Donner changed his comfortable posture and said lightly: "The rich man has already decided not to give alms, and the beggar is very angry, and finally kills the rich man in the street. ”

Jason's face was full of astonishment, and he asked, "Why is that? How could that beggar kill the rich man who had been giving him alms?"

Donner smiled and said, "The first alms of the rich man really touched the beggar, but the second time, the beggar felt that the rich man's alms were normal, because the rich man is rich! The third time, the beggar began to take it for granted, this was the silver coin he begged for, and the fourth time, the rich man stopped giving alms, so the beggar was very angry, and thought that the rich man had taken away his silver coins, so he killed the rich man in anger." ”

"How so?" Jason was dumbfounded.

"Hehe!" Donner chuckled, "This story tells us that we can be kind and compassionate, and learn to help others, but we can't take others for granted." ”

"For example, these residents, we can give them food directly in exchange for their favor, but after they have eaten, should we continue to give them food? What about the third time, what about the fourth time? Will they take it for granted that we give them food? When one day we stop giving them food, will they be like beggars, thinking that we have taken away the food they deserve, and finally kill us?"

Jason was silent, he thought about it carefully and felt that it was really possible, people's selfish desires are infinite, habits are terrible, when people take the help of others for granted, once lost, they will think that the person who helped him has taken away his things.

"So, we can give food to the inhabitants, but we have to pay for it with their labor. Downer said solemnly, "Not only to gain their favor, but also to let them understand the value of labor from now on, and in the liberation regiment, only by working with their own hands can they obtain their own fruits of labor." ”

Jason took a deep breath and had a feeling of sudden enlightenment: "I understand, Captain." ”

Donner nodded, "Okay, you go and put up the announcement first, and by the way, help me get Anderson and the carpenter, I have something to find them." ”

Jason exited the room with the announcement.

Donner looked at Jason's back, wondering whether he should run a central league school, and slowly explained his thoughts and concepts to them more profoundly.

If you think about it carefully, you really think it's feasible, after all, as far as Hans Jasmine and the others are concerned, they don't understand the idea of emancipation and equality very well.

But for now, let's unify the weights and measures of Cancer Island first.

The unification of weights and measures will make it more convenient for the development of industry, and many industrial products can be unified in specifications, such as now, things like muskets, if a certain part is damaged, you can find parts of the same specification to replace, which will greatly reduce the scrap rate.

But...... What kind of weights and measures are used as universal and prescribed weights and measures for Cancer?

After thinking about it, Donner decided to use the international weights and measures he was familiar with and the corresponding units of measurement as the unified measurement standard for the Liberation Mission and Cancer Island.

Donner banged on the table in thought, and there was a problem in front of him.

Because in this world, there is no international standard length and weight equipment.

Donner couldn't tell how long a centimeter was or how much a kilogram weighed, so he couldn't just draw a line with empty teeth, or just find a stone to use as the standard for length and weight.

If this is the case, then the knowledge of mathematics, physics and chemistry that he has learned, even if he knows the answer, and then calculates, I am afraid that all of it will be disrupted.

"That's right!" Donner slapped his forehead, suddenly remembering his phone.

Donner vaguely remembered the standard size of his phone, which was a standard 150 millimeters in length.

Donner hurriedly found his phone, took out a piece of animal skin paper, and sharpened the tip of the quill pen a little more sharply.

Put the phone on the vellum paper, dip it in ink with a quill pen, and draw two dots along two paragraphs to get a length of fifteen centimeters.

After all, it is not laser calibration, and it is inevitable that the drawing along the edge of the phone with a quill pen is not the standard fifteen centimeters.

In order to reduce the error, Donner took a quill pen and drew a few more paragraphs according to different positions, and finally took a median value, and finally measured it with a mobile phone.

The cut fifteen centimeters are divided into fifteen equal sections, each of which is one centimeter.

The units of measurement are all decimal systems, so using ten centimeters as the initial length standard is the best choice.

With the length standard, the weight standard is not difficult, a cubic decimeter is equal to a liter, and a full water is a kilogram, and the international standard of weights and measures is thus calculated.

After a few moments, Anderson and the carpenter came over: "Donner, are you looking for us?"

Donner hurriedly stood up to greet him, and he had always had great respect for the craftsmen who had worked hard for the Liberation Regiment.

Donner smiled and pulled out the two stools, made a gesture of please, and said, "Uncle Anderson, Master Ulla, there is something I need your help with. ”

Ulla, the carpenter, was accustomed to being a slave, and was a little afraid of Donner, the pirate leader, and he looked a little cautious, habitually bent up, and said that he did not dare.

Anderson asked, "What's the matter?"

Donner considered the words and said, "That's right, I found that all the masters use different weights and measures, and this situation is extremely confusing, and for the sake of convenience, I have decided to unify the weights and measures in Cancer Island, what do the two masters think?" ”

Master Ulla was silent, but there was still some disapproval in his eyes, these craftsmen have been accustomed to their own measurement methods to create utensils for a long time, how could they be willing to change their own methods and measurement methods at will.

Anderson asked puzzledly, "What's the use of unifying weights and measures, don't everyone have their own methods?"

"Yes!" Donner explained with a smile, "Think about it, for example, when you buy and sell things, everyone uses different weight units, which undoubtedly makes the transaction cumbersome, and for example, uncle, the barrel and other parts you create will be different from the length of the other blacksmith masters, if one part of a musket is damaged, the whole gun will be scrapped, if everyone can use common weights and measures, and use the same standard to build things, is it that the damaged parts can be replaced with each other?"

Anderson and Ulla were lost in thought, and when they thought about it, they thought it made some sense.

Donner laughed and said, "I know it's going to be hard for you to change your measurement methods and build things right away. Why don't you use it according to the standards I set for a while and try the results?"

Anderson and Ulla looked at each other and nodded.

Seeing that the two of them agreed, Donner handed the ten-centimeter animal skin paper made on the table to Master Ulla, and said, "You see, I define the length of this section as one decimeter, and ten decimeters are called one meter, and one thousand meters is equal to one kilometer. ”

"A decimeter is divided into ten parts, and each part is a centimeter, and a centimeter is divided into ten parts, and each part is a millimeter. ”

Master Ulla looked at the animal skin paper in his hand and asked aloud, "What about ten parts of a millimeter?"

Donald laughed, "How about if Master Ulla can divide a millimeter into ten parts of the same length, and I reward you with fifty gold coins?"

With the industrial standards of another world, if you want to accurately divide a millimeter into ten parts, I'm afraid it's impossible right now, right? You know, this is something that can only be done with an optical measuring instrument.

Ulla thought about it, only to realize that one millimeter was already very short, and it seemed impossible to divide it with the naked eye.

Downer continues: "When a porcelain is fired with an internal dimension of one decimeter, the porcelain capacity is defined as one liter or one cubic decimeter.

The porcelain is filled with water without impurities, and the weight of water, which I define as one kilogram, is the same as the unit of length, in the decimal system, which can be increased or decreased indefinitely. ”

"The length on this piece of vellum paper was for Master Ulla to help make it out of a wooden plank as the initial standard, and then to make all the weights and measures. ”

Master Ulla agreed, and then exited the room with Anderson, ready to build weights and measures immediately.
