Liu Zheng recalled that after the earliest incandescent lamps were developed, air existed in the glass.
Although this can also make the incandescent lamp shine brightly, it will quickly shorten the life of the tungsten filament in the incandescent lamp.
That's why they studied how to evacuate the air from incandescent lamps.
Later, the method of emptying the pipe was used. While maintaining the air extraction, the glass pipe of the exhaust port was burned and flattened.
Let all the air inside be exhausted.
This kind of processing method is not difficult for the current level of Long Yan's technology, but there will definitely be air remaining inside.
"This shouldn't affect the light of the incandescent lamp..." Liu Zheng said uncertainly.
In his memory, the earliest light bulbs went from air to vacuum, and finally found that injecting inert gas was the best option.
Currently, Long Yan has not yet researched the production of inert gases. Some of the waste gas produced in industrial areas does contain inert gases.
But it is extremely difficult to recycle these inert gases.
Finally, Liu Zheng decided on the research plan.
First, temporarily create an evacuated incandescent lamp.
For the production of this kind of incandescent lamp, the biggest difficulty is the bulb model.
But this kind of thing is no longer something Liu Zheng needs to worry about. He only needs to throw his ideas to the scientists, and they will figure out what to do.
However, after Liu Zheng told others his thoughts, he got an interesting idea.
Someone is actually studying the difference engine!
Since Newton and Leibniz discovered the operation of functions, many scientists have been studying how to simplify such complex operations.
Some people think about algorithms, and some people study problems.
Some people study machines according to this algorithm, intending to rely on the power of machinery to make such algorithms simple.
But the calculation of the function is very complicated.
Very few people can successfully research such a thing, but for the person in front of Liu Zheng, no matter whether his research is successful or not, at least the other person has created a model of the difference engine.
"Master Liu, please stay a moment and take a look at the difference engine I created."
Others said from the sidelines: "No one can create a function computing machine now, and Becky is no exception. Don't waste Mr. Liu's time."
"All the parts of the machine I built are made by myself. I can ensure that my machine can simply calculate functions, and can even use addition and subtraction to perform square calculations."
"I really don't understand. What's the significance of your calculation? Can we get an accurate calculation?"
"If you don't believe it, I can show it to you."
Everyone had sneers on their faces, and when they were about to speak, Liu Zheng interrupted them.
In the last generation, the advent of the difference engine did cause quite a stir. It was known as the computer of the steam age.
Before the advent of computers, many large-scale calculations were performed using this difference engine.
But this kind of thing is not that easy to use.
Liu Zheng looked at the difference engine and said, "Okay."
After receiving the permission, Becky had a bright smile on his face. Ever since he got inspiration from the cotton loom, he had been studying the difference engine day and night.
However, his research was not taken seriously in Britain.
So he decided to cross the ocean and come to Longyan to continue his research.
Everything from a gear to a screw on this machine was built by him alone.
Until now, the gear mixture that he has built looks as precise as a work of art. It has been assembled, and this is not a model, but a fully movable machine.
"Go ahead and show me how this machine works."
"Okay." Becky replied briefly. He took a breath and operated the difference engine to input a function.
On the other side, scientists who thought that such research would be impossible also recorded this function and began to calculate it.
Becky stared at the start switch of the differential engine, feeling uneasy, even though he had tested the operation of his machine before.
But now, the person watching this experiment behind him is a famous figure in Longyan—Liu Zheng!
The man who single-handedly directly promoted the current scientific progress!
He closed his eyes tightly and pulled down the lever that activated the differential engine.
The entire differential engine driven by steam power made a violent noise and smoke roared. When everyone saw this scene, they were worried that this thing would explode suddenly and couldn't help but hide behind it.
Becky explained: "Don't worry, this is normal. I use a steam engine as his power, that's why it makes such a noise. You don't have to worry at all."
"Please wait a moment, the difference engine will soon show you the inference results of this function."
Everyone had disbelief on their faces. Only Liu Zheng watched the tiny numbers on the difference machine scrolling little by little.
On the other side, the scientists who were betting against the difference engine were quickly deducing the results of their calculations.
He quickly filled up the endless sheets of rice paper, then threw them aside and took out another one to continue calculating.
As time passed by, the difference engine still kept ringing.
Finally there was a ding, and the terrible noise stopped.
The entire difference engine finally displays a series of numbers, which is the final calculation result.
At this time, the scientists who were betting against him were still making rapid calculations and did not publish their results.
If we talk about speed alone, the difference engine has won perfectly.
But this kind of operation cannot be a simple speed competition, what is more important is the result.
Mathematics is all about accurate results. Even if the process is complex, if the results are incorrect, such calculations will be meaningless.
After a while, the scientist also made his calculations public.
Everyone looked at these two calculation results and were slightly stunned.
Only the last digit is different between the calculation results of scientists and the difference engine.
Others had already verified the results of such calculations, and they were surprised to find that the results of the difference engine were accurate.
Scientists have lost to the difference engine in both calculation speed and conclusions.
Scientists were shocked to see such results, but they could only accept this reality.
After all, reality is reality.
If he loses, he loses. He has no arrogance towards Becky. The two of them just have different opinions.
What he didn't expect was that the Difference Engine would completely defeat him in terms of speed and accuracy.
He said to Becky sincerely and apologetically: "I'm sorry Becky, the difference engine you made is really capable."
Becky nodded slightly to accept the apology.
"It's normal for something like this to not be recognized again."
"At the beginning, I didn't believe that a difference engine could be built."
Everyone expressed their apologies and respect to Becky, and he harvested them one by one.
