The two invisible meridians are the dividing lines between two dynamic social organizations that have capital to do things overseas.

Behind these two lines is a large capital group that has taken shape and least wants to be divided or become independent along the coast. At this time, the republic was the best host of capital, and the interests of industrial capital and commercial capital were identical, and they were being forced to expand externally by profit-seeking.

Splitting and becoming independent are the last things they want to see for capital groups like Nanyang Company, and they don't want to see them for factory owners and big workshop owners. Anyway, there are middle and bottom levels of tax equilibrium and so on, and they don't need to take on more obligations, but they need a large and unified domestic market. On the contrary, there is a bit of a spread of middle-level liberal ideas such as small citizens, and a small number of people feel that they can live a good life by going out independently, but the pursuit of big capital for markets, raw materials and cheap labor, as well as cheap cannon fodder that is easier to publicize, will crush this careful thinking.

The colonies also required a large amount of military investment to secure profits, and there were tariffs and threats of force in the external market, where could there be reasonable and legal territorial dumping at home.

A lot of things that Jian Chen has to do in China is to help this group of people wipe their butts. Find a vent point for the grievances of the petty bourgeoisie and small peasants as much as possible, whether it is emigrating, advocating political change, or striving for the dominance of public opinion and propaganda, a large part of them are buying time for capital, otherwise it is very likely that the ruling families of the old era will take advantage of the dissatisfaction of these people to form a strange new chaebol group and fanatical bottom that rapidly turns to the right, which will need to hold on for a while to let the tumor of the old era of capital penetrate deep into every flesh and blood of the country and cannot be removed.

The Nanyang group of people caught up with a good era, and took advantage of the contradictions in Europe to win three legitimate trading ships to the Spanish colonies, relying only on the deterrence of their huge size and the ability to be enough to be-stirring sticks, without spending a penny or a single soldier.

The Dutch shed their blood for fifty years, but in exchange for a truce that could not be traded in the Spanish colonies and the homeland, instead of an armistice and formal independence. The British sweated in fear before the Invincible Armada, in exchange for the complete abandonment of the Dutch on the issue of Asian spices, after finding a new ally. Spain was forced to bankruptcy by the Dutch and had no choice but to make peace, in exchange for Chen Jian seizing the opportunity to intervene and intervene in the name of non-interference, no loans, no alliance with the Netherlands, and three legal trading ships in exchange for the joint fight against piracy.

The perfect starting line has been drawn for Nanyang Company, and the rest of the work will depend on the capital group itself.

Withdrawing from the shares means completely disconnecting from this group of people, from the original alliance of interests to a short-term political alliance that is independent of each other.

In contrast to this commercial capital, which has been freed, Chen Jian understands that the next ten years will be spent on industry, technology and development education.

After the matter of the withdrawal of shares was dealt with, Chen Jian was ready to take a look at the Institute of Science and Practical Technology and the Lanxiang Technical School, which had been investing a part of their annual income since six or seven years ago, before going to the capital.

Normally, this was an era when craftsmen were above theoretical scientists, but this situation was forcibly reversed by Chen Jian, and a large number of young people with elementary level theoretical knowledge were trained on the basis of systematic simple mechanics and chemistry after seven years.

Mincheng and Nan'an had many craftsmen with a high level of technology, with excessive salaries and high prices of patent monopoly jointly endorsed by Chen Jian's capital, party organizations and capital groups, and formed R&D groups with young people who had passed through the primary level of theoretical knowledge.

Normal technological progress is that capital is in demand, an invention is profitable, a craftsman tries it, invents it, improves it, and uses capital.

This is a long cycle and a normal development pattern that is not foreseeable.

But the Institute of Practical Technology in Minjun is completely different. Chen Jian contributed money, put forward a "vision" or the direction of improvement, prepared in advance by estimating the demand for capital, invested a lot of money to complete the research and development by craftsmen, and threw money at people in a definite direction.

This is a method that cannot be replicated elsewhere, and it is also a method that cannot be replicated by others, but this kind of "planned" research direction is the best choice for Chen Jian, which is far better than disorderly "free" development.

Since he got the first pot of gold, he has been investing a lot in this area, mainly five things.

Precision balances, realizations of glass models of steam engines that have been exhibited at the Academy, marine clocks, new pump-type non-bellows blowers, controllable foot-operated or hydraulic boring machines.

These five extremely expensive and costly things, the annual financial guarantee is sufficient, and there are constantly foreign enemy craftsmen who have passed the craftsman certification to join in the research and development of these five things.

In addition to these, there are a lot of various projects, and the most important advice he has before going to sea is not to cut off the money in this area, and to continue to invest in all kinds of improvements.

