In the past six months, Zhu Mingzhong suddenly suffered from insomnia for some reason. I don't lie down until late every day, and I always wake up early. Because of this, in recent times, he has often rested alone.

In the morning, after waking up in the study again, and then starting to run, and thinking while running, this habit of morning exercise has now spread from the imperial palace to the people, not only in the student union of the academy, but also in many officials.

After running around the small lake in the Imperial Garden for a few laps, Zhu Mingzhong, who had run for almost ten miles, went to take a bath again before returning to the study again. Soon a female officer brought him breakfast for the day. Despite being a palace breakfast, it was still very simple, completely different from the luxury of one might imagine – a glass of milk or a bowl of gruel, two plates of stir-fried vegetables, a basket of vegetarian buns, and a clear egg.

In terms of eating, like the emperors of the Ming Dynasty, it can be called "not exquisite", breakfast is eaten quickly, after breakfast, Zhu Mingzhong began his own day's work, is to read the summary of information and then the important official documents of the imperial court.

I don't know why, in the last period of time, Zhu Mingzhong found that deep down in his heart he really couldn't bear this work. As soon as he thought that this job was unavoidable, his mood became a little irritated, and he preferred to stay in the laboratory if he could.

Almost every day, Zhu Mingzhong walked into the office with this emotion - that is, the imperial study, which was a large room, flanked by ceiling-to-ceiling bookcases, with a thick and fluffy carpet on the floor, and in the room there was a wide and long writing desk, or the imperial case, a large globe placed on a black wooden shelf not far from the imperial case.

Every day, the same work is repeated, which is the most boring part, and after a long time of work, Zhu Mingzhong found that he seems to have a special function - he can clearly remember the content of documents and intelligence, and can also remember them word by word, which is an ability that only has after crossing over.

If you had this ability before the crossing, you might have been admitted to a prestigious school a long time ago.

However, despite this ability, Zhu Mingzhong still finds that he seems to have begun to hate Kumon now, because everything here is so boring, in the 17th century, everything was boring, and even sometimes, Zhu Mingzhong always misses another time and space, nostalgia for the prosperity of that era, which is not available in this world.

"Wait until ...... When the time comes, it is not impossible to learn from Wanli. ”

muttering like this, Zhu Mingzhong even had the idea of wanting to be a "faint king".

Even, he has been "working hard" like this, for example, he canceled the early dynasty that was equivalent to torture for the emperor and hundreds of officials, and he would not be like his "father", meeting ministers in the open air Yuntai edict and getting something "Yuntai edict right". Perhaps, he got rid of these mundane things, but as an emperor, he still had to read a lot of memora. And this job is the most boring, and even just flipping through these boring twists and turns is a kind of torture for Zhu Mingzhong. In short, he now dislikes this "job" more and more.

Although Zhu Mingzhong believes that even if he doesn't need to do it himself, as long as he grasps the direction, the Ming Dynasty can become another empire on earth in the next few decades, occupying the most extensive land in the world. Moreover, the Ming Dynasty, which has entered the dawn of the industrial revolution, will allow the entire country to continue to develop and be ahead of the rest of the world.

However, there seems to be some uncertainty, after all, there are too many uncertainties in the future. Perhaps, it is precisely because of this worry that Zhu Mingzhong's insomnia is the root cause.

Although the work of reviewing and reviewing the folds seems a bit boring, this work still needs to be continued, even if the job is unpleasant.

The twists and turns on the case involve all aspects, but for Zhu Mingzhong, as the emperor, the twists and turns that are replied to every day are often three big characters.

"Got it."

Not only because the cabinet has already given solutions to the problem, but more importantly, many of them are actually very boring. Although the cabinet and the general political envoys have filtered a lot of twists and turns, Zhu Mingzhong, as the emperor, can still see some twists and turns that make him helpless.

For example, now, the excerpt sent by the governor of Fujian and Zhejiang is a simple excerpt, a fold of more than 100 words, without the slightest nutrition, just saying one thing - Taiwan introduced American fruits, named "pineapple", dedicated to His Majesty.

"I know, last year, there were already canned pineapples in Taiwan that were shipped and sold in the capital, and I won't send them in the future!"

After completing this one, take a look at the side again, and there are still a bunch of please fold. What is Please Ann Fold ? It's just a sentence: "Is Your Majesty okay?" And Zhu Mingzhong, as the emperor, replied with the two words "Zhen'an".

Looking at these boring twists and turns, Zhu Mingzhong had only one thought - to be a hands-off shopkeeper and send this kind of thing to others to ask.

