Before we can understand Einstein’s special theory of relativity we need to fully understand what time and space is. My First Book of Relativity achieves this as it starts by explaining exactly what time is and how it is measured, from sundials to the exceptionally accurate atomic clock. Sheddad Kaid-Salah Ferrón then goes on to define in a beautiful concise way what space is and how it is measured, explaining how using standard units of measurement, such as the metre stick, came into being.
The next important concept to understand is speed. Again, Sheddad Kaid-Salah Ferrón, walks the reader through the concept of speed in a clear and easy to understand fashion, so that when he goes on to explain how movement is relative it just all makes sense and the reader can make the connection instantly to how frames of reference are used to measure positions, distances and speed, just as Galileo Galilei had said 400 years ago. Her then goes on to explain exactly why light always travel at the same speed of 299,792 kilometres per second. The illustrations support and extend the readers understanding with each double-page spread having its own distinctive limited palette.
Each of Einstein’s thought experiments are broken down into small segments by organising the text into short, distinctive sections using the engaging illustrations, bullet points, bold and capitalised words to emphasise important information. My First Book of Relativity talks us through the incredibly difficult to understand concepts of time dilation, length contraction and mass increasing outlined by Einstein in his special theory of relativity in a fun, appealing and easy-to-read way so it is accessible to young readers of about 8+.
This is an ideal book for introducing the concepts of speed, light and movement to the class, or your own child. I believe it will inspire young scientists to think about time and space and even come up with their own thought experiments.
