hair. He always wore a shabby corduroy jacket, the shoulders of which were covered with a white layer of dandruff. Unlike many of his colleagues, Little Red Riding Hood was adored by his students. And while he took them seriously, and stimulated their intelligence with complicated assignments, the affection was not mutual. Little Red Riding Hood especially disliked students who challenged what he said.
    He had a particular aversion to the two young men who stood blocking the entrance to the lecture theater every morning. Their arrogance was legendary and their friendship was the subject of gossip even among the lecturers. They were said to love physics even more than they loved each other, and they fought over it with the passion of rivals. Little Red Riding Hood could not bear listening to their bragging conversation. Their backs were far too straight as they stood there surrounded by a circle of listeners, reciting formulae like the verses of a libretto, ordering the universe with conductors’ hands. Every now and then Oskar would turn his head to draw on one of his Egyptian cigarettes, doing so with an affectation that stirred his audience into nervous movement.
    The entire faculty had long since been made acquainted with Oskar’s view that the world was a finely spun web of causalities, with a hidden pattern that could only be deciphered either from a great distance or from up close. Recognition of the pattern, he intoned, was a matter of being at the right distance, and was therefore possible onlyfor God and for quantum physicists. Normal people remained in the middle distance, blind to the nature of things.
    Sebastian, who always spoke a little less loudly and also more slowly, called his friend a despicable determinist. He claimed not to believe in causality himself. Causality was, like space and time, a theoretical problem of cognition. To provoke Oskar and everyone around them, he cast doubt on the validity of empiricism as a method of establishing scientific findings. A man who stands by the river and watches a thousand white swans swim by cannot conclude that there are no black swans. Therefore physics is ultimately the servant of philosophy.
    Little Red Riding Hood pushed past the arguing students impatiently. It was impossible to give a lecture any longer without hearing their intrusive voices. Sometimes he looked up grumpily from his notes, thinking that their whispering would drive him to the brink, only to realize that Oskar and Sebastian were not even present.
    But they were very much present on the day that Little Red Riding Hood set a problem on dark energy, which could be solved only by the assumption of an Einsteinian constant that was not a constant. The next week, Oskar and Sebastian were not standing before the doors when Little Red Riding Hood arrived, but already sitting at their usual places, looking him in the eye. He summoned them to the board even before he had reached the lectern. They rose in unison. Oskar went to the right-hand side of the board; after a second’s hesitation, Sebastian went to the left. They flung their frock coats over their shoulders, and each held his with one hand as the other hand scratched frenziedly with a piece of chalk on the board. They wrote like men possessed: Oskar from the right and Sebastian from the left. The lecture theater was silent apart from the squeak of chalk that accompanied the growth of the equation. When their hands met in the middle of the bottom line, all fell still. A few faces in the auditorium cracked into smiles. Oskar completed the final lambda and clapped his hands together to shake off the chalk dust. Little Red Riding Hood was standing behindthem looking at the panorama of equations with his mouth half open, like someone gaping at an impossibly beautiful view. Oskar turned around and tapped him on the shoulder with the tip of his finger, as if he were striking a triangle.
    “Do you know what we have just proved, Professor?”
