Review: Awesome book Review: Unfortunately, the authors went as far as stating that speed and velocity are the same thing. They are not and the difference is critical. Then, they try to explain relative velocity without bothering much to explain the meaning of velocity overlooking the need to discuss direction. Some other choices are also questionable. They introduce SI units and then use miles rather than kilometres in their examples. The unit 'metre' is also repeatedly spelled incorrectly. One third through and I feel obliged to stay close to my son to monitor the text and make sure that he does not assimilate wrong ideas. It is disappointing.

Great book that explains the complicated science of Einstein's theory of special relativity in a way that everyone, including children, can get a basic understanding. It is worth noting that this book focuses in "special relativity" and not "general relativity". Would be good to know if there is a book in this series that focuses on general relativity...?
