More than ever before, radiation is a part of our modern daily lives. We own radiation-emitting phones, regularly get diagnostic x-rays, such as mammograms, and submit to full-body security scans at airports. We worry and debate about the proliferation of nuclear weapons and the safety of nuclear power plants. But how much do we really know about radiation? And what are its actual dangers? An accessible blend of narrative history and science, Strange Glow describes mankind's extraordinary, thorny relationship with radiation, including the hard-won lessons of how radiation helps and harms our health. Timothy Jorgensen explores how our knowledge of and experiences with radiation in the last century can lead us to smarter personal decisions about radiation exposures today. Jorgensen introduces key figures in the story of radiation—from Wilhelm Roentgen, the discoverer of x-rays, and pioneering radioactivity researchers Marie and Pierre Curie, to Thomas Edison and the victims of the recent Fukushima Daiichi nuclear power plant accident. Tracing the most important events in the evolution of radiation, Jorgensen explains exactly what radiation is, how it produces certain health consequences, and how we can protect ourselves from harm. He also considers a range of practical scenarios such as the risks of radon in our basements, radiation levels in the fish we eat, questions about cell-phone use, and radiation's link to cancer. Jorgensen empowers us to make informed choices while offering a clearer understanding of broader societal issues. Investigating radiation's benefits and risks, Strange Glow takes a remarkable look at how, for better or worse, radiation has transformed our society.

An engrossing history of the science of one of the four fundamental physical forces in the universe, electromagnetism, right up to the latest indications that the poles are soon to reverse and destroy the world's power grids and electronic communications A cataclysmic planetary phenomenon is gathering force deep within the Earth. The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades. All agree that it has happened many times before and will happen again. But this time it will be different. It will be a very bad day for modern civilization. Award-winning science journalist Alanna Mitchell's delightful storytelling introduces enchanting characters from investigations into magnetism in thirteenth-century France to the discovery in the Victorian era that electricity and magnetism emerge from the same force. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles dramatically, catastrophically reverse now and then... The recent finding that Earth's magnetic force field is decaying faster than previously thought, raising fears of an imminent pole reversal, ultimately gives The Spinning Magnet a spine-tingling urgency. When the poles switch, a process that takes many years, Earth is unprotected from solar radiation storms that would, among other things, wipe out all electromagnetic technology. No satellites, no Internet, no smartphones--maybe no power grid at all. Alanna Mitchell offers a beautifully crafted narrative history of ideas and science that readers of Stephen Greenblatt and Sam Kean will love.

In Teaching Creative Thinking: Developing Learners Who Generate Ideas and Can Think Critically, Bill Lucas and Ellen Spencer define and demystify the essence of creative thinking, and offer action-oriented and research-informed suggestions as to how it can best be developed in learners. Where once it was enough to know and do things, young people now need more than subject knowledge in order to thrive: they need capabilities. Teaching Creative Thinking is the first title in the three-part Pedagogy for a Changing World series, founded upon Lucas and Spencer’s philosophy of dispositional teaching – a pedagogical approach which aims to cultivate in learners certain dispositions that evidence suggests are going to be valuable to them both at school and in later life. A key capability is creative thinking, and, in 2021, one of the guardians of global comparative standards, PISA, is recognising its importance by making creative thinking the ‘innovative assessment domain’ to supplement their testing of 15-year-olds’ core capabilities in English, maths and science. Creative thinkers are inquisitive, collaborative, imaginative, persistent and disciplined – and schools which foster these habits of mind in learners need to be creative in engaging children and young people by embedding creativity into their everyday educational experiences. In this extensive enquiry into the nature and nurture of creative thinking, the authors explore the effectiveness of various pedagogical approaches – including problem-based learning, growth mindset, playful experimentation and the classroom as a learning community – and provide a wealth of tried-and-tested classroom strategies that will boost learners’ critical and creative thinking skills. The book is structured in an easy-to-access format, combining a comprehensive listing of practical ideas to stimulate lesson planning with expert guidance on integrating them into your practice, followed by plenty of inventive suggestions as to how learners’ progress can be assessed and tracked along the way – by both the pupil and the teacher. The authors then go further to offer exemplars of success by presenting case studies of schools’ innovations in adopting these approaches, and dedicate a chapter to dispelling any pressing doubts that teachers may have by exposing the potential pitfalls and offering advice on how to avoid them. Venturing beyond the classroom setting, Teaching Creative Thinking also delves into the ways in which a school can work towards the provision of co-curricular experiences – such as partnering with a range of external community groups – and better engage its leadership team and pupils’ parents with the idea of creative thinking in order to support learners with opportunities to grow. The authors offer many examples which will inspire schools to do just this, and collate these ideas into building a framework for learning that equips young people in schools today with the twenty-first century skills and capabilities that will enable them to thrive in the workforce of tomorrow. Replete with research-led insight and ready-to-use strategies, Teaching Creative Thinking is a powerful call to action and a practical handbook for all teachers and leaders, in both primary and secondary settings, who want to embed a capabilities approach in their schools. Contents include: Series Introduction – Capabilities and Pedagogy; Chapter 1 – Creative Thinking; Chapter 2 – Cultivating Creative Thinkers; Chapter 3 – Getting Going; Chapter 4 – Going Deeper; Chapter 5 – Promising Practices; Chapter 6 – Signs of Success; Chapter 7 – Creative Challenges.

Although group theory is a mathematical subject, it is indispensable to many areas of modern theoretical physics, from atomic physics to condensed matter physics, particle physics to string theory. In particular, it is essential for an understanding of the fundamental forces. Yet until now, what has been missing is a modern, accessible, and self-contained textbook on the subject written especially for physicists. Group Theory in a Nutshell for Physicists fills this gap, providing a user-friendly and classroom-tested text that focuses on those aspects of group theory physicists most need to know. From the basic intuitive notion of a group, A. Zee takes readers all the way up to how theories based on gauge groups could unify three of the four fundamental forces. He also includes a concise review of the linear algebra needed for group theory, making the book ideal for self-study. Provides physicists with a modern and accessible introduction to group theory Covers applications to various areas of physics, including field theory, particle physics, relativity, and much more Topics include finite group and character tables; real, pseudoreal, and complex representations; Weyl, Dirac, and Majorana equations; the expanding universe and group theory; grand unification; and much more The essential textbook for students and an invaluable resource for researchers Features a brief, self-contained treatment of linear algebra An online illustration package is available to professors Solutions manual (available only to professors)

Long before the hydrogen bomb indelibly associated radioactivity with death, many chemists, physicists, botanists, and geneticists were excited thinking that radium held the key to the secret of life. Luis Campos examines the many and varied connections between early radioactivity research and understandings of vitality, both scientific and popular, in the first half of the twentieth century. As some physicists and chemists early on described the wondrous new element and its radioactive brethren in lifelike terms ( decay, half-life, and frequent reference to the natural selection and evolution of the elements), many biologists of the period eagerly sought to bring radium into the biological fold. They did so with experiments aimed at elucidating some of the most basic phenomena of life, including metabolism and mutation, and often saw in these phenomena properties that in turn reminded them of the new element. These initially provocative links between radium and life proved remarkably productive in experimental terms and ultimately led to key biological insights into the origin of life, the nature of mutation, and the structure of the gene. "Radium and the Secret of Life" traces the half-life of this connection between the living and the radioactive, while also exploring the approach to history that emerges when one follows a trail of associations that, asymptotically, never quite disappears."
