Quantum physicist, New York Times bestselling author, and BBC host Jim Al-Khalili reveals how 8 lessons from the heart of science can help you get the most out of life Today's world is unpredictable and full of contradictions, and navigating its complexities while trying to make the best decisions is far from easy. The Joy of Science presents 8 short lessons on how to unlock the clarity, empowerment, and joy of thinking and living a little more scientifically. In this brief guide to leading a more rational life, acclaimed physicist Jim Al-Khalili invites readers to engage with the world as scientists have been trained to do. The scientific method has served humankind well in its quest to see things as they really are, and underpinning the scientific method are core principles that can help us all navigate modern life more confidently. Discussing the nature of truth and uncertainty, the role of doubt, the pros and cons of simplification, the value of guarding against bias, the importance of evidence-based thinking, and more, Al-Khalili shows how the powerful ideas at the heart of the scientific method are deeply relevant to the complicated times we live in and the difficult choices we make. Read this book and discover the joy of science. It will empower you to think more objectively, see through the fog of your own preexisting beliefs, and lead a more fulfilling life.
While neutron halos were discovered 30 years ago, this is the first book written on the subject of this exotic form of nuclei that typically contain many more neutrons than stable isotopes of those elements. It provides an introductory description of the halo and outlines the discovery and evidence for its existence. It also discusses different theoretical models of the halo's structure as well as models and techniques in reaction theory that have allowed us to study the halo. This is written at a level accessible to graduate students starting a PhD in nuclear physics. Halo nuclei are an exotic form of atomic nuclei that contain typically many more neutrons than stable isotopes of those elements. To give you a famous example, an atom of the element lithium has three electrons orbiting a nucleus with three protons and, usually, either 3 or 4 neutrons. The difference in the number of neutrons gives us two different isotopes of lithium, Li6 and Li7. But if you keep adding neutrons to the nucleus you will eventually reach Li11, with still 3 protons (that means it's lithium) but with 8 neutrons. This nucleus is so neutron-rich that the last two are very weakly bound to the rest of the nucleus (a Li9 core). What happens is a quantum mechanical effect: the two outer neutrons float around beyond the rest of the nuclear core at a distance that is beyond the range of the force that is holding them to the core. This is utterly counterintuitive. It means the nucleus looks like a core plus extended diffuse cloud of neutron probability: the halo. The author of the book, Jim Al-Khalili, is a theoretician who published some of the key papers on the structure of the halo in the mid and late 90s and was the first to determine its true size. This monograph is based on review articles he has written on the mathematical models used to determine the halo structure and the reactions used to model that structure.
Quantum physicist, New York Times bestselling author, and BBC host Jim Al-Khalili offers a fascinating and illuminating look at what physics reveals about the world Shining a light on the most profound insights revealed by modern physics, Jim Al-Khalili invites us all to understand what this crucially important science tells us about the universe and the nature of reality itself. Al-Khalili begins by introducing the fundamental concepts of space, time, energy, and matter, and then describes the three pillars of modern physics-quantum theory, relativity, and thermodynamics-showing how all three must come together if we are ever to have a full understanding of reality. Using wonderful examples and thought-provoking analogies, Al-Khalili illuminates the physics of the extreme cosmic and quantum scales, the speculative frontiers of the field, and the physics that underpins our everyday experiences and technologies, bringing the reader up to speed with the biggest ideas in physics in just a few sittings. Physics is revealed as an intrepid human quest for ever more foundational principles that accurately explain the natural world we see around us, an undertaking guided by core values such as honesty and doubt. The knowledge discovered by physics both empowers and humbles us, and still, physics continues to delve valiantly into the unknown. Making even the most enigmatic scientific ideas accessible and captivating, this deeply insightful book illuminates why physics matters to everyone and calls one and all to share in the profound adventure of seeking truth in the world around us.
