"Of course I need to predict the movement of the sun, but you asked me to gather an army of thirty million, and at least show me how this calculation works." Qin Shi Huang waved his robe.

"Your Majesty, please give me three soldiers, and I will demonstrate them for you." Von Neumann stiffened his spine and smiled.

"Three? Just three? I could easily give you three thousand. Qin Shi Huang looked suspicious, and his narrow eyes glanced at von Neumann.

"Great Your Majesty, you have just mentioned the shortcomings of the scientific thinking of the Orientals because you do not realize that the complex universe is actually made up of the simplest units. All I need is three, Your Majesty. Von Neumann affirmed.

Qin Shi Huang waved his hand gently, and immediately three young and energetic soldiers trotted over, their every move was extremely similar, like three programmed machines.

"I don't know your names," Feng. Neumann looked at the first two soldiers, patted them on the shoulder, and said, "You two are responsible for the signal input, so let's call it 'into 1' and 'into 2'." He raised his hand again, pointing at one of the remaining soldiers, "You, responsible for the signal output." Let's call it 'out,'" he said, holding out his hand to the three soldiers, "and then stand in a triangle, with the top of the exit and the bottom of 1 and 2." ”

"Hmph, why don't you just let them attack in a wedge formation?" Qin Shi Huang was quite contemptuous of these moves.

Newton's hand sometime appeared in the hand of a six-foot-long flag, three white and three black, grasped in his hand, handed to von Neumann, and he handed three soldiers two flags, one black and one white, after the soldiers each held a black and white flag in their left and right hands, von Neumann said: "White represents 0, black represents 1." Okay, now listen to me, out, you turn around and look at into 1 and into 2, if they all raise the black flag, you raise the black flag, and in other cases you raise the white flag, there are three kinds of situations: into l white, into 2 black; into l black, into 2 white; 1 and 2 are white. ”

"I think you should change the color, the white flag represents surrender." Qin Shi Huang frowned, a little displeased.

"Get up and running now! Into 1 into 2, each of you will raise the flag at will, okay, lift! Okay, lift again! Raise! But watching his results begin to unfold, von Neumann, who was highly excited, did not hear, let alone tell all kinds of orders.

Into the first and second began to raise the flag.

Black and black.

White and black.

Black and white.

"Out" have made the right choice, black, white, white.

Nothing goes wrong.

"Very good, running correctly, Your Majesty, your soldiers are smart!" Von Neumann applauded.

"Fools can do this, can you tell Lian what they are doing?" Qin Shi Huang looked very puzzled.

"These three people make up the components of a computing system, which is a type of door component, called 'and door'." Von Neumann explained, pausing for Qin Shi Huang to ponder the implications.

"I'm depressed enough, okay, go on." Qin Shi Huang's expressions disappeared.

Von Neumann looked at the soldier holding the black and white flag: "Let's build the next part." You, out, as long as you see one person in 1 and 2 raising a black flag, you raise a black flag, and there are three combinations of this situation - black and black, white black, black and white, and the remaining one situation - white and white, you raise a white flag. Do you understand? ”

"Understood." Izuku replied.

At the same time, the three of them began to wave the flag, and the black and white continued to rise and fall, and they all reacted correctly.

"Good boy, you are so smart, you are the key to the correct operation of the door parts, do a good job, the emperor will reward you!" Let's start running: lift! Okay, lift again! Again! Great, it's working properly, Your Majesty, this door part is called or door. ”

In the end, von Neumann made the three soldiers become the "AND Gate", "OR Gate", "XOR Gate", "Same or Gate" and "Three-State Gate" in computer theory, and let the two soldiers form the most basic NOT gate, and every time "out" raises the flag opposite to the color of "in".

Von Neumann bowed his head to Qin Shi Huang, who had a slight understanding, and said, "Now, Your Majesty, all the door parts have been demonstrated, isn't it?" Any three soldiers can master it after an hour of training. ”

"Don't they need to learn more?" Qin Shi Huang asked.

"No, we're going to build 10 million of these gate parts and combine them into a system that can do the calculations we need to solve the differential equations that predict the movement of the sun. This system, we call it...... Well, it's called ......," von Neumann pondered.

"Computer." The blue cat interjected.

"Ahh Von Neumann was overjoyed, smiling, and even extended a thumbs up to the blue cat, exclaiming: "The computer, the name is good, the whole system is actually a huge machine, the most complex machine ever built!" ”

In an instant, three months passed.

What appeared in front of the audience's eyes was an incomparably vast square array, dense and very small, but when I zoomed in on the camera and continued to scan vertically and horizontally, I found that these were all Great Qin soldiers.

The flock of flying birds stumbled past the square array, but was knocked away by the sky-rushing blood.

As the camera zooms out, the people grow smaller, and finally it's just a tofu block on the ground, and Qin Shi Huang, Blue Cat, von Neumann, and Newton stand on the platform at the top of the pyramid, which is full of elaborate stargazing instruments, not much different from the platform of Mozi Station.

"Your Majesty, your army is truly unparalleled in the world, and such a complex training has been completed in such a short time." Von Neumann looked extremely admiring.

"Although it is complicated as a whole, what each soldier has to do is very simple, and it is nothing compared to the previous training to crush the Macedonian phalanx." Although Qin Shi Huang's expression did not change, he could know how proud he was when he pressed the hand on the sword.

"God willing, too, for two such long epochs." Newton sighed.

"Even in the Age of Chaos, my army is still trained, and in the future, they will complete your calculations in the Age of Chaos." Qin Shi Huang glanced at the Great Qin soldiers in array, full of arrogance.

"Your Majesty, then, give your great order!" Von Neumann's body trembled and shouted loudly.

Qin Shi Huang's jaw.

At this time, a soldier trotted over, grabbed the long sword that symbolized power, and pulled it hard, and then Qin Shi Huang put it on the hilt of the sword that was pulled out, pulled it out, and shouted at Qingcang: "Become a computer queue!" ”
