Chapter 120

[differential (excellence ★)]

Attribute: it can accurately calculate to 6 decimal places and run 5000 numbers at the same time. It can cover all the activities that need to be calculated in the steam age.

Description: if human beings have complete it, they may enter the era of information frenzy in advance and push modern science to a higher level!

……

Of course, there are not so many ifs in human history. Everything is inevitable driven by cause and effect.

Tang Zheng turned off the light curtain, opened the synthesis platform again, and looked at the synthesis formula of the differential machine.

Compared with the steam engine, it requires relatively simple materials, only a large number of gears, a small part of plastic and copper tubes, a thick stack of punch cards, and a crank rocker like an old slot machine.

It can form a differential machine.

Of course, the demand for this gear is a little too large.

A pocket differential requires at least 2W nested gears. What Tang Zheng needs at present is a super differential that can provide him with all kinds of information like a brain.

Millions of gear synchronization operations are required.

If you rely on yourself to make millions of gears, even if the synthesis station can produce millions of units per second, it will take at least ten days to produce millions of units.

Too much trouble, Tang Zheng directly chose 'online shopping'

At the current price, a virtual currency can only buy 1 large gear, 5 medium gears, or 10 small gears.

He spent nearly 400000 virtual coins and purchased a pile of gears.

There are less than 200000 deposits left in his pocket.

However, as the times become more and more advanced, making money is no longer a big problem for Tang Zheng.

As long as civilization goes up, the pocket is always full!

100W gears can not be put into the synthesis table at one time, but can only be made into gear towers in batches.

The so-called gear tower is a vertical bar stacked by multiple gears and a lightweight differential machine. It needs at least three gear towers, and each tower is responsible for calculating different data.

For example, Xiaoming's home is 100 meters away from the school. It took him half an hour to get to the school. What's his average speed on the road.

For this simple data, the punch card is used to input the data into the differential machine. The first gear tower is responsible for coordinating the distance, the second is the time, and the last gear tower can print the conclusion on the new punch card.

Of course, this is only the simplest data model. The more the number of gear towers, the more accurate the statistical results will be.

For example, the differential machine composed of ten gear towers can also include the wind force, road resistance, traffic light conversion, etc. when Xiao Ming sets out.

Once the final result is less than half an hour, Xiao Ming will be beaten up.

Of course, the significance of the existence of the differential machine is not to make the father laugh and the son laugh and the family live in harmony.

It has a greater role.

……

"Gambling?" Lan Lan took a small fan to fan for her master. At the same time, her two watery eyes showed a color of doubt. Her lips were as bright as cherry blossoms. "Is the differential machine used for gambling?"

"It's not so much for gambling as to say that people can only think of doing this at the beginning." Tang Zheng took out a high-rise gear tower with thousands of layers from the synthesis platform. Fortunately, there is a copper pipe in the center of the gear directly connected to the base, which connects them in series like a kebab, so as not to let the gears fall apart.

"The differential has existed in human history, but it has not been better optimized and promoted at the military level. The chip was born, and then the first generation processor. Facing the plug-in player such as electronic calculator, the differential can only withdraw from the stage of history." while carefully placing the gear tower in his hand, Tang Zheng explained.

"Ah! I see!" the little girl closed her hand gently: "because people in that era didn't understand the concept of information processing, the differential machine had just been invented. Everyone only used it to do some probability calculations, right?"

"Smart." Tang Zheng touched Lan Lan's head for a while. The praised latter smiled happily.

Just like when gunpowder was first invented, the science and technology tree of the people of Datang turned into fireworks.

It was later used in war and blasting.

At first, differential machine came out and did not get much attention.

Its most powerful information processing function has been ignored.

What is that?

Can I eat it?

Is gambling such a probabilistic data analysis, it is not fragrant?

After making money, he hugged two big girls with long hair. Isn't he happy?

This information processing is poor!

After a morning's production, Tang Zheng threw all the thousands of gear towers into the synthesis platform.

Excellent one star product takes two hours to make.

At noon, Tang Zheng cooked in person and made an exquisite meal according to the recipe in the atlas.

A big one and a small one are happy to eat. Even the little night lying next to them, they fly with a big Maotai bone in their arms.

After dinner, take a rest.

With the sound of a prompt, the spirit of Tang Zheng was shocked.

coming!

[Ding! Congratulations on your successful production of 'differential machine'! Civilization process in the steam age (2 / 10)!]

