في معظم التخصصات العلمية، يسود فهم بأن الفرضية المثبتة يمكن قبولها بصفتها "حقيقة" علمية، ولكن إلى أن تستطيع نظرية جديدة دحضها وتقديم نموذج جديد. وبهذه الطريقة يتطور العلم ويتسع نطاقه، إذ تحل الأفكار الجديدة محل القديمة. لكن الاستثناء هنا هو علم الرياضيات، حيث إنه بمجرد إثبات صحة المبرهنة (تقديم برهانها)، فإنها تظل صحيحة بشكل دائم، ولا يمكن دحضها. في الواقع، على الرغم من انتماء الرياضيات إلى العلوم بالمعنى الأوسع؛ لاحتوائها على المعرفة المنهجية والمعادلاتية، فإنها تختلف اختلافًا كبيرًا عن العلوم الطبيعية، التي تبحث في الكون المادي. وفي حين تجمع العلوم الطبيعية أدلة تجريبية لابتكار

In space, no one can hear you scream. But the universe is far from silent. It’s been speaking all along, broadcasting its stories and secrets, for those who know how to listen. In The Echoing Universe, Emma Chapman tunes us in to the universe and what it is trying to say, through the science of radio astronomy. Everything, from the surface of the Moon to distant stars, is sending out signals—maybe even extraterrestrials.

The Essential Einstein: Public Writings presents a rich selection of Einstein's humanistic writings drawn from a diverse array of materials he sanctioned for publication during his lifetime. Distinct from previous collections, this incisive book presents previously excerpted works in their entirety, including key articles, lectures, and speeches.

In a time when our political and cultural views feel more polarized than ever, Tyson provides a much-needed antidote to so much of what divides us, while making a passionate case for the twin chariots of enlightenment—a cosmic perspective and the rationality of science. After thinking deeply about how science sees the world and about Earth as a planet, the human brain has the capacity to reset and recalibrates life’s priorities, shaping the actions we might take in response. No outlook on culture, society, or civilization remains untouched.

We humans like to think of ourselves as rational creatures who, as a species, have relied on calculation and intellect to survive. But many of the most important moments in our history had little to do with cold hard facts and a lot to do with feelings. In A Human History of Emotion, Richard Firth-Godbehere takes listeners on a fascinating and wide ranging tour of the central and often under-appreciated role emotions have played in human societies around the world and throughout history.

The periodic table is one of the most potent icons in science. It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time. The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike.

More than 200 million years ago, geological forces split apart the continents. Isolated from each other, the two halves of the world developed radically different suites of plants and animals. When Christopher Columbus set foot in the Americas, he ended that separation at a stroke. Driven by the economic goal of establishing trade with China, he accidentally set off an ecological convulsion as European vessels carried thousands of species to new homes across the oceans.

Since the fall of the Soviet Union, long-suppressed information has emerged on Heisenberg’s role in the Nazi atomic bomb project. In Beyond Uncertainty, Cassidy interprets this and other previously unknown material within the context of his vast research and tackles the vexing questions of a scientist’s personal responsibility and guilt when serving an abhorrent military regime.

A belief in free will touches nearly everything that human beings value. It is difficult to think about law, politics, religion, public policy, intimate relationships, morality—as well as feelings of remorse or personal achievement—without first imagining that every person is the true source of his or her thoughts and actions. And yet the facts tell us that free will is an illusion.

Empathy is in short supply. We struggle to understand people who aren’t like us, but find it easy to hate them. Studies show that we are less caring than we were even 30 years ago. In 2006, Barack Obama said that the United States was suffering from an “empathy deficit.” Since then, things seem to have only gotten worse. In this groundbreaking book, Jamil Zaki shares cutting-edge research, including experiments from his own lab, showing that empathy is not a fixed trait - something we’re born with or not - but rather a skill that can be strengthened through effort.

This sweeping exploration of the impact of epidemic diseases looks at how mass infectious outbreaks have shaped society, from the Black Death to today, and in a new preface addresses the global threat of COVID-19. In a clear and accessible style, Frank M. Snowden reveals the ways that diseases have not only influenced medical science and public health, but also transformed the arts, religion, intellectual history, and warfare.

Everyone has heard of DNA. But by itself, DNA is just an inert blueprint for life. It is the ribosome - an enormous molecular machine made up of a million atoms - that makes DNA come to life, turning our genetic code into proteins and therefore into us. Gene Machine is an insider account of the race for the structure of the ribosome, a fundamental discovery that both advances our knowledge of all life and could lead to the development of better antibiotics against life-threatening diseases.

We would like to believe we can know things for certain. We want to be able to figure out who will win an election, if the stock market will crash, or if a suspect definitely committed a crime. But the odds are not in our favor. Life is full of uncertainty - indeed, scientific advances indicate that the universe might be fundamentally inexact - and humans are terrible at guessing. When asked to predict the outcome of a chance event, we are almost always wrong.

Humanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes - good and bad - are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and best-selling author Martin Rees argues that humanity’s prospects depend on our taking a very different approach to planning for tomorrow.

The answers to these questions are right behind our eyes. The greatest technology we have ever discovered on our planet is the three-pound organ carried in the vault of the skull. This book is not simply about what the brain is; it is about what it does. The magic of the brain is not found in the parts it’s made of but in the way those parts unceasingly reweave themselves in an electric, living fabric.

The Large Hadron Collider is the biggest, and by far the most powerful, machine ever built. A project of CERN, the European Organization for Nuclear Research, its audacious purpose is to re-create, in a 16.5-mile-long circular tunnel under the French-Swiss countryside, the immensely hot and dense conditions that existed some 13.7 billion years ago within the first trillionth of a second after the fiery birth of our Universe. The collider is now crashing protons at record energy levels never created by scientists before, and it will reach even higher levels by 2013.

Modern science is pivotal in our understanding of race - not because of the lines that thinkers through the centuries have chosen to trace but because, once grouped, what they thought belonging to these groups signified. In Superior, award-winning science writer Angela Saini explores the concept of race, both past and present. At its heart, race is the belief that we are born different, in character and intellectually as well as in appearance.

For as long as we’ve studied human cognition, we’ve believed that our senses give us direct access to the world. What we see is what’s really there—or so the thinking goes. But new discoveries in neuroscience and psychology have turned this assumption on its head. What if rather than perceiving reality passively, your mind actively predicts it?

How much light is too much light? Satellite pictures show our planet as a brightly glowing orb, and in our era of constant illumination, light pollution has become a major issue. The world’s flora and fauna have evolved to operate in the natural cycle of day and night. But in the last 150 years, we have extended our day—and in doing so have forced out the inhabitants of the night and disrupted the circadian rhythms necessary to sustain all living things, including ourselves.

We are told that modern science was invented in Europe, the product of great minds like Nicolaus Copernicus, Isaac Newton, Charles Darwin and Albert Einstein. But this is wrong. Science is not, and has never been, a uniquely European endeavour. Horizons pushes beyond Europe, exploring the ways in which scientists from Africa, America, Asia and the Pacific fit into the history of science, and arguing that it is best understood as a story of global cultural exchange.
