“Your Imperial Majesty, this is the Qin 1.0 operating system we developed. The software for doing the calculations will run on top of it. That below”—Von Neumann pointed to the human-formation computer—“is the hardware. What’s on this paper is the software. The relationship between hardware and software is like that between the guqin zither and sheet music.”
He and Newton then spread open another scroll, just as large. “Your Imperial Majesty, this is the software for using numerical methods to solve those differential equations. After entering the motion vectors of the three suns at a particular moment obtained by astronomical observation, the software’s operation will give us a prediction for the suns’ subsequent motion at any moment in the future. Our first computation will calculate all the suns’ positions for the next two years. Each set of output values will be one hundred and twenty hours apart.”
Qin Shi Huang nodded. “Good. Begin.”
Von Neumann lifted both hands above his head and solemnly chanted: “As ordered by the great emperor, turn on the computer! System self-test!”
A row of soldiers standing halfway down the face of the pyramid repeated the order using flag signals. In a moment, the motherboard made of thirty million men seemed to turn into a lake filled with sparkling lights. Tens of millions of tiny flags waved. In the display formation closest to the base of the pyramid, a progress bar made of numerous green flags slowly advanced, indicating the percentage of the self-test that had been completed. Ten minutes later, the progress bar reached its end.
“Self-test complete! Begin boot sequence! Load operating system!”
Below, the light cavalry on the main bus that passed through the entire human-formation computer began to move swiftly. The main bus soon turned into a turbulent river. Along the way, the river fed into numerous thin tributaries, infiltrating all the modular subformations. Soon, the ripple of black and white flags coalesced into surging waves that filled the entire motherboard. The central CPU area was the most tumultuous, like gunpowder on fire.
But suddenly, as though the powder had been exhausted, the movements in the CPU slackened and eventually stopped. Starting with the CPU in the center, the stillness spread in every direction, like a sea being frozen over. Finally, the entire motherboard came to a stop, with only a few scattered components flashing lifelessly in infinite loops. The center of the display formation blinked red.
“System lockup!” a signal officer called out. Shortly after, the reason for the malfunction was determined: There was an error with the operation of one of the gates in the CPU status register.
“Restart system!” Von Neumann ordered confidently.
“Wait!” Newton stopped the signal officer. He turned with an insidious expression and said to Qin Shi Huang, “Your Imperial Majesty, in order to improve system stability, you should take certain maintenance measures with respect to faulty components.”
Qin Shi Huang grasped his sword and said, “Replace the malfunctioning component and behead all the soldiers who made up that gate. In the future, any malfunctions will be dealt with the same way!”
Von Neumann glanced at Newton, disgusted. They watched as a few riders dashed into the motherboard with their swords unsheathed. After they “repaired” the faulty component, the order to restart was given. This time, the operation went very smoothly. Twenty minutes later, Three Body’s Von Neumann architecture human-formation computer had begun full operations under the Qin 1.0 operating system.
“Run solar orbit computation software ‘Three Body 1.0’!” Newton screamed at the top of his lungs. “Start the master computing module! Load the differential calculus module! Load the finite element analysis module! Load the spectral method module! Enter initial condition parameters… and begin calculation!”
The motherboard sparkled as the display formation flashed with indicators in every color. The human-formation computer began the long computation.
“This is really interesting,” Qin Shi Huang said, pointing to the spectacular sight. “Each individual’s behavior is so simple, yet together, they can produce such a complex, great whole! Europeans criticize me for my tyrannical rule, claiming that I suppress creativity. But in reality, a large number of men yoked by severe discipline can also produce great wisdom when bound together as one.”
“Great First Emperor, this is just the mechanical operation of a machine, not wisdom. Each of these lowly individuals is just a zero. Only when someone like you is added to the front as a one can the whole have any meaning.” Newton’s smile was ingratiating.
“Disgusting philosophy!” Von Neumann said as he glanced at Newton. “If, in the end, the results computed in accordance with your theory and mathematical model don’t match reality, then you and I aren’t even zeroes.”
“Indeed. If that turns out to be the case, you will be nothing!” Qin Shi Huang turned and left the scene.
Time passed quickly. The human-formation computer operated for a year and four months. Subtracting out the time spent to adjust the programming, the actual processing time was approximately a year and two months. During this time, processing had to be stopped twice due to extremely bad weather in Chaotic Eras. But the computer stored the data at the time of each shutdown, and was able to resume calculations successfully after the pauses. By the time Qin Shi Huang and the European scholars ascended the pyramid again, the first phase of the computation was complete. The results precisely described the orbits of the three suns for the next two years.
It was a chilly dawn. The torches that had kept the motherboard lit through the night were extinguished. After the final calculation, Qin I entered standby mode. The turbulent waves over the motherboard settled into light ripples.
Von Neumann and Newton presented the scroll with the results of the computation to Qin Shi Huang. Newton said, “Great First Emperor, the calculations were completed three days ago. We waited until now to present the results to you because they show that the long night is about to be over. We’ll soon welcome the first sunrise of a long Stable Era, which will last more than a year. Judging by the orbital parameters, the climate will be extremely mild and comfortable. Please revive your empire and order everyone to be rehydrated.”
“Ever since the start of this computation, my empire has never been dehydrated,” Qin Shi Huang said in a huff, grabbing the scroll. “I’ve devoted all the resources of the Qin Empire to maintain the operation of the computer, and we’ve run out of stored supplies. For this computer, countless people have died of hunger, cold, and heat.” Qin pointed into the distance with the scroll. By the dim dawn light, they could see tens of white lines radiating from the edges of the motherboard in every direction, disappearing over the horizon. These were the supply routes from every corner of the empire.
“Your Imperial Majesty, you will find that the sacrifices are worth it,” Von Neumann said. “After mastering the orbits of the suns, Qin will develop by leaps and bounds, and will grow many times more powerful than before.”
“According to the calculations, the sun is about to rise. Great First Emperor, prepare to receive your glory!”
As if in response to Newton’s words, a sliver of red sun peeked over the horizon, bathing the pyramid and the human-formation computer in a golden light. A wave of joyous cries rose from the motherboard.
