Each book in this series follows a packet of energy along a journey.
Each stage of the journey is described in a short chapter, and we learn
what alternative paths the energy might have taken along the way. This
book shows how the energy in wind is turned into a music download. It
explains the science behind sound, how it can be measured, recorded and
stored, what happens in a recording studio, and how our ears hear sound.
The topics covered are illustrated with experiments, amazing facts and
scientific discoveries.
