"When people think of mathematics, they invariably consider it difficult. Through this book, I wanted to show how closely mathematics relates to everyday life and how enjoyable it can be."

Kim In-su, Professor in the Department of Mathematics, has made significant contributions to the development of mathematics education through 35 years of research and writing in mathematics. Even more notable is his effort to make mathematics—often perceived as difficult—accessible and enjoyable to the general public.

The book written last year, The World of Mathematics (Books Hill), compiles his "Interesting Stories of Mathematics"—a series he serialized in a daily newspaper for more than ten years since 2000—along with various stories and episodes embedded in mathematics, woven entertainingly. This book was selected this year as an Outstanding Academic Book by the National Academy of Sciences.

Composed of six chapters, the book presents various concepts in an accessible way for general readers. It contains hidden truths and intriguing mathematical facts intended to pique readers' curiosity and foster interest in mathematics.

Beginning with the story of "interesting numbers," it covers the meaning of zero, the relationship between infinity and mathematics, the concept of prime numbers used like codes, accounts of great mathematicians, and a variety of engaging stories about applications and developments in mathematics.

Professor Kim In-su said, "I am very pleased that the work resulting from my efforts as a mathematician to make mathematics more enjoyable and understandable to the general public has been selected as an Outstanding Academic Book." He added, "I hope that many people will discover a new enjoyment of mathematics through this book."
