수학동아 - 폴리매스
[잡담] 굿 커뮤니티 캠페인으로 새로 만들어진 폴리매스 규칙을 공개합니다!
수학동아 2020.06.08 23:30
조회 2425
안녕하세요. 수학동아 조가현 편집장입니다.
폴리매스가 더 좋은 커뮤니티로 발전할 수 있도록 굿 커뮤니티 캠페인 기간 동안 여러 의견을 주셨는데요.
폴리매스가 항상 즐겁고 유익한 장소가 되기를 바라는 마음으로 새로운 규칙 3개를 추가했습니다.
회원 여러분께서는 꼭 폴리매스의 취지를 되새기면서 서로 존중하셨으면 좋겠습니다.
폴리매스의 취지는 수학을 주제로 다양한 나이, 지식을 가진 사람들이 자유롭게 의사소통하며 모두 함께 수학적으로 발전하는 것입니다.
1. 존댓말을 사용합니다.
- 반말 자체가 나쁜 건 아니지만 의도와 다르게 상대방에게 상처를 줄 수 있어 폴리매스에서는 항상 존댓말을 사용합니다.
2. 비속어 사용을 금지하며 비꼬는 말도 하지 않습니다.
- 다른 의견, 오류 지적, 개선 사항 등 어떤 의견을 내도 좋지만 상대방을 존중한다는 느낌을 받을 수 있도록 합니다.
3. 문제에 대해 질이 높고 낮음을 평가하지 않습니다. 오류 지적이나 문제를 더 어렵게 또는 쉽게 바꾸는 것, 일반화하는 것은 모두 추천합니다.
- 좋은 문제, 질 낮은 문제란 무엇인지에 대한 활발한 토론이 이뤄졌는데요. 수학동아가 생각하는 좋은 문제란 문제를 푸는 사람이 재밌게 풀 수 있는 문제입니다.
공식을 알면 바로 풀 수 있는 문제를 질이 낮다고 평가하는 분이 있는데요, 공식을 처음 배운 사람에게는 그 문제도 좋은 문제일 수 있고, 공식을 안다고 해도 다른 방법으로 푸는 방법을 생각해본다면 이 또한 좋은 문제일 수 있습니다.
인수분해가 안 되는 2차 방정식을 근의 공식을 이용하지 않고 푸는 방법을 연구하다 새로운 해법을 제시한 수학자의 연구를 수학동아 2020년 2월호에서 소개했었죠.
http://dl.dongascience.com/magazine/view/M202002N024
또 비유클리드는 ‘유클리드의 공준 5개가 모두 필요한가’라는 기본적인 질문에서 시작된 학문입니다. 문제를 어떻게 해석하고 바라보느냐에 따라 질 낮은 문제도 좋은 문제가 될 수 있습니다.
따라서 2019년 12월 16일 공개한 자유게시판 이용 수칙을 폴리매스 전체 규칙으로 확대하며, 위의 3가지 규칙을 추가합니다.
폴리매스 이용 수칙
1. 바른 언어로 글을 작성합니다.
2. 게시물 내용을 잘 설명하는 알맞은 제목을 답니다.
3. 사실과 다른 내용은 올리지 않습니다.
4. 댓글로 소통할 때는 상대방을 존중합니다.
5. 종교나 이념, 정치를 드러내는 글과 이미지, 사이트 주소는 게시하지 않습니다.
6. 불법 소프트웨어는 올리지 않습니다.
7. 정보의 출처를 꼭 밝힙니다.
추가 8. 존댓말을 사용합니다.
추가 9. 비속어 사용을 금지하며 비꼬는 말도 하지 않습니다.
추가 10. 문제에 대해 질이 높고 낮음을 평가하지 않습니다. 오류 지적이나 문제를 조금 더 어렵게 또는 쉽게 바꾸는 것, 일반화하는 것은 모두 추천합니다.
규칙을 어긴 사례를 발견하면 다음 메일 주소로 신고해주세요! gahyun@donga.com
신고할 때는 본인 아이디와 이름, 연락처, 신고 내용, 신고하는 글의 url을 꼭 적어주세요.
감사합니다.
조가현 드림
꼭 지키겠습니다
새 규칙 잘 지키겠습니다!

