Happy Physics in One Book

This book is the most outstanding of the author's many popular science works. Its main purpose is not to introduce new knowledge to readers, but to allow readers to "thoroughly understand what they already know", that is, to stimulate readers' sense of novelty about known physical knowledge and to flexibly apply this knowledge to real life. To this end, the author goes against the boring nature of traditional physics books, and instead uses incredible phenomena, interesting exercises, fascinating stories and original questions to arouse readers' interest. The author believes that once readers become interested in a subject, they will pay more attention and consciously explore and learn in depth; the knowledge learned under the guidance of interest will be more "solid".
