Recall Kepler, he was the one who created the Laws of Planetary Motion.
Kepler was an astronomer, but he was also an able geometer. His Laws of Planetary Motion arose from his interest in these two (till that time) distinct fields.
“Kepler is only one of many examples of the falsity of the idea that success in scientific research demands an exclusive absorption in one narrow line of study. Novel ideas are more apt to spring from an unusual assortment of knowledge – not necessarily from vast knowledge, but from a thorough conception of the methods and ideas of distinct lines of thought.”
