안녕하세요!
혹시 "엉덩이는 한 개일까, 두 개일까?"라는 질문을 들어본 적 있나요?
논란은 일었지만 아직 확실한 답을 찾지 못한 일명 '엉덩이 개수 논란'인데요,
이번 4월호 수학동아에서는 그 답을 수학자분들께 한번 물어봤답니다!
특히 황선욱 숭실대학교 수학과 명예교수는
엉덩이를 위상수학적으로 보면 한 개라고 밝히기도 했습니다.
하지만 나머지 수학자들은 알 수 없음, 또는 한 개이자 두 개로 볼 수 있다고 했는데요,
그럼 여기서 질문!
위상수학적으로 사람의 몸은 몇 개의 구멍을 가진 도넛과 같을까요?
수학동아 4월호 '엉덩이 개수 논란' 기사에서 위상수학에 대한 설명을 읽고,
나름의 답을 이유와 함께 제시하는 분께 선물을 드립니다!
아래 비밀댓글에 의견과 함께 이름, 연락처, 주소를

과연 정답자는 누구일지~?

오 저는 엉덩이는 하나라고 생각해요 모두 엉덩이를 엉덩이'들'이라고 부르진 않잖아요?
