Police Detective

If you think about it carefully, Professor Tang is right.

The skin is a layer of defense tissue that isolates external substances, and it is not the stomach. How can it absorb the substances in the mask? At most, it only requires replenishing water, and the time is very short, so you can keep the mask off for a few minutes.

Those very expensive supplements are not only no different from ordinary food when eaten, but may also contain excessive amounts of heavy metals.

Anyone who has studied biology knows the enrichment effect of heavy metals in the food chain, but they still like things like tiger bones and whale meat.

I have studied chemistry and know that diamonds are carbon, and there is no difference between synthetic and natural ones, but I just believe what the advertisement says.

Is this the science we study?

Don’t the undergraduates and graduate students here understand this?

But why do most people still obediently pay the IQ tax?

This is a very serious problem - what you have learned has not yet been attributed to yourself.

Does water that has been boiled multiple times have high nitrite content? Is natural slightly alkaline water good for health? Can a magnetic field turn water in a cup into small molecular clusters for easy absorption?

Believing this is just like many people still superstitiously believe that the sewer system in Qade Bird City was built by a certain country that colonized it in the past. Anyone who uses his brain knows that it is impossible.

However, everyone is used to not using their brains.

During this time, Professor Tang discovered many misinterpretations of science. Some of these misinterpretations stem from the need to attract traffic, while others are simply a lack of scientific thinking.

This is not the biggest problem, but many college students and even Ph.D.s still choose to accept these theories and even become promoters of these theories. This makes Professor Tang feel chilling in his heart.

"Science does not mean that you must maintain unwavering superstition in it, but I hope that what each of us learns anywhere belongs to us." Professor Tang said: "Otherwise, what we learn will be ours." Nothing is your own.”

Professor Tang gave a random example, and the whole classroom started whispering.

Many of the people present believed these things!

It would be fine if we usually chatted and refuted rumors, but now that the professor said this, if you think about it carefully, you really don’t have enough scientific thinking.

This is also the reason why many highly educated people may be defrauded.

Moreover, science also requires logic. Even if some words are correct, they are of little value.

For example, there are many mosquitoes in summer, it is very hot, and there are many people swimming, so many people drown.

"Shocking! According to scientific statistics, where there are more mosquitoes, people are more likely to drown!"

It has to be said that in the process of discussing chemistry and scientific literacy, Professor Tang also instilled in everyone some anti-fraud and ways of thinking to avoid being deceived.

"After talking about these simple chemical principles, I want to talk about one thing next. When our school starts in September in the second half of this year, there will be a new provincial key project about the application of quantum chemistry in lithium-ion secondary batteries. topic. At the end of this year, I may lead a group of postdocs. Students who are willing to do this can pay attention to the school’s official website. Moreover, students who are currently only in the undergraduate or master’s program don’t be discouraged. This project will take a longer time.”

The previous ones are all for the general public. This part is the purpose of many doctoral students coming here!

As we all know, scientific research is an area that only God can touch. On the day when ordinary people graduate, the experiments they do will always repeat the processes of their predecessors, with known results. Scientific research is not the case. It requires a strong heart, constantly breaking conventions, violating common sense, and being able to tolerate failure.

But, this is still the jewel in the crown! This is the process of making something out of nothing, which is the highest expression of human wisdom!

Research on quantum theory is generally done by two types of people. The bosses of the former are pursuing the microscopic world at the Planck time level, while the melon-eating masses of the latter are used to treating this thing as science fiction content.

In some science fiction novels, everything is explained using quantum technology!

It is even said that Fengyi, an unknown author of detective novels, mentioned this thing several times in his detective novels, which is simply crazy!

"I will give a lecture on the next content. Students who can keep up can consider what I said before."

When Professor Tang said this, the girl on Wang Huadong's right finally raised her head and prepared to listen to the lecture.

“Today’s lecture is about computational simulation of physical properties of molecules and condensed matter systems.

"

After Professor Tang said the first sentence, Bai Song understood, and there was no need to listen to the rest.

Then he opened his book and read it carefully.

Half an hour later, Bai Song finally understood what the two or three questions pointed out by the girl were. These were the results of searching online on his mobile phone. It was too difficult.

Hu. Bai Song plans to continue listening to the class for a while.

"Studies of lithium-doped aromatic carbon compounds using the abiniti molecular orbital method."

Let's continue reading.

A class, which can also be said to be a lecture, lasts almost two hours. In the next one-hour class, two-thirds of the people couldn't understand it at all, and only a few dozen people could understand it. Although I couldn't understand the rest of the lecture, it was still very inspiring to hear Professor Tang talk about the application of functional analysis in chemistry.

Of course, there is no doubt that Baisong belongs to the two-thirds.

This is also a star effect. Although they didn’t understand it later, almost no one left.

After the class was over, Bai Song breathed a sigh of relief.

To be honest, his position is called "teaching assistant". He is really afraid that Old Tang will get mad and ask him to give a lecture. Basically, he will become famous once. After all, this course is videotaped, and all courses will be recorded. is saved and posted to the university’s website

Now Bai Song is not afraid of becoming famous. If he becomes more famous, even if he is brought into the sight of some people again, he will be fully prepared.

He was really afraid that these people wouldn't come!

However, although he is not afraid of becoming famous, he also does not want to be embarrassed.

After the class ended, the students applauded one after another.

Professor Tang also relaxed, walked off the podium, and walked to the girl.

"The next open class is next Saturday. I can't come over. You prepare for me." After Professor Tang told the girl, he then looked at Bai Song: "You are also a teaching assistant, and you also prepare for the next class. In the first half of the next class, you Let Jianguo do the talking in the second half."

"What!" Bai Song was still confused! Let him talk about the first half?

He wasn’t good in the first half either! This is just a joke! ! !

Also, what does Jianguo mean?

Is this girl's name Jianguo? ? ?

Bai Song felt that he believed in science again.
