In theory, at least, gravitational waves do exist. We are constantly bathed in gravitational radiation, which is generated when stars explode or collide and a portion of their mass becomes energy that ripples out like a disturbance on the surface of a serene pond. But unfortunately no gravitational wave has ever been directly detected even though the search has lasted more than forty years.

As the leading chronicler of the search for gravitational waves, Harry Collins has been right there with the scientists since the start. The result of his unprecedented access to the front lines of physical science is Gravity’s Ghost, a thrilling chronicle of high-stakes research and cutting-edge discovery. Here, Collins reveals that scientific discovery and nondiscovery can turn on scientific traditions and rivalries, that ideal statistical analysis rests on impossible procedures and unattainable knowledge, and that fact in one place is baseless assumption in another. He also argues that sciences like gravitational wave detection, in exemplifying how the intractable is to be handled, can offer scientific leadership a moral beacon for the twenty-first century. In the end, Gravity’s Ghost shows that discoveries are the denouements of dramatic scientific mysteries.

What does it mean to be an expert? In Rethinking Expertise, Harry Collins and Robert Evans offer a radical new perspective on the role of expertise in the practice of science and the public evaluation of technology. Collins and Evans present a Periodic Table of Expertises based on the idea of tacit knowledge—knowledge that we have but cannot explain. They then look at how some expertises are used to judge others, how laypeople judge between experts, and how credentials are used to evaluate them. Throughout, Collins and Evans ask an important question: how can the public make use of science and technology before there is consensus in the scientific community? This book has wide implications for public policy and for those who seek to understand science and benefit from it. “Starts to lay the groundwork for solving a critical problem—how to restore the force of technical scientific information in public controversies, without importing disguised political agendas.”—Nature “A rich and detailed ‘periodic table’ of expertise . . . full of case studies, anecdotes and intriguing experiments.”—Times Higher Education Supplement (UK)

Much of what humans know we cannot say. And much of what we do we cannot describe. For example, how do we know how to ride a bike when we can’t explain how we do it? Abilities like this were called “tacit knowledge” by physical chemist and philosopher Michael Polanyi, but here Harry Collins analyzes the term, and the behavior, in much greater detail, often departing from Polanyi’s treatment. In Tacit and Explicit Knowledge, Collins develops a common conceptual language to bridge the concept’s disparate domains by explaining explicit knowledge and classifying tacit knowledge. Collins then teases apart the three very different meanings, which, until now, all fell under the umbrella of Polanyi’s term: relational tacit knowledge (things we could describe in principle if someone put effort into describing them),  somatic tacit knowledge (things our bodies can do but we cannot describe how, like balancing on a bike), and collective tacit knowledge (knowledge we draw that is the property of society, such as the rules for language). Thus, bicycle riding consists of some somatic tacit knowledge and some collective tacit knowledge, such as the knowledge that allows us to navigate in traffic. The intermixing of the three kinds of tacit knowledge has led to confusion in the past; Collins’s book will at last unravel the complexities of the idea. Tacit knowledge drives everything from language, science, education, and management to sport, bicycle riding, art, and our interaction with technology.  In Collins’s able hands, it also functions at last as a framework for understanding human behavior in a range of disciplines.

What can humans do? What can machines do? How do humans delegate actions to machines? In this book, Harry Collins and Martin Kusch combine insights from sociology and philosophy to provide a novel answer to these increasingly important questions.The authors begin by distinguishing between two basic types of intentional behavior, which they call polimorphic actions and mimeomorphic actions. Polimorphic actions (such as writing a love letter) are ones that community members expect to vary with social context. Mimeomorphic actions (such a swinging a golf club) do not vary. Although machines cannot act, they can mimic mimeomorphic actions. Mimeomorphic actions are thus the crucial link between what humans can do and what machines can do.

Following a presentation of their detailed categorization of actions, the authors apply their approach to a broad range of human-machine interactions and to learning. Key examples include bicycle riding and the many varieties of writing machines. They also show how their theory can be used to explain the operation of organizations such as restaurants and armies. Finally, they look at a historical case—the technological development of the air pump—applying their categorization of actions to the processes of mechanization and automation. Automation, they argue, can occur only where what we want to bring about can be brought about through mimeomorphic action.

How technologies can get it wrong in sports, and what the consequences are—referees undermined, fans heartbroken, and the illusion of perfect accuracy maintained.

Good call or bad call, referees and umpires have always had the final say in sports. Bad calls are more visible: plays are televised backward and forward and in slow motion. New technologies—the Hawk-Eye system used in tennis and cricket, for example, and the goal-line technology used in English football—introduced to correct bad calls sometimes get it right and sometimes get it wrong, but always undermine the authority of referees and umpires. Bad Call looks at the technologies used to make refereeing decisions in sports, analyzes them in action, and explains the consequences.

Used well, technologies can help referees reach the right decision and deliver justice for fans: a fair match in which the best team wins. Used poorly, however, decision-making technologies pass off statements of probability as perfect accuracy and perpetuate a mythology of infallibility. The authors re-analyze three seasons of play in English Premier League football, and discover that goal line technology was irrelevant; so many crucial wrong decisions were made that different teams should have won the Premiership, advanced to the Champions League, and been relegated. Simple video replay could have prevented most of these bad calls. (Major League baseball learned this lesson, introducing expanded replay after a bad call cost Detroit Tigers pitcher Armando Galarraga a perfect game.)

What matters in sports is not computer-generated projections of ball position but what is seen by the human eye—reconciling what the sports fan sees and what the game official sees.

A fascinating account, written in real time, of the unfolding of a scientific discovery: the first detection of gravitational waves.

Scientists have been trying to confirm the existence of gravitational waves for fifty years. Then, in September 2015, came a “very interesting event” (as the cautious subject line in a physicist''s email read) that proved to be the first detection of gravitational waves. In Gravity''s Kiss, Harry Collins—who has been watching the science of gravitational wave detection for forty-three of those fifty years and has written three previous books about it—offers a final, fascinating account, written in real time, of the unfolding of one of the most remarkable scientific discoveries ever made.

Predicted by Einstein in his theory of general relativity, gravitational waves carry energy from the collision or explosion of stars. Dying binary stars, for example, rotate faster and faster around each other until they merge, emitting a burst of gravitational waves. It is only with the development of extraordinarily sensitive, highly sophisticated detectors that physicists can now confirm Einstein''s prediction. This is the story that Collins tells.

Collins, a sociologist of science who has been embedded in the gravitational wave community since 1972, traces the detection, the analysis, the confirmation, and the public presentation and the reception of the discovery—from the first email to the final published paper and the response of professionals and the public. Collins shows that science today is collaborative, far-flung (with the physical location of the participants hardly mattering), and sometimes secretive, but still one of the few institutions that has integrity built into it.

To ordinary people, science used to seem infallible. Scientists were heroes, selflessly pursuing knowledge for the common good. More recently, a series of scientific scandals, frauds and failures have led us to question science’s pre-eminence. Revelations such as Climategate, or debates about the safety of the MMR vaccine, have dented our confidence in science.

In this provocative new book Harry Collins seeks to redeem scientific expertise, and reasserts science’s special status. Despite the messy realities of day-to-day scientific endeavor, he emphasizes the superior moral qualities of science, dismissing the dubious “default” expertise displayed by many of those outside the scientific community. Science, he argues, should serve as an example to ordinary citizens of how to think and act, and not the other way round.
