Whether they are testing a new drug, creating new materials, or checking the safety of our food and water, all scientists follow the scientific method. One of the major steps in the scientific method is testing your hypothesis. That's when scientists hit the lab! This volume stresses the important of safety in the laboratory, whether it's a school science lab or the most high-tech research facility. It also examines the proper rules and procedures everyone must follow when working with chemicals in the lab. Fact boxes and full-color photographs support the age-appropriate text.
The scientific method is the process scientists use to test ideas and gather useful results. As part of the scientific method, scientists gather data, form a hypothesis, and test their hypothesis by performing experiments. Not all hypotheses will be right, but that's part of science! Readers will learn the parts of the scientific method, best practices for running experiments, and how to interpret the results of their experiment. Diagrams and fact boxes provide readers with essential information about using the scientific method in the lab.
Performing experiments in a science lab is a fun and exciting way to learn new things, but accidents in the lab are certainly not fun! This book explains the importance of following safety procedures in the lab. Young scientists will learn about the link between good safety and good science. Proper lab procedures can be the difference between a great new discovery and a plain old mess. Colorful photographs, notes on historical experiments, and informational sidebars help readers get a glimpse into the exciting world of laboratory science.
Doing experiments in a laboratory requires equipment. After all, you can't test all the properties of salt and sugar without beakers, a Bunsen burner, and a crucible. With this book, readers will learn about the pieces of equipment found in most science labs, what they're used for, and how to use them. Full-color photographs, helpful diagrams, and informative fact boxes aid readers in understanding the importance of lab safety and proper lab equipment care.
In the newly revised second edition of ABC of Prehospital Emergency Medicine, a team of experienced prehospital practitioners deliver a comprehensive up-to-date guide to the rapidly evolving field of prehospital emergency medicine. The book includes evidence-based practice and expert opinion to meet the needs of the PHEM training curriculum covering operational, clinical and system considerations. An international team of expert editors and contributors have also provided readers with: A thorough introduction to prehospital emergency medicine, including activation and deployment, personal protective equipment, and scene safety and assessment Comprehensive exploration of the primary survey, airway, breathing, and circulation assessments Practical discussions of prehospital anesthesia, analgesia, sedation, monitoring and ultrasound The prehospital management of medical, trauma and psychiatric emergencies How to care for special groups, including the elderly, obstetric, pediatric, and bariatric patients Considerations in mass casualty and chemical, biological, radiation, and nuclear incidents. ABC of Prehospital Emergency Medicine is essential reading for paramedics, doctors, nurses and other prehospital practitioners. The text is ideal for those undertaking subspecialty PHEM training, those studying for postgraduate prehospital degree modules, or practitioners undertaking PHEM exams.
The book in your hands develops the best traditions of the Russian scientific popular literature. Written in a clear and captivating manner by working theoretical physicists, who are, at the same time, dedicated popularizers of scientific knowledge, it brings to the reader the latest achievements in quantum solid-state physics, but along the way it also shows how the laws of physics reveal themselves even in seemingly trivial episodes concerning the natural phenomena around us. And most importantly, it shows that we live in the world, where scientists are capable of ?proving harmony with algebra?. ? A A Abrikosov, 2003 Nobel Prize Winner in Physics
"Ocean of Sound" begins in 1889 at the Paris Exposition when Debussy first heard Javanese music performed. A culture absorbed in perfume, light and ambient sound developed in response to the intangibility of 20th century communications. David Toop traces the evolution of this culture, through Erik Satie to the Velvet Undergound; Miles Davis to Jimi Hendrix. David Toop, who lives in London, is a writer, musician and recording artist. His other books are "Rap Attack 3 "and "Exotica,"
In the history of electronic communication, the last quarter of the nineteenth century holds a special place, for it was during this period that the telephone, phonograph, electric light, wireless, and cinema were all invented. In When old Technologies Were New, Carolyn Marvin explores how two of these new inventions--the telephone and the electric light--were publicly envisioned at the end of the nineteenth century, as seen in specialized engineering journals and popular media. Marvin pays particular attention to the telephone, describing how it disrupted established social relations, unsettling customary ways of dividing the private person and family from the more public setting of the community. On the lighter side, she describes how people spoke louder when calling long distance, and how they worried about catching contagious diseases over the phone. A particularly powerful chapter deals with telephonic precursors of radio broadcasting--the "Telephone Herald" in New York and the "Telefon Hirmondo" of Hungary--and the conflict between the technological development of broadcasting and the attempt to impose a homogenous, ethnocentric variant of Anglo-Saxon culture on the public. While focusing on the way professionals in the electronics field tried to control the new media, Marvin also illuminates the broader social impact, presenting a wide-ranging, informative, and entertaining account of the early years of electronic media.
