Chapter 826 The Key to a New World
Luo Chong rarely comes to the research institute, so this meal really becomes a treat for them. There is no way to not treat them. The canteen on the lake island prepares a fixed amount of food every day. Although the Han tribe is not short of food, the people have come from the time when they were hungry during the tribal period, so they have not lost their thrifty nature.
They usually cook as much as they eat. Luo Chong and his friends suddenly came here, and the canteen was not prepared at all, so they had to ask the chef to cook it now. Fortunately, there is no shortage of ingredients here, and the island also raises chickens, ducks, rabbits and other things. A table of food was delivered quickly, but it was a pity that there were no decent vegetables. In the era without vegetable greenhouses, it was really a luxury to want to eat fresh vegetables in the winter in the north.
The leaders of several research groups sat at the same table with Luo Chong, Qubing was also next to Luo Chong, and on his other side was Ao Fei. The two have become good friends because they designed the camera together. While waiting for the chef to serve the dishes, a group of people started chatting.
"Chief, I have made a new discovery recently, but I don't know if it is worth studying. If it is, which direction should it develop in the future? Can you give me some comments?"
Ao Fei said as he took out a photo transferred from albumen paper from his arms. The image on it was very strange. It showed an aperture, and then there was a shadow that seemed to be moving inside. It was hard to tell what it was, but it was certain that the shadow in the middle could also be transparent, because the center of the shadow was lighter in color.
To be honest, black and white photos can only capture the outline of something, and it is impossible to expect a high resolution.
"What is this photo?" Luo Chong looked at the photo for a while, but couldn't figure it out. Qu Bing took the photo when he saw this, but he couldn't tell what it was.
"To reply, Chief, this is a drop of water that fell from a tree onto the lens when I was experimenting with a new lens outdoors. I have seen this drop of water, and it is absolutely transparent, at least it looks transparent to the naked eye. However, this photo taken through the lens shows that there is a moving shadow inside the water drop, but there is really nothing to look at with the naked eye. What do you think is in the water?" Ao Fei explained after hearing Luo Chong's question.
"You said that this aperture is the water drop, and the shadow inside is the moving thing? And it is not visible to the naked eye?" Qu Bing asked in surprise on the spot with the photo in his hand.
"That's right, that's right, brother Qu Bing, do you have any insights?" Ao Fei asked by the way when he saw that Qu Bing was interested.
"What insights can I have? I can't see it with the naked eye, but I can take a photo with a camera. What does this mean?
Chief must understand. Chief, can you analyze it for us?" Qu Bing had already entered the research state at this time.
It happened that the cook from the cafeteria just brought a dish, and Luo Chong picked up the chopsticks and ate while talking.
"What can this be? From a scientific point of view, your lens is nothing more than a magnifying glass. It cannot be seen by the naked eye, but you can see it through the lens, which means that this thing is extremely small and cannot be seen by our eyes. We can only see its existence by continuously magnifying it.
And you just said that this thing can move, so I judge that it should be a living thing. Look at this photo again. The blurred track behind the shadow above seems to be swimming in the water droplets.
So we can draw a conclusion that you saw a microorganism that cannot be detected by the naked eye but can swim in the water droplets through a magnifying glass. Let's call it a microorganism."
"Microorganism?!" Everyone at the table was shocked and murmured the awkward term just coined by the leader.
"What the leader means is that there are microorganisms in the world that we cannot see and live in the same world with us? Then are they good things or bad things?" Wen Nong from the chemistry group next to him took the lead in raising an objective question.
This is how research should be done, constantly raising questions, hypothesizing problems, and then demonstrating through rigorous experiments, and finally drawing universal conclusions. This is the process of scientific research, so raising questions is the first priority.
Luo Chong nodded. Of course he knew the existence of microorganisms, but he couldn't say it directly. Instead, he had to guide these people to study it themselves and turn it into a specialized science, so he just listened to him.
"Whether microorganisms exist or not is just an assumption I made just now. Isn't there a photo taken by Ao Fei? If we don't use the hypothesis of microorganisms to explain it, then what do you say it is? So we can't make a correct argument now, we are just analyzing assumptions.
Assuming that what Ao Fei took was a photo of a microorganism, and microorganisms really exist, then we should not rush to draw conclusions, and we can't use narrow emotional thinking such as good or bad to draw conclusions.
