A Complete Collection of Unpopular Knowledge

The writing style of this book is very interesting and the content is very rich. It contains some interesting and unpopular knowledge that is not usually noticed. The author's writing style is concise and clear, making it easy to understand. I especially like the parts about astronomy and geography. For example, the question I just mentioned about whether it is possible to go back to the time when the universe was formed is really interesting. This book is like a treasure trove of knowledge, and you can gain something new every time you open it.

Rich, colorful content and engaging plot

In fact, I rarely comment! Reading books is just to pass the time. Some books can increase wisdom! Some books are for gold coins

The content is engaging and highly recommended.

The plot has ups and downs and the description is true and objective.
