In his highly anticipated sequel to The Elements, Theodore Gray demonstrates how the elements of the periodic table combine to form the molecules that make up our world.Everything physical is made up of the elements and the infinite variety of molecules they form when they combine with each other. In Molecules, Theodore Gray takes the next step in the grand story that began with the periodic table in his best-selling book, The Elements: A Visual Exploration of Every Known Atom in the Universe. Here, he explores through fascinating stories and trademark stunning photography the most interesting, essential, useful, and beautiful of the millions of chemical structures that make up every material in the world.Gray begins with an explanation of how atoms bond to form molecules and compounds, as well as the difference between organic and inorganic chemistry. He then goes on to explore the vast array of materials molecules can create, including: soaps and solvents; goops and oils; rocks and ores; ropes and fibers; painkillers and dangerous drugs; sweeteners; perfumes and stink bombs; colors and pigments; and controversial compounds including asbestos, CFCs, and thimerosal.Big, gorgeous photographs, as well as diagrams of the compounds and their chemical bonds, rendered with never before seen beauty, fill the pages and capture molecules in their various states.As he did in The Elements, Gray shows us molecules as we\'ve never seen them before. It\'s the perfect book for his loyal fans who\'ve been eager for more and for anyone fascinated with the mysteries of the material world. Σελίδες: 240, Έτος Έκδοσης: 0424, Διαστάσεις: 25.5x25.5cm

From the stock market to covid-19, census figures to marketing email blasts, we are awash with data. But as anyone who has ever opened up a spreadsheet packed with seemingly infinite lines of data knows, numbers aren\'t enough: we need to know how to make those numbers talk. In The Model Thinker, social scientist Scott E. Page shows us the mathematical, statistical, and computational models-from linear regression to random walks and far beyond-that can turn anyone into a genius. At the core of the book is Page\'s \"many-model paradigm,\" which shows the reader how to apply multiple models to organize the data, leading to wiser choices, more accurate predictions, and more robust designs. Now culminating in an examination of how to use the multi-model approach to think about pandemics like covid-19, The Model Thinker provides a toolkit for business people, students, scientists, pollsters, and bloggers to make them better, clearer thinkers, able to leverage data and information to their advantage.

In this enthralling cosmic journey through space and time, astrophysicist Jillian Scudder locates our home planet within its own \'family tree\'. Our parent the Earth and its sibling planets in our solar system formed within the same gas cloud. Without our grandparent the Sun, we would not exist, and the Sun in turn relies on the Milky Way as its home. The Milky Way rests in a larger web of galaxies that traces its origins right back to tiny fluctuations in the very early universe.Following these cosmic connections, we discover the many ties that bind us to our universe. Based around readers\' questions from the author\'s popular blog \'Astroquizzical\', the book provides a quirky guide to how things work in the universe and why things are the way they are, from shooting stars on Earth, to black holes, to entire galaxies.For anyone interested in the \'big picture\' of how the cosmos functions and how it is all connected, Jillian Scudder is the perfect guide.

Our finances, politics, media, opportunities, information, shopping and knowledge production are mediated through algorithms and their statistical approaches to knowledge; increasingly, these methods form the organizational backbone of contemporary capitalism. Revolutionary Mathematics traces the revolution in statistics and probability that has quietly underwritten the explosion of machine learning, big data and predictive algorithms that now decide many aspects of our lives. Exploring shifts in the philosophical understanding of probability in the late twentieth century, Joque shows how this was not merely a technical change but a wholesale philosophical transformation in the production of knowledge and the extraction of value. This book provides a new and unique perspective on the dangers of allowing artificial intelligence and big data to manage society. It is essential reading for those who want to understand the underlying ideological and philosophical changes that have fueled the rise of algorithms and convinced so many to blindly trust their outputs, reshaping our current political and economic situation.

Bold and provocative, Regenesis tells of recent advances that may soon yield endless supplies of renewable energy, increased longevity and the return of long-extinct species.\", New Scientist In Regenesis , Harvard biologist George Church and science writer Ed Regis explore the possibilities,and perils,of the emerging field of synthetic biology. Synthetic biology, in which living organisms are selectively altered by modifying substantial portions of their genomes, allows for the creation of entirely new species of organisms. These technologies,far from the out-of-control nightmare depicted in science fiction,have the power to improve human and animal health, increase our intelligence, enhance our memory, and even extend our life span. A breathtaking look at the potential of this world-changing technology, Regenesis is nothing less than a guide to the future of life. Σελίδες: 304, Έτος Έκδοσης: 0408, Διαστάσεις: 17x17cm

