A Man of Science and Engineering in Troubled Times Wandering in the Late Qing Dynasty

Chapter 73
The rector of the University of Paris, Greer, couldn't help but said: "I heard that the president of the Royal Society said that Li Yu is a person who can bring surprises at any time. Today's meeting was extraordinary. This speech can be regarded as one of the most successful speeches of the year! "

Li Yu actually thought more in his mind:

Since the Middle Ages, science and theology have been fighting for hundreds of years. In the past, theology has always been superior and has the absolute right to speak. Even the earliest universities were basically church universities.

It can be seen from some of the names that have been handed down to this day: such as the famous Trinity College of Cambridge University.What is the "Trinity"? Isn't it the Trinity in the doctrine, that is, the Father, the Son and the Holy Spirit are combined into one.

In the past, theology relied on your undeniable wrong theories to control the thinking of the whole of Europe, and even sold jaw-dropping "indulgence notes": once the coin rings, your sins will be eliminated.

But can you prove this wrong?

you can not!
If you are still suffering, the church will say that you are not sincere enough and you need to pay more!

Many theological theories have no falsifiability at all, and they were very confusing to people in the Middle Ages, because the people at the bottom could indeed see that very few people gave a lot of money, and then became rich and prosperous.Then the church desperately publicized such one or two successful special cases, saying that this is correct, and everyone should hurry up and buy indulgences!

Then the church held up the sickle, and easily harvested the green leeks that have been growing for thousands of years!
Do you find it ridiculous?

Not at all ridiculous!In the 21st century, countless people will fall for this kind of scam.

So when you look at any deceptive statement and want to distinguish right from wrong, you only need to think about whether it can be proven wrong, and you can avoid a lot of detours.

Don't listen to some success masters trying to promote brainwashing with one or two successful cases. Such statements are very dangerous!Because you failed, he only needs one sentence to beat you to death: the success is due to me, and the failure can only be because you did not do enough.As for what is enough, it is metaphysics, and there is no standard at all.

Since the extinction of ancient Greece, theology has ruled mankind for thousands of years, and during the thousands of years of being suppressed, science has been gathering strength in dark corners.

It was not until the Renaissance period that the spark left by ancient Greece thousands of years ago was finally found in the ashes that had been burned.

So science, also began to revive.

But the fire was burning hard, and it was poured down by buckets of theology from time to time.

To this day, although science has conquered the city and even defeated theology completely, there are still many people who are superstitious and ignorant.

You can't say they are stupid, you can only say they are lazy!Lazy to study, just want to understand the world through simple theological explanations, and seek self-comfort.

Regarding science, the most ridiculous sentence I have ever heard is: the end of science is theology.

I wondered, what is this not farting?
If you say that the end of science is philosophy, it still has some meaning.

Oh, for a long time, the credit for thousands of years of science was snatched away by theology in one sentence?

This is simply six times better than Yuan Shikai!At the very least, Lao Yuan has real strength in his hands and can mobilize the entire Beiyang Army.

Science and theology began in the Renaissance, and the struggle between the two remained deadlocked until the beginning of the twentieth century.

The so-called spreading rumors is one mouthful, but dispelling rumors is a waste of time.

Science has always been on the broad road, dignified and upright; but theology only needs to explain everything with the illusory God, which is simple but extremely confusing.

The theology of the birth of the world can be simply attributed to God creating all things, and even after six hard days of creating the world, you can come to rest for a day, how pleasant!

How do you say this is falsified?

Can you explain it clearly?

Speaking of breaking the sky, people only need one sentence: Can you prove me wrong?Can you prove that God doesn't exist?

Can you?
Of course not!So this is typical unfalsifiability!
Science has exhausted countless efforts to explain the birth of the world. Countless scientists have spent their lives, from gravity to the big bang, from biological evolution to gene sequencing.But in the 21st century, it has not been fully explained, because science is rigorous, and any unknown details will never be prevaricated with a false sentence.

Li Yu really hated any false theories.

His grandma once suffered from a leg problem many years ago, and then a sorceress said that she would treat it, and the fee was not high, and she had already cured several of them.

But she didn't say how many disabled she had treated.

After a lot of tossing, my grandma left permanent feet!
Li Yu really hated how old he was at that time, if it were now, he would definitely break her leg too! NND, I will treat you too!If it can't be cured, then your heart is not sincere enough!
After listening to the speech, Mrs. Curie seemed to have tears in her eyes. She is a person who can dedicate herself to science, and she did fulfill her promise and dedicate herself to science.

