Chen makes the following analogy to the information field: "the bandwidth of momentum" is like a slot for receiving letters. Because there are countless information waves floating through the air, most people's minds are a jumble, with many messages crammed in simultaneously in the same slot.
陳國鎮比喻，「動量的寬度」就好像是一個收信的閘口，因為宇宙中本就有無數的信息波在漫天飛舞，一般人心猿意馬，一個個念頭一閃而逝，好像一封信剛看了一行又急著拆另一封，收進來的信息自然是短暫的、片斷的。