"I'm safe, I'm ,...... Won't he be able to keep me quiet for a few days? ”

Annoyedly, he wrote the word "Zhen'an" on the fold, and Zhu Mingzhong even doubted at this time that if he had to reply to some such boring greetings on his mobile phone for an hour at this time.

And this is the source of his most unpleasantness.

In fact, Zhu Mingzhong didn't want to reply, but some of them were favors, and even Fang Yizhi, who was the governor of the Northeast, also handed over a letter of invitation if he had nothing to do, and there were only a few words in the fold.

"Is Your Majesty safe?"

As the emperor, Zhu Mingzhong has to be perfunctory even if he doesn't want to, otherwise he will hurt the minister's heart, after all, for the feudal officials in the border area, this kind of invitation is not only to let His Majesty not forget himself, but also to tell His Majesty that the local wind and rain are smooth, and the people live and work in peace and contentment, so there is no need to worry.

Therefore, even if he obviously doesn't like these excerpts very much, Zhu Mingzhong often has to pretend to be confused patiently, and solemnly reply with the two words "Zhen'an", and then, if there is a telegram, reply by telegram, and if there is no telegram, first send it to the nearest telegram station, and then send it through the post station.

"Just these two words, at least one or two silver postage!"

lamenting the waste of postage, Zhu Mingzhong could only be patient and give instructions, as an emperor, he also had the helplessness of being an emperor.

Of course, not all the twists and turns are so "boring", and Zhu Mingzhong prefers to read the report submitted by the academy rather than the officials.

“…… In order to solve the problem of longitude determination at sea, as early as a hundred years ago, King Philip II of Spain proposed a bounty for scholars who solved the problem of longitude. At about the same time, the Dutch parliament offered a prize of up to 30,000 florins to settle the longitude problem, and Portugal and Venice were also said to have offered varying amounts of longitude prizes, which was popular in Europe...... However, as the Ming maritime trade became more and more frequent, the longitude of determining the position of ships at sea became more urgent, and in order to promote the development of the Ming navigation and colonization, it was suggested that the royal family should follow the example of European countries and use bounties to find a solution...... to encourage scholars to engage in this research. ”

Looking at this piece of music from the Zhongdu Observatory, Zhu Mingzhong's eyebrows raised slightly.

Longitude!

Finally someone is asking this question!

In fact, as early as when Jiangbei was first determined, Zhu Mingzhong had seriously considered the problem of longitude, and in another time and space, the time method and the moon distance method are the two ways to solve the problem of longitude more than 100 years later. Because the time method requires a well-constructed marine clock, Zhu Mingzhong chose the moon distance method that he knows better. Compared with an expensive marine clock, a high-quality sextant, plus a "moon distance", the price is extremely low, from a practical point of view, the "moon distance method" undoubtedly has a huge advantage.

The trajectory of the moon, another pillar of the lunar distance method, was historically completed by the German Meyer. In 1755, Meyer produced a Lunar Table that accurately described the position of the Moon at any given moment, referring to the calculations made by the Swiss mathematician Euler on the Moon's orbit. Euler was a genius mathematician who solved a mathematical problem that was a headache for Newton by describing the relative motion between the earth, the sun, and the moon with a beautiful set of equations.

As early as a few years ago, Zhu Mingzhong wrote that complex and beautiful set of equations with his recollections, thus completing the calculation of the lunar orbit.

"You can ask the observatory to make a copy of the Lunar Table first."

Zhu Mingzhong said to himself.

The observatory located in Qinghe Academy, three years ago, under the leadership of the director of the observatory, Xue Fengzuo, and others redrew the map of the Ming Dynasty, which was also the first accurate map of the Ming Dynasty. The current observatory is home to some of the best astronomers and mathematicians of the Ming Dynasty, and they are fully capable of completing this task.

"I first compiled the "Moon Table", and then used the students of the mathematics department of Qinghe Academy to calculate the lunar distance data for the whole year. In this way, it should be possible to compile the Nautical Almanac and Astronomical Ephemeris......"

Recalling another time and space, the method used by Mascalin to solve the difficult problem of calculating the "moon distance method", Zhu Mingzhong's lips were raised, standing on the shoulders of giants, he could indeed solve many problems.

Thinking of this famous sentence, Zhu Mingzhong naturally thought of Newton, who had already served in Qinghe Academy, and now he has become a naturalized Ming man and has become the "Professor Niu" of Qinghe Academy.

"Professor Niu......"

Thinking about this Professor Niu, the corners of Zhu Mingzhong's lips raised slightly, and he naturally thought of the observatory again, and of course, the famous Greenwich Mean Time and the zero degree line in later generations.

"In the future, the zero degree line on the earth will definitely be the "Qinghe zero degree line" ......"
