Here’s what you’ll learn when you read this story:In a study on mathematicians solving mind-melting problems, video footage showed behavioral changes right before someone had a “eureka” moment. It turns out that there is a way to pick up on the slight behavioral changes that give away when a “eureka” moment is about to happen. There was always a noticeable shift in behavior just minutes before the mathematicians would finally see where an answer was hiding. When applying the idea of eureka signals to mathematicians, the researchers had to consider the system of a mathematician. There are some parallels to an ecosystem here—mathematicians create what Tabatabaeian terms “notational niches” for different parts of the problem.
