Use of historical and comparative approach to examine and critique the development of paid care work in the twentieth-century including health care, education and child care, and social services.

The university has very different priorities from the salesroom, the museum from the antiques fair, but the challenge of instrument history is to integrate connoisseurship, technical insight and historical sensitivity, while not neglecting the trade institutions and practices of the makers and remaining familiar with instrument populations in both the captivity of museums and the relative freedom of the market-place. This volume is presented to Gerard Turner, who has been at the forefront of promoting instrument studies in recent years. After a twenty-five-year association with the Museum of the History of Science at Oxford, a Visiting Professorship in the History of Scientific Instruments was established for him at the Imperial College, London, in 1988, from where he has been able to increase his research in this field.

Illustrated step-by-step instructions for more than 30 musical instruments which children and adults can make together. Made from easy-to-find materials, each instrument can actually be played.

Rhythm Made Easy takes rhythm and turns it into simple, digestible clapping exercises that can be executed by anyone looking to learn how to count rhythm. Each exercise builds on the last, and Ross the Music Teacher has a video example for each and every exercise, totaling 100! Isolate rhythm and master it, so that you can count flawlessly on your instrument.

A clear, practical, first-of-its-kind guide to communicating and understanding numbers and data—from bestselling business author Chip Heath. How much bigger is a billion than a million? Well, a million seconds is twelve days. A billion seconds is…thirty-two years. Understanding numbers is essential—but humans aren’t built to understand them. Until very recently, most languages had no words for numbers greater than five—anything from six to infinity was known as “lots.” While the numbers in our world have gotten increasingly complex, our brains are stuck in the past. How can we translate millions and billions and milliseconds and nanometers into things we can comprehend and use? Author Chip Heath has excelled at teaching others about making ideas stick and here, in Making Numbers Count, he outlines specific principles that reveal how to translate a number into our brain’s language. This book is filled with examples of extreme number makeovers, vivid before-and-after examples that take a dry number and present it in a way that people click in and say “Wow, now I get it!” You will learn principles such as: -SIMPLE PERSPECTIVE CUES: researchers at Microsoft found that adding one simple comparison sentence doubled how accurately users estimated statistics like population and area of countries. -VIVIDNESS: get perspective on the size of a nucleus by imagining a bee in a cathedral, or a pea in a racetrack, which are easier to envision than “1/100,000th of the size of an atom.” -CONVERT TO A PROCESS: capitalize on our intuitive sense of time (5 gigabytes of music storage turns into “2 months of commutes, without repeating a song”). -EMOTIONAL MEASURING STICKS: frame the number in a way that people already care about (“that medical protocol would save twice as many women as curing breast cancer”). Whether you’re interested in global problems like climate change, running a tech firm or a farm, or just explaining how many Cokes you’d have to drink if you burned calories like a hummingbird, this book will help math-lovers and math-haters alike translate the numbers that animate our world—allowing us to bring more data, more naturally, into decisions in our schools, our workplaces, and our society.
