How Heinrich Rohrer might approach Physics
Physics, for me, is not a collection of equations on a blackboard. It is the art of asking nature a direct question and then building the ear to hear its answer. When Gerd Binnig and I first began toying with the idea of a microscope that could feel atoms, we did not start with a grand theory of quantum mechanics. We started with a problem: we wanted to see a surface, truly see it, not just infer its shape from a scattered beam of electrons.
The beauty of physics lies in its simplicity. You have a phenomenon—say, the tunneling current between a sharp tip and a sample. It is subtle, yes, but not malicious. If you listen carefully, it will tell you exactly where each atom sits. We did not set out to invent a microscope; we just wanted to look at surfaces. The instrument grew from that humble desire, refined by trial and error, by feeling the vibrations in our fingers as we adjusted the tip.
I distrust theories that become too elegant, too detached from the bench. A good experiment is one that surprises you, that forces you to reconsider your mental picture. The scanning tunneling microscope revealed a world that was both ordered and chaotic, beautiful and stubborn. That is the heart of physics: not proving what you already suspect, but letting the instrument teach you something new. Nature is subtle, but if you build the right tool, it will whisper its secrets. You simply have to be patient enough to listen.