Take biology as an example. If there are microorganisms, then there are large organisms. You can understand them as living things that we can see with the naked eye, birds and beasts, flowers, birds, fish, insects, and trees and crops. Anything that can grow naturally and can be observed by the naked eye can be included in the category of organisms, but can you tell whether an organism is good or bad? No!
The word good or bad should not appear in scientific arguments, but it should be said whether it is useful to us. Everything has two sides. Our scientific research is a process of finding the truth, and our results are to use the technology we have researched to make various materials usable. Who can say that microorganisms are useless to us?"
As Luo Chong spoke, everyone nodded. Bold assumptions and rigorous argumentation were the scientific concepts that the leader had repeatedly instilled in them. Now they had penetrated into everyone's minds. This time was no exception. Only by looking at the problem from a rational perspective could scientific research avoid going astray.
Ao Fei had been eating and listening silently. When Luo Chong came to this hypothetical conclusion, he asked again.
"Then, Chief, do you think this is worth studying? If we want to study it, which direction should we explore?"
Luo Chong took another bite of food and said, "Of course it is valuable, and it is of great value. Assuming that there are really microorganisms in this world, what does that represent? It means that it is a new world that we have never seen before, and its significance is very significant.
If we can open up this world and go deeper into this world, there will definitely be huge rewards.
Let's take biology as an example. Take the food on the table. Grain is a plant that can grow, which is also a kind of biology. If we master its planting method, we can let our people have enough food and no longer go hungry.
The chickens, ducks, etc. Birds, if we understand their habits, we can breed them in large numbers to provide us with meat and a large number of eggs.
Even this table, isn't it a piece of furniture made of wood?
So many organisms can be used by us to improve our quality of life. Think about it, if we can see the world of microorganisms and let these microorganisms be used by us, what kind of changes can we bring to our lives?
So this research is valuable, and it is of great value.
Here we can raise several questions based on the characteristics of organisms, which is our research direction.
How many types of microorganisms are there? What do they look like? How do they grow and move? How do they reproduce? What impact do they have on our common destiny? What influence does the environment in which it grows have? What role does it play in the influence? What function does it play? These are all our research directions.
In order to study these, a prerequisite must be met, that is, how can we see microorganisms? This is what you, Ao Fei, have to do.
We just defined microorganisms as extremely small organisms that cannot be observed with the naked eye and can only be seen with a magnifying glass. So what you need to do is to make an ultra-high magnification magnifying glass that allows us to see microorganisms through this magnifying glass. It must be able to magnify the size of microorganisms by thousands or tens of thousands of times. In short, make it as big as possible.
For convenience and It can be distinguished from ordinary magnifying glasses, and it also shows its uniqueness and specialization, so here we will give it a special name, which is called a microscope, a magnifying glass that can show microorganisms, or a microscope for short.
The microscope is the key to open the treasure house of the microbial world for us humans, and its significance is also very important. If your color camera has not made any progress, you can study in this direction at present. "
The group of people at the table were dumbfounded. They didn't expect that this casual discovery would be so valued by the leader, but when it came to the last microscope, everyone couldn't help but feel a tingling scalp. Good guy, he said that he wanted to magnify the object thousands or tens of thousands of times, and what level is the current lens technology of the Han tribe?
The magnification of the commonly used monocular telescope is only ten to forty times, and the largest astronomical telescope can only magnify six hundred times. Luo Chong's mouth is thousands or tens of thousands of times, so let's calculate it according to the smallest thousand times, and then we have to double the magnification of the current most awesome astronomical telescope.
Looking at Ao Fei's wide-mouthed and sad face, Luo Chong smiled and patted him on the shoulder to comfort him.
"Don't be afraid of how difficult it is. In fact, the technology of this microscope and telescope is not much different. It's just that one is used for viewing the scenery, and the other is for observing tiny organisms. Let me give you a hint. Microorganisms must be very small, so there is no need to run around with a microscope. Just like the photo you took before, it may exist in a drop of water.
So you need a base and a bracket, and then install a stage, condenser, reflector, etc. on it to provide light for observation, and finally put a super-powered telescope aimed at the stage on it, and that's it.
And the size of this microscope must not be made too big, which should not be a problem, because you should understand that the magnification of a telescope has nothing to do with the diameter, but is achieved by the combination of focal length and lens. Just go for it, I believe in you.
You can definitely make this key to open a new world for us."
