Chapter 469 The ultimate goal.
Qi channels and acupoints have always been controversial in the medical community.
Ye Kun didn't dare to make any comments casually.
Because you don’t understand the traditional medical theories of China, if you are not careful, you will be slapped in the face.
So, Ye Kun said:
"To do scientific research, we must have a spirit of exploration. Whether meridians and acupuncture points exist and whether they can be directly visible requires everyone to continue researching and exploring. One day, there will be a conclusion."
He Tiantian thought for a moment, and suddenly asked, "Master Ye, what is the end of science and technology? What is the ultimate goal of studying science and technology? Is it really for the benefit of mankind?"
“That’s a very good question.”
Ye Kun looked at everyone and said slowly: "Let me first talk about the fact that technology has benefited mankind. Indeed, technology has benefited mankind, but technology has also brought disasters to mankind. For example, we have made swords, bows and arrows, guns, and gasoline incendiary bombs, which have made human death faster and easier.
If ancient people fought, there wouldn't be many casualties. But now, when people fight, a lot of people die. In the future, humans will develop more powerful bombs. One bomb can destroy a country and tens of millions of people.
Perhaps one day, humans will perish, destroyed by the weapons they have created. This is the tragedy of humanity and the tragedy of technological development.”
In later generations, there is a weapon called a nuclear bomb that can easily wipe out all of humanity.
Looking further ahead, there may be some antimatter weapons that can destroy even the earth in an instant.
Ye Kun couldn't explain those high-tech weapons, but he pointed out the development trend that the weapons were becoming more and more advanced, more and more powerful, and more and more dangerous to humans.
Jin Feng asked: "Is there any way to avoid this situation?"
"No, unless we can ensure that high technology will always be in the hands of civilized people. Of course, this is a matter for the future. Current weapons are not yet capable of wiping out all of humanity."
Ye Kun smiled and said, “Let me explain what He Tiantian said, what is the ultimate direction and purpose of scientific research.
The ultimate goal of scientific research is to find a unified theory that can accurately describe everything in the universe!
In other words, the end of science is to understand every detail of everything in the universe, accurately describe it, and accurately predict its future. "
The above words were said by Hawking.
The scientific community all agrees.
He Tiantian thought for a moment and asked:
"Isn't it like this... When our scientific research reaches its end, we will know what the earth will be like in 10,000 years, and what the universe will be like in 100 million years?"
"Right, that is it."
Ye Kun held up the teacup in front of him and said, "When scientific research reaches its end, we will know when and under what conditions this teacup will be decomposed and turned back into soil."
These theoretical viewpoints are somewhat profound.
Many people didn't understand and just stared.
He Tiantian smiled and said, “The Daqin scientists in the small town of Rome may be interested in what Lord Ye said.”
Sun Yi asked: "Brother, which one do you think is better, the Romans or the Chinese?"
“They are all amazing.”
Ye Kun smiled and said, "There are four ancient civilizations on this earth, Rome and China are both among them. If you ask me, the science and technology of ancient Rome may be better than ours.
Because in our country of China, apart from the Mohists, no one advocates science. Everyone is busy selecting filial and honest people to be officials and writing articles to flatter the court. "
Everyone laughed.
"Don't laugh, what I said is true." Ye Kun couldn't help but smile and said:
"Last month, there was a sour scholar who wrote an article praising me for my handsomeness, my appearance as good as Pan An, my appearance as good as a dragon and a phoenix, and my appearance as good as a god. When I asked him about it, I found out that he had never met me before, but he wrote such a detailed article. This is just flattery. If he had the time, he could study the principle of drilling wood to make fire, which would be better than writing such a crap article."
He Tiantian couldn't help laughing: "Master Ye, what they said is right, you really have the appearance of a heavenly man, a dragon and a phoenix."
"Come on, forget it. I was like a madman when I was doing scientific research in seclusion last time. You guys have seen it before."
Ye Kun waved his hand and continued the tea party.
The next day, Ye Kun took He Tiantian and others, as well as masters from the Ministry of Chemical Industry, to do some experiments.
Electricity is passed through water to separate hydrogen and oxygen.
This is an experimental class in junior high school, it’s very simple.
Ye Kun first wrote down the molecular formula of water, and then explained to everyone the concepts of hydrogen and oxygen, and the principles of producing oxygen and hydrogen.
Sun Yi asked: "After this oxygen is extracted, can we see it?"
"It is colorless and tasteless, invisible, but I will let you see it."
Ye Kun smiled and started to operate.
After a long wait, hydrogen and oxygen were separated.
Hydrogen in a paper cup.
Ye Kun struck a match and moved closer.
boom!
With a loud bang, the paper cup exploded.
Everyone was shocked.
Ye Kun smiled and said, "I just said that hydrogen can burn and explode under proper sealing conditions. This is the combustion and explosion of hydrogen. Now, let's take a look at the combustion-supporting effect of oxygen."
All the scientific giants in Dading Kingdom looked at Ye Kun with wide eyes.
Ye Kun took out a red-hot wire and said:
"Masters in steel mills all know that to melt iron, extremely high temperatures are required. But what everyone doesn't know is that iron can also burn like wood. Now, I will put this iron wire in a glass bottle of oxygen, and it will burn..."
Oxygen, in a glass bottle.
In full view of everyone, the red-hot iron wire was inserted into the bottle, and immediately beautiful flames like fireworks emerged.
After the flames went out, only half of the wire was left in Ye Kun's hand.
There were a few bits of burnt wire debris in the glass bottle.
A simple junior high school experiment left everyone dumbfounded.
Ye Kun smiled and said:
"My mission this time is to produce oxygen on a large scale and store it, upgrade the steelmaking industry again, and create qualified high-strength drill bits and various lathe blades. With high-strength drill bits, our lathes can be considered barely qualified."
Until now, the hydraulic lathe that Ye Kun used was not considered a real lathe.
One is that the power and speed are not enough;
One is that the vehicle parts are not strong enough.
Now, this problem can finally be solved.
With precision lathes, precision ball bearings can be made and more precision machines can be produced, including components for steam engines.
He Tiantian smiled and said:
"Master Ye, you used to say that industrial technology is a complete system that requires the cooperation of various disciplines and common progress. Now, I finally understand. Metallurgy, electricity, chemical industry, petroleum... all projects must be developed to promote the overall progress of the industry."
Ye Kun nodded and said, "Tiantian is still the smartest one, and also the most proud disciple I have brought up. You are the most suitable person to be the dean of Tai College and Doctoral College in the future."
Among the scientific researchers, He Tiantian has the best theoretical knowledge and the best practical application.
He Tiantian was deeply influenced by Ye Kun and completely accepted the scientific and technological views of later generations. He based everything on reality and sought the perfect combination of theory and practice.
