuanced life which at its heart contained a dark secret.
