KBS Special [Science and Civilization of Korea] Great Heritage [Part 1] - Mathematics Chosun ▶ I don't know math Everyone must have felt anger and frustration about math at least once during their school days. It's time to change the memories that made us 'math dropouts' into surprise and joy. The first question at the beginning is 'Was there math in the Joseon Dynasty?' ▶ Magic square and the beginning of modern combinatorial mathematics, - Choi Seok-jeong's [Gusoo-ryak] Encyclopedia of modern combinatorial mathematics, [Combinatorial Theory Handbook]. In this book, there is a person whose name is proudly listed above that of the world-renowned mathematician Euler. It is Choi Seok-jeong, who served as Prime Minister of the Joseon Dynasty eight times. How was that possible? We will examine the concept of the '9th magic square' in his book [Gusoo-ryak] through the 'Joseon Baseball Team' consisting of the King's Team, Farmers' Team, Women's Team, and Police Team. In addition, we will examine the meaning of the magic square and how it is connected to modern mathematics and engineering, thereby shedding light on the influence Choi Seok-jeong had on modern society. ▶ Tenth-order equations and a math competition, - Hong Jeong-ha of [Guiljip] In the summer of 1713, a math competition between Joseon mathematician Hong Jeong-ha and Qing mathematician Ha Guk-ju took place. Hong Jeong-ha, who easily solved the problems Ha Guk-ju gave him, made a big move. However, Ha Guk-ju was unable to answer them! What was this problem that silenced the Qing mathematician, and how did Hong Jeong-ha solve it? The secret was the calculation tool, 'Sangaji'. Joseon mathematicians used 'Sangaji' to solve complex equations up to tenth-order equations, from land surveying to tax calculations and military camp construction, and applied them in real life... Joseon mathematics was also used in one of Admiral Yi Sun-sin's famous tactics, the crane-wing formation! Let's learn about the secrets with Joseon mathematician Hong Jeong-ha and his book [Guiljip]. ▶ Math is fun 'Math Joseon' presents how mathematicians of the past viewed and handled numbers in a fun way, using real-life footage, reenactments, computer graphics, and 3D animation. Mathematicians and engineers' verification and advice add fun to the facts, and actor Lee Soon-jae appears as a presenter to add friendliness. You will be able to feel fun in the midst of difficulty by looking at difficult mathematics that made us angry and gave up through the unique framework of 'achievements of Joseon mathematicians.' #Mathematics #GuSuRak #GuIlJip
