This book is purely philosophical. Mathematics is not required. The author has tried to explain Space,Time and Relativity in a very understandable way.
Beginners who want to read about Special Relativity, I ll recommend this book for them. And not just relativity, many other concepts and brilliant arguments of some philosophers are there. But those who love to read adventurous and interesting books, may find this boring and dry. Interest and patience is required.😊
