The four Governor apprentices watched Teacher Marin give them a frothing explanation, a little ignorant. www.biquge.info They were frightened by Marin's endless intrigues and intrigues - could they use so many intrigues against an ignorant and backward native American?

However, it sounds like these tricks, if carried out, can indeed achieve twice the result with half the effort......

And Wiltz heard it even more foggyly, what Marin said about nickel and chromium, all of which he had never heard of. However, Marin didn't expect him to understand, but only told him that as long as they were smelted, nickel and chromium would be silvery-white metals. On top of that, nickel and chromium, mixed with iron, create a new variety of steel that does not rust - stainless steel.

What kind of red nickel sulfide, after being roasted at high temperature with air, will produce nickel oxide and irritating gas sulfur dioxide that can be reduced by a blast furnace, Wiltz heard it completely in the clouds.

In fact, Marin also ran out of ideas about Wiltz. Anyway, the smartest group of teenagers are almost finished learning elementary school knowledge. Now, Marin and others have taken the time to compile junior high school textbooks, add physics and chemistry to them, and select a group of civilian students with the best grades to teach them physical chemistry. When the time comes, when these people graduate from junior high school, they can replace Wiltz, who lacks knowledge.

At this stage, Marin really does not have an expert who is proficient in mining, so he can only let Wiltz take it first. And, for the sake of Heidel's face, it's not a big deal to give Wiltz a future. What's more, there is really no more suitable candidate than Wiltz now. In the future, if Wiltz is willing to learn new physical chemistry in his spare time, Marin will continue to use him. If he is not willing to accept new knowledge, he will have to make way for others. Anyway, a noble title and a manor can almost send him away.

As for Gaudard, the new young knight, the team he led was more like a jungle expedition, and there were many dangers along the way. Fortunately, Marin let him bring enough mosquito repellent toilet water, which can basically save his life. And, according to experience, Marin told him that to stay away from mosquitoes, it was best to camp away from the river. Because, mosquitoes mostly hide in the water and grass by the river during the day to escape the heat, and come out at night to suck human blood. Staying away from the river does make there fewer mosquitoes.

In addition, the dense tropical rainforest is also a hiding place for mosquitoes. Therefore, Marin planned to buy a batch of black slaves from the Portuguese colonists. In order to prevent the proliferation of black slaves in the future, Marin decided to buy only male black slaves, not female black slaves, so as not to give birth to a bunch of small black slaves in the future. As for whether the black slaves would have invaded Indian women and gave birth to mixed-race children? Don't worry about that. Because, the black slaves were locked up and slept at night. Want to play? You can do it yourself, or you can use your hands......

In any case, Marin would never make the mistake of the old beauty of history - in order to save money on the purchase of black slaves, let the black slaves reproduce on their own......

In this way, in a few hundred years, there will be no group of black masters in the Americas. Although, there may not be a good-looking NBA, but at least the security will be much better.

Marin is not a racist, but he is not fond of a race that is lazy, does not like to learn, and likes to break the law.

In his previous life, when Ma Lin was in China, he always saw a group of so-called brick family beasts, criticizing what kind of test-oriented education. However, if there is no strong pressure of exam-oriented education, and only the "quality education" of "everyone playing together" remains, then the Chinese people may have to degenerate into Lao Hei, who only knows how to be idle and do not learn and have no skills.

Ma Lin even wondered whether the so-called "quality education" of "letting children play" was an erroneous concept that Yankees had imported into Huaxia through some trusts to study in the United States, and deliberately let Chinese children play, so as not to catch up with and surpass Lao Mei.

You must know that Huaxia has never lacked this kind of 2505 who rely on relationships and money to study abroad, such as a certain Hehe, who went to study in the United States, and as a result, what did she learn? Sexology...... What kind of experts...... wiped the special code, and actually mixed into the Academy of Social Sciences and the Chinese People's Political Consultative Conference......

The question is, what did this thing do? actually relied on the identity of the CPPCC that he didn't know how to get it, and demanded the legalization of the foundation, and also abolished the "crime of gathering crowds to cause chaos...... This is clearly encouraging everyone to around......

This is the face of the international students of the special code, the things that have been learned are indiscreet, and they are still safe and sound in the country......

It is estimated that the theory of "quality education is play" is also put forward by this kind of "scholars studying in the United States", which is specifically harmful to China......

Belch...... Off topic...... Don't mention that pervert......

In short, as long as the black slaves are chained, there is no need to worry about them messing around. As long as you don't make a little black man, it won't be messy in the future. Although it is said that the black people can't catch up with the Chinese and Ah San in farming, they still have a lot of strength. This kind of strength is used to cut down trees, and that is the best.

What Marin needed was for the blacks to cut down all the trees on the road from Cologne to Panama City so that they could be used to repair the road. Once this road is repaired, it can be based in Panama City, set sail, and go directly to Daming through the convenient Pacific route. Then, the windfall profits from the trade of silk and porcelain will roll in......

……

The reason why Marin wants to take this route is because this route is most suitable for using the wind. In the days when the steam engine was not used for steamships, sailing ships sailed purely by the power of the wind. When there is no wind or headwind, it will be difficult for the sailboat to move forward, or even stop and drift with the current.

Thinking of the steam engine, Marin decided to go to Watt's steam engine research institute to inspect the progress of research and development......

In fact, after visiting Leonardo da Vinci's steam engine last time, Marin found that it was particularly similar to the original Newcomen steam engine, so after telling Da Vinci the principle of Watt's "solar and planetary gear transmission system" and the principle of the condensation circulation system, Da Vinci began to renovate the previous Newkomen steam engine.

After several months of improvement, Da Vinci had already made the "solar and planetary gear transmission system" and "condensation circulation system" at this time. Moreover, the tests have been completed and the results are good.

In fact, these two systems are not that difficult. After all, Marin explained all the principles, and if he couldn't figure it out, it would be too insulting to Leonardo da Vinci's IQ, who was one of the smartest people of this era. If Marin is not a traverser, it is estimated that he will not be qualified to carry shoes to others.

Next, it's the governor that Marin didn't even understand. Later, Leonardo da Vinci discovered that when the cone pendulum is too fast, the iron ball will generate a force outward, and then swing upwards against the cone.

Using this force, it is completely possible to design a connecting rod to control the valve of steam input, so that the steam output is reduced and the speed of the steam engine is reduced. But if the speed of the steam engine is too slow, the cone pendulum will fall, and then, because the connecting rod controls the valve, the steam in the pipe will increase the output and increase the speed.

After realizing this truth, Leonardo da Vinci quickly improved the steam engine and added a cone pendulum. Through the transmission system, the cone pendulum connects the rotating part of the steam engine output, and then there is a connecting rod at the top that connects to a valve in the steam output pipe. If the output speed of the steam engine is too fast, then the cone swing moves upward, driving the valve to close, reducing the steam output speed, and achieving the result of reducing the output rotation speed. On the contrary, the cone pendulum drops, the valve opens, and the output speed of the steam engine increases......

When Marlin passed, it was discovered that Leonardo da Vinci was testing the functionality of this flying ball governor and was successful. After discovering that the governor was finally tested, Leonardo da Vinci excitedly hugged the people around him. After hugging, Leonardo da Vinci was surprised to find that it was Marin who came......
