"Quick and easy step-by-step experiments"--Cover.

Light and sound both travel in waves, but sound waves travel significantly slower than light. Theories like this are difficult to grasp in words, but there are easy ways to see them in action. With this book's simple experiments, young scientists will test out how light can bend and how even invisible sounds can make things move, helping them understand how even the most complex theories work. Through step-by-step instructions, young readers will learn the right way to set up their experiments and expand on concepts they already know.

A groundbreaking study of the trailblazing music of Chicago’s AACM, a leader in the world of jazz and experimental music. Founded on Chicago’s South Side in 1965 and still thriving today, the Association for the Advancement of Creative Musicians (AACM) is the most influential collective organization in jazz and experimental music. In Sound Experiments, Paul Steinbeck offers an in-depth historical and musical investigation of the collective, analyzing individual performances and formal innovations in captivating detail. He pays particular attention to compositions by Muhal Richard Abrams and Roscoe Mitchell, the Association’s leading figures, as well as Anthony Braxton, George Lewis (and his famous computer-music experiment, Voyager), Wadada Leo Smith, and Henry Threadgill, along with younger AACM members such as Mike Reed, Tomeka Reid, and Nicole Mitchell. Sound Experiments represents a sonic history, spanning six decades, that affords insight not only into the individuals who created this music but also into an astonishing collective aesthetic. This aesthetic was uniquely grounded in nurturing communal ties across generations, as well as a commitment to experimentalism. The AACM’s compositions broke down the barriers between jazz and experimental music and made essential contributions to African American expression more broadly. Steinbeck shows how the creators of these extraordinary pieces pioneered novel approaches to instrumentation, notation, conducting, musical form, and technology, creating new soundscapes in contemporary music.

Uses activities and experiments to introduce the properties of light and sound.

This big book introduces children to the basics of science in a fun, appealing way. Each experiment is accompanied by an introduction to a scientific concept, clear photographic step-by-step instructions, a list of materials needed, and a Q&A explanation. At the end, children can test what they've learnt with Quiztime. Also includes a glossary.

KINGFISHER YOUNG KNOWLEDGE LIGHT AND SOUND introduces readers to the sources of light and explains how we hear sounds.

What is light? Where are optics and photonics present in our lives and in nature? What lies behind different optical phenomena? What is an optical instrument? How does the eye resemble an optical instrument? How can we explain human vision? This book, written by a group of young scientists, answers these questions and many more.