Die Quantenphysik ist, fast 100 Jahre nach Ihrer Entstehung, immer noch eine Wissenschaft zum Staunen - eine fundamental neue Sicht in Wissenschaft und Technik, die immer noch schockiert oder zumindest unverstAndlich bleibt. Aber ist die Welt der Quanten wirklich so befremdlich wie ihr Ruf? Und lAsst sich das Paradox der SchrAdingerschen Katze, deren Quantenzustand eine Mischung aus tot und lebendig zu sein scheint, lAsen? Quantum lAdt den Leser zu einer Reise in die Quantenwelt ein und beginnt dort, wo auch die Physiker die erste fundamentale Aoeberraschung erlebten: beim Doppelspaltexperiment. Es sieht einfach aus - atomare Teilchen treffen wie MiniaturbAlle auf ein Hindernis mit zwei Durchlassspalten, aber es hat es in sich. Denn anders als BAlle, die entweder durch einen oder durch den anderen Spalt fliegen, verhalten sich Atome wie Wellen, die hinter zwei Spalten ein Aoeberlagerungsmuster bilden. Dieses Interferenzmuster bedeutet quantenphysikalisch, dass einzelne Teilchen durch beide Spalte getreten sind - wie eine Welle, die an beiden Spalten durchgelassen wird und dann zwei sich A1/4berlagernde Komponenten aufweist. Aber wie kann ein einzelnes Atom an den zwei Orten der beiden Spalte gleichzeitig erscheinen? Heisenbergs UnschArferelation und SchrAdingers Katze sind nur der Anfang zu einer spannenden und anschaulichen Reise mit bildlichen EindrA1/4cken von Quantengenen, Quantencomputern und VerschrAnkungen von QuantenzustAnden, die wie wie Science-Fiction anmuten, wenn fA1/4r Lichtquanten einfach mal herA1/4bergebeamt werden kAnnen.

Jim Al-Khalili is about to untangle the world's greatest science conundrums... ___________ How does the fact that it gets dark at night prove the Universe must have started with a big bang? Where are all the aliens? Why does the length of a piece of string vary depending on how fast it is moving? Our subject is 'perceived paradoxes' - questions or thought-experiments that on first encounter seem impossible to answer, but which science has been able to solve. Our tour of these mind-expanding puzzles will take us through some of the greatest hits of science - from Einstein's theories about space and time, to the latest ideas of how the quantum world works. Some of our paradoxes may be familiar, such as Schroedinger's famous cat, which is seemingly alive and dead at the same time; or the Grandfather Paradox - if you travelled back in time and killed your grandfather you would not have been born and would not therefore have killed your grandfather. Other paradoxes will be new to you, but no less bizarre and fascinating. In resolving our paradoxes we will have to travel to the furthest reaches of the Universe and explore the very essence of space and time. Hold on tight.

Do Aliens Exist? And if they do - what would they look like? Where would they live? Would they be conscious beings? And what would happen if they found us? These are the biggest questions we've ever asked - and here, Professor Jim Al-Khalili, theoretical physicist and host of BBC Radio Four's The Life Scientific, blasts off in search of answers. Coming with him are Martin Rees, Ian Stewart, Louisa Preston, Monica Grady, Sara Seager, Paul Davies and a crack team of scientists and experts who've made it their life's work to discover the truth. So get ready to visit the ice boulders and hydrocarbon lakes of Saturn's moon Titan, meet the tiny eight-legged critters that could survive in space, and learn about the neuroscience behind belief in alien abductions. Along the way, you'll enter the mind of an octopus, work out the probability of us finding an alien civilisation and discover whether quantum computing might hold the secret to life itself. Lively, curious and filled with scientific insights fresh from the cutting edge of the Galaxy, Aliens is the perfect book for anyone who has ever looked up into the starry sky and wondered: are we alone?
Life is the most extraordinary phenomenon in the known universe; but how does it work? Even in this age of cloning and synthetic biology, the remarkable truth remains: nobody has ever made anything living entirely out of dead material. Life remains the only way to make life. Are we missing a vital ingredient in its creation? Like Richard Dawkins' The Selfish Gene, which provided a new perspective on evolution, Life on the Edge alters our understanding of life's dynamics as Jim Al-Khalili and Johnjoe Macfadden reveal the hitherto missing ingredient to be quantum mechanics. Drawing on recent ground-breaking experiments around the world, they show how photosynthesis relies on subatomic particles existing in many places at once, while inside enzymes, those workhorses of life that make every molecule within our cells, particles vanish from one point in space and instantly materialize in another. Each chapter in Life on the Edge opens with an engaging example that illustrates one of life's puzzles - How do migrating birds know where to go? How do we really smell the scent of a rose? How do our genes manage to copy themselves with such precision? - and then reveals how quantum mechanics delivers its answer. Guiding the reader through the maze of rapidly unfolding discovery, Al-Khalili and McFadden communicate vividly the excitement of this explosive new field of quantum biology, with its potentially revolutionary applications, and also offer insights into the biggest puzzle of all: what is life?
