What is 'nothing'? What remains when you take all the matter away? Can empty space - a void - exist? This Very Short Introduction explores the science and the history of the elusive void: from Aristotle who insisted that the vacuum was impossible, via the theories of Newton and Einstein, to our very latest discoveries and why they can tell us extraordinary things about the cosmos. Frank Close tells the story of how scientists have explored the elusive void, and the rich discoveries that they have made there. He takes the reader on a lively and accessible history through ancient ideas and cultural superstitions to the frontiers of current research. He describes how scientists discovered that the vacuum is filled with fields; how Newton, Mach, and Einstein grappled with the nature of space and time; and how the mysterious 'aether' that was long ago supposed to permeate the void may now be making a comeback with the latest research into the 'Higgs field'. We now know that the vacuum is far from being empty - it seethes with virtual particles and antiparticles that erupt spontaneously into being, and it also may contain hidden dimensions that we were previously unaware of. These new discoveries may provide answers to some of cosmology's most fundamental questions: what lies outside the universe, and, if there was once nothing, then how did the universe begin?

Very Short Introductions: Brilliant, Sharp, Inspiring Following the discovery of the Higgs boson, Frank Close has produced this major revision to his classic and compelling introduction to the fundamental particles that make up the universe. Frank Close takes us on a journey into the atom to examine known particles such as quarks, electrons, and the ghostly neutrino, and explains the key role and significance of the Higgs boson. Along the way he provides fascinating insights into how discoveries in particle physics have actually been made, and discusses how our picture of the world has been radically revised in the light of these developments. He concludes by looking ahead to new ideas about the mystery of antimatter and massive neutrinos, and to what the next 50 years of research might reveal about the nature of the Higgs field which moulds the fundamental particles and forces.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

Nuclear physics began long before the identification of fundamental particles, with J. J. Thomson's discovery of the electron at the end of the 19th century, which implied the existence of a positive charge in the atom to make it neutral. In this Very Short Introduction Frank Close gives an account of how this area of physics has progressed, including the recognition of how heavy nuclei are built up in the cores of stars and in supernovae, the identification of quarks and gluons, and the development of quantum chromodynamics (QCD). Exploring key concepts such as the stability of different configurations of protons and neutrons in nuclei, Frank Close shows how nuclear physics brings the physics of the stars to Earth and provides us with important applications, particularly in medicine.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

'Everything about this story is astounding' Bryan Appleyard, Sunday Times"Trinity" was the codename for the test explosion of the atomic bomb in New Mexico on 16 July 1945. Trinity is now also the extraordinary story of the bomb's metaphorical father, Rudolf Peierls; his intellectual son, the atomic spy, Klaus Fuchs, and the ghosts of the security services in Britain, the USA and USSR.Against the background of pre-war Nazi Germany, the Second World War and the following Cold War, the book traces how Peierls brought Fuchs into his family and his laboratory, only to be betrayed. It describes in unprecedented detail how Fuchs became a spy, his motivations and the information he passed to his Soviet contacts, both in the UK and after he went with Peierls to join the Manhattan Project at Los Alamos in 1944. Frank Close is himself a distinguished nuclear physicist: uniquely, the book explains the science as well as the spying.Fuchs returned to Britain in August 1946 still undetected and became central to the UK's independent effort to develop nuclear weapons. Close describes the febrile atmosphere at Harwell, the nuclear physics laboratory near Oxford, where many of the key players were quartered, and the charged relationships which developed there. He uncovers fresh evidence about the role of the crucial VENONA signals decryptions, and shows how, despite mistakes made by both MI5 and the FBI, the net gradually closed around Fuchs, building an intolerable pressure which finally cracked him.The Soviet Union exploded its first nuclear device in August 1949, far earlier than the US or UK expected. In 1951, the US Congressional Committee on Atomic Espionage concluded, 'Fuchs alone has influenced the safety of more people and accomplished greater damage than any other spy not only in the history of the United States, but in the history of nations'. This book is the most comprehensive account yet published of these events, and of the tragic figure at their centre.

