Einstein's Dreams - Alan Lightman [1]
Outside, the tops of the Alps start to glow from the sun. It is late June. A boatman on the Aare unties his small skiff and pushes off, letting the current take him along Aarstrasse to Gerberngasse, where he will deliver his summer apples and berries. The baker arrives at his store on Marktgasse, fires his coal oven, begins mixing flour and yeast. Two lovers embrace on the Nydegg Bridge, gaze wistfully into the river below. A man stands on his balcony on Schifflaube, studies the pink sky. A woman who cannot sleep walks slowly down Kramgasse, peering into each dark arcade, reading the posters in halflight.
In the long, narrow office on Speichergasse, the room full of practical ideas, the young patent clerk still sprawls in his chair, head down on his desk. For the past several months, since the middle of April, he has dreamed many dreams about time. His dreams have taken hold of his research. His dreams have worn him out, exhausted him so that he sometimes cannot tell whether he is awake or asleep. But the dreaming is finished. Out of many possible natures of time, imagined in as many nights, one seems compelling. Not that the others are impossible. The others might exist in other worlds.
The young man shifts in his chair, waiting for the typist to come, and softly hums from Beethoven’s Moonlight Sonata.

Suppose time is a circle, bending back on itself. The world repeats itself, precisely, endlessly.
For the most part, people do not know they will live their lives over. Traders do not know that they will make the same bargain again and again. Politicians do not know that they will shout from the same lectern an infinite number of times in the cycles of time. Parents treasure the first laugh from their child as if they will not hear it again. Lovers making love the first time undress shyly, show surprise at the supple thigh, the fragile nipple. How would they know that each secret glimpse, each touch, will be repeated again and again and again, exactly as before?
On Marktgasse, it is the same. How could the shopkeepers know that each handmade sweater, each embroidered handkerchief, each chocolate candy, each intricate compass and watch will return to their stalls? At dusk, the shopkeepers go home to their families or drink beer in the taverns, calling happily to friends down the vaulted alleys, caressing each moment as an emerald on temporary consignment. How could they know that nothing is temporary, that all will happen again? No more than an ant crawling round the rim of a crystal chandelier knows that it will return to where it began.
In the hospital on Gerberngasse, a woman says goodbye to her husband. He lies in bed and stares at her emptily. In the last two months, his cancer has spread from his throat to his liver, his pancreas, his brain. His two young children sit on one chair in the corner of the room, frightened to look at their father, his sunken cheeks, the withered skin of an old man. The wife comes to the bed and kisses her husband softly on the forehead, whispers goodbye, and quickly leaves with the children. She is certain that this was the last kiss. How could she know that time will begin again, that she will be born again, will study at the gymnasium again, will show her paintings at the gallery in Zürich, will again meet her husband in the small library in Fribourg, will again go sailing with him in Thun Lake on a warm day in July, will give birth again, that her husband will again work for eight years at the pharmaceutical and come home one evening with a lump in his throat, will again throw up and get weak and end up in this hospital, this room, this bed, this moment. How could she know?
In the world in which time is a circle, every
