I! Pretending to Be Reborn, Director of Doomsday Hoax

The ancient technology has been reborn. In the extreme cold, the nuclear power difference machine of the Dragon Kingdom will shine!

"Let's go to the nuclear power Changlong R&D department!"

Xu Qiu took a step and left the Office of the Crisis Bureau.

It's time to witness a turning point in history.

The helicopter circled up, and the escort fighter jets were waiting around, protecting this man who represented the underground era of the Dragon Kingdom.

At the same time,

With Xu Qiu's permission, a piece of news gradually spread on major social media, and it quickly became the hot search list.

Hot search No. [-]: "Dragon Kingdom's difference engine is finally going to be developed. This ancient technology may be the greatest product of the extremely cold age!" Hot search No. [-]: "Dragon Kingdom's difference engine is a brand new design Invention, completely different from Babbage's Difference Engine!"

The third hot search: "What exactly is the difference machine! What are the advantages of Longguo's difference machine, and why do you dare to call it the backbone of the mechanical technology tree of the Extreme Cold Era!"

almost on.

One by one related questions were also topped the ranking list.

And the hottest of them all is a question.

"If the tolerances of the parts were small enough back then, could the differential engine defeat the electronic tube computer and be applied on a large scale?"

Time seems to have returned to more than 200 years ago...

Mechanics enthusiast, A Si, a mechanical genius who is only 12 years old, expressed his views.

"If the difference engine of the year succeeded in winning the computing field in terms of efficiency and speed,

Well, this will lead human science and technology to a wrong path,

Perhaps computer science in our current world is entering a new bottleneck, where the development of new technologies is slow or even stagnant...

If you want to know what the difference engine is, you can go to Du Niang.

What I can tell you is that the difference engine is a cumbersome and slow-moving machine.

Take Babbage's first-generation difference engine as an example. This giant can only handle three different five-digit numbers, and calculate several kinds of function tables.

There are only six decimal places for calculating the progress.

This difference engine has [-] small parts and weighs [-] tons!

It was not until ten years later that he improved the second-generation difference engine.

However, the second-generation difference engine can only automatically solve complex arithmetic problems with 100 variables, each number can only reach 25 digits, and the speed is one operation per second.

It can only store 1000 50-digit memory banks, relying on the meshing, rotation, translation, etc. between gears to perform digital operations!

The Difference Engine is a purely mechanically driven computer!

No matter how talented Director Xu is, to improve its efficiency and performance as a whole, it will never become as light and fast as the computers in today's world! Why?

Because there is no breakthrough in physical performance, everything is useless!

The difference engine is essentially a kind of computer specialized in functional calculations. Compared with the entire social industry, the fields in which it can be used are few and far between.

Its bulky size makes it even worse for its use,

So it is absolutely impossible to use it in any field on a large scale.

Because there are fewer fields of use, there will be fewer needs!

Unless research in the field of mathematics finally hits a bottleneck, improvements to the Difference Engine will come very late.

We all know that the way information is transmitted affects our daily lives,

If the physical performance of the Difference Engine had not improved, the way information was transmitted would not have changed.

The difference engine cannot undertake the information transmission task of today's electric power computer.

The transmission of information has a huge impact on our society, our technology, our civilization, and our life.

If computer performance does not improve, the development of the entire computer field and even the entire technology field will stagnate!

I understand your thoughts very well, I am also a mechanical enthusiast!

Of course, I also hope to see the difference engine applied to future machines, and become an important force for our Dragon Kingdom to form a technological monopoly over other countries!

Steampunk is a very good sci-fi aesthetics, however...but it is only limited to aesthetics!

For sci-fi fans like me, a technological system without any prospect of technological development is meaningless!

From the beginning of the design, the difference engine was driven by steam, driven by gears, to realize calculations. This backward and inefficient calculation method...

I admit that it may indeed be able to maintain its characteristics in the era of extreme cold, and will not lose its electrical performance like an electric computer.

However, its computing power is not enough to take on this important task..."

Ah Si is a mechanical genius specially recruited by Tsinghua University.

At only 12 years old, his understanding of mechanical structure and cognition of machinery has reached a terrifying level.

Even, with many mechanical experts who have been studying for decades, they have the power to argue!

Below, there are many replies from netizens.

[Anonymous user]: "Physically speaking, the performance of the differential engine cannot be broken through, and I am also disappointed with our country's differential engine... Efforts are in the wrong direction!"

