Tong Qian goes to check it out every day. She saw the moldy situation two days ago. Song Yang took a look and found that the degree of moldyness was not high enough.
So I waited another two days and the requirements were basically met.
Song Yang changed his clothes and entered the laboratory carefully.
He was covered tightly and wore a mask, and his hands were also made of fine deerskin gloves.
The tweezers and knife in hand gently remove the mold on the test object.
"I hope it will succeed! It must succeed!"
Song Yang applied the mold to the petri dish very carefully.
After spitting the foam evenly, pick up the petri dish and observe it carefully in the sun.
Make sure it is even before adding the culture medium.
Put the lid back on and carefully place the petri dish on the shelf.
Finally, Song Yang returned to his desk and recorded all today's operation steps in detail.
The culture medium used today is made from two raw materials: wheat starch and taro starch.
Encyclopedia records mention cornstarch.
There is no corn, potatoes or sweet potatoes in Daqian, and there is no easy-to-find starch material here in Jiangzhou.
Song Yang could only experiment with a solution made from wheat and taro starch.
A total of ten petri dishes were made from the two starch culture solutions, but the number of Penicillium was a bit small, and only five petri dishes were spread.
Three wheat starches, two taro starches.
I looked at the experiment records and found that there were no errors or omissions. I signed the date and signature at the bottom.
Experiment date: May 25th.
Experimenter: Song Yang.
After taking notes and putting the notebook away, Song Yang got up and went out.
After changing clothes in the locker room, time once again took care of the rest.
"Ha~"
Song Yang yawned and stretched his muscles in the midday sun.
In fact, the process of cultivating Penicillium just now took less than an hour.
It's just that Song Yang is highly concentrated and is afraid that something will go wrong in the process.
"Your Majesty, would you like some water?" Shen Xiaowan brought a glass of water.
"Well. I'm really thirsty." Song Yang took the water glass and drank it directly.
"I didn't expect that conducting experiments would be easier than working!" Song Yang twisted his neck and laughed.
"I don't understand this. I just hope that the prince can take care of himself." Shen Xiaowan said with concern.
"It's okay, it's okay. I am in good health and can hold on." Song Yang smiled.
After saying that, he even pulled Shen Xiaowan for a kiss.
"Ahem!"
Shen Xiaowan was pulled into Song Yang's arms and heard a cough from behind.
It turned out that Tong Qian was here.
"Hey, it turns out that the prince is making out with Sister Xiaowan, so I'll leave first!" Tong Qian said mischievously, and then turned around and ran away.
Shen Xiaowan blushed, broke away from Song Yang's arms and ran after Tong Qian.
Looking at the two girls making love, Song Yang smiled.
"A happy life is as beautiful as a picture!"
Song Yang stretched again and left the small courtyard.
After leaving the door, Song Yang went straight to the glass workshop.
Gongsun Mo is leading the workers to process glass windows.
Fang Zhe and Yu Ming have both seen Song Yang's laboratory glass window, and they all like it.
They all begged Gongsun Mo to get them some pieces of glass.
The glass workshop has completed the production of glassware, and there are no production requirements for the time being.
Gongsun Mo agreed with Fang Zhe and the others, who had been burning glass windows recently.
And the output is getting bigger and bigger, and it has been put into supply and marketing cooperatives to sell.
"Your Majesty, you are here. What do you have to do today?" Gongsun Mo ran over with a smile.
The job of making glass is more profitable than that of carpentry. One piece of wood work can be exchanged for several kilograms of grain, and one piece of glass can equal several pieces of wood work.
So this old man is in a good mood recently, and everyone is smiling.
"Do you still have the previously produced telescope lenses?" Song Yang asked about this.
If you want to do experiments, a microscope is indispensable.
Song Yang had forgotten about this thing before. When he was working on the petri dish today, he suddenly realized that he was still observing the petri dish with the naked eye...
So he came to Gongsun Mo to ask for lenses.
"There are some, there are still more than twenty pieces left."
When Gongsun Mo heard that Song Yang wanted lens lenses, he nodded hurriedly.
Soon Gongsun Mo brought over a box of lenses, all of which were worn lenses.
It was originally intended to be a single-channel telescope, but two batches were produced before, totaling 80 pieces.
These are enough, and the remaining lenses are temporarily stored.
Song Yang picked a few of suitable sizes and asked Gongsun Mo to find some small wooden strips for him.
Under Song Yang's guidance, Gongsun Mo built a wooden frame for him on the spot.
After installing the lens, Song Yang took a look and found that the effect was very unsatisfactory.
Lenses used for monocular telescopes are still somewhat unsuitable for use on microscopes.
Song Yang picked a few of suitable sizes and started polishing them with tools.
This grinding lasted all afternoon, and I even ground a few pieces in the process...
Holding the polished lens piece, Song Yang measured it and found that the size was just right and the light arc transparency of the mirror was sufficient.
"Hold the lamp."
Song Yang said hello, and Gongsun Mo immediately asked someone to bring the candlestick over.
It was almost dusk at this time, and the light was a bit poor, so candles were needed to make up the light.