In Pathfinders: The Golden Age of Arabic Science, Jim al-Khalili celebrates the forgotten pioneers who helped shape our understanding of the world. For over 700 years the international language of science was Arabic. Surveying the golden age of Arabic science, Jim Al-Khalili reintroduces such figures as the Iraqi physicist Ibn al-Haytham, who practised the modern scientific method over half a century before Bacon; al-Khwarizmi, the greatest mathematician of the medieval world; and Abu Rayhan al-Biruni, a Persian polymath to rival Leonardo da Vinci. 'Jim Al-Khalili has a passion for bringing to a wider audience not just the facts of science but its history ... Just as the legacy of Copernicus and Darwin belongs to all of us, so does that of Ibn Sina and Ibn al-Haytham' Independent 'He has brought a great story out of the shadows' Literary Review 'His command of Arabic and mathematical physics invests his story with sympathy as well as authority' Guardian 'A fascinating and user-friendly guide' Sunday Telegraph 'This captivating book is a timely reminder of the debt owed by the West to the intellectual achievements of Arab, Persian and Muslim scholars' The Times Jim Al-Khalili OBE is Professor of Physics at the University of Surrey, where he also holds the first Surrey chair in the public engagement in science. He was awarded the Royal Society Michael Faraday Prize for science communication in 2007, elected Honorary Fellow of the British Association for the Advancement of Science and has also received the Institute of Physic's Public Awareness of Physics Award. Born in Baghdad, Jim was educated in Iraq until the age of 16 and it was there, being taught by Arabic teachers in Arabic that he first heard and learnt about the great Arab scientists and philosophers.

'Excellent, exactly how good science fiction should be: gripping story, beautifully told, while at the same time being scientifically well-informed.' tweeted RICHARD DAWKINS. 'Reminiscent of vintage Arthur C. Clarke . . . has a chilling, nail-biting authenticity' said JAMES LOVEGROVE in the Financial Times. From renowned theoretical physicist, broadcaster and author Jim Al-Khalili, comes this thrilling debut novel drawing on cutting-edge science and set in a near-future full of dazzling technologies. 2041 and the world as we know it grinds to a halt. Our planet seems to be turning against itself - it would appear that the magnetic field, that protects life on Earth from deadly radiation from space, is failing . . . Desperate to quell the mass hysteria that would surely follow, world governments have concealed this rapidly emerging Armageddon. But a young Iranian hacktivist stumbles across the truth, and it becomes a race against time to reactivate the earth's core using beams of dark matter. As a small team of brave and brilliant scientists battle to find a way of transforming theory into practice, they face a fanatical group intent on pursuing their own endgame agenda: for they believe mankind to be a plague upon this earth and will do anything, commit any crime, to ensure that the project fails . . . And so bring about humanity's end.
A myth-shattering view of the Islamic world's myriad scientific innovations and the role they played in sparking the European Renaissance. Many of the innovations that we think of as hallmarks of Western science had their roots in the Arab world of the middle ages, a period when much of Western Christendom lay in intellectual darkness. Jim al- Khalili, a leading British-Iraqi physicist, resurrects this lost chapter of history, and given current East-West tensions, his book could not be timelier. With transporting detail, al-Khalili places readers in the hothouses of the Arabic Enlightenment, shows how they led to Europe's cultural awakening, and poses the question: Why did the Islamic world enter its own dark age after such a dazzling flowering?

Riddled with jealousy, rivalry, missed opportunities and moments of genius, the history of the atom's discovery is as bizarre, as capricious, and as weird as the atom itself. John Dalton gave us the first picture of the atom in the early 1800s. Almost 100 years later the young misfit New Zealander, Ernest Rutherford, showed the atom consisted mostly of space, and in doing so overturned centuries of classical science. It was a brilliant Dane, Neils Bohr, who made the next great leap - into the incredible world of quantum theory. Yet, he and a handful of other revolutionary young scientists weren't prepared for the shocks Nature had up her sleeve. This 'insightful, compelling' book (New Scientist) reveals the mind-bending discoveries that were destined to upset everything we thought we knew about reality and unleash a dangerous new force upon the world. Even today, as we peer deeper and deeper into the atom, it throws back as many questions at us as answers.
Thought the science of the future was all hoverboards and space travel? Think again. Every day, scientists come up with the ingenious solutions and surprising discoveries that will define our future. So here, Jim Al-Khalili and his crack team of experts bin the crystal ball and use cutting-edge science to get a glimpse of what's in store. From whether teleportation is really possible (spoiler: it is), to what we'll do if artificial intelligence takes over, What's Next? takes on the big questions. And along the way, it'll answer questions like: Will we find a cure to all diseases? An answer to climate change? Will bionics make us into superheroes? Touching on everything from genetics to transport, and nanotechnology to teleportation, What's Next? is a fascinating, fun and informative look at what's in store for the human race.
A fun and fascinating look at great scientific paradoxes.
