This book and its sequel (Theories of Matter Space and Time: Quantum Theories) are taken from third and fourth year undergraduate Physics courses at Southampton University, UK. The aim of both books is to move beyond the initial courses in classical mechanics, special relativity, electromagnetism, and quantum theory to more sophisticated views of these subjects and their interdependence. The goal is to guide undergraduates through some of the trickier areas of theoretical physics with concise analysis while revealing the key elegance of each subject. The first chapter introduces the key areas of the principle of least action, an alternative treatment of Newtownian dynamics, that provides new understanding of conservation laws. In particular, it shows how the formalism evolved from Fermat's principle of least time in optics. The second introduces special relativity leading quickly to the need and form of four-vectors. It develops four-vectors for all kinematic variables and generalize Newton's second law to the relativistic environment; then returns to the principle of least action for a free relativistic particle. The third chapter presents a review of the integral and differential forms of Maxwell's equations before massaging them to four-vector form so that the Lorentz boost properties of electric and magnetic fields are transparent. Again, it then returns to the action principle to formulate minimal substitution for an electrically charged particle.

This book explores the Local Government Board (LGB) Medical Department's work, successes, and failures throughout its forty-eight-year life and assesses its influence on public health administration in England and Wales. Earlier generations of public health historians have substantially dismissed the Department as being too small to be effective and too lacking in authority to have an impact. More recently a growing number of scholars have challenged this view. This book continues this reappraisal, identifying the influence of the Department on Victorian and Edwardian epidemiology and public health management and its success in protecting Britain from epidemic and endemic infectious disease in a pre-antibiotic era. The Medical Department's small team of doctors provided expertise, encouragement, leadership, and challenge in the management of public health and the struggle against infectious disease in Britain and beyond. Blending a chronological approach with a thematic focus in each chapter to chart the evolution of the LGB Medical Department, the author uses case studies of selected medical inspections to explore the Department's work at various stages in its life. Analysing both national and local archive materials to explore the Medical Department's work and influence in its contemporary contexts, this book offers fresh insights into the relationships between central and local government as well as revealing the significant impact of its expert staff on the development of public health administration in England and Wales.

Not so many years ago most of the cars featured in this book were familiar sights on Britain’s roads. Now, the remaining examples – the ones that weren’t crashed, bashed, thrashed, stolen or scrapped – are reminders of simpler times and simpler technology. During Britain’s spring and summer, thousands of owners polish their cherished motors before driving them to classic car shows and lining them up for inspection by an adoring public. Cars that were once seen so often they blended into the street furniture are now rare enough to rub fenders with the more obvious classics of the age. There are 1.5 million older motors that are still regularly driven around Britain today, and The Classic Car Spotters’ Guide takes you through more than fifty prime examples, from Ford Cortinas and Austin 1100s to Borgward Isabellas and Austin Nash Metropolitans. Complete with rarity ratings and backstories for each one, this book is the perfect companion for your next event.

Petrol stations have been with us for 100 years. They have been built on countless rural and industrial landscapes, often becoming a linchpin of the communities they serve. Men and women in slightly oily overalls would fill up your car’s tank, wipe the windscreen and even check the oil for you. Football coins, Green Shield Stamps, soup bowls or wine glasses might be handed over to keep your custom – all in the days when a single £1 note was enough to buy hundreds of miles of happy motoring. This vivid, illustrated history takes the reader on a journey from collecting a tin can at the local ironmonger’s to filling up on the forecourt, and on to the possibility of not using petrol at all.

Not for the faint-hearted, this rollercoaster scifi thriller for teens and young adults once again pits our heroes, Xalata and Melody, against dark alien forces and the terrors of the unknown. Fresh from their battle with the Cryomorph on the Moon's Farside, Xalata Orbit and Melody Fret had hoped to settle back into a normal routine at the Academy. But strange things have taken place on Mars and when the Red Planet Exploration team arrive back at LunarBase, they bring with them more than their normal cargo. The result for everyone on the Moon is catastrophic, when their lives are threatened by a terrifying attack on the Moon's human population. A seemingly unstoppable alien force transforms its victims into simulants of themselves, building an army of invaders whose purpose is to destroy humankind. Can a weapon be found to defeat them and can two teenage girls and their friends take on the forces of ancient alien science? Can Xalata and Melody survive this second challenge so soon after the first one? Why has Rose Pretty suddenly appeared in two places at once? What dark secret does Penny Wrath hold? How has Frank Wordsmith managed to get onto LunarBase and what are his intentions, now that his plan to destroy Beijing with an asteroid has been foiled? To discover the answers and to live the horror of a stealthy alien attack, read the second in the series, Xalata Orbit and Melody Fret.

Xalata Orbit meets danger head-on when she leaves a troubled Earth behind to live with her father on LunarBase and attend the Hydroponics Institute of the Moon's Central Air Facility. At first, life on the Moon seems dull compared with her home planet, but it is not long before she and her new friend, Melody Fret, are fighting a shadowy enemy for their freedom and battling a conspiracy that could destroy the Earth and all its inhabitants. What horrors are lurking in the derelict Habitat 14 on Farside? Why does the slimy Mr Fark take such an interest in the girls' security? What's the huge secret that Xalata's father carries with him? How can anyone stop an indestructible creature that looks set to destroy the LunarBase? And who are the Asttarians and why do they want to change humans' lives for ever? Xalata Orbit and Melody Fret - The Hammer of Asttar is a science fiction thriller for teenagers and young adults, set in a distant future where disease and terrorism have forced communities to live in secure isolation. The alternative? Populate the planets. But, someone's out to stop people leaving Earth.

This book and its prequel (Theories of Matter, Space, and Time: Classical Theories) grew out of courses that are taught by the authors on the undergraduate degree program in physics at Southampton University, UK. The authors aim to guide the full MPhys undergraduate cohort through some of the trickier areas of theoretical physics that undergraduates are expected to master. To move beyond the initial courses in classical mechanics, special relativity, electromagnetism and quantum theory to more sophisticated views of these subjects and their interdependence. This approach keeps the analysis as concise and physical as possible whilst revealing the key elegance in each subject discussed. This second book of the pair looks at ideas to the arena of Quantum Mechanics. First quickly reviewing the basics of quantum mechanics which should be familiar to the reader from a first course, it then links the Schrodinger equation to the Principle of Least Action introducing Feynman's path integral methods. Next, it presents the relativistic wave equations of Klein, Gordon and Dirac. Finally, Maxwell's equations of electromagnetism are converted to a wave equation for photons and make contact with Quantum Electrodynamics (QED) at a first quantized level. Between the two volumes the authors hope to move a student's understanding from their first courses to a place where they are ready to embark on graduate level courses on quantum field theory.
