A few gentlemen who are good at chemistry have long had a heated discussion about the two concepts of manufacturing nitroglycerin and manufacturing nitroglycerin on a large scale. For example, during the Republic of China, soda ash manufacturing, the so-called industrial basic manufacturing technology, was firmly held in the hands of a few foreign companies, and several chemists devoted their lives to research-the so-called research was that the industrial method was produced in the laboratory, and college students could master it at will.
Jiang Huang listened quietly and did not express his opinions easily.
Now the Jinzhou team is normal, and the Gehagen team has some differences, because the Gehagen Institute of Theoretical Physics studied physics and focused on the new thing of quantum physics.
However, the research direction of the great Xia Xing warlocks is different, and the discussion is naturally different. In the past, everyone would still limit the mathematical aspects, but with the encouragement of Cheng Jinzhou, chemical machinery has now become the main discussion.
There is no way. If you want to study something independently when science is not developing greatly, Jinzhou is willing to let the discussion be free.
Insist on discussing that everyone can join and leave a discussion group at any time. This way seems to be more conducive to bringing the talents of astrologers into play.
There are often magicians who study mathematical stars and say that there are some things in machinery, and the latter will also help the former.
Jiang Huang adjusted a good position for himself and beckoned the astrologer apprentice to pass himself a cup of tea and then slowly sipped it.
After Cheng Jinzhou entered the arena, he sat next to Jiang Huang’s star warlock and asked him. After that, he took out his pen and recorded that it was not only Mr. Yisu’s request but also the actual demand, so as to ensure his influence among the star warlocks.
Great Xiali may be able to maintain officialdom and the army, but not the warlock.
After listening for a while, Jiang Huang suddenly asked Cheng Jinzhou, "What do you think of their discussion?"
"who?" At first, however, asking questions made Cheng Jinzhou one leng.
"Burning substance" Jiang Huang said it was the chemistry group. He tapped the pen and said, "Xingzhou Astrologers tried to take out phlogiston in the early years, but they didn’t succeed …"
"Do you believe in phlogiston?"
Jiang Huang smiled and said, "I’m not familiar with this aspect. I want to hear your opinion."
"You are really absorbed in calculus." Cheng Jinzhou teased and said, "I don’t believe phlogiston."
"What about the metal calcination experiment?"
Two people said it was a famous mistake. In the early days of chemistry, people thought that fire was a material entity composed of several small and active particles, which could combine with other elements to form compounds and be free. This proved that someone tried to calcine the metal and weigh it accurately, and found that the metal became heavier.
So the saying "metal+phlogiston = ash" is very popular among people.
Now we know that the weight increase of metal calcination is due to the formation of compounds by oxygen in the gas, thus increasing the oxygen content, but in the 17th century, people will believe that it is evidence of phlogiston.
Cheng Jinzhou took part in this debate because there were not many chemists, and at the same time, because overthrowing phlogiston theory is a history that the current conditions do not have, lomonosov can overthrow phlogiston theory mainly by two points-mass conservation and accurate quantitative analysis, which are not within the scope of gentlemen in the 17th century.
Besides, he doesn’t want to stand out.
Seeing that the members are having a heated discussion, Cheng Jinzhou can’t help but shake his head and say, "Heat is the heat caused by exercise, which can cause combustion. Our star array can also prove that phlogiston is not in practice."
"We may not have found it," Jiang Huang leaned back in his chair and smiled. "Didn’t Cao Feng find a smaller creature recently? We will always find a way to see more small creatures. "
Cheng Jinzhou laughed and didn’t answer the accurate certificate. It was a little troublesome. However, Cao Feng and Jin Xi’s experiments were amazing. They had studied the cell composition, such as chlorophyll, and so on, which entered the naming process.
I can think that this is a point line that can get a lot of contributions.
Speaking, elwin climbed up from his mechanical group and urged, "Mr. Cheng, you have to find a way to get more workers. If you wait, I can’t carry out the experiment. We just talked about making a bigger steam engine."
"How big a steam engine? How to solve the material? Want a lot of steel? "
"I can entrust Xiajing Association to help make it," elwin clapped his hands. "I want to make a bigger steam engine, first 2 meters high and then 3 meters high. One day I can make a steam engine as big as a ship and then I can drain rivers and lakes at will to reclaim more farmland …"
We can’t expect the astrologers to have much environmental protection spirit in this era.
But Cheng Jinzhou looked at elwin with excitement and was not infected.
He can really do more if he add Star Alliance.
Jiang Huang used to be a leader and asked faintly, "How are you going to get more workers?"
"Get rid of the miners next to them first, and more than one worker will supplement them."
"Then what? Increase wages? "
Elwin winked and said, "I don’t care if I want workers."
Cheng Jinzhou shook his head and laughed. "Let’s meet the gentlemen in the mine next to the seminar."

De ‘an first discovered coal about six years ago, and then it entered a slow development process.
It is almost impossible to sell coal to other places because the quality of coal is generally poor and the river is not navigable-cheap coal can hardly be returned.
