Science is a game—but a game with reality, a game with sharpened knives … if a man cuts a picture carefully into 1,000 pieces, you solve the puzzle when you reassemble the pieces into a picture; in the success or failure, both your intelligences compete. In the presentation of a scientific problem, the other player is the good Lord. He has not only set the problem but also devised the rules of the game—but they are not completely known, half of them are left for you to discover or to determine. The experiment is the tempered blade which you wield with success against the spirits of darkness—or which defeats you shamefully. The uncertainty is how much of the rules God himself has permanently ordained, and how much appears to be caused by your mental inertia, while the solution generally becomes possible only through freedom from this limitation. This is perhaps the most exciting thing in the game. For here you strive against the imaginary boundary between yourself and the Godhead—a boundary that perhaps does not exist.

On September 5, the day they came for me, I was in my house on Ludwigstraße preparing some equations that Heisenberg had sent to me a few weeks earlier. Ever since July 20, when Hitler announced over the radio that the coup attempt had failed and that his life had been providentially spared, I knew that I didn’t have much time. My anguish grew as I listened to the subsequent news reports: the execution of Stauffenberg and of his close friends, the preparations for the trials in the People’s Court, and the massive wave of arrests that were made in the coup’s aftermath.
Well aware that I could easily be the next in line, I tried to remain calm. But when I learned that Heini—Heinrich von Lutz, my childhood friend—had been arrested, I knew for sure that my days were numbered. But what could I do? Flee Germany? Hide? Escape? We were right in the middle of the very worst months of the war. It would have been impossible. All I could do was wait, quietly, for the SS or the Gestapo to break into my house. If I was lucky.
Just as I had imagined, the thugs wasted little time. A few days later, the Gestapo arrived at my house, handcuffed me, and I was taken straight to Plötzensee.
On July 20, 1944, a select group of officials of the Wehrmacht, the Armed Forces of the Third Reich, aided by dozens of civilians, had made an attempt on Hitler’s life while the Führer was presiding over a meeting at his headquarters at Rastenburg, about six hundred kilometers east of Berlin. The leader of this group was Count Claus Schenk von Stauffenberg, a young colonel who had been wounded in the line of duty in North Africa. That day, Stauffenberg placed a pair of bombs in a briefcase, which was then deposited underneath the Führer’s desk. Stauffenberg waited for the bombs to go off, the signal for the coup to begin, the coup that would put an end to the Nazi regime and, possibly, the entire Second World War.
The tiniest, most infuriating logistical error foiled Stauffenberg’s plan. Either one of the bombs hadn’t been activated or the suitcase had simply been placed too far from where Hitler had been sitting. The Führer escaped with a few scrapes and not a single one of the high commands of the party or the army was seriously wounded. Despite the failure of their first operative, the conspirators fully intended to move ahead with their plan, but by the early hours of the next day the Nazis had regained control of the situation. The main orchestrators of the coup—Ludwig Beck, Friedrich Olbricht, Werner von Haeften, Albrecht Ritter Mertz von Quirnheim, and of course, Stauffenberg—were detained and killed that night in the general headquarters of the army, on the Bendlerstraße in Berlin. Hundreds of others were quickly arrested following the strict orders of the Reichsführer-SS and the new minister of the interior, Heinrich Himmler.
