Chapter 64 The principal is going to teach people to make money again

If you ask a magician, what is the purpose of learning magic, more than [-]% of them answer is to make money, and the rest answer is to make a lot of money to explore the road of magic. Those who use love to do magic are not short of money at home. Local tycoon.

In the past, magicians had limited means of making money. They either relied on force to become a part of the landlord class, or they made unknown things and sold them to local tyrants, or they made money from their peers.

Now in Wesson, everyone has a new choice: they can earn ordinary people's money.

Now people in Wessenburg University have a consensus that despite the young age of the principal, he is a genius in making money with magic.

Vice-principal Manuai has studied necromancy for so many years, but he didn't make much money before.

Under the instruction of the principal, he switched to specialize in the field of long-term food preservation. He has achieved some results so far. As long as he solves the problem of why some soups in the dehydrated and sealed condensed soup will change their taste after a long time and others will not. It's raining gold coins.

And that guy from BASF, not long ago was still worrying about raising money to get married, relying on the headmaster's advice, now the money he earns to marry several wives depends on his waist.

Now the principal said that he had a new idea, and a group of people immediately became excited.

Frederick noticed that the eyes of these people were green, like a hungry wolf looking at a lamb.

"Ahem..." He coughed twice, "Let me ask, is there anyone who can expel the air in a thing to form a vacuum?"

At this time, a big sister suddenly shouted: "My fiancé is the best at this! Principal, you wait, I'll find him right away!"

Frederick blinked, and the big sister had already run to the blacksmith's stable and pulled the horse out to find someone.

The others sighed together, as if seeing a golden mountain leaving them.

"Okay, let's talk about other things first." Frederick shrugged, "Let me talk about another kind of thermometer."

"Everyone knows about thermal expansion and cold contraction, and we also know that different metals deform differently under the same temperature change."

"We can stick these two metal sheets tightly together. When they deform due to temperature changes, one side deforms more and the other deforms less, then it will bend."

"We can use this bending deformation to detect temperature. We don't have to worry about the failure of boiling like water. It can measure very hot things, as long as they don't burn red."

What he was talking about was the principle of a bimetallic thermometer, which is not difficult to say, mainly due to technical issues, and a small amount can be rubbed out by hand, which is enough for now.

Everyone, you look at me, I look at you, and then nod one after another.

Frederick was ready and gestured to Karpo, and the head maid immediately took out a piece of parchment with a number on the corner of the shoulder bag.

He handed the parchment to Ogilvy, and several people crowded over to read it immediately.

Ogilvy simply went over and put the parchment on a table, and everyone gathered around the table to study it.

These scholars who study golem puppets all have metallurgy and processing skills, and they can see the principle of this mushroom-like bimetal thermometer at a glance.

The core of the thermometer is a long, spiral-shaped heat-conducting sensor made of two metal sheets. When the temperature changes, the top will rotate to drive the pointer.

Everyone looked at it for a while, and a student said: "Principal, if this metal spiral is made flat, it can be made as big as a palm. It can be placed in the room to measure the temperature. If it is made smaller, it can be put in a pocket. What do you think?" Yes or no?"

No one answered after a while, and only then did they realize that Frederick had been pushed outside by them.

Everyone squeezed awkwardly to make room.

After Frederick passed by, he said, "If you think it's possible, you can try it."

The student immediately said excitedly: "Okay, I did this!"

There is still a big market for thermometers, not to mention the rich and the rich, at least well-off.

Then someone poured cold water: "What temperature scale are you going to use?"

The student frowned in distress, obviously this was not the first time he had encountered this problem.

Frederick said: "It's okay, we use our own temperature scale."

At this moment, there was a sound of hoofbeats, and then a shout.

"Here we come! Principal, people are here!!"

Just now, the big sister dragged a pretty boy and ran in hastily.

That handsome boy also had a look of excitement, as soon as he entered the blacksmith shop, he immediately greeted the principal and introduced himself.