[as you are the first player in the world to make a 'differential machine', you will receive a random initiative Award - super expansion container * 10!]

[super flash tank (superior)]

Attribute: can increase the upper limit of your system's single item column to 10000!

Description: necessary for home travel! With it, you can empty the whole house!

……

This thing came just in time.

At present, the upper limit of a single grid of Tang Zheng's item column is less than 100, and the overall item column grid is only 5 rows, 10 grids per row.

Every time you get a large amount of resources, you can only connect with LAN LAN through remote transaction, which is very inconvenient.

Without a word, directly use the super expansion container and directly upgrade 10 item grids.

Now, he can load 10W pieces of materials to go out at one time.

More materials can be carried, which is conducive to the reclamation when he goes to other regions to expand his territory.

At the same time, the forum.

[the low-key giant is working again? What is the differential? Is there a big hand to popularize science for me who just graduated from primary school!]

[it seems to be a computer or something. Do you calculate probability?]

[lost!! low key giant computer?]

[what? Low profile giant already has a computer?]

[hiss... Can't you download the resources? I want the set of pictures of naoi Ning!]

[please! I want the codeless version of shuibuying!]

[where are a group of LSPs upstairs? With this advanced technology, what I want to do is download vulgar videos for the first time?! Oh, it's really a group of dog men! It's not like me. I just want an audio album of brother Yifan, Wuwu. Brother Yifan is really gentle and never bullies girls.]

[I think his sister also has the strength of violence / dog head / dog head]

[no, wait a minute. I have a relative in another district. I heard that when some big men in his district entered the steam age, they didn't have branch line tasks such as differential machines.]

[Oh! Where can the Lord's civilization branch mission be the same as that of mortals? What? You ask me why the low-key giant is the Lord? Before talking about this, I want to talk about the difference between the leaders in other areas and the low-key giant. First, they commit the crime of arrogance...]

[tune treasure, my superman!]

……

When arousing a heated discussion in the forum, Tang Zheng has taken out the super differential machine in the item column.

When millions of giant objects with gear structure fell to the ground, it was obvious that the ground shook three points.

With a height of two floors and an area of nearly 50 square meters, thousands of gear towers with metallic luster shine in the sun.

In addition, there is a vertical 0-9 digital circle at the front end of the gear, which is similar to the lock ring of the password box.

Looking at the metal guy in front of him with satisfaction, Tang Zheng opened the attribute atlas.

[super differential (excellence ★)]

Attribute: it can accurately calculate to 180 decimal places and run 150000 digital units at the same time. It can cover all the activities that need to be calculated in the steam age.

Description: if human beings have complete it, they may enter the era of information frenzy in advance and push modern science to a higher level!

Energy consumption: 1MW / h (1000kW)

……

Yes, the original differential machine atlas can only calculate 6 digits after the decimal point and the synchronous operation of 5000 digital units.

Under the structure of multi gear tower and its own attribute bonus, its function has been turned over 30 times!

It's just that the energy consumption is a little high. I want to drive this big guy.

At least ten steam engines of normal size are required to do work at the same time.

Such a big guy can't put it in the house. Tang Zheng can only temporarily place it in the leafy area in the forest in case of sudden rain.

This thing is definitely a brain level prop at this stage. When you look back, you'll build a house for it.

Turn your hands, take out the ten steam engines prepared in advance, and add coal mine and water.

The work wheel of each steam engine is connected through the mechanical arm.

Finally, it is connected to the interface at the back end of the differential.

"It's so beautiful, master." Lan Lan looked around the behemoth and touched it right and left. Her eyes were full of respect.

The differential machine is covered with the unique oily light of metal materials. It is a good smelling metal product, which has not been stained with the steam smell full of kerosene.

"It's not a flashy guy." Tang Zheng smiled and twisted the right crank rocker.

Press hard down.

"Click."

"Click."

The gears began to work, making a creaking sound of metal rotation.

"How can it be put into use?" Lan Lan asked curiously.

"Use this." Tang Zheng took out a stack of thick punch cards. One pile drilled irregular holes on the synthesis table in advance, while the other pile was brand-new cardboard, which had not left any trace on it.

"These punched cards are the information we need to input. For example, your shoe size."

"Ah... 2... 28 yards." Lan Lan seems a little embarrassed.

Because she has received a large amount of knowledge, she is much more precocious than ordinary girls.

The girl's foot size... She's really a little shy.

