From Chief to Ball

Lan Qi was not eager, and also drove away the trace of regret.

"In the future, maybe we will become very good friends. Have a lot of time to listen to him talk about these things."

Since you will become friends, why bother to watch these dazzling things at once?Anyway, that dazzling person is there, we will meet in the end, and he is not from two worlds, it is more interesting to listen slowly than to watch.

Facing the crowd that was still coming this way, he walked out in the opposite direction, until he turned back at the street corner and glanced at the already blurred people.Lan Qi smiled and thought: "This winter, many people will burn the lotus root-like coal, and the money saved may be enough to buy a firecracker for my son and a few new red-headed ropes for my daughter."

Chapter 98 Little Storm

In the name of doing good deeds, turning the money he can't earn into fame is something Chen Jian is very good at.So briquettes can be publicized to make more people live better, but if someone wants to make glass, crucible steel and other technologies, that is another story.

Not long after the fair ended, several gentlemen from Xuegong approached Chen Jian again and asked about the spectroscopic prism. Chen Jian only said that he didn’t understand, and sent several sets to Xuegong for them to play by themselves.

There is no need to perfect everything after starting something.Chen Jian knows his own position, that is, a medicine introduction. If there is no overall level of this ethnic group as the main medicine, his medicine introduction is useless even if it is a elixir.

Nowadays, things like mirrors, lead glass, and spectroscopic mirrors have been brought out, and the previous theory of particles of all things is used as the philosophical basis. It is not far from the theory of particles of light, and someone will always come up with it.

Especially for the reflection angle of light reflection, the theory of microparticles is the most acceptable theory, which invisibly cheers for the theory of microparticles.If it is proposed by oneself, it will inevitably lack sufficient convincing power.

The foundations of mechanics, chemistry, optics, electromagnetism, biology, and rational philosophy can be regarded as basically laying out a fertilized egg.

Although this fertilized egg is at best a tadpole just swimming in, it still needs enough time to grow.

Now there is no need to come up with too many theories, but to come up with some wonderful things that really change the world based on reality, to prove that the research on these things is meaningful.

Not long after that, Chen Jian also met a person whom he had always wanted to meet but had no luck with. He was the gentleman who speculated that the orbit of the star Yinghuo was elliptical in the brochure he read when he came to this world for the first time.This gentleman has a good foundation in mathematics. He didn't see Chen Jian a few days ago because of his eye disease, but this time it was because of the telescope.

For a person who observes astronomical star maps with the naked eye, the telescope has infinite charm.It's just that the magnification of the telescope in Chen Jian's hand is too low, and it's the only one. It's impossible to see the vastness of the universe and the vastness of the starry sky when you use it to look at the stars.

This gentleman is also in charge of astronomy and calendar reform. He is a figure in the system and has a high reputation.The new calendar that is commonly used today was revised by this gentleman. He has spent his whole life on stars and mathematics, and used triangulation to correct the relative distance between the planets and the sun on the basis of the predecessors: How far is the distance? It is far from knowing, but the ratio can be inferred. This is the highest level of astronomy in the era without telescopes.

Chen Jian was not in a hurry to discuss with this gentleman the mysterious connection between the planetary travel time and radius, but thought of some things that would be used for navigation in the future, so he used a telescope with a higher magnification to lure him.

After watching the stars all my life, what I want to know most is what the stars or the moon look like, especially when I saw the faint craters on the moon with the broken low-magnification telescope at night, I was even more excited.

Chen Jian said that it is not easy to make a telescope with a larger magnification. It is necessary to ask for a sum of money in the name of the husband in charge of astronomy, and find several mirror grinders in the capital who are willing to do this kind of thing.

The money was not much, and the husband could make his own decisions. After agreeing to Chen Jian, Chen Jian made further progress.

He proposed that he would donate a sum of money to build a special observatory, place telescopes and other clocks, watches, celestial globes and other things.However, considering that there is too much soot near the capital, and the telescope used to observe the stars is too large and inconvenient, it is hoped that the observatory will be located in Mincheng.

To build an observatory, the building alone does not cost a lot of money, three to five thousand silver coins are enough.But those who look at the stars and calculate the calendar in the observatory are priceless, and Chen Jian can hardly match them.

What he said was a big deal, and my husband finally agreed. By the way, I will take some disciples to Fujian City to personally supervise the construction of the observatory. I also hope that I can see the telescope that can see the stars for the first time.

Chen Jian naturally had his own considerations. There must be an observatory in the age of sailing.Whether it is orientation, timing or others, there must be an observatory as a support.

Once Mincheng becomes the HNA center in the future, the existence of an observatory will make this center more valuable.

Now a simple sextant...or an octant has been made, even if there is no such thing as a starboard, the measurement of latitude is absolutely no problem, as long as it is still in the northern hemisphere.

However, the measurement of longitude is extremely troublesome. You only know the latitude but not the longitude, and you will never know your exact location.

There are only two ways to determine longitude.

Or it is stipulated that the location of a certain observatory is zero longitude, which is divided into east and west. There is a clock on board that ensures the same moment as the location of the observatory and the time is extremely accurate.The exact longitude can be deduced by relying on the time of the observatory and the time of the location. Theoretically, the clock is accurate enough that the difference can be several kilometers.

Or rely on astronomy, rely on methods such as drawing moon phase maps, and publish an issue every year.Assuming that the orbit of the moon in the sky is fixed, and the changes of the positions of the stars in the sky are also fixed, then as long as you can draw a perfect enough star map and deduce the orbit of the moon, you can take a nautical moon phase book in your hand. Figure, look up at the sky to infer the time of the observatory at this moment, to infer the longitude.

