In popular culture, more and more science fiction films are inspired by sciences such as Star Wars and Interstellar Series (2014). Also bioscientists like Hawking in Theory of Everything (2014). Then Einstein's film in the television series Genius (2017) and finally Biopic on Neil Armstrong in First Man (2018). These films show a growing interest in science, especially astronomy and cosmology.

However, the attraction of scientists often stops watching theaters. The community seems too busy to penetrate the universe. They are reluctant to read dense scientific books or to attend scientific seminars. For this reason, Neil deGrasse Tyson, American astrophysicist, wrote this book Astrophysics for Busy People (2018). Tyson's book also gave the order of sentences: "For all those who are too busy, so they do not have time to read thick books, but they are still looking for channels into space."

This book provides basic knowledge of all the great ideas and discoveries that support the modern understanding of the universe. The author invites readers to explore the universe, 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 they are everywhere. Newton's discovery of the law of gravity of an apple falls from the tree, it also turns out to be true for planets, asteroids and comets around the Sun (page 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 in a language full of empathy and amazement, but it was still fun because of the great humor.

For example, when we talk about the discovery of invisible light, gamma rays. He wrote: "Anyone watching too much science fiction knows that gamma rays are bad for people, people can be greedy and muscular, or remove warts from the wrists" (p. 107).

This book also discusses the possibility of another life outside Earth. Exoplanets or planets that are supposed to be similar to Earth were first discovered in 1995. The amount now discovered is three thousand. The universe is huge.

It is estimated that there are up to 40 billion Earth-like planets in the Milky Way galaxy itself. That is, Tyson said, planets that people sometimes want to visit (page 131). Everything that sounds exotic and hard to believe. However, was not it also considered crazy when he proposed Copernicus, the Earth around the Sun?

Still many unknown. People have just begun to celebrate the universe. This book helps readers to realize so many interesting things about astronomy and cosmology. This book is suitable for those who are too busy to understand the universe in the classroom, textbooks or documentaries. The Busy People Astrophysics Book can be a fun and fun short introduction.