[Eating sweet and sour fish today]: "I agree with Ah Si's point of view. If the difference engine is developed, then technology will develop horizontally, and the technology tree will be a little messy. The era of big steam has long passed, and it proves that Without backwardness, how could it be possible to restore the 'restoration'..."

[I love to eat children]: "A Si is right. This questioner asked a science fiction question!

Why is it called science fiction?Because, on the physical level, it is impossible for us to reach the level of 'tolerance is small enough', not to mention that we couldn't do it before, and we still can't do it now!Therefore, even if the difference machine has attracted the attention of Eagle Country, this direction will still be rejected.

Steampunk, I also love and yearn for it, however,

This is something that only exists in fantasy!

The efficiency is too low, technically and physically, it cannot be done! "

[Mechanic Old Bus]: "In those days, it was already incredible to be able to be accurate to 25 decimal places.

However, it is far from enough now!

A mechanical computer is just a machine after all. If you really want to make a fuss on the difference machine,

Then, we will fall into an endless cycle of making parts, not being precise enough, adjusting the precision and making parts again!

Looking at my name, everyone should know that I am a loyal fan of Babbage and a fan of the Difference Engine.

I have a deep understanding of the difference machine, and I know the shortcomings of this machine better than most netizens.

Low efficiency, bulky, easy to wear, difficult to manufacture, etc... Even if the difference engine is successful, it can only be partially invested in the scientific and military fields! Moreover, it cannot undertake the tasks of an electric computer. "

On the Internet, a number of mechanical enthusiasts are conducting popular science and expressing doubts about the difference engine.Netizens also became suspicious when they saw these remarks.

Is Longguo's difference machine really just a bluff?

At the same time, foreign media are also reporting on the difference machine of Longguo!

Most people don't know what the difference engine means or what it is.

The million-dollar V of the oil tank, the former mechanic of the National Aeronautics and Space Administration, Jack came out to popularize science.

"Everyone knows the news released by the Dragon Kingdom Crisis Bureau.

They said that the difference engine will be the backbone of the mechanical technology tree in the era of extreme cold!

So, let's first assume that the difference engine can be developed, what kind of impact it will have on the world...

My answer is,

Even if we make 033—a difference engine with comprehensive computing capabilities,

For this elite product of the era of the first industrial revolution, its influence will be extremely limited!

The root cause is that,

It is difficult to put this kind of complex crafted product into the assembly line production system.

The inability to mass produce is its biggest limitation!

Another reason is that,

If the calculation volume of the difference engine is to meet the needs of the industry, it must be bigger and bigger.

We must know that the reason why electronic computers can develop to the present level is that the industrial basis is that the silicon chips and transistors that support their operation can be made smaller and smaller.

But the difference machine, which relies on gears, springs and other parts to operate, does not have such advantages.

Therefore, I am very suspicious now that Longguo's rumor of something like a 'difference machine' is probably just misleading us, wanting our top management to waste energy on meaningless things! "Jack has a good reputation in the international machinery industry.

After these words spread, many people began to criticize Long Guo.

However, within Eagle Country.

After Mary saw the news, a sarcastic smile appeared on her face.

"Mrs. Mary, it seems that the difference engine of Longguo is about to be developed, shall we... continue?" asked a mechanic with a straight nose.

Mary looked sternly, and asked: "If you don't continue, do you expect the Dragon Kingdom to give you alms?"

The mechanic hesitated for a while, and finally said: "Mrs. Mary, many people are saying that the difference engine may not have such a big effect... Is Dragon Kingdom deceiving us?" "Idiot!"

Mary cursed.

"Ordinary people don't understand. As a mechanic, don't you know the potential of the difference engine?!"

Mary's eyes were blurred, and she was full of fascination for the greatest product of the mechanical age.

The steam engine drives the difference engine, which can be used as a programmable calculation tool!

Its functions include manipulating CNC lathes to produce high-precision parts, forming high-precision lathes...

Manufacture high-precision components to assemble chemical lasers.

Bessel Gaussian beams are transformed into high-precision axicon lenses, and then optical microscopes and photosilver with electron microscope-level resolution are manufactured!

And, manipulating atoms to manufacture nano-machines, using nano-machines to build difference machines, making VLSI-level integrated difference machines, and then creating artificial intelligence and mechanization of the human body. There are no obstacles to nuclear weapons!

Once, Mary even imagined using steam, the difference engine and other inventions of the Victorian steam age for space exploration.

Steam engines for trains, cars, and ships are all fine.

Although it is difficult for a steam engine to directly drive a rocket, the lift-to-drag ratio of a large rocket in reality can be overcome, but the efficiency is too low!