This brilliantly illustrated tale of reason, insanity, love and truth recounts the story of Bertrand Russell\'s life. Raised by his paternal grandparents, young Russell was never told the whereabouts of his parents. Driven by a desire for knowledge of his own history, he attempted to force the world to yield to his yearnings: for truth, clarity and resolve. As he grew older, and increasingly sophisticated as a philosopher and mathematician, Russell strove to create an objective language with which to describe the world - one free of the biases and slippages of the written word. At the same time, he began courting his first wife, teasing her with riddles and leaning on her during the darker days, when his quest was bogged down by paradoxes, frustrations and the ghosts of his family\'s secrets. Ultimately, he found considerable success - but his career was stalled when he was outmatched by an intellectual rival: his young, strident, brilliantly original student, Ludwig Wittgenstein. An insightful and complexly layered narrative, Logicomix reveals both Russell\'s inner struggle and the quest for the foundations of logic. Narration by an older, wiser Russell, as well as asides from the author himself, make sense of the story\'s heady and powerful ideas. At its heart, Logicomix is a story about the conflict between pure reason and the persistent flaws of reality, a narrative populated by great and august thinkers, young lovers, ghosts and insanity.

The sheer volume of talk about energy, energy prices, and energy policy on both sides of the political aisle suggests that we must know something about these subjects. But according to Peter W. Huber and Mark P. Mills, the things we think we know are mostly myths. A better understanding of energy will radically change our views and policies on a number of very controversial issues. In The Bottomless Well , Huber and Mills show why energy is not scarce, why the price of energy doesn\'t matter very much, and why \"waste\" of energy is both necessary and desirable. Across the board, energy isn\'t the problem energy is the solution. Σελίδες: 256, Έτος Έκδοσης: 0425, Διαστάσεις: 20.2x20.2cm

Shortlisted for Best Maths Book of 2022 by Chaulkdust Magazine\'A brilliant account of how models are so often abused and of how they should be used\' John KayHow do mathematical models shape our world - and how can we harness their power for good?Models are at the centre of everything we do. Whether we use them or are simply affected by them, they act as metaphors that help us better understand the increasingly complex problems facing us in the modern world. Without models, we couldn\'t begin to tackle three of the major challenges facing modern society: regulation of the economy, climate change and the COVID-19 pandemic. Yet in recent years, the validity of the models we use has been hotly debated and there has been renewed awareness of the disastrous consequences when the makers and interpreters of models get things wrong.Drawing on contemporary examples from finance, climate and health policy, Erica Thompson explores what models are, why we need them, how they work and what happens when they go wrong. This is not a book that argues we should do away with models, but rather, that we need to properly understand how they are constructed - and how some of the assumptions that underlie the models we use can have significant unintended consequences. Unexpectedly humorous, thought-provoking and passionate, this is essential reading for everyone. Σελίδες: 256, Έτος Έκδοσης: 1124, Διαστάσεις: 15.4x15.4cm

Most of us are clueless when it comes to the physics that makes our modern world so convenient. What\'s the simple science behind motion sensors, touch screens and toasters? How do we enter our offices using touch-on passes or find our way to new places using GPS? In The Physics of Everyday Things, James Kakalios takes us on an amazing journey into the subatomic marvels that underlie so much of what we use and take for granted.Breaking down the world of things into a single day, Kakalios engages our curiosity about how our refrigerators keep food cool, how a plane manages to remain airborne, and how our wrist fitness monitors keep track of our steps. Each explanation is coupled with a story revealing the interplay of the astonishing invisible forces that surround us. Through this \'narrative physics\' The Physics of Everyday Things demonstrates that - far from the abstractions conjured by terms like the Higgs boson, black holes and gravity waves - sophisticated science is also quite practical. With his signature clarity and inventiveness, Kakalios ignites our imaginations and enthralls us with the principles that make up our lives. Σελίδες: 256, Έτος Έκδοσης: 0410, Διαστάσεις: 15.2x15.2cm

