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. Strange things happen in a relative universe:
length and time are not fixed and depend upon your frame of
reference. If you move at high speed, time slows down, space
contracts and weight increases. So a period of time for someone on
Earth that lasts for hundreds of years may only be a couple of
hours for someone travelling in a rocket close to the speed of
light. 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.
