The "Eyewitness Science" series follows the story of science, tracing the major discoveries through the eyes of the great scientists. The text is simple and straightforward, and each spread contains detailed artwork and photographs. The series combines landmark experiments in the history of science with the human element - the great men and women of science. Special features include: demonstrations which re-create experiments and expand important principles; artworks which explain how and why things work; specially built 3-D models which aim to make clear even the most complex concepts; and words and pictures which work together to explain scientific principles clearly and concisely. "Electronics" covers such topics as: the pre-electric world; early amplifiers; time and frequency; signals, codes and information; microprocessors; and transducers.

Spin Wil's black medallion - and you'll find the medallion's silver arrow and triangle turn into a five-pointed star. With each new adventure, another tiny gold symbol glimmers on the magical medallion. What do the symbols mean? All cousins Wil and Sophie know is that an ancient and nasty secret society - none other than the Serpent's Chain - wants its black medallion back. A prize trip to Iceland, land of history, danger, and galdur - magic - sends Wil and Sophie on another quest to unravel the mystery of the Serpent's Chain. Meanwhile, someone is tampering with fortune-telling crystal balls and their friend Mr. Bertram has been imprisoned, falsely accused of murder and the theft of a precious manuscript. When the cousins are captured by trolls, it looks like they and their adventures might end up in the soup!