A New York Times Science BestsellerWhat if you had to take an art class in which you were only taught how to paint a fence? What if you were never shown the paintings of van Gogh and Picasso, weren\'t even told they existed? Alas, this is how math is taught, and so for most of us it becomes the intellectual equivalent of watching paint dry.In Love and Math , renowned mathematician Edward Frenkel reveals a side of math we\'ve never seen, suffused with all the beauty and elegance of a work of art. In this heartfelt and passionate book, Frenkel shows that mathematics, far from occupying a specialist niche, goes to the heart of all matter, uniting us across cultures, time, and space. Love and Math tells two intertwined stories: of the wonders of mathematics and of one young man\'s journey learning and living it. Having braved a discriminatory educational system to become one of the twenty-first century\'s leading mathematicians, Frenkel now works on one of the biggest ideas to come out of math in the last 50 years: the Langlands Program. Considered by many to be a Grand Unified Theory of mathematics, the Langlands Program enables researchers to translate findings from one field to another so that they can solve problems, such as Fermat\'s last theorem, that had seemed intractable before.At its core, Love and Math is a story about accessing a new way of thinking, which can enrich our lives and empower us to better understand the world and our place in it. It is an invitation to discover the magic hidden universe of mathematics. Σελίδες: 304, Έτος Έκδοσης: 1201, Διαστάσεις: 14.1x14.1cm

\'Exceptionally interesting\' - Alain de Botton\'Fascinating ... You\'ll never again view your own world in quite the same way. A delight to read\' - Ian Stewart\'A book that will transform how you understand human behaviour\' - Thomas EriksonCan physics change your life? It already has.In The Art of Physics, Zahaan Bharmal explains eight ideas from physics that have transformed his view of everyday life and will do the same for you.Far from being abstract, he argues, physics can help us answer very human questions, questions like: Why are some relationships unstable, while others last a lifetime? Why does inequality persist? And why do we all make so many irrational decisions?Drawing on quantum mechanics, thermodynamics, chaos and complexity theory, materials science and more, The Art of Physics reveals the hidden, surprising, and sometimes beautiful ways in which physics can help us to make sense of an unpredictable world. Ultimately, it shows how by embracing the paradoxes and uncertainty at the core of physics, we can unlock a deeper understanding of ourselves and our universe.A deeply personal and thoroughly entertaining tour of life, the universe, and everything.

A Telegraph Best Science Book of the Year“A witty yet in-depth exploration of the prospects for human habitation beyond Earth…Spacefarers is accessible, authoritative, and in the end, inspiring.”—Richard Panek, author of The Trouble with GravityIt’s been over fifty years since Apollo 11 landed on the moon. So why is there so little human presence in space? Will we ever reach Mars? And what will it take to become a multiplanet species? While many books have speculated on the possibility of living beyond the Earth, few have delved into the practical challenges.A wry and compelling take on the who, how, and why of near-future colonies in space, Spacefarers introduces us to the engineers, scientists, planners, dreamers, and entrepreneurs who are striving right now to make life in space a reality. While private companies such as SpaceX are taking the lead and earning profits from human space activity, Christopher Wanjek is convinced this is only the beginning. From bone-whittling microgravity to eye-popping profits, the risks and rewards of space settlement have never been so close at hand. He predicts we will have hotels in low-earth orbit, mining and tourism on the Moon, and science bases on Mars—possibly followed (gravity permitting) by full blown settlements.“Nerdily engaging (and often funny)…Technology and science fiction enthusiasts will find much here to delight them, as Wanjek goes into rich detail on rocketry and propulsion methods, including skyhooks and railguns to fling things into orbit…He is a sensible skeptic, yet also convinced that, in the long run, our destiny is among the stars.”—The Guardian“If the events of this year have had you daydreaming about abandoning the planet entirely, [Spacefarers] is a geekily pleasurable survey of the practicalities and challenges.”—The Telegraph“The best book I’ve read on space exploration since Isaac Asimov.”—Michael Shermer, publisher of Skeptic Σελίδες: 400, Έτος Έκδοσης: 0607, Διαστάσεις: 14x14cm

An Independent Publisher Book Awards Gold Medal WinnerA Progressive Book of the YearA TechCrunch Favorite Read of the Year“Deeply researched and thoughtful.”—Nature“An extended exercise in myth busting.”—Outside“A critique of both popular and scientific understandings of the hormone, and how they have been used to explain, or even defend, inequalities of power.”—The ObserverTestosterone is a familiar villain, a ready culprit for everything from stock market crashes to the overrepresentation of men in prisons. But your testosterone level doesn’t actually predict your appetite for risk, sex drive, or athletic prowess. It isn’t the biological essence of manliness—in fact, it isn’t even a male sex hormone. So what is it, and how did we come to endow it with such superhuman powers?T’s story begins when scientists first went looking for the chemical essence of masculinity. Over time, it provided a handy rationale for countless behaviors—from the boorish to the enviable. Testosterone focuses on what T does in six domains: reproduction, aggression, risk-taking, power, sports, and parenting, addressing heated debates like whether high-testosterone athletes have a natural advantage as well as disagreements over what it means to be a man or woman.“This subtle, important book forces rethinking not just about one particular hormone but about the way the scientific process is embedded in social context.”—Robert M. Sapolsky, author of Behave“A beautifully written and important book. The authors present strong and persuasive arguments that demythologize and defetishize T as a molecule containing quasi-magical properties, or as exclusively related to masculinity and males.”—Los Angeles Review of Books“Provides fruitful ground for understanding what it means to be human, not as isolated physical bodies but as dynamic social beings.”—Science Σελίδες: 288, Έτος Έκδοσης: 0824, Διαστάσεις: 15.6x15.6cm

