In his book, The Spiritual Universe, the famous American scientist Fred Alan Wolf gives this amusing example: A quantum pot of water that no one is observing will behave according to the principles of physics, but if the experimenter intends to observe its boiling point, then even if it is now sitting on a block of ice it will be affected by the experimenter's will to boil it.
在《靈魂與物理》一書中，美國知名科普作者沃爾夫舉出一個有趣的例子：一個沒人觀察的「量子水罐」會依循物理定律來運作，但若實驗者有意要觀察它的沸騰狀態，哪怕水罐是放在冰塊上，它也會受到實驗者的意志驅使而沸騰！
