In your own words, describe the breakthrough the physicists have. How does Dr. Banks connect this principle to Heptapod B?

The physicists have a breakthrough with Fermat's Principle of Least Time. This principle states that the route that a light ray takes is always the fastest possible. However, the word "least" is misleading. Really, the light ray follows an extreme path: it either absolutely maximizes or minimizes the route it takes. In mathematics, a minimum and maximum share the same properties and are described the same in equations. While studying the heptapods' writing formation, Dr. Banks realizes that the very first stroke was involved in several following...
