In time, all of science will come to be a continuum of description, an explanation of networks, of principles and laws. That’s why you need to not just be training in one specialty, but also acquire breadth in other fields, related to and even distant from your own initial choice. Keep your eyes lifted and your head turning. The search for knowledge is in our genes.
In science and all its applications, what is crucial is not that technical ability, but it is imagination in all of its applications.
