Chapter 248: No need to trouble Leibniz

The arrival of the O1 paddlewheel sailboat can be regarded as the first step of the Hantang Group to the 6th exhibition of Mingda.

Its symbolic and practical meaning is not important...... Hantang Group noted this time:

At 5:25 p.m. on January 15, 1649, the side of the O1 paddlewheel sailing ship officially docked on the dock of Xiamen Port, which was exclusive to the Hantang Group.

Yongsheng Bo Zheng Cai, who had been waiting for nearly three hours, looked calm at this time...... He waved his hand back gently, and immediately firecrackers rang out on the pier, and at the same time gongs and drums began to roar...... There are also two folk dragon dance teams, which also began to dance, and they kept posing for the double dragon playing with pearls at the same time, which is the emblem on the flag of the Han and Tang groups...... This requires the two dragons to be erected in order to imitate them, and the movement is not small.

It seems that the people here have long been familiar with the banner of the Hantang Group......

This time I came to work at Xiamen Commercial Station, except for Sima Jianguo and Jiang Tiesheng, the rest of them all signed up voluntarily...... The four security team members also volunteered to take on security and safety duties, as well as the potential for recruitment and possibly as military advisers...... Of course, it depends on how the situation changes...... In addition, there are the internal affairs of the security department itself, and the tasks of the two departments are definitely different.

The regular staff of Xiamen Commercial Station are two people, one named He Yang, who was originally a temporary worker in the power grid department of the world, and he couldn't turn regular after seven or eight years, but his life is still good, and people eat meat as regular workers, and they can also eat some meat foam......

Later, when the leader changed, all the people like them were replaced, and at a certain time in that world, even the opportunity to eat meat foam was a good opportunity...... He Yang has worked part-time in the east and west, electronic maintenance, and mechanical maintenance...... He also resold pornographic films...... This is just forced by life, in fact, he is still very motivated, and during his time as a temporary worker, he also got a college certificate......

The other is Li Zheng. Li Zheng's usual job is to maintain the operation of the network. His hobby is fiddling with mechanical computers, often making them by hand...... Then go online and communicate with your friends.

He is different from Ye Zihong, who makes steam engine models and sells them online, and he treats them as playing and making money.

Both of them originally had similar hobbies...... can be friends, but Ye Zihong likes dogs, and Li Zheng likes cats, which makes both parties unhappy with each other's online signatures.

Li Zheng said: "Cat, it is content with loneliness and calm...... It can see the world with its delicate eyes...... Never try to please others......"

Ye Zihong said: "Dog, it is always loyal and enthusiastic...... It can devote all its body and mind to its master, and will never betray its master......"

The two of them rarely spoke again......

Ye Zihong's friend Su Libai said: "Is it important to like a certain animal? ”

Ye Zihong said: "It's very important, it shows what kind of emotional return he wants to get...... For example, I like you as my friend. ”

Su Libai didn't react at the time, and said, "No wonder you like dogs, dogs are good." ”

Li Zheng's friend is He Yang, he smiled and didn't say anything about the dispute between the two cats and dogs, and still worked with Li Zheng on the design and processing of mechanical computers......

The first real computer was the mechanical computer of the famous scientist Pascalming. Born in 1623 to a family of French mathematicians, Pascal lost his mother at the age of three, and was brought up by his father, who was a tax collector. From an early age, he showed a keen interest in scientific research.

The young Pascal has a deep affection for his father, and he watches his elderly father struggle to calculate the tax rate every day, and he wants to help do something, but he is afraid that his father will not be at ease. So, the future scientist came up with the idea of making a machine for his father that could calculate taxes.

At the age of 19, he learned about the first mechanical computer ever built.

Pascal's computer is a series of geared devices that resemble a rectangular box that can only be turned by tightening the strip with a key like a children's toy, and can only be used for addition and subtraction. However, even if you only do addition, there is a "every ten" carry problem.

The clever Pascal employed a ratchet device in the form of small claws. When the positioning gear turns towards 9, the pawl gradually rises, and once the gear turns to O, the pawl "clicks" down and pushes the ten-digit gear forward one gear.

After Pascalming's success, five of these computers, known as the "Pascal Adder", were produced in a row, and at least five of them are still preserved.

For example, Pascal's computer prototypes can be seen at the Ecole Polytechnique in Paris and the Science Museum in London. It is said that in the Palace Museum of the world, there are also two copper replicas, which were gifts from foreigners to the Empress Dowager Cixi, and "Lafayette" understood its mystery, only regarded it as a Western foreign toy, hidden in the deep palace.

Of course, Li Zheng disdained to copy such a simple mechanical computer, not to mention that it could only calculate addition and subtraction -- even if the later Leibnizian mechanical computer could be multiplied and divided, he did not care about it. The big guy had to increase his size due to the stepped shaft - a meter long, which was too bulky.

But we can produce it first, and maybe we can ship it over and sell it for a good price...... This was He Yang's idea.

Li Zheng said at the time: "The price is not very important, if the Ming craftsmen learn to add it, maybe they will have a good livelihood......

It is said that Leibniz's calculator and its design ideas at that time aroused great interest among the Academy of Sciences in Paris and the Royal Society of London.

For this, in 1673, Leibniz was elected a member of the Paris Academy of Sciences and a member of the Royal Society of London.

It was also in that year that the prototype he made was sent to London for exhibition, causing an unprecedented sensation.

