진 사람은 직업을 뺏기는 수학배틀!
허수는 대체 어쩌다 생긴 것일까요? 그리고 어디에 쓰일까요? 수학을 싫어해도 이 영상은 재미있을 겁니다...!
저는 고등학교 때 허수가 과연 어디에 어떻게 쓰이는지, 대체 이런 수를 왜 만들었는지 궁금했었습니다. 그리고 그 질문의 답을 찾아보려 했었는데 참 어려웠던 기억이 납니다. 이 영상을 통해 같은 호기심을 품으신 분들이 더 쉽게 알 수 있을 것 같네요.
Thanks to Dr Amir Alexander, Dr Alexander Kontorovich, Dr Chris Ferrie, and Dr Adam Becker for the helpful advice and feedback on the earlier versions of the script.