알겠습니다. 확실히 1+1도 단순한 방법만으로 풀수 있는 것이 아니죠.
그런데 다음 세 문제 유형에 대하여 어떠한 태도를 취해야 하는지 궁금합니다.
1. 수학과 넓은 범위의 과학에서 크게 벗어난 문제
ex)그레고리력 기원후 776년에 한국사에서 일어난 사건은 무엇인가?
2. 과학과 관련이 있더라도 전문 상식이 없으면 푸는것이 불가능한 문제
ex)호지 추측을 증명하라<<일반인은 이해하는것도 힘듦
3. 푸는 것이 불가능한 문제
ex)제 닉네임은 왜 길고양이일까요?
폴리매스는 수학으로 소통하는 곳이니만큼 수학 문제를 올려주세요. 단 퍼즐이나 암호 등은 수학의 뿌리가 있으므로 올려도 좋습니다. 생활 속 문제도 수학의 언어로 바꿔 올리는 건 가능합니다.
수학 난제 역시 올릴 수 있습니다. 당장 푸는 건 어렵지만 이 문제를 풀기 위해서는 어떤 분야를 공부해야 하는지, 어떤 배경지식이 필요한지 등을 댓글로 서로 공유하면 좋을 것 같습니다. 페르마의 마지막 정리를 해결한 앤드루 와일스는 10세 때부터 이 문제에 대해 관심을 가지고 문제를 풀기 위한 공부 계획을 세워 난제를 해결했습니다.

음... 1번 같은 경우는 폴리매스에 올리면 좀 그렇죠. 이건 인정합니다. 그런데 2번과 3번 케이스같은 경우는 올려도 괜찮을 것 같습니다(제 말은 '어, 이건 그냥 완전히 올려도 돼!'가 아닙니다. 흑백논리로 받아들이진 말아주세요). 2번에서 예시로 올려준 문제는 마구 남용만 안 하면 괜찮을 것 같네요. 확실히 '~를 증명하여라'는 만들기 쉽긴 하죠. 하지만, 자신이 그걸 충분히 많이 고민해보고 낸 거면 저런 거라도 괜찮을 것 같습니다. 저런 건 푸는 사람이 '호지 추측이 무엇인가요?'라고 질문을 하고, 출제자가 그거에 대하여 자세히 설명해주고, 또 거기서 이해가 안 가면 또 질문해주고... 이렇게 가면 바람직하다고 생각합니다. 사실 제가 그래서 질문 같은 건 공댓으로 다는 걸 선호합니다(아 물론 너무 결정적인 질문이면 또 몰라도요). 비댓으로 답은 몰라도 질문을 달면 질문한 사람은 이해할지 몰라도 다른 사람이 그 문제를 풀 때 또 그 짓을 반복하고, 또 다른 사람이 이해가 안 되면 또 이 짓을 하고... 이것보단 공댓 한 번으로 질문을 다는 게 더 좋을 것 같기 때문입니다. 암튼 2번 같은 경우는 이렇게 본인이 이것을 충분히 많이 고민해보고, 이 정리 또는 추측을 다른 사람에게 설명해 줄 수가 있으면 괜찮다고 생각합니다.
3번에서 예시로 올려준 문제는 반대합니다. 그런데 저런 문제는 '풀 수가 없어서'보다는 '수학과 조금도 관련이 없어서'가 더 적합한 것 같습니다. 웃시산님은 개편 후에 활동하신 분이라서 잘 모르실 수도 있으실 텐데, 제가 활동을 시작한 2018년에는 그런 문제가 꽤 있었습니다. jeuno님이 예전에 매우 많이 고민해봤는데 도저히 모르겠어서 올리신 문제가 하나 있었습니다. 그리고 저를 포함한 다른 분들이 그 문제에 대해 의견을 나누고, 풀어 주셨습니다. 그리고 그분은 '오랫동안 해결되지 않은 게 풀려서 호기심이 해결된 느낌이다'면서 기뻐하셨죠. 저 역시 그런 적이 있고요. 물론 이걸 레벨 올리기 위해 남용한다... 네, 그건 인정합니다. 그런데 '충분히 많이 고민을 해 봤다면' 남용을 할 수도 없지 않을까요? 물론 이건 2018년 이야기라 지금에 맞지 않는다는 말을 하실 수도 있습니다. 그러나, 그때든 지금이든, 폴리매스의 취지는 변치 않았습니다. 그리고 저 때의 이야기는 폴리매스의 취지에 어긋나진 않죠. 따라서 지금도 취지에 어긋나지 않습니다. '이 난제를 충분히 고민해봤고 남용하지 않는다'면 이건 별 문제 없을 것 같습니다. 편집장님이 말씀해주신 것처럼 이 문제에 흥미를 가진 폴리매스 유저 한 명이 나중에 이 난제를 증명해내 필즈상을 받을지 누가 알아요?

질문이 있어요.
1. '폴매가 나아질 것 같아서 기분이 좋다. ' 이것을 존댓말이 아니라고 봐야 하나요? 그냥 문장인 것 같은데요.
2. 1+1같은 계산 문제도 허용 가능한가요?
1~2번 모두 가능합니다! 앞으로 활동 기대할게요!
