At the beginning of Part 1, Section 3, what does Fred know about Professor Flowerdew? What does Flowerdew know about Fred?

After climbing a narrow stairway and walking along a corridor whose walls were covered with photographs, the professor asked Fred what he knew about him. Little to nothing, said Fred. The professor, however, knew Fred to be a "bright fellow" who came from a rectory family. Fred, who stammered his pleasure at being noticed by the professor, said his next goal was to study under Wilson and learn his methods. He confessed his excitement at having seen Rutherford in the very building where they sat, the Cavendish (where it is rumored the physicists made equipment out of cardboard).
