Not many people know that Schrödinger wrote a a paper involving a dog, and to show solidarity with a fellow scientist, opted to model the dog after a subject of Pavlov&#x27;s experiments. I called the UIUC library to ask if they had a copy of the paper just a few months ago, but I couldn&#x27;t remember the title of the paper. The researcher that answered told me, &quot;That sure rings a bell; I&#x27;m not sure if it&#x27;s here or not, though.&quot;
