Can you believe any people who drew the bronze mirror 2,400 years ago with a hand-cutting of the delicate and detailed lines that are so difficult to reproduce with the technology we have today? That's not a millimeter of distance. Can you believe it if you drew a line at 2 millimeter apart? The number of dolmens that have been found in the world is about 80,000. But if you have a country of over half a million years, how great is this people with a giant culture? Not only these numbers, but

The history of the High Line, which is not yet known much in the 5,000 years of South Korea's history. We can only guess where the land of the Kojo ship was, but we don't know exactly where it was and how powerful the ancient nation was, and how we felt about its existence as an ancient nation through Chinese history history books, Xhosa and other literature. So in the history books and history books of South Korea, we've always read about the Kozo-sun, and we're going to see the first two

The secret of our technology. It's inspiring to know that there are many people who are not historians, but who are interested in history. Because if we're interested in our history in a variety of fields, we'll understand our own history more deeply and we'd be able to solve our own. If the technologist, like the author, is interested in our technology history, then our research and stories will be much more profound and more extensive. Our ethnic scientific genes were also written from

Now, in '20, we are following the lifestyle of Western culture. The eye is open on bed, and everything about everything in life is Western style. This is a strange thing to think about when we think of all four ancient civilizations that happened in the Orient. In ancient times, it was the Orient, which had a better civilization than the West, and how in just a few centuries, almost everything in the world changed Western ways. This is in the short time period of centuries, when technology has

In elementary school, middle school and high school, I had a course called State which was not necessary today. At that time, I and other friends thought the same. The course of the State is a memory. So I remember when I was studying, I just remembered it all. The state, and the world history, was not just learning about the big events of the day. I remember learning about the architecture, the art and the weapons of the day. But few people know why war, horse, drought, hurricanes, and other

The author of this book is from engineering, a favorite of history. As a professional historian, it did not resolve the demands of the government from a historical point of view, nor does it translate from a personal perspective of the historian. I've been trying to deliver to my readers the objective scientific excellence of our country's history, as it were, in the face of the facts of scientific evidence based on historical data. And also, we've made our sciences better than the West. The

It was certainly a time to see how much of our technology has gone well since the high-frequency era. It seems obvious that it is so exclusive that it has a remarkable metal processing, manufacturing and construction technology, not a country behind the surrounding countries. The old masochist is a cavalryman ahead of the Roman irons, and he uses armor gloves to excel in efficiency and mobility. Europe was able to apply itself to the crusaders in the 16th century, and already with weapons and

[The more you know, the secret of our great science technology.]. The word that is most appealing in this statement is ‘ greatness ’ in the phrase ‘ the greater the knowledge. ’. This greatness opens the book with the hawk's eye, as it will naturally be known. I'm proud to see my country's smart phone competing with Apple's products in the world market. But on the other hand, it is also a strange feeling that among the Nobel Prize winners, the world's official agency, our country's scientists

The legacy of the ancestors' brilliant heritages gives us a sense of our national excellence. The Secret of Our Sciences was thought to be a book that could be studied and learned more specifically about our people's scientific excellence and creativity. Every time you turn the page, you become proud and proud. Part 5 is the Iron Guard, the ancient metal crafts, the largest woodwork construction in the ancient world, the stonestones of the culture, and the world's first two rocket launchs