Especially four years later, Pierre Curie died in a car accident, and the departure of her soul mate almost broke her.But she soon devoted her life to the study of radiation science, and even had a glimpse of radiation as a targeted treatment for cancer.

But it is a pity that she also died under the radioactivity she discovered.

Madame Curie has a great love for science. Today, someone can finally explain to her what science is, and she is naturally very excited.

She is a woman who grew up amid doubts, and now she finally has a weapon that can deal with doubters.

The physics she is engaged in, and of course biology, are the most likely to be questioned by others, because physics and biology are closely related to everyone's life, everyone can touch it, and many people can just chime in.

As for mathematics and so on, people don't bother to fight at all, because mathematics is very abstract, and it is completely incomprehensible if it is a little advanced.You have seen a few people making up rumors about mathematics, but you don’t understand how to fight with me in mathematics?Needless to say, it is too complicated, you ask God to solve a partial differential equation for me!

But physics and biology are different. There are always some laymen who think they understand it well and insist on giving you a few theoretical sentences.

The best way to deal with it may be to stay away from them.

Li Yu's speech today can be regarded as an introduction in advance.

It's just that the current science has not yet fully developed, but it also happens to witness step by step that science will continue to break through and open up thousands of miles in the future.

Pierre Curie, who was sitting next to Mrs. Curie, even stood up directly: "Wonderful speech! Advanced theory! It is hard to imagine that you have made such achievements in philosophy besides rays, thermodynamics, and astronomy. My Pierre May you be called a science star!"

The principal was also very satisfied. The presentation of this speech would also allow the French newspaper industry to resist the strong momentum of British newspapers in the field of science during this period.

Li Yu had finished speaking, and said, "It's just a family statement. If there are any mistakes, please correct me. I'll go down first."

The principal quickly stopped him: "Wait, it's rare to come here today, so I have to answer some questions from the students."

Li Yu had no choice but to stay on the stage, and the principal said, "If you have any questions, feel free to ask."

Immediately, a lot of hands were raised in the audience, and Li Yu pointed to a man with a straight inch and two mustaches and said, "You can tell."

Mustache stood up and said, "Hello, sir! My name is Paul Langevin, and I am a doctoral student graduating from the University of Paris."

Well!Li Yu came up and set another boss on fire!
So speaking in this kind of university is really not easy, and you may meet future big names casually.

Langevin is a doctoral student of Pierre Curie. Langevin's equation was created by him. He will also be an academician of the French Academy of Sciences in the future, and he has also served as the chairman of the Solvay Conference.In addition, he will have a very powerful student in the future: De Broglie.

Langevin will still have a little scandal with Madame Curie ten years later. It is a pity that in romantic France, the nobles engage in extramarital affairs every day, but Madame Curie, the widow, cannot be tolerated because she is Polish!

Madame Curie had no choice but to stay away from right and wrong, and there was no disturbance with Langevin since then.

——The key is that Madame Curie won another Nobel Prize to stop the gossip.

Hey, even though France welcomed the Curie couple into the French Pantheon, which symbolizes the highest honor in France like Westminster Abbey, in 1995, it is still impossible to forget the doubts Madam Curie received during her lifetime.

Others can make countless mistakes, but as long as she is a little out of line, she will be accused by the French.

It's really hard!
But this is all for later.

Li Yu was most afraid of the boss's question, so he said, "Dr. Langevin, what questions do you have?"

Langevin is now also working on X-rays, uh, rays again!So X-rays were really popular at that time, and a bunch of scholars were studying them.

Langevin asked: "I have read your paper, which is also based on the atom theory. I am curious, how to use experiments to explore the existence of atoms?"

Li Yu said: "Many scientists are already working on this problem, and I heard that the Cavendish Laboratory of the University of Cambridge in the UK pays special attention to research in this area. If possible, you can also build a laboratory in this school."

Langevin really looked forward to the establishment of atomic theory, and his later famous research is also based on this.

"I think I'll definitely keep that advice in mind."

Curie seemed to have something to say, but seeing the enthusiasm of the students behind him, he continued to sit firmly in the chair and continued to watch for a while.

Another student who studied thermodynamics asked: "Excuse me, do you think thermodynamics has developed to the top?"

Li Yu said: "Of course not. Although thermodynamics is relatively complete, its application is still promising."

Thermodynamics is indeed relatively complete at the theoretical level, and scientists have studied it thoroughly for hundreds of years.But if it is completely complete, it has not yet reached that level.As for the application, there will be more in the industry later.

　This chapter is written with a bit of emotion, hey, I have really seen many friends who were deceived, everyone must keep their eyes open! ! !