An exploration of mathematical style through 99 different proofs of the same theoremThis book offers a multifaceted perspective on mathematics by demonstrating 99 different proofs of the same theorem. Each chapter solves an otherwise unremarkable equation in distinct historical, formal, and imaginative styles that range from Medieval, Topological, and Doggerel to Chromatic, Electrostatic, and Psychedelic. With a rare blend of humor and scholarly aplomb, Philip Ording weaves these variations into an accessible and wide-ranging narrative on the nature and practice of mathematics.Inspired by the experiments of the Paris-based writing group known as the Oulipo—whose members included Raymond Queneau, Italo Calvino, and Marcel Duchamp—Ording explores new ways to examine the aesthetic possibilities of mathematical activity. 99 Variations on a Proof is a mathematical take on Queneau’s Exercises in Style, a collection of 99 retellings of the same story, and it draws unexpected connections to everything from mysticism and technology to architecture and sign language. Through diagrams, found material, and other imagery, Ording illustrates the flexibility and creative potential of mathematics despite its reputation for precision and rigor.Readers will gain not only a bird’s-eye view of the discipline and its major branches but also new insights into its historical, philosophical, and cultural nuances. Readers, no matter their level of expertise, will discover in these proofs and accompanying commentary surprising new aspects of the mathematical landscape. Σελίδες: 272, Διαστάσεις: 21.6x21.6cm

“Inspiring and informative…deserves to be widely read.”—Wall Street Journal“This fun book offers a philosophical take on number systems and revels in the beauty of math.”—Science NewsBecause we have ten fingers, grouping by ten seems natural, but twelve would be better for divisibility, and eight is well suited to repeated halving. Grouping by two, as in binary code, has turned out to have its own remarkable advantages.Paul Lockhart presents arithmetic not as rote manipulation of numbers—a practical if mundane branch of knowledge best suited for filling out tax forms—but as a fascinating, sometimes surprising intellectual craft that arises from our desire to add, divide, and multiply important things.

In The End of Science, John Horgan makes the case that the era of truly profound scientific revelations about the universe and our place in it is over. Interviewing scientific luminaries such as Stephen Hawking, Francis Crick, and Richard Dawkins, he demonstrates that all the big questions that can be answered have been answered, as science bumps up against fundamental limits. The world cannot give us a “theory of everything,” and modern endeavors such as string theory are “ironic” and “theological” in nature, not scientific, because they are impossible to confirm. Horgan’s argument was controversial in 1996, and it remains so today, still firing up debates in labs and on the internet, not least because—as Horgan details in a lengthy new introduction—ironic science is more prevalent than ever. Still, while Horgan offers his critique, grounded in the thinking of the world’s leading researchers, he offers homage, too. If science is ending, he maintains, it is only because it has done its work so well. Σελίδες: 368, Έτος Έκδοσης: 0414, Διαστάσεις: 14.1x14.1cm

In Professor Povey\'s Perplexing Problems, Thomas Povey shares 109 of his favourite problems in physics and maths. A tour de force of imagination and exposition, he takes us by the hand and guides us through uncompromisingly challenging territory that expands our minds and encourages a playful and exploratory approach to study. The puzzles, he says, are like toys. We should pick up the one we most enjoy, and play with it.  Whether you are an aspiring scientist or an old-hand, pitting yourself against these problems will test your ability to think, and inspire you with curiosity and enthusiasm for physics. Presented with charm and wit, the questions span the gap between high-school and university-entrance standard material. Detailed answers are lightened with a fascinating and refreshing blend of scientific history, application and personal anecdote. On this delightful and idiosyncratic romp through pre-university maths and physics, the author shows us that behind every single one of these questions lies a new way of thinking about subjects we thought we had understood. He argues that engaging with the unfamiliar is key to forming deeper insights and developing intellectual independence. Professor Povey\'s Perplexing Problems is a manifesto that science should be playful, and a celebration of the curious. Σελίδες: 384, Έτος Έκδοσης: 0801, Διαστάσεις: 15x15cm
