From the outset this book tries to portray the often complex world of Physics in a easy to understand way. Many books have attempted this but have failed, this is truly one of the best Physics books I have read for my age group. This book was one of the major contributing factor in me passing PHO2. This is one of the greatest rewriting of a book I have ever read. And pays much due respect to Gamov for his inventive way of teaching physics, to both physicists and the average person alike. And that is why I have given it 4 stars.
