Statistical Consequences of Fat Tails: Real World Preasymptotics, Epistemology, and Applications
Nassim Nicholas Taleb - 2020
Switching from thin tailed to fat tailed distributions requires more than "changing the color of the dress." Traditional asymptotics deal mainly with either n=1 or n=∞, and the real world is in between, under the "laws of the medium numbers"-which vary widely across specific distributions. Both the law of large numbers and the generalized central limit mechanisms operate in highly idiosyncratic ways outside the standard Gaussian or Levy-Stable basins of convergence. A few examples: - The sample mean is rarely in line with the population mean, with effect on "na�ve empiricism," but can be sometimes be estimated via parametric methods. - The "empirical distribution" is rarely empirical. - Parameter uncertainty has compounding effects on statistical metrics. - Dimension reduction (principal components) fails. - Inequality estimators (Gini or quantile contributions) are not additive and produce wrong results. - Many "biases" found in psychology become entirely rational under more sophisticated probability distributions. - Most of the failures of financial economics, econometrics, and behavioral economics can be attributed to using the wrong distributions. This book, the first volume of the Technical Incerto, weaves a narrative around published journal articles.

Colossus: The Rise and Fall of the American Empire
Niall Ferguson - 2004
Despite the conquest of two sovereign states in as many years, despite the presence of more than 750 military installations in two thirds of the world's countries and despite his stated intention to extend the benefits of freedom...to every corner of the world, George W. Bush maintains that America has never been an empire. We don't seek empires, insists Defense Secretary Rumsfeld. We're not imperialistic.Nonsense, says Niall Ferguson. In Colossus he argues that in both military and economic terms America is nothing less than the most powerful empire the world has ever seen. Just like the British Empire a century ago, the United States aspires to globalize free markets, the rule of law, and representative government. In theory it's a good project, says Ferguson. Yet Americans shy away from the long-term commitments of manpower and money that are indispensable if rogue regimes and failed states really are to be changed for the better. Ours, he argues, is an empire with an attention deficit disorder, imposing ever more unrealistic timescales on its overseas interventions. Worse, it's an empire in denial--a hyperpower that simply refuses to admit the scale of its global responsibilities. And the negative consequences will be felt at home as well as abroad. In an alarmingly persuasive final chapter Ferguson warns that this chronic myopia also applies to our domestic responsibilities. When overstretch comes, he warns, it will come from within--and it will reveal that more than just the feet of the American colossus is made of clay.
FAB: The Coming Revolution on Your Desktop–from Personal Computers to Personal Fabrication
Neil Gershenfeld - 2005
According to Neil Gershenfeld, the renowned MIT scientist and inventor, the next big thing is personal fabrication–the ability to design and produce your own products, in your own home, with a machine that combines consumer electronics with industrial tools. Personal fabricators (PF’s) are about to revolutionize the world just as personal computers did a generation ago. PF’s will bring the programmability of the digital world to the rest of the world, by being able to make almost anything-including new personal fabricators. In FAB, Gershenfeld describes how personal fabrication is possible today, and how it is meeting local needs with locally developed solutions. He and his colleagues have created “fab labs” around the world, which, in his words, can be interpreted to mean “a lab for fabrication, or simply a fabulous laboratory.” Using the machines in one of these labs, children in inner-city Boston have made saleable jewelry from scrap material. Villagers in India used their lab to develop devices for monitoring food safety and agricultural engine efficiency. Herders in the Lyngen Alps of northern Norway are developing wireless networks and animal tags so that their data can be as nomadic as their animals. And students at MIT have made everything from a defensive dress that protects its wearer’s personal space to an alarm clock that must be wrestled into silence. These experiments are the vanguard of a new science and a new era-an era of “post-digital literacy” in which we will be as familiar with digital fabrication as we are with the of information processing. In this groundbreaking book, the scientist pioneering the revolution in personal fabrication reveals exactly what is being done, and how. The technology of FAB will allow people to create the objects they desire, and the kind of world they want to live in.

The Evolution of Cooperation
Robert Axelrod - 1984
Widely praised and much-discussed, this classic book explores how cooperation can emerge in a world of self-seeking egoists—whether superpowers, businesses, or individuals—when there is no central authority to police their actions. The problem of cooperation is central to many different fields. Robert Axelrod recounts the famous computer tournaments in which the “cooperative” program Tit for Tat recorded its stunning victories, explains its application to a broad spectrum of subjects, and suggests how readers can both apply cooperative principles to their own lives and teach cooperative principles to others.

The Shock of the Old: Technology and Global History Since 1900
David Edgerton - 2006
Wells to the press releases of NASA, we are awash in clich�d claims about high technology's ability to change the course of history. Now, in The Shock of the Old, David Edgerton offers a startling new and fresh way of thinking about the history of technology, radically revising our ideas about the interaction of technology and society in the past and in the present. He challenges us to view the history of technology in terms of what everyday people have actually used-and continue to use-rather than just sophisticated inventions. Indeed, many highly touted technologies, from the V-2 rocket to the Concorde jet, have been costly failures, while many mundane discoveries, like corrugated iron, become hugely important around the world. Edgerton reassesses the significance of such acclaimed inventions as the Pill and information technology, and underscores the continued importance of unheralded technology, debunking many notions about the implications of the information age. A provocative history, The Shock of the Old provides an entirely new way of looking historically at the relationship between invention and innovation.
Complexity: The Emerging Science at the Edge of Order and Chaos
M. Mitchell Waldrop - 1992
The science of complexity studies how single elements, such as a species or a stock, spontaneously organize into complicated structures like ecosystems and economies; stars become galaxies, and snowflakes avalanches almost as if these systems were obeying a hidden yearning for order. Drawing from diverse fields, scientific luminaries such as Nobel Laureates Murray Gell-Mann and Kenneth Arrow are studying complexity at a think tank called The Santa Fe Institute. The revolutionary new discoveries researchers have made there could change the face of every science from biology to cosmology to economics. M. Mitchell Waldrop's groundbreaking bestseller takes readers into the hearts and minds of these scientists to tell the story behind this scientific revolution as it unfolds.
Thinking in Systems: A Primer
Donella H. Meadows - 2008
Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life.Some of the biggest problems facing the world—war, hunger, poverty, and environmental degradation—are essentially system failures. They cannot be solved by fixing one piece in isolation from the others, because even seemingly minor details have enormous power to undermine the best efforts of too-narrow thinking.While readers will learn the conceptual tools and methods of systems thinking, the heart of the book is grander than methodology. Donella Meadows was known as much for nurturing positive outcomes as she was for delving into the science behind global dilemmas. She reminds readers to pay attention to what is important, not just what is quantifiable, to stay humble, and to stay a learner.In a world growing ever more complicated, crowded, and interdependent, Thinking in Systems helps readers avoid confusion and helplessness, the first step toward finding proactive and effective solutions.

Class War: The Privatization of Childhood
Megan Erickson - 2015
Public schools, tasked with providing education, childcare, job training, meals, and social services to low-income children, struggle with cutbacks. Meanwhile, private schools promise to nurture the minds and personalities of future professionals to the tune of $40,000 a year. As Class War reveals, this situation didn’t happen by chance.In the media, educational success is framed as a consequence of parental choices and natural abilities. In truth the wealthy are ever more able to secure advantages for their children, deepening the rifts between rich and poor. The longer these divisions persist, the worse the consequences.Drawing on Erickson’s own experience as a teacher in the New York City school system, Class War reveals how modern education has become the real “hunger games,” stealing opportunity and hope from disadvantaged children for the benefit of the well-to-do.
