Light is strange, sometimes dazzling, like very bright sunlight, sometimes dim, like starlight. It can be coloured, it can be white, it can also be invisible. Light has incredible energy, which you can feel on your skin when you are sunbathing. Light zooms at amazing speeds across the Universe. But what is light? We know a great deal about how light behaves, but no one, not even the most eminent scientist in the world, can say exactly what light is! When planet Earth was formed, its light came from the sun, stars and lightning flashes. Millions of years later, humans have found many different ways of making light. The most amazing light source ever invented is the LASER. Lasers are used in almost every part of life on our planet. Some lasers are billions of times more powerful than a light bulb. Lasers might even be able to make mini-suns to solve our energy crisis when oil runs out!

Written by real-life scientists, the books are bublling with the authors' enthusiasm for their subjects - in contrast to the more usual fare written by arts graduates with a sideline in information books for children... Scientists are always being told they speak a jargon the rest of us can't understand - so how have these four succeeded in writing intelligible and fascinating scripts? The key lies in their sense of science as both easy and fun, coupled with experience in addressing children.
