Download or read book Radioactivity written by Claudio Tuniz and published by OUP Oxford. This book was released on 2012-07-26 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: You cannot hide from radioactivity. Even the book you are holding is slightly radioactive, but there are more serious risks. Radioactivity - the breakdown of unstable atomic nuclei, releasing radiation - is a fundamental process in nature. It is a process that has been harnessed to provide wide and important applications in science, medicine, industry, and energy production. But it remains much misunderstood - and feared, perhaps because nuclear radiation cannot be detected by human senses, and can undoubtedly do great harm if appropriate precautions are not taken. In recent times there have been increasing concerns about nuclear terrorism. The traces of radioactive atoms in rocks have allowed us to understand the nature and history of the Earth, in particular to date events in that history. Radioactive dating has been used for a variety of purposes, from determining the age of the first hominids to the dating of the Turin Shroud. The discovery of radioactivity has improved our survival kit, but also gave us the chance to reach a new level of awareness on the history of our species and its environmental impacts. In this Very Short Introduction, Claudio Tuniz explains the nature of radioactivity and discuss its role in nature. Describing radioactivity in the stars and in the Earth, he also looks at its wide range of applications in biomedicine and in science, as well as the mechanisms of nuclear fission and fusion, and the harnessing of nuclear power.

Download or read book Anthropocene: A Very Short Introduction written by Erle C. Ellis and published by Oxford University Press. This book was released on 2018-02-22 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species - these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news. Even with such robust evidence, the proposal to formally recognize our current time as the Anthropocene remains controversial both inside and outside the scholarly world, kindling intense debates. The reason is clear. The Anthropocene represents far more than just another interval of geologic time. Instead, the Anthropocene has emerged as a powerful new narrative, a concept through which age-old questions about the meaning of nature and even the nature of humanity are being revisited and radically revised. This Very Short Introduction explains the science behind the Anthropocene and the many proposals about when to mark its beginning: the nuclear tests of the 1950s? The beginnings of agriculture? The origins of humans as a species? Erle Ellis considers the many ways that the Anthropocene's "evolving paradigm" is reshaping the sciences, stimulating the humanities, and foregrounding the politics of life on a planet transformed by humans. The Anthropocene remains a work in progress. Is this the story of an unprecedented planetary disaster? Or of newfound wisdom and redemption? Ellis offers an insightful discussion of our role in shaping the planet, and how this will influence our future on many fronts.

Download or read book Enzymes: A Very Short Introduction written by Paul Engel and published by Oxford University Press. This book was released on 2020-11-26 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzymes are the astonishing, tiny molecular machines that make life possible. Each one of these small proteins speeds up a single chemical reaction inside a living organism many millionfold. Working together, teams of enzymes carry out all the processes that collectively we recognise as life, from making DNA to digesting food. This Very Short Introduction explains the why and the how of speeding up these reactions - catalysis - before going on to reveal how we have evolved these catalysts of such extraordinary power and exquisite selectivity. Paul Engel shows how X-ray crystallography has revealed the complex molecular shapes that allow enzymes to function at an extraordinarily sophisticated level. He also examines medical aspects of enzymes, both in the way faulty enzymes cause disease and in the way enzymes can be used for diagnosis and therapy. Finally, he looks at the many varied ways in which individual enzymes, taken out of their biological context, are used nowadays as tools - in washing powders, food production, waste treatment, and chemical synthesis.