The story of the Higgs boson - the so-called 'God particle' - and the man who thought of itIn the summer of 1964, a reclusive young professor at the University of Edinburgh wrote two scientific papers which have come to change our understanding of the most fundamental building blocks of matter and the nature of the universe. Peter Higgs posited the existence an almost infinitely tiny particle - today known as the Higgs boson - which is the key to understanding why particles have mass, and but for which atoms and molecules could not exist.For nearly 50 years afterwards, some of the largest projects in experimental physics sought to demonstrate the physical existence of the boson which Higgs had proposed. Sensationally, confirmation came in July 2012 at the Large Hadron Collider at CERN in Geneva. The following year Higgs was awarded the Nobel Prize for Physics. One of the least-known giants of science, he is the only person in history to have had a single particle named for them.This revelatory book is 'not so much a biography of the man but of the boson named after him'. It brilliantly traces the course of much of twentieth-century physics from the inception of quantum field theory to the completion of the 'standard model' of particles and forces, and the pivotal role of Higgs's idea in this evolution. It also investigates the contested history of Higgs's responsibility for the breakthrough when there were others close by, and explains why the boson is named for him alone. Competition between institutions and states, Close shows, then played as much of a role in creating Higgs's fame as his work itself. Drawing on conversations with Higgs over a decade (a figure generally as elusive as his particle) this is a superb study of a scientist and his era - and of how scientific knowledge advances.

"Have you ever seen a total solar eclipse?" If the question caused you to search your memory, the correct answer would have been "no." A common response is: "Yes--I saw one, it was about 90% partial eclipse where I lived." A 90% partial eclipse is indeed a remarkable phenomenon, but true totality leaves all else in the shade, in all senses of the phrase. Ask the question of anyone who has experienced the full sensation of being obliterated by the moon's shadow, and they will reply "yes"--without hesitation--and continue with a monologue describing the overwhelming experiences and unique phenomena that ensued.On 21 August 2017 millions of people across the United States witnessed "The Great American Eclipse" of the Sun. The moment it was over, people around the world were asking questions: what caused the weird shadows and colors in the build up to totality? Were those ephemeral bands of shadows gliding across the ground in the seconds before totality real or an optical illusion? Why this, what that, but above all: where and when can I see a total solar eclipse again?Eclipses: What Everyone Needs to Know helps explain the profound differences between a 99.99% partial eclipse and true totality, and inform readers how to experience this most beautiful natural phenomenon successfully. It covers eclipses of sun, moon, and other astronomical objects, and their applications in science, as well as their role in history, literature, and myth. It describes the phenomena to expect at a solar eclipse and the best ways to record them--by camera, video, or by simple handmade experiments. The book covers the timetable of upcoming eclipses, where the best locations will be to see them, and the opportunities for using them as vehicles for inspiration and education. As a veteran of seven total solar eclipses, physicist Frank Close is an expert both on the theory and practice of eclipses. Eclipses: What Everyone Needs to Know is a popular source of information on the physics of eclipses.

On 21 August 2017, over 100 million people will gather in a narrow belt across the USA to witness the most watched total solar eclipse in history. Eclipse - Journeys to the Dark Side of the Moon, written by the widely read popular science author Frank Close, describes the spellbinding allure of this most beautiful natural phenomenon. The book explains why eclipses happen, reveals their role in history, literature and myth, and focuses on eclipse chasers, who travel with ecstatic fervour to some of the most inaccessible places on the globe to be present at the moment of totality. The book includes the author's quest to solve a 3000 years old mystery: how did the moon move backwards during a total solar eclipse, as claimed in the Book of Joshua?It is an inspirational tale: how a teacher and an eclipse inspired the author, aged eight, to a life in science, and a love affair with eclipses, which takes him to a war zone in the Western Sahara, to the South Pacific and the African bush. The tale comes full circle with another eight-year old boy - the author's grandson - at the 2017 great American eclipse. Readers of all ages will be drawn to this inspirational chronicle of the mesmerizing experience of total solar eclipse.

