“Schrödinger’s cat” is a thought experiment created by Austrian physicist Erwin Schrödinger. The of the experiment was to show the flaws in a scientific theory suggesting that particles can only definitively if someone is observing them. In Schrödinger’s example, a cat is locked in a box with a radioactive substance and a container of . If the substance decays, it activates the poison and kills the cat. Schrödinger argued that if the decaying of the substance could not happen until someone observed it, then the cat would be both and dead until someone opened the box. Although Schrödinger’s goal was to show how strange this idea was, many people misinterpreted him. This misunderstanding has caused some people to believe that it is for a cat to be both alive and dead.

“Schrödinger’s cat” is a thought experiment created by Austrian physicist Erwin Schrödinger. The purpose of the experiment was to show the flaws in a scientific theory suggesting that particles can only definitively change if someone is observing them. In Schrödinger’s example, a cat is locked in a box with a radioactive substance and a container of poison. If the substance decays, it activates the poison and kills the cat. Schrödinger argued that if the decaying of the substance could not happen until someone observed it, then the cat would be both alive and dead until someone opened the box. Although Schrödinger’s goal was to show how strange this idea was, many people misinterpreted him. This misunderstanding has caused some people to believe that it is possible for a cat to be both alive and dead.

In 1975, a physics professor named Jack H. Hetherington wrote a paper about atomic behaviour. He was planning to submit this paper to a well-known scientific journal called the Physical Review Letters. However, when he was proofreading his work, he realized that he had unintentionally used the word “we” when writing about himself. Although this was a small , it was very problematic. The Physical Review Letters had a rule against the use of the word “we” unless the paper had multiple authors. Hetherington had written his entire paper on a typewriter, and he didn’t want to retype it all just to fix his error. Instead, he simply to credit another author. The author he chose was his cat, Chester. He changed Chester’s name to Felis Domesticus Chester Willard, shortened to F. D. C. Willard, to make it more . Hetherington’s plan worked, and his paper was published. Eventually, he admitted that the co-author was a cat, and even had Chester copies of the paper by making ink paw prints.
