For Shi Zhan, after having the concept of longitude and latitude at what time and what star position, it was enough to determine the latitude and longitude point, and then use a formula to calculate the distance of another longitude and latitude point. The whole process was simplified to a ridiculous degree.
"Hmm, that's it. My method is good, isn't it?" Wan Zhen asked excitedly.
"It's more than good." Shi Zhan said with some emotion, "Our Gan and Shi families have never thought of doing this for thousands of years. Chang'an has already made such a layout, but we have never thought of considering it.
Release it to the world."
This may sound a bit outrageous, but in fact it is true, because from the time Chang'an City was first established in the Han Dynasty to the 21st century, the internal roads were basically straight south, straight north, straight east and straight west.
kind of distribution.
Therefore, the location of Chang'an City can be determined by using East-West Street and North-South Street. Of course, the unlucky child who should have gotten lost will still get lost in this situation...
It was precisely because of this understanding that Shi Zhan was able to quickly react to what Wan Zhen was talking about. However, compared to the actual layout of Chang'an, the longitude and latitude on this spherical surface relied more on the imagination of people like them.
, but with Chang'an as a reference, there is no problem with this method.
"I don't understand what you are talking about at all." Li Jue said in a very calm tone. Wan Zhen smiled when he heard this. It was normal for him not to understand. Wan Zhen had no hope that Li Jue and the other three could learn it.
This kind of thing, even if he thinks these things are very simple.
"I also thought of this accidentally. You two calculated that the earth is a ball, and the concept of the earth having poles was proposed by the Wang family of Kuaiji. So the maximum circumference from the pole of the ball to the throne of Weiyang Palace
It's the meridian." Wan Zhen said to Shi Zhan with a smile, and Shi Zhan was already extremely impressed by Wan Zhen at this time.
These things are not magical after all. The concept of the earth having poles was first proposed by Wang of Kuaiji. Although there has been a lot of confusion, up to now everyone who studies astronomy and mathematics basically agrees with this concept, although theoretically the ball has no poles.
Yes, but the Wang family of Kuaiji proved the existence of magnetic poles, so the giants are willing to give face and admit that the earth has poles.
After all, having such a pole is really useful at certain times.
Just like now, the curve running through the throne of Weiyang Palace on the spherical surface with the south and south poles is regarded as 0°, and the opposite side is regarded as 180°. Shi Zhan can take the next steps in his mind without thinking at all, because a day is close to twenty-four hours, so the longitude
Divided according to 15°, time zones can be made directly according to the rotation of the earth.
This is not the most important thing. The most important thing is that they have already calculated the maximum circumference of the earth, so they can directly determine the distance from each time zone to the next time zone.
"Next, as long as we make the latitude line, we can calculate the distance between the two time zones on this latitude line according to the angle. In this way, if there is one clock as the time in Chang'an and another using a sundial, we can determine the time by comparing it.
Our vertical position on the earth." Shi Zhan had already caught up with Wan Zhen's thinking at this time and was extremely emotional.
"The date and the angle of the sun at noon can roughly calculate the horizontal position of the person, so that the longitude and latitude can be roughly determined. It can be said that as long as there is time to compare, it is almost the same." Wan Zhen told Shi Zhan what he had not yet responded to.
After adding, Shi Zhan fell into silence.
This knowledge is difficult for ordinary people in this era, but it is not too difficult for elites from the Gan and Shi families like Shi Zhan.
To be precise, these knowledge families have detailed teachings, but after thousands of years of inheritance, no one in the two families has summarized and synthesized this knowledge.
On the contrary, Wan Zhen put these things together into a whole when he came into contact with them for the first time.
From a certain point of view, Wan Zhen may not be able to do research, but Wan Zhen is definitely a master of data assembly. Just like now, Wan Zhen has easily completed something that took others thousands of years to come up with, and he still finds it very easy.
Although the knowledge reserve of these things has been completed as early as the second century, it took thousands of years to synthesize this knowledge to produce operable and reusable technologies.
But it's easy to put this kind of thing into perspective. Just like now, Shi Zhan just thinks that Wan Zhen is indeed gifted, and doesn't think that this guy has transcended a thousand years.