Song Yang installed the lens on the wooden frame, then used candlelight to test the simple microscope with the wooden frame.
Song Yang's original version of the microscope is definitely not as good as a serious optical microscope.
But this is the first version, and there is still a lot of room for improvement in the future.
This is much better than the super simple one just now.
"Old Mo, come and take a look, one eye is facing here and looking down."
Song Yang made room, pointed at the microscope and said to Gongsun Mo.
After that, I compared the usage.
Gongsun Mo imitated Song Yang's behavior just now, squinting and looking into the lens tube.
The experimental object on the stage was a piece of Song Yang's hair, and Gongsun Mo could clearly see the hair through the microscope.
"Your Majesty, this thing can be seen more clearly than a telescope." Gongsun Mo nodded and got it.
"This is far from what I want." Song Yang shook his head and said.
"Old Mo, you have produced so many telescopes. You should know that through the combination of lenses, you can magnify the observed objects to see more clearly."
Song Yang took Gongsun Mo and sat next to the original microscope and said.
"Yeah, the common people understand this." Gongsun Mo nodded and responded.
"My requirements for this equipment should be clearer and the magnification effect should be better. Not only hair, but also dust and even smaller things can be seen clearly."
Song Yang pointed at the microscope and said.
"Smaller things?" Gongsun Mo didn't quite understand.
"Yes, things in the world are made up of many smaller things. The knowledge here is relatively complicated and will be discussed in class later." Song Yang explained.
"Oh. So what does the prince need from the common people?" Gongsun Mo asked in confusion.
"Now I hope you can continue your research on the microscope. I will draw you some lens combinations. You have to experiment one by one to find the best combination. In the end, you must magnify a hair at least fifty times!"
Song Yang looked at Gongsun Mo and said.
"Fifty times? Just adjust the lens combination to magnify the hair fifty times?" Gongsun Mo said with a surprised look on his face.
Now this first-generation product can grow hair up to five times.
Song Yang asked for fifty times!
"As long as we find the right combination and angle, we can definitely do it." Song Yang said solemnly.
"Okay! Leave this matter to the common people, who will help the prince try it out one by one!" Gongsun Mo said solemnly as he looked at the microscope.
"Old Mo, it's actually not that difficult. There aren't many combinations in total."
"And I have also drawn some basic styles for you. You just need to try them one by one."
Seeing the serious look on his face, Song Yang smiled and patted Gongsun Mo on the shoulder.
Gongsun Mo's old face wrinkled and he laughed.
Song Yang himself doesn't have time to do research and development here, so he can only leave these tasks to those who are capable.
This is true for guns, artillery, and steam engines.
When it comes to practical ability, Song Yang feels that he is not as good as the craftsmen. All he can provide is some theoretical knowledge and a generally correct direction.
The specific operations have to be done by the craftsmen.
"Let's go, it's getting late. Let's get off work today. We'll think about this tomorrow." Song Yang pulled Gongsun Mo and said.
"Yeah. I'll tell them to get off work now. I have to go back early tonight. The brat said he has something to tell me." Gongsun Mo nodded.
The brat he was talking about was his son Gongsun Qi.
"Well, let's go. I, the king, will take the first step."
Song Yang didn't care what happened to his family, he said hello to Gongsun Mo and turned around and left.
Gongsun Mo returned home, and his son Gongsun Qi and his daughter-in-law Bai Xiaohua had arranged a table of delicious dishes.
"What day is it? Why did you prepare four dishes and one soup?"
After all, there is some shortage of supplies now, so we only have two people cooking on weekdays.
Today is not just a New Year holiday, it has actually doubled.
"That..." Gongsun Qi scratched his head and didn't know where to start.
"What's wrong! Did you get into trouble?" Gongsun Mo's face darkened, he blew his beard and asked with eyes wide open.
He thought his son had gotten into trouble, and he was holding a drink with him to make amends.
"No, no, my husband didn't cause any trouble." Bai Xiaohua hurriedly explained to Gongsun Qi.
Although Gongsun Qi is ruthless and doesn't talk much, he is very afraid of his father. He doesn't dare to speak even if Gongsun Mo looks at him.
"Xiaohua, what's going on?" Gongsun Mo rolled his eyes at his son and then looked at his daughter-in-law.
"That...I..."
Bai Xiaohua was about to speak when her expression suddenly changed, she covered her mouth and ran out.
"Ugh~"
Soon there was the sound of vomiting outside the door.
Gongsun Mo's face lit up with joy, he pulled his son and asked in a low voice: "Yes?"
"Yeah." Gongsun Qi nodded.
"How long?"
"A month and a half."
In fact, it happened after Gongsun Qi and Fang Zhe came back.
I checked with Li Rui today and found that his pulse was normal.
"Hehe. Okay, okay! It's time to celebrate!" Gongsun Mo smiled and took a bite of food.
After chewing a few mouthfuls, he turned to look at Gongsun Qi and cursed: "You bastard! What's so weird about this! Humph!"
He cursed and started eating happily. There was no wine, so he could only drink some herbal tea to moisten his throat.
But this did not affect the old man's mood. The teacup made a sizzling sound, as if there was really wine.