Antimatter explores a strange mirror world, where particles have identical yet opposite properties to those that make up the familiar matter we encounter everyday; where left becomes right, positive becomes negative; and where, should matter and antimatter meet, the two annihilate in a blinding flash of energy that makes even thermonuclear explosions look feeble by comparison. It is an idea long beloved of science-fiction stories--but here, renowned science writer Frank Close shows that the reality of antimatter is even more fascinating than the fiction itself. We know that once, antimatter and matter existed in perfect counterbalance, and that antimatter then perpetrated a vanishing act on a cosmic scale that remains one of the greatest mysteries of the universe. Today, antimatter does not exist normally, at least on Earth, but we know that it is real for scientists are now able to make small pieces of it in particle accelerators, such as that at CERN in Geneva. Looking at the remarkable prediction of antimatter and how it grew from the meeting point of relativity and quantum theory in the early 20th century, at the discovery of the first antiparticles, at cosmic rays, annihilation, antimatter bombs, and antiworlds, Close separates the facts from the fiction about antimatter, and explains how its existence can give us profound clues about the origins and structure of the universe.Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.

We are living in a Golden Age of Physics. Forty or so years ago, three brilliant, yet little-known scientists - an American, a Dutchman, and an Englishman - made breakthroughs which later inspired the construction of the Large Hadron Collider at CERN in Geneva: a 27 kilometre-long machine that cost ten billion dollars, took twenty years to build, and finally discovered a particle consistent with the Higgs boson. The Infinity Puzzle is the inside story of those forty years of research, breakthrough, and endeavour. Peter Higgs, Gerard 't Hooft and James Bjorken were the three scientists whose work is explored here, played out across the decades against a backdrop of high politics, low behaviour, and billion dollar budgets. Written by Frank Close, the eminent physicist and award-winning writer, The Infinity Puzzle also draws upon the author's close friendships with those involved. In July 2012, in the days leading up to the momentous announcement that the Higgs boson had indeed been discovered, Frank Close and Peter Higgs were together at a conference in Sicily. In this paperback edition, Close includes a substantial epilogue reflecting on the announcement, its implications, and the impact on Peter Higgs and others.

What are neutrinos? Why does nature need them? What use are they?Neutrinos are perhaps the most enigmatic particles in the universe. Formed in certain radioactive decays, they pass through most matter with ease. These tiny, ghostly particles are formed in millions in the Sun and pass through us constantly. For a long time they were thought to be massless, and passing as they do like ghosts they were not regarded as significant. Now we know they have a very small mass, and there are strong indications that they are very important indeed. It is speculated that a heavy form of neutrino, that is both matter and antimatter, may have shaped the balance of matter and antimatter in the early universe. Here, Frank Close gives an account of the discovery of neutrinos and our growing understanding of their significance, also touching on some speculative ideas concerning the possible uses of neutrinos and their role in the early universe.

Henry Becquerel’s accidental discovery, in Paris in 1896, of a faint smudge on a photographic plate sparked a chain of discoveries which would unleash the atomic age.Destroyer of Worlds is the story of how pursuit of this hidden source of nuclear power, which began innocently and collaboratively, was overwhelmed by the politics of the 1930s, and following devastation of Hiroshima and Nagasaki opened the way to a still more terrible possibility: a thermonuclear bomb, the so-called “backyard weapon”, that could destroy all life on earth – from anywhere.The story spans decades and continents, moving from Becquerel to Ernest Rutherford, the Cambridge-based, New Zealand scientist who first split the atom, expands to include Enrico Fermi in Rome, Otto Hahn and Lise Meitner in Berlin and the Joliot-Curies in Paris, leading to the appearance of Robert Oppenheimer before climaxing with increasingly horrifying developments in the USA and USSR. The roles of three remarkable women – Lise Meitner, Ida Noddack and Irene Curie – are re-evaluated, and there are new insights into the work of Ettore Majorana, Fermi’s mercurial but brilliant assistant, who mysteriously disappeared in 1938, possibly after foreseeing the explosive power of nuclear energy. Above all, this is a story of how knowledge is often advanced by personal convictions and relationships, an indeed by chance, in a remarkable way.

Speculation is rife that by 2012 the elusive Higgs boson will be found at the Large Hadron Collider. If found, the Higgs boson would help explain why everything has mass. But there's more at stake,what we're really testing is our capacity to make the universe reasonable. Our best understanding of physics is predicated on something known as quantum field theory. Unfortunately, in its raw form, it doesn't make sense,its outputs are physically impossible infinite percentages when they should be something simpler, like the number 1. The kind of physics that the Higgs boson represents seeks to renormalize" field theory, forcing equations to provide answers that match what we see in the real world. The Infinity Puzzle is the story of a wild idea on the road to acceptance. Only Close can tell it.

