“But my most honored Emperor, do you know what kind of army he has? Do you know what shape his empire is in? In the magnificent eternal city of Rome, even the river that flows through the city has been heavily polluted. Do you know the cause?”
“Military industrial production?”
“No, Great Emperor, it’s the vomit from Romans after their binge and purge feasts. When the nobles attend the feasts, stretchers have already been prepared for them under the tables. When they’ve eaten so much that they can no longer move, the servants carry them home. The entire empire has sunk into a quagmire of extravagance from which they cannot extricate themselves. Even if Caesar could organize an army of thirty million, it would not have the quality and strength necessary to perform this great calculation.”
“I am aware of that,” Qin Shi Huang said. “But Caesar is waking up and reinvigorating his army. The wisdom of Westerners is terrifying. You are not more intelligent than the men of the East, but you can see the right path. For example, Copernicus could figure out that there are three suns, and
“That’s why your empire must continue to develop, Great Emperor!” Von Neumann seized the opportunity. “If you can master the pattern of the suns’ movements, you will be able to make the most of each Stable Era, and also avoid the damage brought by each Chaotic Era. This way, your progress will be much faster than Europe’s. Believe us, we’re scholars. As long as we can use the three laws of motion and calculus to accurately forecast the movements of the suns, we do not care who conquers the world.”
“Of course I need to predict the suns’ movements. But if you want me to gather thirty million men, you must at least demonstrate for me how such calculations would be conducted.”
“Your Imperial Majesty, please give me three soldiers. I will demonstrate.” Von Neumann grew excited.
“Three? Only three? I can easily give you three thousand.” Qin Shi Huang glanced at Von Neumann, distrustful.
“Your Imperial Majesty, you mentioned just now the defect in the Eastern mind when it comes to scientific thinking. This is because you have not realized that even the complicated objects of the universe are made from the simplest elements. I only need three.”
Qin Shi Huang waved his hand and three soldiers came forward. They were all very young. Like other Qin soldiers, they moved like order-obeying machines.
“I don’t know your names,” Von Neumann said, tapping the shoulders of two of the soldiers. “The two of you will be responsible for signal input, so I’ll call you ‘Input 1’ and ‘Input 2.’” He pointed to the last soldier. “You will be responsible for signal output, so I’ll call you ‘Output.’” He shoved the soldiers to where he wanted them to stand. “Form a triangle. Like this. Output is the apex. Input 1 and Input 2 form the base.”
“You could have just told them to stand in the Wedge Attack Formation,” Qin Shi Huang said, glancing at Von Neumann contemptuously.
Newton took out six small flags: three white, three black. Von Neumann handed them out to the three soldiers so that each held a black flag and a white flag. “White represents 0; black represents 1. Good. Now, listen to me. Output, you turn around and look at Input 1 and Input 2. If they both raise black flags, you raise a black flag as well. Under all other circumstances, you raise the white flag.”
“I think you should use some other color,” Qin Shi Huang said. “White means surrender.”
The excited Von Neumann ignored him. He shouted orders at the three soldiers. “Begin operation! Input 1 and Input 2, you can raise whichever flag you want. Good. Raise! Good. Raise again! Raise!”
Input 1 and Input 2 raised their flags three times. The first time they were black-black, the second time white-black, and the third time black-white. Output reacted correctly each time, raising the black flag once and the white one twice.
“Very good. Your Imperial Majesty, your soldiers are very smart.”
“Even an idiot would be capable of that. Tell me, what are they really doing?” Qin Shi Huang looked baffled.
“The three soldiers form a computing component. It’s a type of gate, an AND gate.” Von Neumann paused to let the emperor digest this information.
Qin Shi Huang said impassively, “I’m not impressed. Continue.”
