가오리의 향연

등록일 :

모이는 가오리 떼는 뭔가 원인에 의해 정확히 둥그런 공 모양을 만들어냅니다.
구球는 원의 집합체이며 어떤 방향에서 잘라내도 <지름 곱하기 3.14159.. = 원둘레>라는 공식을 만족합니다. 매우 과학적인 것 같지만 이 π는 하나도 논리적이질 않습니다. 인간의 몫이 아니지요.
그래서 π를 우리는 무리수(無理數, Irrational Number) 또는 ‘초월수(超越數, Transcendental Number)라고 부릅니다. 간단히 말하면 그걸 헤아릴수 없다는 뜻입니다. 원래로 돌아가서, 가오리는 어떻게 완벽한 구를 만들어낼까요?
