The first book of Korea's Cosmos! Until now, the history of the universe has been described from the Western perspective. As a result, too many people still believe that Eastern traditions are unscientific and wrong while Western ones are scientific and right. This prejudice produces blind Western-centrism and adversely affects on every field of science. However, Korea has been developing a system of Astronomy since 6000 years ago; and in this book, Professor Seok Jae Park who is a trained astronomer and a President of Korea Astronomy and Space Science Institute, discusses how ancient Korean Cosmology still dominates life of ordinary Koreans even today. If you wish to understand the mind of a Korean person, this is a must read book. If you wish to understand the development of science in the East, this is a must read book. All important technologies that dominate modern day such as printing press came from ancient Korea and with the understanding of traditional Korean Astronomy the humanity will be able to understand the universe and reality of our every day lives better.
