실제상황: 10명 더 걸었다고 무너질 듯 흔들린 다리!

반딧불이들이 모두 다 같이 깜박인다? 메트로놈이 모두 주기가 맞아진다? 우리가 달의 같은 면만 볼 수 있는 이유는? 목성의 위성 3개가 완벽히 1:2:4로 공전하는 이유는? 그리고 영국의 다리가 무너질 뻔한 현상에서 밝혀내는 동기화의 과학 이야기. 이름, 용어 수정 크리스티안 호이겐스 (수정) 크리스티안 하위헌스 (네덜란드 발음) 자막수정 11:21 - “지금처럼 공전이 자전보다 빨라 앞쪽을 보려하면 공전을 느려지게 만들어 고정시키고” (수정) 지금처럼 자전이 공전보다 빨라서 앞쪽을 보려 하면 자전을 느려지게 만들어 고정시키고

11:28 - “만약 위성이 너무 천천히 공전하면 반대로 공전을 빠르게 만들어 조석적으로 고정시키는 거죠.” (수정) "만약 위성이 너무 천천히 자전하면 반대로 자전을 빠르게 만들어 조석적으로 고정시키는 거죠." Thanks to Prof. Steven Strogatz. 많은 내용이 교수님의 저서 "Sync"와 교수님의 2004 TED talk에서 왔습니다. He is a giant in this field, and has literally written the book on chaos, complexity, and synchronization. It was hard to find a paper in this field that Steven (or one of his students) didn't contribute to.
