About

KAIST 수학과를 최우등 졸업, 프린스턴대에서 조합론, 그래프이론으로 박사를 했습니다. 제가 수학을 하면서 느꼈던 재미를 많은 분들에게 공유하고 싶습니다. 수학이 재미있었던 적이 있으신가요? 수학에는 게임처럼 재미를 느낄 수 있는 요소들이 많지만, 그런 요소들을 접하긴 쉽지 않은 것 같습니다. 수학을 잘하려면 수학의 재미를 느끼는 것보다 좋은 방법이 없습니다. 재미가 있으면 시키지 않아도 스스로 찾아서 하게 되고, 수학의 맛을 알수록 세상을 보는 관점, 세상을 해석하는 시야가 달라집니다. 24.03.12 34님들 200k 23.05.12 34님들 150k 23.02.16 34님들 100k 22.11.20 구독자 50k 22.10.30 구독자 20k 22.10.14 구독자 10k 22.10.06 구독자 5k 22.08.30 구독자 2k 22.08.15 구독자 1k 22.07.01 시작