"Then let's use this punch card with 2 characters at the beginning and 8 characters at the end." Tang Zheng took out a card with only two holes and stuffed it into one side of the differential gear tower.

With the rotation of the gear, the punch card is slowly swallowed.

The little girl looked closely.

"Then, the shoulder width of your coat and the waist of your pants."

"Ah ah... Do you want to say this..." Lan Lan blushed and hesitated: "most... I've eaten a little better recently, a little bit... I've gained weight..."

Tang Zheng glanced at the delicate little girl with a speechless face.

Women are really a kind of creatures who care about their body. Even little Lori, who is only seven or eight years old, knows to pay attention to her image.

"This is for science."

"OK, ok..." the little girl bit her lips, closed her eyes and loudly reported her clothes size and trousers waist circumference: "however, then... My underwear size is..."

"Don't use this. It's about the same as the waist circumference." Tang Zheng calmly turned to draw the card, leaving LAN LAN with a red face.

What to do... It's embarrassing.

I really want to find a ground crack to drill in

Input the approximate dress size of the little girl into the differential machine from the left through the punch card.

Several punch cards were placed to the far right.

As the gears roll.

Soon, the brand-new cardboard on the right side was quickly punched and spit out.

Tang Zheng took it and looked.

"The difference machine gives a total of 18 prediction results for your height and weight."

"The first one is 115.784512 cm in height and 21.1 cm in weight..."

"No, no, don't watch!!!" the little girl took the punch card from Tang Zheng's hand, turned her back to Tang Zheng and threw it into her item column.

The big pupils trembled slightly, reflecting the shocking color.

This... What immortal machine is this

Good... Good accuracy

Recently, my food is a little good and I eat a little too much... I've gained more than 100 grams. Will Shifu mind

Don't think you're too fat, and then drive yourself out of the school

Tang Zheng didn't understand the little girl's state of mind at this time. She only saw her back to herself, and her delicate shoulders trembled gently.

Poor boy, maybe I have a cold.

"There are 1071 gear towers here. You can input 1071 different situations. The more data you input, the more accurate the results will be." Tang Zheng gently skimmed the exposed gear of the differential machine.

This cold thing composed of all metal has an unspeakable mechanical beauty, which always makes people feel an inexplicable love.

"In other words, it can even predict your whereabouts. As long as you input all aspects of your living habits, action trajectory and the state when you fall asleep that day, it has a great possibility to infer what you want to do the next day."

"This... So magical???" Lanlan turned around inconceivably, ignoring her shyness, and her bright eyes stared round.

"You should have heard of the Laplace devil."

"HMM." the little girl nodded her white forehead: "I've seen it in extracurricular science popularization before. It's a theory put forward by the famous mathematician Laplace: if a demon can know the position and momentum of all atoms in the universe, it can know everything that has happened, is happening and will happen in the universe."

"Yes, the principle of the differential machine is the same. The input data is like the known atomic momentum." Tang Zheng nodded with satisfaction, and the little girl's book was not read in vain.

"Master, you know so much! What a powerful duck!!" Lanlan's eyes flashed a little star.

Tang Zheng coughed and closed the atlas of [Laplace devil] without expression.

"However, there are only 1071 gear towers, and the results that can be predicted are limited. It mainly focuses on data analysis and information processing. It can help us intuitively convert the strength of each region into data that we can understand. The so-called knowing ourselves and the enemy is invincible in a hundred battles."

"Uh huh! Ah, by the way, master, what if... What we want to input cannot be expressed by data? For example... Emotions, such as likes and dislikes. How to analyze this?"

"It's also simple. Just digitize your emotions. Favor is 1, disgust is 2, hatred is 3, and happiness is 4. You just need to convert all the emotions that can be expressed into a series, and then show them on the punch card, and then enter the personality and habits between two or more people to get emotions that are closer to your true thoughts. For example, you like it This person, or hate this person, or what kind of emotional state, these can be simulated by the differential machine. "Tang Zheng said enthusiastically," come on, I'll give you a try. "

"Ah! No, no!!"

Lan Lan immediately shook her head in panic and stepped back. Her small mouth closed tightly, and her face was full of tension.

The tender throat rolled slightly and swallowed saliva quietly.

With a bit of awe in his eyes, he looked at the machines composed of gear towers in front of him.

Open

Are you kidding

This machine

I'm afraid.

LAN LAN is really afraid