Because Wan Zhen and Lu Jun are very different. Although both of them have transcended a thousand years, Lu Jun's transcendence relies on the knowledge developed and researched by himself, accumulated bit by bit, so it seems very shocking.
Wan Zhen's journey beyond a thousand years is different, because all of this guy's technology and knowledge have been summarized by his predecessors, but no one has integrated and interspersed these fragmented knowledge in a systematic way before, but this is not
It means that this knowledge does not exist.
In fact, the Gan family and the Shi family, who had calculated the circumference of the earth, the ecliptic plane, and the more accurate values of gravity acceleration after Chen Xi reminded them, their family knew every piece of data used by Wan Zhen.
Yes, so when they face Wan Zhen's achievements, they will only sigh and not feel how shocked they are.
After all, for the Gan family and Shi family who already had a foundation, the reason they didn't succeed was just because they didn't pay attention to this aspect, not because they didn't understand it.
But in fact, sometimes it is very scary to put together professional masters, and it is obvious that Wan Zhen is a typical technical master in history. Even among the more than 200 million people in the four major empires in the third century, Wan Zhen was ranked second.
No one dares to claim first place.
After all, it is impossible for a normal person to collect information and write a very accurate work such as Nanzhou Foreign Object Chronicles without conducting on-the-spot investigations. It is also possible to extract the knowledge you need from other people's knowledge and piece it together to create a new look.
An extremely high-end wisdom.
Of course, currently Wan Zhen doesn't think he is a god. At most, Shi Zhan is only impressed by Wan Zhen's ability to integrate knowledge, and is not as shocked as seeing a god.
"In the end, I still didn't understand it at all." Fan Chong said with a sigh on his face.
"If you want to understand this kind of thing, you still need to learn more mathematics. It is best to have a relatively advanced understanding of arcs." Shi Zhan said sincerely.
The three of them, Li Jue, scoffed at the words. Study, what the heck, math is something that the three of them should learn. They just need to be able to add and subtract, and not be fooled by others.
"Although it sounds interesting, it can be used to identify our location on this planet, determine our distance from Weiyang Palace in Chang'an, etc., but I don't think I can learn it at all." Wu Xi said with a sigh.
.
Speaking of which, Wu Xi studies hard and constantly strengthens himself, but it is obvious that the high-end knowledge that Wan Zhen talked about before is more difficult to learn, and he cannot learn it.
"Actually, you don't need to learn these things. With me following you, it doesn't matter whether you know it or not. I just know it." Wan Zhen said casually. He is now considered a member of the Xiliang Iron Cavalry. Although his combat effectiveness is relatively weak,
But he is also very resistant to beatings.
"Look, there is always a way to solve the problem. Just like here, there is no need to learn at all. We also have the correct way of positioning." Li Jue said very calmly, and then looked around secretly as if he remembered something.
After checking to make sure Zhou Yu was not there, he coughed twice.
"If you have anything you want to say, just say it, brothers, I won't look down on you." Guo Si instantly understood Li Jue's intention and said casually.
"I'm thinking about a new problem." Li Jue asked someone to block the spread of his voice, for fear of being discovered by Zhou Yu, and then he spoke cautiously.
"What problem deserves you to be so cautious, and what is there for you to consider? If it doesn't work, just jump to the Great God. Jumping to the Great God can basically solve all problems." Fan Chou said with a tone that he didn't know whether it was ridicule or perfunctory.
said.
Li Jue didn't have any special feelings when he heard this. He had been hanging out with these two guys for so many years and had long been accustomed to this way of communication and didn't care at all.
"Do you think the ship we are traveling on is considered a mount?" Li Jue suddenly made an astonishing statement.
I have to say here that the breadth of thinking of people who often dance with great gods is difficult to be surpassed by others. Just like now, when these words came out, even Guo Si and Fan Chou were shocked. As for Wu Xi, Wan Zhen
, Scumbags like Wang Fang were even more shocked and didn’t know how to answer.
How could something like a boat be considered a mount? This was what the ordinary Xiliang Iron Knight soldier who could barely be considered normal thought and asked the same question.
