Einstein's Dreams

17 June 1905

The segments of time fit together almost perfectly, but not quite perfectly. On occasion, very slight displacements occur. For example on this Tuesday in Berne, a young man and a young woman, in their late twenties, stand beneath a street lamp on Gerberngasse. They met one month ago. He loves her desperately, but he has already been crushed by a woman who left him without warning, and he is frightened of love. He must be sure with this woman. He studies her face, pleads silently for her true feelings, searches for the smallest sign, the slightest movement of her brow, the vaguest reddening of her cheeks, the moistness of her eyes.

In truth, she loves him back but she cannot put her love in words. Instead, she smiles at him, unaware of his fear. As they stand beneath the street lamp, time stops and restarts. Afterwards, the tilt of their heads is precisely the same, the cycle

of their heartbeats shows no alteration. But somewhere in the deep pools of the woman's mind, a dim thought has appeared that was not there before. The young woman reaches for this new thought, into her unconscious, and as she does so a gossamer vacancy crosses her smile. This slight hesitation would be invisible to any but the closest scrutiny, yet the urgent young man has noticed it and taken it for his sign. He tells the young woman that he cannot see her again, returns to his small apartment on Zeughausgasse, decides to move to Zurich and work in his uncle's bank. The young woman walks slowly home from the lamppost on Gerberngasse and wonders why the young man did not love her.
