The Gulag Archipelago

God was there, too:

Nikolai Aleksandrovich Kozyrev, whose brilliant career in astronomy was interrupted by his arrest, saved himself only by thinking of the eternal and infinite: of the order of the Universe -- and of its Supreme Spirit; of the stars; of their internal state; and what Time and the passing of Time really are.

And in this way he began to discover a new field in physics. And only in this way did he succeed in surviving in the Dmitrovsk Prison. But his line of mental exploration was blocked by forgotten figures. He could not build any further -- he had to have a lot of figures. Now just where could he get them in his solitary-confinement cell with its overnight kerosene lamp, a cell into which not even a little bird could enter? And the scientist prayed: "Please, God! I have done everything I could. Please help me! Please help me continue!"

At this time he was entitled to receive one book every ten days (by then he was alone in the cell). In the meager prison library were several different editions of Demyan Bedny's Red Concert, which kept coming around to each cell again and again. Half an hour passed after his prayer; they came to exchange his book; and as usual, without asking anything at all, they pushed a book at him. It was entitled A Course in Astrophysics! Where had it come from? He simply could not imagine such a book in the prison library. Aware of the brief duration of this coincidence, Kozyrev threw himself on it and began to memorize everything he needed immediately, and everything he might need later on. In all, just two days had passed, and he had eight days left in which to keep the book, when there was an unscheduled inspection by the chief of the prison. His eagle eye noticed immediately. "But you are an astronomer?" "Yes." "Take this book away from him!" But its mystical arrival had opened the way for his further work, which he then continued in the camp in Norilsk.

Coincidence, or Providence?