Leibniz was also deeply thrilled by his heavy reform of computing tools, which he said made him "very happy".

"Astronomers don't have to train the patience needed to calculate," he enthused...... If you use a machine, you can leave this kind of work to anyone else.

Li Zheng and He Yang really wanted to leave these things to themselves, so that they wouldn't need to trouble Leibniz.

Li Zheng and He Yang spent their rest time copying and refining a hand-cranked computer from the Dutch company Philips in 1936 as a binary hand-cranked mechanical computer.

It is used to input numbers from the keyboard and can do four operations: square number, cubic number, open square, open square...... It is not small.

But if you want to enter trigonometric functions and logarithms, you need to look up the table. And if there are parentheses in the calculation, it is extremely troublesome. In use, it should be shaken a few times at any time, and it should be shaken a few times backwards, and it should be recorded with a pen and paper. These are its drawbacks.

However, because of its simple structure and ease of operation, this hand-cranked mechanical computer was once commonly used and continued for a long time - I heard that it was used in the development of the atomic bomb in the 50s.

It was by chance that Li Zheng got a hand-cranked mechanical computer, and he regarded it as a treasure and began to study the mechanical computer.

A technician asked curiously, "Is this thing easy to use with an abacus?" ”

Li Zheng replied softly, "Can the abacus evolve?" It can only be practical forever ......"

β€œβ€¦β€¦β€

Li Zheng also said: "It contains logical relationships, regular relationships, and even transmission methods and machining capabilities...... Can the abacus have the possibility of sustainable exhibition?"

The technician thought about it carefully, but was speechless.

Which is more important, practical or evolutionary? That's another fucking problem!

Borrowing the machining level of the Red Star Industrial Zone, the two have no problem in imitation, but they are not willing to do so - often think, are we not as good as the ancients more than a hundred years ago? How to improve it - to make it more convenient, or at least to change it to automatic, such as punching - the subsequent research turned to the theoretical, and the two of them felt that the work on a daily basis was a bit trivial.

So while recruiting people to go to the Xiamen commercial station, the two decided to go together, among a bunch of Ming people, no one came to bother themselves, right?!

As for the required information, a handheld is sufficient.

The Hantang Group made countless assumptions, and even considered whether Zheng Chenggong would advance the murder of relatives in the Mid-Autumn Festival next year, but in the end, there was no problem with the safety - the third brother lived happily in Taiwan.

Hantang Group has prepared a BT-119 general-purpose short-wave radio station for this Xiamen commercial station.

Before the crossing, this was the main equipment of the world's field communications. It itself has an all-aluminum alloy structure, internal building block units, good shielding, military supplies are all cost-free, and all plug sockets are gold-plated and silver-plated.

It has the characteristics of easy carrying, simple operation and strong ability to adapt to the environment, which can be used when carrying and traveling, and can be used fixedly.

At that time, a large number of equipment was used in the troops, and it may remain one of the main equipment for field communications for a long time to come.

Its working frequency is 3o-8omhz, FM, the size and power are adjustable, and it has the function of squelching noise. Built-in antenna, communication distance 1o~2o km; Equipped with 15 meters oblique antenna, the communication distance is 2oo kilometers; Equipped with 44 meters of bipolar antenna, the communication distance is 5oo kilometers; Equipped with a security handle, it can encrypt digital jΓΉ and voice communication.

Of course, the latter point is no longer useful, and in this day and age, it seems that until they use the radio to rot, no one can crack their communications. That's for sure.

In terms of energy equipment, the emergency equipment is a set of hand-cranked motors with an electric power of 100 watts, which can provide energy for the radio station in case of urgent need, and of course can also charge lead-acid batteries.

The main energy equipment is a set of small solar power equipment, of which the eight square meters of monocrystalline silicon panels, the average power is 1ooo, which is the largest component. The other control and inverter equipment are all miniaturized equipment - wild survival equipment sold in Japan, and the quality is reliable.

Small wind turbines are also available, but they are used in Xiamen, I am afraid that it is too eye-catching.

There are only three such solar power plants in total, which shows how much hope they have for this trading station.

Other daily necessities will not be explained one by one, and it is completely guaranteed that after they get off the ship, they can directly stay in the newly repaired commercial station.

Before going out or at dawn, Chairman Wu Dapeng deliberately got up early in the morning to see off these pioneers, although everyone was voluntary, but they could not help but feel the attention and care of Hantang Group.

Qi Guosheng, the manager of the communication and information company, also came, he actually didn't want Li Zheng and He Yang to go, it was too dangerous, and it was a bit inappropriate for two people to go into business--but he couldn't convince the two boys.

Before getting on the ship, Chairman Wu Dapeng said: "If there is an unexpected situation, don't care about anything, the most important thing is to protect yourself!" ”

The men laughed and thought to themselves, "We're six men, six pistols, four AK47s, two boxes of grenades, and by the way, six Myoto security guards, six Type 1649 rifles -- as soon as the news gets out, reinforcements can arrive in five hours at the earliest, and of course modern equipment will be used at this time.

What else could there be like about it?

Without further ado, when the O1 sailboat went all the way to the port of Xiamen against the north wind, everyone walked out of the cabin and looked curiously at the bustle on the dock, and there was some inexplicable excitement in their hearts.

But the most excited belonged to the six Akito security guards who came with him.

They really didn't expect to see Yongshengbo and Dingyuan Marquis greet them on the dock at the same timeβ€”the six of them unconsciously straightened their waists.
