Destiny Only Han

After seeing off Zhang Buyi, Liu Ying sighed invisibly.

This is not to despise the poor man, but to regret the shortage of materials.

Gravity pendulum clocks are limited by mechanical restoring force, so they can only stand still, and cannot be used for sports timing, and cannot obtain a stable source of restoring force in complex and changeable sports environments.

After all, as long as mechanical clocks are related to sports, they are basically balance spring mechanisms.

The recovery force of this structure comes from the elastic deformation of the hairspring, which requires the hairspring to have very stable elastic properties for long-term work in various temperature, humidity, and salt spray environments.

Therefore, the nautical clock cannot be made.

The nautical clock is not only used to indicate the time, but more importantly, it is used for navigation and positioning.

The matter of navigation, to put it bluntly, is to solve two problems. Where am I?where to go

There will be various reference objects on land. At this time, relying on guides and maps can easily solve these two problems.

But out in the middle of the ocean, when there's water all around, it becomes a matter of life and death.

A long time ago, navigation was limited by technical conditions, and it was impossible and would not leave the coastline too far, because it could be positioned with reference to the land and landmarks on the continental shelf, such as islands.

The reason why the Greek city-states have traveled all over the Mediterranean Sea is because when the weather is fine, standing on a boat and looking up, you can always see one or a long list of islands in the distance.

It is very simple to touch such an island one by one, colonial trade.

Well, the Austronesians, who were earlier than the Greeks, used the same method to set off from South China in a tub-like canoe, sailing all the way across the ocean, and traveled all over the South Pacific. In this way, they touched New Zealand, Polynesia and even Ran to Madagascar in the western Indian Ocean...

But when it comes to the ocean where there are no islands to jump to, you can only rely on the stars in the sky as a reference to determine your own position and find your own course.

With the nautical clock, you only need to adjust to a relatively accurate time when you set off, and then put a stick on the boat, and when the shadow is the shortest, it will be twelve noon local time.

Then, according to the longitude of fifteen degrees and one hour, you can judge your longitude.

And by measuring the solar altitude angle at noon, and then looking up the declination angle of the day from the astronomical calendar, the latitude is there.

With longitude and latitude, you can determine your approximate bearing and then find the correct path.

But there is another difficulty, that is, if you want to travel across the ocean with the help of the nautical clock (astrology), you need a captain who has received a certain amount of education, especially good at calculation.

Therefore, this is another reason why Liu Ying desperately hugged money.

Education is a bottomless pit.

The purpose of Liu Ying's desire to train captains capable of ocean voyages is naturally to open the era of geographical discovery in the Han Dynasty, while going west to Europe by land, and going east to the New World by sea and land.

The difficulty of going to the New World from the Han Dynasty is not too big, but it is not small, and a key ocean current needs to be used.

Kuroshio.

The so-called Kuroshio Current refers to the western boundary current in the North Pacific subtropical general circulation system, which has the characteristics of strong flow velocity, large flow rate, narrow flow range, deep extension, high temperature and high salinity. named.

The source of the Kuroshio Current is located in the southeast of Taiwan and the sea area east of the Bashi Strait. The mainstream goes northward along the east coast of Taiwan, enters the East China Sea through the waterway between Suao and Yonaguni Island, advances northeastward along the continental shelf of the East China Sea, and then a branch flows northward along the coast and goes southward. The Thousand Island Cold Current (Oyashio) converged and turned eastward, becoming the continuing current of the Kuroshio Current, which extended into the North Pacific Current near the Northwest Pacific Rise and flowed to the west coast of North America.

As early as the Warring States period, some people had discovered the Kuroshio. In the Sui and Tang Dynasties, the ancients may have had a model knowledge of this powerful ocean current in the East China Sea. In the Southern Song Dynasty, there were clear records.

For example, "Chunxi Sanshan Zhi".

But the crux of the problem is that this is a powerful ocean current that flows eastward and never returns, which can be called a one-way ticket.

After all, returning from the west coast of North America, when returning from the northern line of Alaska, you will face the obstruction of sea fog and icebergs, which is no different from death. merchant ship.

And return by the North Equatorial Current, the way is farther and there is almost no land support.

Therefore, in terms of exploring the New World, compared with Asia, Europe has unique conditions.

Every route in the triangular trade has a tailwind and can be profitable. The most important thing is that it is limited by water sources and climate factors. The essence of American agriculture is on the east coast...

Liu Ying shook her head slightly in silence, but immediately raised her head proudly.

He is a systematic blue man!
It was not easy to open up the New World and Australia in the agricultural age, but the map in his hand marked the locations of some local mineral deposits, especially the gold mines.

