In popular culture, more and more science-fantasy movies have inspired science such as Star Wars and Interstellar Series (2014). Also biographical scientists like Hawking in Theory of All (2014). Then, Einstein's movie in the Genius television series (2017), and finally biopic about Neil A Armstrong in the first man (2018). These films show an increasing interest in science, especially astronomy and cosmology.

However, the attraction of scientists often stops watching in theaters. The community seems too busy to pervade the universe. Nerado read thick science books or attend science seminars. Thus Neil deGrasse Tyson, the American astrophysicist, wrote this book Astrophysics for Busy People (2018). Tyson also devoted a book with a series of sentences: "For those who are too busy and do not have time to read thick books, yet they are still seeking channels for the universe."

This book provides a basic understanding of all the great ideas and discoveries that support the contemporary understanding of the universe. The author invites readers to briefly explore the cosmos, from the history of the Great Burst to the Quest for Life in the Universe.

He reveals the power and beauty of the law of physics because they are everywhere. Newton's discovery of the gravitational apple law that falls from the tree is also apparent to the planets, asteroids, and comets around the sun (p. 13).

The book expresses the link between gravity and mountain height. The reason for objects in the universe is round. The origin of the element names in a periodical table, while scientists do not find "invisible" light such as infrared and ultraviolet. Tyson wrote a language full of compassion and wonder, but still was fun for a lot of humor.

For example, when it comes to discovering invisible light, gamma rays. He wrote: "Everyone who observes too many science fiction knows, gamma beams are bad for people. People can be green and muscular or remove spider webs from the wrist" (p. 107).

This book also discusses the possibilities of other life outside the Earth. Exoplanets or planets suspected of being similar to Earth were first discovered in 1995. Now, the amount found penetrates three thousand. The universe is huge.

It is estimated that only in the Milky Way galaxy there are up to 40 billion planets of similar Earth. That is, Tyson said, the planets one day people want to visit (page 131). Everything sounds exotic and hard to believe. However, did not this be considered crazy when Copernicus suggested the Earth around the Sun?

There are many unknowns. People are just beginning to celebrate the universe. This book assists readers that they are so interested in astronomy and cosmology. This book is suitable for those who are reluctant to understand the universe in the classroom, textbooks, or documentaries. An astrophysical book for busy people can be a fun and entertaining short presentation.