For now, neither approach is in sight.

The clocks and watches required by the former are too creative, taking into account issues such as turbulent waves, thermal expansion and cold contraction. As far as the current level of clocks and watches is concerned, a difference of 5 minutes a day is a master level. Four minutes to one longitude, the north and south poles are okay, but the latitude of Mincheng is different by dozens of kilometers a day.

The latter requires a team to stare at the stars every day to draw a ten-year star map, and then perfect the law of universal gravitation and estimate the distance of the moon. By the way, it also needs a blind person who can still calculate the calculus mentally to write the moon's movement into a formula.

This is definitely not something that can be done in one generation, it may take several generations, but it can be prepared in advance, at least complete the star map first.This investment in basic science stems from the need for great voyages, but Chen Jian knew what he was going to do, so he could make preparations for this seemingly meaningless and huge investment in advance.

Without an observatory, the best navigation of our time would not be possible.Without astronomy, the most accurate maps of our time could not be drawn.Those who do not look at the stars may even have problems guiding the farming season.

Although Zheng He, Columbus and others did not have these conditions, they still conquered the sea, but at one time and another.Chen Jian did not sail around the world, but turned this craze into huge benefits immediately after sailing around the world, reducing the risk of going to sea and ensuring sufficient profits.

In addition to its own practicability, an observatory has many other uses. For example, after the appearance of telescopes, Jupiter’s satellites were discovered, and then a very important problem was suspected from the time difference of the wooden eclipse caused by the satellites: the speed of light is limited rather than unlimited.

These things can't be done by talking nonsense, and professionals must study and point out.

Using a cement and masonry observatory and a telescope to lure a group of top calendar astronomers to help draw star maps and measure time is profitable no matter how you look at it.

The old and the young chatted for a long time, and finally settled down.In a few days, you can go to Mincheng to complete the foundation laying of the observatory, and strive to get a telescope with a larger multiple within five years.

The old man promised that as long as Chen Jian got out the telescope and built the observatory, Chen Jian would be given an official status equivalent to that of the head of the Qin Tianjian, which is quite a prestigious quasi-technocratic status.

After sending the old gentleman away, people from the military came again and asked Chen Jian about the telescope.Chen Jian only said that his father came up with this thing, and it had been sent to the navy through normal channels.

As a result, some telescopes were added to the military's procurement list, and telescopes were added to the prohibited trade list, which was a surprise.

In addition to these important people, there are actually many people who come to Chen Jian, especially those strange and weird goods that are not sold, and they all want to cooperate with Chen Jian.

However, Chen Jian also knew that there were only a few items that could be sold at a large-scale profit at this exhibition, and many items were made at a high price.

For example, lighters are not practical.There are Shizhi pharmacies and pharmacies, but they are all collected naturally from some oil seedlings, and they are also used to treat skin diseases.Using a glass still can make a small amount of gasoline to make a very dangerous lighter, but it is still too early to be practical.

Gasoline is easy to fry.But the current flint of kerosene is really impossible to ignite. There is no flint of magnesium alloy or rare earth alloy. With the current flint, the hammer device on the flintlock has to be installed to ignite kerosene.Then it's not a lighter, but a musket, which ordinary people can't afford, and it's not compelling.

The role of appearances is to make people not aware of the seriousness, and by the way, people think that the knowledge learned in the academy can produce so many good things, enlighten the wisdom of the people, and make people no longer awe of nature, but on the contrary, they are in awe and even proud of their own. mighty.

I sent away wave after wave of people with different goals, and secretly asked those who had the opportunity to cooperate formally, and left invitations for these people. We will discuss making money together in a few days, and the rest of them are After entertaining, I shirked it.

This time I came to the capital, and spent a total of more than 3000 silver coins on various goods, experimental equipment, purchased venues, and hired labor.

He has gained a lot of fame and admiration, but he hasn’t seen a cent of the money so far. Chen Jian is now considered one of the top capitalists in Nan’an County, not counting those mining mines. The [-]-ton sailboat and the two artillery guards of the merchant ship disappeared like this.

It was neither the party's property nor the company's funds, but Chen Jian's own money.

Hu Lin didn't know how much it cost, so he was very excited when he saw people coming and going every day, thinking that the business company had finally spread out, and the banquet for those merchants in the capital seemed to Hu Lin to be the last step for the business company to gain a foothold here. .

Chapter 99 Realization

It has to be said that the charity business association in Mincheng caused a big disturbance in the capital, making this dull summer even more memorable.

In addition, Nan'an County, a small county that many people do not know in the capital, is also a household name in the capital.From glass to hot air balloons to weird trade fairs, the name of Nan'an County is everywhere, and many people go back and look through books to find Nan'an.

It seems that there are only a few words: it belongs to Fujian County, in the Yang of Minshui, its mountains are rich in coal and iron.

Before that, Nan'an in Fujian County was really one of the 36 counties in the country. The iron mines near the old capital Yucheng are comparable.

After that, no matter whether it was an official, a wealthy businessman, a large landowner who hired labor, or a trafficker, everyone knew about Nan'an County, and it was not much worse than those well-known counties.

Some people pay attention, and naturally some official news about Nan'an will inadvertently attract some people's attention.Someone finally saw an evaluation of Nan'an County last year, saying that in Nan'an County, the old, the old, and the old are well-supported;
