The particle accelerator is the most widely used large scientific instrument in the world. It is becoming the key strategic element for any country's scientific development programme. These devices, which help us understand the world around us, can also be used to analyse, cut, produce, engrave, manufacture, heal and probably more. They operate on different scales spanning 14 orders of magnitude! While accelerators are used by scientists around the world for a variety of practical applications, the analysis of the physical laws that govern them, and how they are intertwined, leads to an abstraction and a metaphysical reflection on the place of man in the universe - from the infinitely small to the infinitely large. The book's beautiful abstract illustrations propel the reader into these other dimensions.
