[강연] 무엇이 무엇이 똑같을까? 수학으로 바라본 대칭 정복기 1_by 이승재 / 2024 봄 카오스강연 '세상에 나쁜 수학은 없다' 1강 첫 번째 이야기

🔸2024 Spring Chaos Lecture 'There's No Bad Math in the World' Lecture 1🔸 🔹Lecture | What's the Same? Conquering Symmetry Through Mathematics 🔹Speaker | Professor Seungjae Lee (Department of Mathematics, Incheon National University) Symmetry: We often encounter it in nature and in our daily lives. From our reflections in the mirror, symmetrical buildings and works of art, to hexagonal snowflakes and beautiful flower petals. Symmetry brings us beauty and comfort. However, symmetry is hidden in many places beyond the visible visual elements, supporting our lives. This lecture will explore how symmetry has solved problems pursued by humanity since ancient civilizations, since the dawn of counting, and what symmetry means from a mathematical perspective. We will also examine Lee Im-hak, a world-renowned Korean mathematician who pioneered Korean mathematics. 📌Table of Contents 00:00 Start 08:49 What is Algebra? 10:09 Lecture 1, First Story 11:16 A Story of Two Mathematicians: Niels Henrik Abel & Évariste Galois 17:04 Abel and Galois, Who Proved That Equations of Degree 5 or Higher Cannot Be Rooted 20:17 A Story of Professor Imhak Lee, a Korean Mathematician ♥Chaos Foundation: Sharing the Joy of Science ~ Home: ikaos.org (Learn about lecture events upon registration) Facebook: facebook.com/kaosfoundation YouTube:    / kaosscience   Instagram: instagram.com/kaosfoundation #Algebra #GroupTheory #Imhak Lee #Mathematician #KoreanMathematician #Galois #ÉvaristeGalois #Abel #NielsHenrikAbel #FiniteEquation #FiniteGroup #FiniteGroupClassification #SeungjaeLee #HyungjooPark #YeoneungKim #YeriShin #ThereIsNoBadMathematicsInTheWorld #SenaSu #ChaosLecture #ChaosFoundation #ChaosScience #Lecture #MathLecture #MathLecture #Mathematics
