A user's manual for our everyday world! "Whether a curious layperson, a trained physicist, or a beginning physics student, most everyone will find this book an interesting and enlightening read and will go away comforted in that the world is not so strange and inexplicable after all." —From the Foreword by Carl Wieman, Nobel Laureate in Physics 2001, and CASE/Carnegie US University Professor of the Year 2004 If you didn't know better, you might think the world was filled with magic—from the household appliances that make our lives easier to the CDs and DVDs that fill our world with sounds and images. Even a simple light bulb can seem mysterious when you stop to think about it. Now in How Everything Works, Louis Bloomfield explains the physics behind the ordinary objects and natural phenomena all around us, and unravels the mysteries of how things work. Inside, you'll find easy-to-understand answers to scores of fascinating questions, including: How do microwave ovens cook food, and why does metal sometimes cause sparks in a microwave? How does an iPod use numbers to represent music? How do CDs and DVDs use light to convey information, and why are they so colorful? How can a CT or MRI image show a cross-sectional view of a person without actually entering the body? Why do golf balls have dimples? How does a pitcher make a curveball curve and knuckleball jitter about in an erratic manner? Why is the sun red at sunrise and sunset? How does a fluorescent lamp produce visible light? You don't need a science or engineering background to understand How Everything Works, all you need is an active curiosity about the extraordinary world all around you.

This study addresses the problem of Internet information services having to meet the increasing information demands of users in the dynamic Internet environment. The purpose of this research was to use K-12 digital reference services as a starting point to better understand the process of building and maintaining Internet information services. The study has three specific objectives: (1) to build and apply a conceptual framework based on complexity research, literature, and the researcher's experience; (2) to use this conceptual framework to empirically describe how organizations, specifically K-12 digital reference services, build and maintain services in the dynamic Internet environment; and (3) to seek commonalties across these descriptions. Qualitative methods (elite interviews and document analysis) were used to elicit descriptions of six exemplary K-12 digital reference services. These descriptions were then compared across organizations to find commonalties. Appended are the Pre-Test Interview Transcript, quality criteria developed by the expert panel, the AskERIC Pre-Test, Internet sites for further information, and a synopsis of data gathering. Eighty-nine tables and figures are included throughout the text. Contains an index. (Author/AEF)

HOW THINGS WORK is about ordinary objects and the physics concepts that make them possible. Its cover illustrates how often waves appears in our world. While ocean surf is clearly an example of waves (p. 250), so is the light form the lighthouse, the rippling motion of the guitar strings, and the sound emerging from the CD in its player. When you pluck a guitar song, you fill it with waves. The strength of these waves and the timbre of the resulting sound depend upon where and how you plucked the string and on the structure of the guitar itself. You can distinguish a guitar from a piano or help by listening for the unique mixture of waves on its strings (p. 242). A lighthouse uses an enormous lens to bend light waves from its lamp into a narrow beam that sailors can see for a hundred kilometers. A large-diameter lens is needed because waves leaving a small-diameter lens spread outward like ripples on a pond and can't stay together as a bright, narrow beam (p. 427). A CD encodes the air pressure fluctuations in sound waves as a pattern of tiny pits on its shiny surface. The CD player reads these pits with a laser to reproduce the recorded sound. Arcs of audio and error-recovery information are arranged in a spinal around the disk's center so that a scratch outward from the middle of the disk is unlikely to cause any noticeable loss of music (p. 424).

Fun and fascinating science is everywhere, and it’s a cinch to learn—just ask a science teacher! We’ve all grown so used to living in a world filled with wonders that we sometimes forget to wonder about them: What creates the wind? Do fish sleep? Why do we blink? These are common phenomena, but it’s a rare person who really knows the answers—do you? All too often, the explanations remain shrouded in mystery—or behind a haze of technical language. For those of us who should have raised our hands in science class but didn’t, Larry Scheckel comes to the rescue. An award-winning science teacher and longtime columnist for his local newspaper, Scheckel is a master explainer with a trove of knowledge. Just ask the students and devoted readers who have spent years trying to stump him! In Ask a Science Teacher, Scheckel collects 250 of his favorite Q&As. Like the best teachers, he writes so that kids can understand, but he doesn’t water things down— he’ll satisfy even the most inquisitive minds. Topics include: •The Human Body •Earth Science •Astronomy •Chemistry Physics •Technology •Zoology •Music and conundrums that don’t fit into any category With refreshingly uncomplicated explanations, Ask a Science Teacher is sure to resolve the everyday mysteries you’ve always wondered about. You’ll learn how planes really fly, why the Earth is round, how microwaves heat food, and much more—before you know it, all your friends will be asking you!