He doesn't know exactly how these projects are going, but he believes they won't be too slow. The relationship between craftsmen and science needs to be generalized, and someone needs to use science to turn into technology, and the primary mechanics of the system make all this combination faster.

Before going there, Chen Jian first flipped through the scientific articles published in the past few years when he went to sea, and these things were collected and sorted out by special people, so it can be said that no wind and grass have been left behind.

In the past few years that he has been going to sea, there have been a lot of things in the academic world, and one controversy after another is inevitable, and the acceleration of research caused by things based on those basic theories can also be significantly felt low.

After roughly flipping through the books and pamphlets, Jian Chen was convinced that two major events had occurred in the scientific community.

Before going to sea, Chen Jian did an experiment on the slope of a small ball in the Xuegong, talked about the philosophical concept of defining mass for seven or eight days, calculated the centripetal force of circular motion, and gave the conjecture of the theorem of gravitation.

By now, all these things that are defined by the foundation have begun to take effect, and they are constantly being refined within these basic definitions.

But a lot of things Chen Jian just made a start, dug a big hole and fell into a lot of people, patted his ass and went out to sea. But those who fall into the pit do not feel bitter, but on the contrary, they fight for the irritability problems in the pit.

The measurement of gravitational acceleration is a large pit dug by Chen Jian, and people are roughly divided into two factions around this large pit.

One school can be called the inclined plane surveying school, and the other school is called the basic anti-thrust school.

The inclined plane surveyors continued Chen Jian's original experiments, and continued to make smoother inclined planes, smoother balls, more perfect spheres, more accurate timing devices, and more repeatable experiments.

They were convinced that as long as the bevel was smooth enough, as long as the sphere was perfect enough, and as long as the timing mechanism was accurate enough, the gravitational acceleration would be more accurate after repeated experiments using trigonometric functions.

On the other hand, people believe that the bevel cannot be smooth in any case, and that it is impossible to make a perfect sphere now, so the error of this measurement method is too great, and it is completely possible to use other methods.

For example, the pendulum has already been discovered by the eyes of the isometric isochronism, just like discovering that objects are falling faster and faster from the sky, relying on the summary of the eyes, and giving such a theorem, but no one knows why it waits.

However, with the introduction of mechanical concepts, acceleration, centripetal force and other issues, the pendulum has become a sharp weapon for the basic anti-thrust faction.

According to the relationship between force and acceleration and centripetal force, using the same primitive calculus method as Chen Jian calculated centripetal force in Xuegong, the relationship between the periodic formula of the pendulum and gravity was deduced—they were convinced that the resistance of air was smaller than that of an inclined plane, so that the measurement results were more accurate.

What the fundamental anti-pushers need is a theoretical foundation, but it has to be said that they made the right choice, because all the theoretical foundations needed have already appeared. The calculation of pi had long been completed, the triangular heat and cold tables in tens of points had long since appeared, and the earliest returnees from Europe had brought back the most basic things that had been corrected by the comparative version and the mechanical acceleration, which had been reduced to formulas.

After using basic mechanics to deduce the periodic formula of the pendulum, it is only necessary to determine the length of the pendulum, use the existing timer to calculate the swing time of the pendulum, and then apply it to the formula to calculate the magnitude of gravity.

The internal logic is impeccable, the external operation is certainly less frictional than the inclined plane, and in order to be as precise as possible, the hermetically sealed glass cover can be filled with carbon dioxide and absorbed by caustic soda to theoretically eliminate the resistance of the air as much as possible – the latter is undoubtedly more precise at the same level as the chronograph mechanism.

In the early stage, the inclined plane surveyor school firmly held the advantage.

However, when the single-pendulum formula was reversed by the other school, the whole form was greatly reversed, and a formula and experiment that skillfully used mathematics, chemistry and basic mechanics defeated the traditional single-subject experiment, and proved that internal logic can defeat experience through deduction.

Chen Jian converted the results they got according to the formula he was familiar with, and he had to admit that this result was very close to the correct answer, about 9.6, and it can be said that this number can be completely applied.

This classic story does not end here, and the winning faction, in order to repay the theory proposed by Chen Jian, conducted another sensational experiment according to logical deduction reasoning.

They propose that since the Earth is rotated, the Earth's equator should be longer than the two meridians. Similarly, according to the connection between gravitational forces, it is inversely proportional to the square of the radius. At the same time, because of the centrifugal force brought about by the rotation of the earth, the gravitational force will be smaller.

So according to this inference, the same pendulum length, if measured in the mountainous areas of the south, will be slower. And in the valley hollows of the north, the swing will be fast.

This was a major event that helped Jian Chen's theory to be validated, and even though Jian Chen was at sea at the time, these people still had enough financial support to complete the experiment.
