Dinger, who was one of the pioneers of quantum mechanics, imagined putting a cat, a flask of Prussic acid, a radioactive atom, a Geiger counter, an electric relay and a hammer in a sealed box.

"薛定谔的猫"是最著名的未证实实验之一。1935年，量子力学的先驱之一，艾尔文·薛定谔提出了一个妙想：把一只猫、一个装有氢氰酸的烧瓶、一枚放射性原子、一个盖格计数仪、一个继电器和一把锤子一起放置到一个密封的盒子中组成一个装置，如果放射性原子衰变，盖格计数仪将探测到放射性，之后向继电器发送信号使其断开，从而释放之前被固定的锤子，锤子会将砸碎烧瓶并释放其中的氢氰酸，盒子里的猫于是被毒死。
