Regarding the toxicity of mercury, Li Yuanjia did not go into too much detail.
He could mention things without evidence, but he would never "swear" or guarantee anything. The only thing he could do was to remind Han Cheng several times to take precautions when doing experiments with mercury.
I have said too much and there is no good reason.
After all, even in the Tang Dynasty, Li Yuanjia could not escape the uniqueness of medicine compared with other sciences, that is, it takes a long time and a sufficient sample size to prove.
Among the major disciplines, medical certification is probably the most difficult.
Because of the ubiquity of individual differences, it is difficult for any single case, or even dozens or hundreds of cases, to explain the problem. There must be a sufficient number to prove it. For example, if a woman gives birth to a child too early, it will affect her health and life span.
The thousand cases Li Yuanjia counted alone may not be able to convince the Tang Dynasty's top brass, let alone the common people. After all, how can a fixed mindset formed over hundreds of thousands of years be so easy to change?
There are countless similar things in human history.
Not to mention anything else, it is just a yapian. It has been used as a miracle drug to treat diseases in Europe and North America in the 19th century. In the medical field, it almost has the same "noble" status as brandy and leeches; another example is
Tobacco, even in the first half of the 20th century, many doctors still swore that smoking was good for health. It was not until Europe began a large-scale investigation involving hundreds of thousands of people that it was finally determined that smoking is harmful to the human body...
…
That's too far.
As a mature doctor, Li Yuanjia certainly understands this truth, so he will warn Han Cheng and others and order them to take precautions when using mercury. However, the reason can only be explained by "it seems in the book", and it is impossible to directly explain it.
Give a very definite conclusion.
"In this life, I will be stable!"
After secretly lamenting the difficulty of his survival, Li Yuanjia waved his hand and said: "Okay, everyone else has dispersed... Han Cheng, come with me, let's talk about this mercury thing."
"Yes, Your Majesty!"
Everyone else bowed and saluted, looking at Han Cheng with a hint of envy in their eyes.
This tone obviously means that he values this boy very much... no, it should be said that he values the glass workshop and this mirror very much! But the others didn't think much about it. After all, everyone now knows the vast "money" scene of glass, and
I know that although the reputation of the glass in Prince Han's Palace is not good now, it is because of insufficient production. Once all the windows in the palace are replaced in the future, Han Cheng and the others will be very prosperous...
…
While Li Yuanjia and Han Cheng were discussing the possibility of using mercury to make mirrors in the house, Zhang Jianzhi was also continuing to discuss with Wang Pu in high spirits in the... no, it should be said to be the imperial court's turning workshop now.
Assembly line problem.
"Mr. Wang, I still don't understand something!"
After visiting the entire assembly line, Zhang Jianzhi frowned and asked in confusion: "There are still so many people, and the tools are still the same. Why use this...assembly line, right? You can make more in this way."
How about several times the car rolled over? This...isn’t this too strange?"
"Haha, isn't it weird?"
Perhaps because he had seen Zhang Jianzhi's problems too many times, Wang Pu laughed and said with a relaxed expression: "To be honest, when I first heard the king talk about the assembly line, I also felt... ahem, it felt strange.
!But later, when I built it completely according to the king’s order, and saw the carpenters making the tenth rollover with my own eyes, I completely understood it!”
"Oh? What's the point?"
Frowning his brows, Zhang Jianzhi quickly asked.
"Well..."
After thinking for a while, Wang Pu took a deep breath and said: "In my opinion, there are two main points. One is that everyone focuses on making one component. In this way, they will become more skilled and faster... The second
In other words, one person's energy is limited, and each of us is. Doing only one thing can make everything easier, not only making those parts, but also assembling these parts... Xiaolang
Sir, do you understand?"
When he finally asked this question, Wang Pu couldn't help but scratch his head.
In fact, although he now knows the assembly line of the turning workshop very well, when it comes to the principles, Wang Pu always feels that he still has not understood these words thoroughly.
To put it bluntly, it means knowing it but not knowing why.
So after saying these words, Wang Pu couldn't help but sigh: "Oh, it would be great if the king was here, I can definitely explain this matter..."
If Li Yuanjia heard what Wang Pu was thinking at this time, he would definitely curl his lips and reply to him: "Don't worry, your king and your level...well, it should be a little higher than your level, but that's all."
!”
Li Yuanjia, who has never been on an assembly line, understands this thing purely on paper.
The key is that because rolling over is so simple, the assembly line is also extremely simple. Even someone like Li Yuanjia, who has only heard of the concept but has never worked on any assembly line, can create it.
But in fact, any worker from the 21st century should do much better than him.
Li Yuanjia was like this, not to mention Zhang Jianzhi who just watched it once and for all - don't think of the assembly line too simply, otherwise Ford had already built a car assembly line in the early 20th century. Why are there so many countries?
The production of some small things is still a small workshop-style production method, and it has lasted for several decades?
This thing is really not as easy as imagined.
At least for Zhang Jianzhi, who lived in the thirteenth year of Zhenguan, it was impossible to fully understand it after just listening to Wang Pu's words and looking at the turning workshop.
So after frowning and thinking hard for a moment, he asked seriously: "Mr. Wang, can you allow me to stay here for a few days for advice?"
"Ah? Don't you need to study, young man?"
After being stunned for a moment, Wang Pu asked in surprise.
In his opinion, the reason why Mr. Zhang Xiaolang came to the car-turning workshop was just out of curiosity. Like many officials who came before, he just wanted to take a quick look. Why did he have to stay a few more days after hearing what he meant?
Think clearly? What about Taixue’s studies? Isn’t it like picking up sesame seeds and losing the watermelon?
"Haha, I just got my dressing leave!"
After taking a deep breath, Zhang Jianzhi quickly explained: "One month is enough for me to understand this assembly line."
"this……"
Wang Pu frowned and hesitated.
This overturning workshop was built by Prince Han's Mansion. To put it bluntly, it was the credit of him and Chen Mu. Therefore, after the previous official was transferred, there was no problem in bringing someone over to take a look. Everyone would give it face.
.
But if Zhang Jianzhi wanted to stay for a few more days, it would not be appropriate.
Seeing the troubled expression on his face, Zhang Jianzhi raised his eyebrows and asked, "Mr. Wang, is it inconvenient?"
"Well, a little bit."
After hesitating for a moment, Wang Pu nodded and said with a wry smile: "Now that this place is under the control of the imperial court, my words are not particularly useful. But Xiaolangjun, if you just want to understand the principle of the assembly line, there are actually a few more