"A boat is not a mount anyway." After Wu Xi thought about it again and again, he finally came to his conclusion. Although the riding range of the Xiliang Cavalry is very wide, it is really outrageous that a boat can be considered a mount.
.
"No, no, no, why can't a boat be considered a mount? This thing completely conforms to all the attributes of a mount, but anything that can be ridden is a mount, and boats can also be ridden." Wan Zhen is just watching the excitement and is not afraid of big troubles, plus
Li Jue's question stimulated Wan Zhen's spirit, and his aura began to explode wildly. He had already thought of many possibilities and operations.
"Theoretically speaking, we can use the First Auxiliary Legion riding the Rhino as mounts, then it is also possible to use other gadgets as mounts." From the perspective of reasonableness, Guo Si felt that this was still possible.
"The question is, even if the ship is a mount, how much talent do we need to cover such a large mount?" Fan Chong asked. As soon as he said this, Li Jue scratched his head.
"In fact, when we used the first assistant as a mount before, you should also have discovered that our talents cannot cover the first assistant and the rhino at all." Fan Chou explained seriously, "We are very strong, but
We also have limits."
The Xiliang cavalry are considered top cavalry. The most important thing is that they indeed share their talents with their mounts.
War horses share the rider's talent, which is the foundation of the cavalry's strength. In turn, maintaining this strength forces cavalry with the same level of talent to have a much higher real talent intensity than ordinary infantry. After all, the cavalry's talent needs to be shared with their mounts.
This is also why the unlucky boy Taqituo fell down to the third level of talent three times. On the one hand, the horse he changed was so good. When the Xiliang Iron Cavalry originally changed to a Sharma horse, they could only give him a Sharma horse at the beginning.
It provides part of the spiritual defense, but on the other hand, Tachito is actually very ambitious. This guy's war horse fully enjoys all the elite talent blessings of his own legion.
From a certain point of view, Tacito gave up his Friesian horse as early as possible, and now maybe it is time to return to the three-talented horse.
However, riding a horse clearly showed superiority. Heavy infantry was too common in Rome, so even if Tacito was killed, Tacito would not give up his Frisian horse.
If you don't eat more of Pompianus' salary, you won't be able to afford the Almaden cinnabar mine in Spain that was destroyed by Pompianus, so just mess around and grind slowly. Anyway, you have been promoted to three talents three times, and your foundation has been polished.
It's very good, if you grind it slowly, it will be almost done in a few years.
From this aspect, it is enough to see that top mounts are also very troublesome for cavalry to consume talents. Of course, if you can follow the unlucky Rahul and give your mounts real talents, then it will be a great success.
I did not say.
Therefore, it was replaced by the seventh-generation ship used by Zhou Yu. To be honest, not to mention that this thing itself does not meet the standards of a mount. Even if it is a mount, the Xiliang Iron Cavalry cannot cover its own ideal defense. This size is really too big.
It’s outrageous and cannot be covered by individual talent.
"I didn't say that one person would use talent coverage." Li Jue chuckled, "We can also control this huge mount as a whole. We have never encountered such a large mount before. It is impossible for many people to ride on one horse.
, but this time we can have a legion of people on this big ship, so we can use our talents collectively."
This is a very outrageous situation for a normal legion. If any regular legion can do it, I am afraid that only a legion like Ultimate Danyang, which has developed its collaborative efforts to the limit, can barely be considered a whole legion.
The Xiliang Iron Cavalry would have been stuck at this step, but the outrageous fantasy condensation gave them the ability to unite.
The centaur with three heads and six arms is just a regular operation, and the sunflower evil god with thousands of hands and eyes is the appearance of a large number of Xiliang cavalry combined.
Although it seems a bit strange, if you think about it carefully, the Thousand Arms and Thousand Eyes Sunflower Evil God can barely be regarded as a whole. It is reasonable to use elite talents to cover the mounts, even if normally there are no such big mounts.
But doesn’t it exist now? If the seventh-generation ship is a mount, the Sunflower Evil God with Thousand Arms and Thousand Eyes is very suitable.
