In folk culture, more and more science fiction films are inspired by science such as the Star Wars and Interstellar series (2014). Also, bios scientists like Hawking in Theory of Everything (2014). Then, Einstein's film on the Genius TV series (2017), and finally the biopsy for Neil A Armstrong in the first man (2018). These films show the growing interest in science, especially astronomy and cosmology.

However, the attraction of scientists often stops watching in theaters. The community appears to be too busy to penetrate the universe. They are reluctant to read thick scientific books or attend scientific seminars. For this reason, Neil deGrasse Tyson, an American astrophysicist, wrote this book of astrophysics for busy people (2018). Tyson also devoted the book to a series of phrases, "For all those who are too busy so they do not have time to read thick books, but they still seek channels in the universe."

This book provides a basic understanding of all the great ideas and discoveries that support the modern understanding of the universe. The author invites readers to quickly explore the world, from the history of the Big Bang to the search for life in the universe.

It reveals the power and beauty of the laws of physics because it is everywhere. Newton's discovery of the law of the gravity of an apple falling from a tree is shown to apply to planets, asteroids and comets around the sun (p.13).

The book expresses the relationship between gravity and mountain height. The reason for objects in the universe is round. The origin of the element name in the periodic table, until scientists find "invisible" light such as infrared and ultraviolet. Tyson wrote it with a tongue full of empathy and surprise, but he was still entertaining because of the great humor.

For example, when talking about the discovery of invisible light, gamma rays. He wrote: "Whoever is watching a great deal of scientific imagination knows, gamma rays are bad for man, people can be green and muscular, or remove spider webs from their wrists" (page 107).

This book also looks at the possibility of life beyond the Earth. The exoplanets or planets that appeared to be similar to Earth were first discovered in 1995. Now the amount that has been found is over three thousand. The universe is enormous.

It is estimated that, in the Milky Way Galaxy alone, there are up to 40 billion planets resembling Earth. That is, said Tyson, the planets people would like to visit someday (page 131). All this is exotic and hard to believe. However, he was also not considered as mad when Copernicus proposed the Earth around the Sun?

There are still many unknowns. People have just begun to celebrate the universe. This book helps readers to realize as much interest in astronomy and cosmology. This book is suitable for those who are too busy to understand the universe in the classroom, textbooks or documentaries. An astrophysics book for busy people can be a fun and entertaining short introduction.