"Duval?" Frederick raised his brows, "I remember that there was a big man with this surname in Angland before."

Duval replied politely: "I'm just an offshoot of the family. I only have a knighthood and a manor. I don't want to farm for the rest of my life. I never went back after I went out to study at the age of 12."

Frederick said "Oh" and said, "It's quite profitable to sell wool over there."

Duval replied sincerely: "Who dares to say that he will make money in front of the principal."

Frederick just smiled and asked, "Where were you just now, why did you come so fast?"

Duval replied: "I'm at BASF, and I'm studying the pressure cooker invented by the principal. I found out that there is a relationship between the boiling point of water and the air pressure. Today, I'm trying to see if water can boil at a lower temperature under low pressure."

Frederick said: "Of course, if you don't believe me, if you go to the top of a high mountain, the water will boil and the meat will not be cooked well."

"By the way, you can control the air pressure?"

Duval didn't think about the boiling point, making money is the most important thing, and immediately replied: "Yes, I am good at wind magic, I can create a vacuum to kill enemies, and I can also create high pressure to cause some troubles for people."

The corner of Frederick's mouth twitched, and he said, "Who can stand up to you on the battlefield."

Duval shook his head and said: "I don't like killing, and there are many ways to break this method, and it will be useless if the wind is strong."

Frederick nodded and said, "Then use this magic to make money."

Duval immediately stood at attention and replied loudly: "Thank you, principal, for your cultivation!"

Frederick touched his hair, asked Karpo to bring another piece of parchment, put it on the table and said, "Let's talk about the thermometer from the beginning."

"To make a thermometer, you must first confirm the temperature scale. Zero degrees is set at the freezing point of water, which is very common. 100 degrees is set at the boiling point of water at a pressure of 760 millimeters of mercury."

After he finished speaking, someone asked: "Why are you so sure?"

Duval answered first: "The boiling point of water is related to the air pressure. That's for sure. Under a certain air pressure, the boiling point of water remains unchanged. It is reasonable to use it to determine 100 degrees."

"The air pressure of 760 millimeters of mercury column is neither big nor small, similar to the air pressure at the seaside, within the fluctuation of up and down, it is just rounded up."

His explanation sounds reasonable, and there are no objections.

The student who said he was going to make a bimetallic thermometer just now said: "Well, let's make a thermometer according to this temperature scale, let's call it Wesendu."

Everyone nodded in agreement.

It doesn't matter to Frederick, this one is not bad.

He put another piece of parchment on the table, and said, "I just talked about the bimetallic thermometer, now let's talk about the liquid thermometer."

"The liquid thermometer works the same as those existing thermometers, but it has a vacuum inside, which eliminates the error caused by air pressure."

Duval said: "I can use the magic circle to create a vacuum area, and the sealing operation inside can ask Professor Ogilvy to design a special golem puppet arm."

Ogilvy said: "This is simple, Wagner can do it, you can discuss it with her."

Duvall's fiancée smiled smugly.

Frederick continued: "Our own glass workshop will only start construction next year, so there is no rush."

"But now you can make a new thing to make money."

Another parchment appeared on the table.

"Temperature is transmitted by objects, and vacuum can effectively insulate temperature transmission." He pointed to the cross-section of the thermos cup on the parchment and said, "You can make this kind of cup and kettle first. There is a vacuum between the two metal shells. Just leave a small tail and heat and seal it in a vacuum environment."

"You can figure out a way for the lid, it's almost enough."

Duval's eyes lit up, this thing is good, it's very cold now, if there is such a cup with hot water, it will definitely keep it warm for a long time.

Frederick finally said: "My ultimate goal is a thermometer and a vacuum-insulated container. You all practice your hands first, and earn some money to improve your life. When the technology is sufficient, I need your products to make equipment for an experiment."

"If this experiment achieves my desired goal, your names can also appear in textbooks."
