Chapter 251: Popular Majors

The most solemn festival of this era has just passed, and people are still talking about the highlights of the Lantern Festival, among which the magic performed by Wang Yunzhi is naturally also a focus.

As for Liu Guo's report, it has drawn people's attention to the new term "chemistry".

"Brother, you are very knowledgeable, do you know what 'chemistry' is all about?"

"Ahem, this 'chemistry', as far as I know, is an untold secret of Taoism. The Tang Dynasty admired Taoism, Taoism refined the art of Dan, and it is said that the bearded guest is a Taoist heir, so it can be seen that it is not surprising that the Tang Kingdom is proficient in Taoist Danshu. ”

"I see! Brother Tai has a point. ”

This is a conversation between passers-by A and B, and in fact, there are all sorts of far-fetched arguments around the new word "chemistry".

On this day, Mao Geng was holding a meeting in the conference room, and the topic of the meeting was the plan for electric lighting.

Because of the Lantern Festival party, this electric light is no secret, but there is still some controversy among the traversers about whether it is practical.

"This bamboo charcoal filament lamp, the life span is only a thousand hours, six hours a day, will be able to light for half a year, hehe, it was originally a durable light bulb, but it turned out to be a consumable. I think it's better to wait until the tungsten wire is pulled out before turning on the light. Before that, the problem of electricity, the problem of power transmission, added up to definitely a system engineering. When the tungsten wire is pulled out, it is estimated that there are mature solutions to the electricity problem and the power transmission problem, and it is not too late to turn on the electric lights at that time. ”

It was Zhao Yuchun who was talking about it, Mao Geng looked at the guy who wanted to do everything in one step, and he didn't know how his father could take such a homophonic name with "stupid", it was obvious that Zhao Yuchun was not stupid, but he would seem too aggressive every time. Someone once ridiculed Mao Geng's name for being similar to "Mao Keng", Mao Geng himself has no taboo at this point, considering that there is a star whose name in later generations is also homophonic with "stupid", but this does not prevent Li Yufeng from having unlimited glory.

"What's wrong with the bamboo charcoal wire lamp! Edison in 188o after the bamboo charcoal wire lamp, until 19o9 Curricci to understand the tungsten wire drawing process, until 191o later, the bamboo charcoal wire lamp was gradually replaced by tungsten lamp, the history of bamboo charcoal wire lamp used for 30 years. As for the consumables that Team Leader Zhao said, what's wrong with selling consumables! I think it's good to sell consumables, and those who sell consumables in later generations have made a lot of money, at least I, a teacher, am very envious of people selling consumables, hehe! ”

Qian Airu felt that it would be good to have bamboo charcoal wire lamps in this era, and Mr. Qian imagined that when Edison was selling bamboo charcoal wire lamps to make money, he counted the money and counted his hands cramps, so he felt that this process must not be omitted.

Mao Geng felt a little ridiculous, but the black-hearted capitalists of later generations were like this. For example, even 4G technology is mature, and the monopolist is still making money on 2G mobile phone services, and then 3G mobile phones are belated, and when 4G is commercialized, 5G technology has actually passed. This strategy seems to have been carried forward in the Song Dynasty.

So Mao Geng asked:

"Old Gu, look, when can you pull the tungsten filament out?"

"It's hard! After He Chi'an went to Lin'an, he contacted Xin Qiji, and found the black stone in Dayu, Jiangxi, that is, tungsten ore, which is not difficult, and the history of Dayu tungsten ore can be picked up casually, He Chi'an is of Minmetals, if you don't know the large surplus tungsten ore, then it is really impossible to say. The problem is that it is not difficult to obtain tungsten trioxide from tungsten ore roasting, but it is best to reduce tungsten trioxide into tungsten metal by hydrogen, which requires electrolysis. Also, no one has ever done tungsten wire drawing, and it is estimated that it will take three months to explore the drawing process. Moreover, Kulich's simple tungsten wire is still not good, it seems that some oxide needs to be added to finally make a tungsten wire that does not sag, in 19o9 Kurich pulled out tungsten wire, but it was not until 1922 that the tungsten wire did not sag, which is not a small difficulty. ”

It is said that in later generations, Jiangxi Dayu is known as the "world's tungsten capital", and He Chi'an is of course familiar with it.

But the tungsten ore in Dayu is purely accidental, for thousands of years, black stone can be seen everywhere in Dayu Xihua Mountain, but the locals do not know that it is precious tungsten ore. Until 19o6, Wu Liheng, a German pastor of the Catholic Gospel Church in Dayu County, went to Xihua Mountain to watch Qingyun Temple, and now everywhere he goes, there are black and bright stones. So I picked up a few more pieces and brought them back to the church. The following year, Wu Liheng returned to China with stones, and it was determined that these ores contained a rare metal - tungsten.

Since then, the Blackstone has been exported to Germany and other countries around the world.

However, in the era of the Great Song Dynasty, it was not called Dayu, but "Dayu", so He Chi'an took some trouble to find the black stone in Dayu - that is, tungsten ore.

However, when you find tungsten ore, you only have raw materials, and you have to admit that there is still a lot of distance from pulling out the tungsten wire.

"Damn! Lao Gu, it's not so difficult! Don't forget, we are traversers, and we can take shortcuts in everything. Zhao Yuchun thinks that Gu Yongqiang's guy is deliberately exaggerating the difficulty.