This book tells the remarkable lives of the pioneers of science – from Galileo and Newton, Faraday and Darwin, Pasteur and Marie Curie, to Einstein, Freud, Turing, and Crick and Watson.

The memo landed on Kim Philby's desk in Washington, DC, in July 1950. Three months later, Bruno Pontecorvo, a physicist at Harwell, Britain's atomic energy lab, disappeared without a trace. When he re-surfaced six years later, he was on the other side of the Iron Curtain.One of the most brilliant scientists of his generation, Pontecorvo was privy to many secrets: he had worked on the Anglo-Canadian arm of the Manhattan Project, and quietly discovered a way to find the uranium coveted by nuclear powers. Yet when he disappeared MI5 insisted he was not a threat. Now, based on unprecedented access to archives, letters, surviving family members and scientists, award-winning writer and physics professor Frank Close exposes the truth about a man irrevocably marked by the advent of the atomic age and the Cold War.

Allgegenwärtig und unsichtbar, fast masselos und voller Geheimnisse – Frank Close erzählt die faszinierende Geschichte der Neutrinos„Wo waren Sie am Morgen des 23. Februar 1987 um 8:30 Uhr? Ich saß gerade beim Frühstück, als ein Neutrinoschauer durch meine Cornflakes raste, ohne dass ich das Geringste davon merkte.“Sie sind Meister der Tarnung und Verwandlung – jene „Geisterteilchen“, die uns und die Erde durchdringen, als seien wir Nichts, und über die der Physiker Wolfgang Pauli einst bemerkte: „Heute habe ich etwas Schreckliches getan, etwas, was kein theoretischer Physiker jemals tun sollte. Ich habe etwas vorgeschlagen, was nie experimentell verifiziert werden kann.“ Es brauchte lange Jahre, viel Geduld und großen Einfallsreichtum, um einen indirekten, flüchtigen Blick auf das schwer fassbare Neutrino zu erhaschen und jene Kiste Champagner zu gewinnen, die Pauli auf dessen Entdeckung gewettet hatte. Hier ist die Geschichte, wie jenes außergewöhnlichste aller Teilchen – ladungslos, (fast so) schnell wie das Licht, nur selten mit Materie interagierend – gesucht und gefunden wurde, welche Forscher maßgeblichen Anteil daran hatten und wie uns heute die Neutrinoastronomie tiefe Einblicke in die Herzen ferner Galaxien ermöglicht._____Neutrinos spielen in unserem Universum die Rolle grauer Eminenzen, die kaum in Erscheinung treten. Sie sind so „scheu“, dass es eigentlich erstaunlich ist, dass wir überhaupt von ihrer Existenz wissen. Wie haben sich diese geisterhaften, unsichtbaren Stücke Nichts überhaupt zu erkennen gegeben? Wozu braucht sie die Natur? Wozu sind sie da?Jene außergewöhnlichen Partikel sind zum einen Überreste des Urknalls, zum anderen werden sie fortwährend in der Sonne und anderen Sternen erzeugt. Durch die Erde strömen sie zu Billionen, fast ungehindert und ohne Unterlass. Wie Frank Close es ausdrückt: „Hätten wir Augen fürNeutrinos, wäre die Nacht genauso hell wie der Tag. Die Sonnenneutrinos ‚beleuchten‘ uns tags von oben und nachts – durch die Erde und unsere Betten hindurch – von unten.“ Der Autor schildert in seinem spannenden kleinen Buch nicht nur die ersten theoretischen Hinweise auf die Existenz eines solchen Teilchens, sondern auch den langen Kampf, jene Neutrinos zu „fangen“ und ihre Natur zu verstehen.An der Geschichte ihrer Entdeckung waren nicht nur eine Vielzahl unterschiedlicher Charaktere beteiligt, sondern auch tonnenweise Spülmittel in Tanks in Minen tief unter der Erde. So winzig Neutrinos auch sein mögen, sie tragen Informationen aus der Tiefe ferner Sterne und Galaxien. Und sie haben einen ganzen Zweig der Astronomie begründet, der es uns nicht zuletzt erlaubt, die frühen Momente des Universums selbst zu erforschen.
