Inmore detail, Part 1 discusses the scientific discoveries andbreakthroughs, doubts and truths, as well as its overallconfigurations, while Part 2 explores the issues of pattern,inheritance, influence, and value. In short, the authorintends to sum up and share some research findings inorder to receive further valuable suggestions and advice.