Lin Lishi pouted and said:

"I said Team Leader Zhao, we can't look at the problem from the perspective of a farmer entrepreneur, the technology of the cottage is easy, you may be used to the cottage, and you think that the technology is like that. This is also my professional category, Lao Gu is not deliberately exaggerating the difficulty, powder metallurgy is still difficult, the theory is simple, and the process has to rely on a little bit of exploration. I'm still waiting for tungsten metal to be smelted earlier, tungsten metal is a good thing, and I still point to it to produce high-strength alloy steel. ”

Zhao Yuchun's face suddenly felt a little unbearable, and when Lao Qiu saw it, he immediately interrupted:

"Okay, okay, let's not talk about tungsten for now. I didn't put it in advance. ”

Today's meeting made Zhao Yuchun stir up, obviously a little crooked, and now when I see Zhao Yuchun deflated, I think you deserve it. Lao Qiu then got back to business:

"Since history proves that the life of bamboo charcoal filament bulbs can reach 12oo hours, ordinary people save a little use, almost a year, commercial use is no problem at all, Edison sold bamboo charcoal filament lamps for 30 years, we can sell it for three years! Regardless of whether it is a consumable or not, it is better than having to add fuel in a day or two. Today's meeting, if nothing else, is to focus on this bamboo charcoal wire lamp, to develop a set of technical solutions and promotion programs. ”

In fact, when it comes to specific solutions, there is not much difficulty in technology, the steam turbine is already running, and there is not much difficulty in power transmission and transformation, and drawing copper wire is a piece of cake, as for the insulation of copper wire, it has basically passed the test some time ago, and the insulation layer of copper wire outsourcing is currently the method of repeatedly brushing paint, well, it is not much different from painting, although there are flaws in safety performance, but so-so can be regarded as passing.

Regarding promotion, there is no pressure for the time being, because electricity is not yet extravagant to the point of being used up, many projects are queuing up for electrolysis, and electricity is not surplus but insufficient. Therefore, the first phase of the electric light project is only limited to the public sector and some high-end people.

However, in this imperial society, if there are good things, at least let the Great Song Emperor share them, no matter which aspect of political correctness and experience interests, this must be considered.

As a result, it was decided to build a special electric lighting system for the Great Song Palace, and no one objected to this, all the travelers were from the 21st century, which was worth it anyway from an advertising point of view.

As soon as the meeting ended, Mao Geng rubbed his temples and wanted to relax for a while, but when Mao Geng stepped into his special office, he immediately heard Wang Qinqin's voice:

"The meeting is finally over! Maut, we've been waiting for you here for a long time. ”

Seeing that it was this headache-inducing Wang Qinqin, Mao Geng was a little big, but when he saw Wang Qinyin's appearance of wanting to speak and stopping, Mao Geng smiled and asked:

"What's the matter?"

"Qin Yin and I want to study chemistry, how about you tell that Mr. Gu and let us enter the chemistry group?"

Mao Geng suddenly couldn't cry or laugh, did he enter the Gewu Academy casually! Besides, when girls learn chemistry, Wang Qinqin is just going back, and letting Wang Qinyin mess with those acids and alkalis feels very discordant. The point is that the chemistry team is going to try to make all kinds of explosives/explosives, which is really a high-risk business, and it is better for women not to touch it. As for Gu Yongqiang, he doesn't care about chemical pollution at all, that's still a trivial matter.

Seeing such a fair beauty as Wang Qinyin, Mao Geng shook his head and said in his heart, why do you want to coax with Wang Qinyin!

"It's not easy to study chemistry. What's more, Master Zhu Xi is now the dean of the Gewu Academy, do you think Dean Zhu will accept women into the Gewu Academy! Mao Geng imagined Zhu Xi's discriminatory attitude towards women, and thought to himself, even if I agreed, Zhu Xi would definitely not agree. If you want to enter the temple, there is no door!

Wang Qinyin couldn't help but say at this time:

"However, Tan Wangdi is also a woman, isn't she also fiddling with chemistry! If she can do it, why can't we! ”

Speaking of which, Wang Qinyin's words were quite coquettish, which is a bit rare.

Because of the burning of glass, Tan Wangdi did come into contact with soda ash early and entered the door of chemistry, but Tan Wangdi was only a disciple of Mao Geng, and he did not match the Gewu Academy led by Zhu Xi.

Mao Geng then explained:

"Tan Wangdi learned some chemistry from me, and she is not in the chemistry group of the Gewu Academy."

Of course, Mao Geng will not hand over all the qiē techniques to Zhu Xi, that is actually a gesture, the short and fast is still in the hands of Mao Geng, and generally only long-term projects will be handed over to the Gewu Academy, which is also done in later generations.

Seeing that the two of them were still unhappy, Mao Geng continued to persuade:

"That's it, why don't you learn about textiles, ready-to-wear or cosmetics, I can say hello to them, Mr. Qian, you can learn from them, how about it?"

"No, I have to study chemistry." Wang Qinyin recognized it this time, looking pious.

Mao Geng remembered that in the past few days, people have interceded with him one after another, and they all want to insert people into the chemistry group, which is ridiculous. Even Yan Rui recommended a distant relative to enter the chemistry group yesterday. Mao Geng smiled bitterly, unexpectedly, overnight, chemistry became a popular major.

"Let me think about it, I'm afraid it's not possible to go into the chemistry group, in fact, you don't have to go to the chemistry group to study chemistry, I think about it, or, there is another way."
