It's never too early to start exploring big ideas. This companion volume to 'My First Book of Quantum Physics' introduces complex science to children through bright illustrations and amusing text. Einstein's theory of relativity is one of the cornerstones of modern physics but it requires a total rethink of our notions of time and space.
It's mind-boggling stuff, but the theory of relativity has a real impact on our world today. A car's GPS navigation system, for example, uses information received from orbiting satellites and is designed to account for the fact that time ticks at a different rate on these satellites than it does on the ground. Without allowing for relativity's effects, after just a day, your whereabouts according to GPS could be up to 5 miles (8km) from your actual location.
So to find out more about how our universe works and how space and time are connected, look no further than this fascinating, illustrated guide to relativity.
