Why did Fan Jingjing insist on Jiang Blacksmith joining the research?

Even if the current iron tools and iron ore are relatively expensive, it is not easy to obtain?

Because in Fan Jingjing's eyes, pottery or glass are not good raw materials for canning.

In particular, the traffic level of Datang is very poor, if you use pottery or glass, you must spend a lot of time and energy on the protection of transportation, if you don't protect well, it will be broken or overturned along the way.

Even if it is transported by ship, not every place can go by ship, and the vast land in many places can only be transported by land, but once it is transported by land is a big problem, if canned food cannot enter every household for storage, then the advantages of canned food will be much less.

Therefore, the final solution to the problem must rely on new cans.

And in Fan Jingjing's impression, the cost of canned food is actually not very high.

The storage of minerals is still very high, and more importantly, cans can be recycled and reused, so the cans sold can also be recycled, and then turned into raw materials again, and the waste of the environment will be much less.

The important thing is that there are actually several iron mines in the scope of the Fan family's manor, and Fan Jingjing also sent people out to inquire whether some of the iron ore areas he remembered had been developed, and if not, he would find a way to buy that piece of land, do farming on the surface, look at the minerals in private, find out these minerals, and then choose the appropriate place to make their products.

Of course, Fan Jingjing hopes to be able to make products, including the entire canning equipment, but the entire canning equipment must make a lot of machinery, and the whole difficulty will be very high, and Fan Jingjing has no way to expect the product to come out in a few months.

Fan Jingjing has been mentally prepared, it may take more than ten or twenty years, and in the end, if she can make canned food, Fan Jingjing will be considered a success.

At this stage, only pottery and glass bottles can be used instead.

This is destined to be a general level of difficulty, and the cost will be maintained at a relatively high level.

There is no way to automate the productivity of the workshop.

In fact, in the era of science and technology, there is no problem at all with pottery and glass bottles, because in the age of science and technology, there are many ways to ensure that the glass will not break when transporting, not to mention that the road they walk is friction technology through reasonable calculations, neither too high, nor too low.

The reason why it is not too low is that the car needs to brake while driving, and if there is no friction coefficient but a smooth surface, it will be difficult to brake.

Once the brakes are difficult, many accidents will happen.

If the coefficient of friction is too high, it will cause a lot of jitter in the whole process of progress.

Even if rubber tires are used, there is no way to make everyone feel stable when sitting in the car, and when the car moves, the engine is in motion, and there is no way to gradually reduce the kinetic energy of the engine in other directions.

It can only maintain a certain steady state.

Therefore, the roads made of cement are not even suitable for walking in the era of science and technology, because the cement of the road walking in the era of science and technology is unqualified, and it must be paved with asphalt to really meet the needs of automobiles.

However, there is no place for high-speed driving, and there is no big difference between cement and asphalt, and people do not have too high requirements for such a detailed transportation difference.

When people have needs, they will have the desire to change, and there is no way to change, people will begin to solve the reasons for not being able to change one by one, until one day their needs can be satisfied.

However, not everyone has the ability to change.

Fan Jingjing knows that people's needs are very strong, but too strong needs will make people forget what is the most important thing in front of them, because a person's energy is limited, there is no way to develop everything, only to meet their own life, needs are the priority, when the needs of life are not satisfied, people have no time to think about other things.

The vast majority of people in Datang have no way to be completely satisfied in life, and eating enough has become a problem, their thoughts every day are how to be full, only people who are full and have nothing to do will begin to think about other things, but once most people have free time, most of the things they want to do are to enjoy, only a small number of people will feel that only enjoyment will also make their spirits sluggish, and his spiritual life must have a higher degree of development, and these people will begin to find ways to do bad things. Or find a way to do research and change the current situation.

Now the population of Datang is still very small, and if these small numbers are put in the era of science and technology, they will not even be able to live in a county seat.

The county is home to a dissatisfied population, and it is okay to concentrate their development in one direction, but if each of them has different interests, has different breakthrough points, and even does not share or study with others because of the principle of confidentiality, it often takes a lot of time under the power of one person.

Scientific research in the era of science and technology has changed very much, they use hundreds of people to solve a problem together, even so, the problem of their homework is not only a few months to be able to work, sometimes it takes several years and some time they are constantly making mistakes, correcting and breaking through.

With new breakthroughs, we can take a step closer to our goals.

When the same thing is developed, these things will also become a stepping stone to something new, a new direction or a new obstacle to people's thinking.

Because later generations pay attention to intellectual property rights, the protection of intellectual property rights is helpful, because people can know that their wisdom can form wealth, form wealth, improve their own lives, and make people more motivated, but the formation of intellectual property rights is also an obstacle, because your development cannot be completely developed from your own head out of thin air, many things must be improved by contacting other people's thinking, and when you improve with the help of other people's thinking, you must use other people's intellectual property rights. But if you want to take advantage of someone else's intellectual property, you have to pay a cost.

Therefore, the biggest problem of many scientists in later generations is that if they want to study something, or even the paper they want to write, if they want to accept the recognition of others, then they must buy other people's intellectual property rights, have the right to use it, and develop their own technology.
