For 50 minutes , he bounds across the stage , writing equations on the blackboard and rhapsodizing about the " amazing " and " beautiful " physics of rainbows .

50分钟内，他在讲台上蹦蹦跳跳，在黑板上写公式，狂热地赞美彩虹在物理上的“神奇”和“美丽”。

Perhaps we 'll sing hymns rhapsodizing our role as an ornate node in a vast network of new life that is spawning on top of the old .

自旧的生命系统中诞生出新生命的庞大网络，人类则成为其中一个华丽的节点也许我们还会为此高唱赞美诗哩！