In this way, colonial strongholds can be established through the gold rush, and the population can be transferred from another populous country and a long-established population-exporting continent to complete the early development and pioneering work.

Then, stay away!
As for the problem of color pollution, there is actually no need to worry about it.

Anyone who has raised cats and dogs knows that it is necessary to castrate pets if they want to keep their pets alive for a long time without getting sick, and not to breed one litter after another, dragging down their energy and money.

According to research, whether it is a human or an animal, physical development and sexual development are inversely correlated, that is to say, the earlier castration, the larger the body size, and the higher the working efficiency.

This is also the reason why the ancient imperial palace used more eunuchs than maids.

So, all it takes is a simple minor surgery.

This is all for their benefit!

Before that, we need to accumulate enough experienced captains and sailors in the process of crossing the East China Sea, and speed up the construction of Whale Island, striving to expand to the east of the island as soon as possible, and build a harbor there, so that we can directly raise funds there. Supplies such as food are used to support ocean voyages.

Well, the reason why traveling to the New World requires ocean voyages instead of walking along the coastline is mainly because the straight line between two points is the shortest.

When the sailing time is calculated in months, the sailor's mentality can easily collapse.

Even in the era of great voyages, there are still many crew members who have lost their minds to vote, give up sailing, throw the captain into the sea to feed the sharks, and then drive to the nearest port to sell the ship and cargo for a cent. Break up and go their separate ways...

As for Zheng He's voyages, it was mainly because it was a waterway that people had traveled for thousands of years, and there were anchoring points everywhere.

And the officers and soldiers of the Ming Dynasty were rich, so they could find a place to vent their anger and calm their anxiety after they went ashore.

Well, just be careful not to get dizzy and ask Zheng He to go with you...

In this way, you don't have to go again in this life.

....................................

To the north of Gui Palace, near the arsenal.

Even though there are still sporadic snowflakes floating in the sky at this moment, there are still crowds of people here, and there is a long queue that can't be seen at a glance.

In the crowd, a short and puffy figure wearing a felt hat and a fox fur cloak poked his head out of the line from time to time, looked around and murmured.

"Slow death, slow death! Smelly brother insists on making everyone line up to get the money, and I will deal with him after I go back!"

This person is Liu Le.

She braved the snow to come here to line up today just to receive the interest on the Whale Island Development Bond she bought earlier.

In order to sell the second batch of bonds, Liu Ying focused on driving up the stock price of the bonds. She deliberately asked these profit-seekers to line up in front of people, so as to attract the envious eyes of others, and then follow their example to snap up bonds.

Because of this, before the interest was paid, some black and evil forces around Chang'an City who had criminal records and might commit robbery and theft were visited by Fengcheng law enforcement officials, and they were guaranteed that they would never commit crimes.

And those stubborn people were directly wiped out by the Chang'an garrison who came after the law enforcement officials left.

After all, the Han Empire cannot have such a powerful person...

So when receiving money today, even if the middle class is not a wealthy family, they still dare to show off to the people around them with their own bonds...

The reason why little Lolita didn't let the servants around her do it for her was because it was a legitimate opportunity to go out of the palace to join in the fun!
She will never let go of this opportunity!

It's just that beside the little Lolita, there is still a tall and fat figure standing.

Liu Fei.

He came here in person, one is to escort little Lolita, after all, he is the eldest brother, and he has to shoulder the responsibility of protecting his younger siblings.

But more importantly, it is for Cao's...

Little Loli stomped angrily holding the box, and suddenly saw a pretty figure in a white cloak appearing on the other side of the street.

"Sister Xu, here, here..."

Xu Negative's eyes lit up, he looked at the long queue, and after struggling for a while, he resolutely walked over to Little Lolita.

"Sister Xu, are you also here to collect the money?"

Xu Negative was silent for a while, and began to regret coming to jump in line.

The money is not revealed, and once people know that she is rich, it will be difficult to charge a high price for divination money. The important thing is, what if there is a sister who is very good in her daily life to borrow money?
Borrow, how distressed!

If you don't borrow, won't the sisterhood be gone?
It’s just that if it’s gone, it’s gone. The key is that her sisters will often introduce her business, such as calculating marriage, calculating whether someone is a good match, etc. The unit price is high, and the simple big list...

It's just that when Xu negative was silent, little Lolita inadvertently glanced at the bonds that she hadn't had time to put back, widened her eyes and said:
"Wow, sister Xu, why did you buy so many? I heard from my younger brother that when the bond was sold to the public, not only the fixed amount, but also a lottery was required. You are so lucky!"

"No, no, don't say that. I'm just picking it up for someone else..."

Xu Negative explained with a little embarrassment, he was just thinking about the fact that my Yin-Yang family has countless warriors, do I have to tell you?
