Two people enter, and then some time later, three emerge. The physicist says, "The measurement wasn't accurate." The biologist says, "They have reproduced." The mathematician says, "If now exactly one person enters the house then it will be empty again."

They're designed to show us that these academic disciplines look at the world in very different, perhaps incompatible ways.
Instructive: Phase transitions in physical systems, like that between water vapor and ice, can give insight into other scientific problems, including evolution.WikipediaThere's some truth in that. Many physicists, for example, will tell stories of how indifferent biologists are to their efforts in that field, regarding them as irrelevant and misconceived. It's not just that the physicists were thought to be doing things wrong. Often the biologists' view was that (outside perhaps of the well established but tightly defined discipline of…
