核心畫面

Picture a path that leaves a point, goes all the way round, and arrives back at that same point — a closed loop you can travel again and again. Send a runner round it and it is a track; send an electric current round it and it is a circuit; send a judge or a tennis player round the same set of places year after year and it is still the same loop.

可以想成:一條從某個點出發、繞一整圈、又回到原點的路線——一個可以一再重複走的封閉迴圈。讓人繞著跑,它是跑道;讓電流更多收起可以想成:一條從某個點出發、繞一整圈、又回到原點的路線——一個可以一再重複走的封閉迴圈。讓人繞著跑,它是跑道;讓電流繞著跑,它是電路;讓法官或網球選手年復一年繞著同一批地點跑,它還是同一個迴圈。
