Sinossi

First published in 1920.  According to the Foreword: "Although successful heavier-than-air flight is less than two decades old, and successful dirigible propulsion antedates it by a very short period, the mass of experiment and accomplishment renders any one-volume history of the subject a matter of
selection.  In addition to the restrictions imposed by space limits, the material for compilation is fragmentary, and, in many cases, scattered through periodical and other publications.  Hitherto, there has been no attempt at furnishing a detailed account of how the aeroplane and the dirigible of to-day came to being, but each author who has treated the subject has devoted his attention to some special phase or section. The principal exception to this rule--Hildebrandt--wrote in 1906, and a good many of his statements are inaccurate, especially with regard to heavier-than-air experiment."

    ‘A joy’ Philippe Sands‘Glorious’ David Spiegelhalter 
    A fascinating, enchanting and personal look at the meaning of luck, and the way in which it has shaped our shared history and continues to inflect our day to day lives. 
    What does it mean to be lucky? How might we mitigate the effects of bad luck and maximise those of good? Is there actually such a thing as ‘luck’—some force that intervenes between desire and its consummation, that impedes or hastens it? 
    To answer these questions, David Flusfeder sets out on a search for the definition of luck. This quest will take him to Siberia, Versailles, the Old Testament desert; play roulette in Baden-Baden with Dostoevsky; visit a Cambridge fairground with Wittgenstein; meet the sixteenth-century poet Thomas Bastard, who challenged Fortune, and lost; find Nietzsche on the slopes of Vesuvius; learn about the pioneers of probability; the twentieth-century art investigators of chance and possibility; and the intensely personal story of his father’s good fortune in escaping war-time Poland. Starting at the British Library in London, and following the dictates of an online randomiser that decided the chapter order, Flusfeder follows in the footsteps of some victors of luck and those who were defeated by it, from ancient times to the modern day. 
    Luck asks fundamental questions about the world, ourselves, our place in it. In these questions, about our relationships to fortune, to risk, to opportunity, to chance, destiny and fate, we find ourselves deciding who we are and how we might choose to live. 
    ‘Thrilling, intelligent and wilfully unique … I loved it’ James Runcie, author of The Great Passion 
    ‘Ruminative … page-turning’ TLS 
    ‘Fascinating … An eminently enjoyable and engrossing page-turner’ The Jewish Chronicle 
    In LUCK, David Flusfeder delves into the psychology of fortune, intertwining it with elements of mathematics and theory. The book is a top pick for those interested in the social aspects of games, particularly poker, and the communication skills required to navigate them. 
    For fans of Bill Perkins (Die With Zero), Cal Newport (Slow Productivity), Oliver Bullough (Moneyland), and Oliver Burkeman (Four Thousand Weeks).

    In addition to the wheelbarrow, the seismograph, the waterwheel, deep drilling, suspension bridges, and ship rudders, among countless other life-changing contraptions, the Chinese developed what were later dubbed the “Four Great Inventions of China.” Two of those were gunpowder and printing, which both spread through South Asia and the Middle East before making it to Europe.  
    For a time, gunpowder was a mere curiosity, but its destructive power and military potential would be realized quickly. The first record of a cannon in Europe comes from a manuscript written in 1326, which has an illustration showing an armored man with what looks like a slow match lighting a vase-shaped object. This crude cannon was called a pot de fer in French and vasi in Italian. While medieval engineers developed new types of cannons and explosives capable of destroying walls and castles, others were making the first handguns possible. European sources first mentioned the widespread use of handgonnes, as they were often called, in the late 14th century, precisely the time when gunpowder became cheaper.  
    	The history of printing was for ancient Asia an advancement in culture and communication, but for Europe in the 15th century, it was much more, plunging the continent into a new paradigm and aligning it for the modern world. Its importance is often overlooked, but the timeliness of the printing machine was equivalent to the invention of alphabets in antiquity and ranks up there with the digital revolution and the introduction of the internet. Put simply, it made the Renaissance possible and led to the modernization of Europe. Based on earlier Asian principles, Johannes Gutenberg’s movable type printing press propelled an industry that led to the education of the West and ultimately removed the tight grip of the Vatican from daily European life.

    When Bob Quinn was a kid, a stranger at a county fair gave him a few kernels of an unusual grain. Little did he know, that grain would change his life. Years later, after finishing a PhD in plant biochemistry and returning to his family's farm in Montana, Bob started experimenting with organic wheat. In the beginning, his concern wasn't health or the environment; he just wanted to make a decent living and some chance encounters led him to organics.  
     
    But as demand for organics grew, so too did Bob's experiments. He discovered that through time-tested practices like cover cropping and crop rotation, he could produce successful yields - without pesticides. Regenerative organic farming allowed him to grow fruits and vegetables in cold, dry Montana, providing a source of local produce to families in his hometown. He even started producing his own renewable energy. And he learned that the grain he first tasted at the fair was actually a type of ancient wheat, one that was proven to lower inflammation rather than worsening it, as modern wheat does.  
     
    Ultimately, Bob's forays with organics turned into a multimillion dollar heirloom grain company, Kamut International.
