Chapter 569: Scientific Achievement Conference

Fan Zeng's report was quickly handed over to King Qin. This report pointed out in detail the needs of the national security strategy. And specifically pointed out. The specific role of military commanders in the national security strategy and the reality that it is not in tune with the national strategy. The emergence of this position combines the effective and specific roles of generals to jointly fulfill major strategic needs.

King Qin also understood that the State of Qin was a little blind in foreign wars. Especially the practice of fighting any enemy is a bit too much. He vaguely felt that it should be controlled. Now there is such a position. King Qin accepted it very much. So King Qin accepted this request.

The emergence of the national security adviser indicates that Qin will set up a special foreign post to manage foreign operations and handle foreign relations. The external and peripheral security strategy was formally incorporated into the Qin State's operating mechanism.

Although the State of Qin established such a special post. But still need a lot of technical support.

The holding of Qin Geography Conference will bring no small contribution to Qin. Since Qin State holds various sports events. The academia, unwilling to be lonely, also began to set up a spontaneous organization to hold various conferences and exchanges. The Geographic Conference was established in this context.

With the emergence of various measurement tools such as the Qin State Astronomical Telescope and Sextant. Qin has made great achievements in geography.

When the astronomical telescope was observing the trajectory of the moon, the researchers confirmed the view that the celestial body is spherical. At the same time, Qin Guo discovered the fact that the earth is also spherical when measuring the meridian. Subsequently, the trajectory of the sphere became a new research object. In this process. People have discovered the fact that the sun is in the center. Although somewhat prejudiced. But it greatly pushes astronomy to a new theory of knowledge. Then people will evolve the relationship between the earth, the sun and the moon based on these theories.

After proving that the earth is spherical. The Geography Congress successfully measured the length of the meridian. The data still cannot be compared with the present. Because there is a big conversion relationship between the two. Shang Wen could not find the connection between the two. But a new unit appeared. It's called Miaozhang.

Miaozhang is actually a later section. The unit of a section is actually the unit of latitude one second. The Qin Geographic Conference successfully calculated the unit distance between one degree, one minute, and one second in latitude. Among them, the stipulated one second is eight hundred feet. Approximately 1.85 kilometers of one nautical mile in modern times. Shangwen believes that there must be an error in the middle. In fact, such an error does exist. But this is indeed a major improvement.

The Geographic Conference made the first theodolite, and began to divide geographic latitude and longitude on the existing map of the Qin Kingdom. For this reason, they specially made a globe and gave it to King Qin. Although only known geographic information is marked on it. But this is already a big development beyond history.

Then the geographical time was calculated based on the division of latitude and longitude. Every fifteen degrees is a local time slot. The Qin State is divided by the meridian where Xianyang is located as the starting meridian. East is east longitude. To the west is the west longitude. When fifteen degrees is one place. That is, the local time difference of one hour. Because the warp distance cannot be measured. There is no fixed number. So just use time instead.

The conference also declared that the Qin State Xianyang time shall be the unified time of the Qin State. The appearance of the telegraph has allowed people to discover the huge difference in geography at the same time. Qin State was still when the sun rose in the morning. The west is still dark. This made King Qin feel the huge geographical difference for the first time. King Qin agreed to this. For this reason, the Geographic Conference also stipulated the time method of east plus west minus.

Great geographical discoveries require close calculations. Especially mathematics and geometric support. Triangulation has become very common. Even Qin’s children know how to use their arms to estimate distances.

The Mathematics Conference was also held in Xianyang. But not many people participated. It is mainly caused by the dullness of mathematics. The entry of ordinary people is mostly related to survey work. They just want to learn some new mathematical knowledge.

The Pythagorean theorem was recognized at the mathematics conference and began to enter the textbook of basic education. With the application of triangulation. Qin Guo will continue to study. And start to extend to the trigonometric function. this period. Qin's mathematics knowledge began to mature in one yuan, one time, two yuan, one time mathematics knowledge. Mainly artillery, and a large number of mathematical problems accumulated in life knowledge.

Industrial production. Especially the need for roundness in bearing design. Bearings are not bearings in the current sense. Instead, the bearing is fixed by adding lubricating oil to the bearing. Synthetic liquid ammonia has not yet appeared. There is also a lack of refrigeration equipment for industrial use.

The mathematics conference put forward the concept of pi for the first time. At the same time in the process of making a circle. Someone proposed the method of infinite cutting and rounding. This is the earliest embryonic form of calculus. Next, Qin's mathematicians will focus on this topic. Another result is that graphs solve mathematical problems. The parabola comes from artillery. The four-limit graph comes from stock analysis, and there is also probability. This is also brought about by speculation. Mathematics comes from life.

Great achievements have been made in chemistry. But the differences are extremely serious. Chemistry began to separate. Because some chemists insist that they are genuine chemistry. This divergence stems from the differentiation of organic chemistry and inorganic chemistry. But Qin State has not yet made such a division. Instead, some chemists are pushed into the field of agricultural research.

These chemists mainly study phytochemistry. Then started the research on oil and coal. They think this belongs to the biological field. The substances they burn and decompose into carbon dioxide are turned into biochemistry. This is naturally opposed by chemists who study metal and non-metal conductive materials. So the two differ greatly. These gentle and weak scientists almost started fighting. But this issue was shelved. Even experienced chemists cannot explain these problems. They need research to give answers.

But the chemistry is very successful. The first is that the discovery of various metals has allowed Qin State to make rapid progress in metals. For this reason, the first periodic table of chemical elements appeared. But only metals, the main reason people are based on the replacement reaction. Although there are limitations. But I can realize that this aspect is very good.

There is also micro-chemistry, and quantitative chemistry is beginning to be determined. And become the most important chemical method. However, there are also places where it is impossible to restrict chemistry. Such as chlorine. People are doing by-products of electrolysis experiments. But it was quickly applied to tap water. The people of Qin have abandoned the well water to drink this disinfected water. Scientists demonstrated an experiment in which chlorine gas was used to kill a dog. It is believed that this can also kill harmful bacteria in the water. Biology always sums up a lot of scary things for people to accept.

But the problem came out. This toxic gas can kill animals as well as humans. Can it be used as a weapon? The answer is yes. But the chemistry conference is an academic exchange. Killing is a matter of weapons. Can poison gas be used to kill people? Chemists think this is not their business. So this matter was shelved and handed over to other areas. Only the government does not know about this. Because they are busy developing southern things.
