If you think about it, Professor Tang is right.

The skin is a layer of defense tissue that isolates external substances, and it is not the stomach, so how can it be possible to absorb the substances in the mask? At most, it is to replenish water, and the time is very short, and it can keep the mask off for a few minutes.

Those very expensive supplements, when eaten in the stomach, are not only no different from ordinary things, but also may have excessive heavy metals.

If you have studied biology, you know the enrichment effect of the food chain on heavy metals, but you still like things like tiger bones and whale meat.

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

Is this the science we study?

Don't you all know these for undergraduate and graduate students?

But why do the vast majority of people still obediently pay the IQ tax?

This is a very serious problem---- what has been learned, has not yet belonged to itself.

Water that has been boiled many times has a high nitrite content?Natural weakly alkaline water is good for health?Can a magnetic field turn the water in a cup into a small molecule for stool and absorption?

I believe this, just like many people are still superstitious that the sewer system number of Jade Bird City was built by a certain country that colonized it back then, but anyone who uses his brain knows that it is impossible.

However, everyone is used to not using their brains.

During this time, Professor Tang has discovered many, many misinterpretations of science. Some of these misinterpretations stem from the need to attract traffic, and some are really without scientific thinking.

This is not the biggest problem, but many college students and even PhDs still choose to accept these theories, and even become promoters of these theories, which makes Professor Tang feel a little chilled from the bottom of his heart.

"Science doesn't mean that you have to be unwavering in your superstition about him, but what each of us, everywhere we learn, I want to belong to you. Professor Tang said: "Otherwise, anything you learn is not your own." ”

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

Many of the people present believed these things!

If it is usually everyone chatting and refuting rumors, it is nothing, but now that the professor says this, think about it carefully, it is really not good for scientific thinking.

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

And science also needs logic, and some words, even if they are correct, are of little value.

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

"Shocked! According to scientific statistics, where there are more mosquitoes, the easier it is for people to drown!"

I have to say that in the process of discussing chemistry and scientific literacy, Professor Tang also instilled some anti-fraud and avoidance of foolish thinking in everyone.

...

"After talking about these simple chemical truths, I want to talk about one thing next. Our school will open in September in the second half of this year, and there will be a new high-level key project, which is about the application of quantum chemistry in lithium-ion secondary batteries. At the end of this year, I may bring a group of postdoctoral fellows, and students who are willing to do this can pay attention to the school's official website. Moreover, students who are only in the undergraduate or master's degree do not need to be discouraged, this project will take a long time. ”

The previous ones are all for the general public, and this is the purpose of many doctoral students here!

As we all know, scientific research is a field that only God can access. On the day of graduation, the experiment that ordinary people do is always a repetition of the process of their predecessors, and there are known results. Research is not, it takes a strong heart, constantly breaking the rules, defying common sense, and being able to tolerate failure.

However, this is still the jewel in the crown! This is the process of creating something out of nothing, and this is the highest manifestation of human wisdom!

When it comes to quantum theory, there are generally two kinds of people doing it. The bigwigs of the former are pursuing the microcosm of Planck's time level, and the melon-eating masses of the latter are accustomed to treating this thing as science fiction content.

In some science fiction, everything is explained by quantum!

It is even said that an unknown detective author Fengyi XX has mentioned this thing several times in his detectives, and he is simply mad!

"I'll talk about the next thing. Students who can keep up with the progress can consider what I said earlier. ”

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

"Today's lecture is about the computational simulation of the physical properties of molecules and condensed matter systems...

...”

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

Then he opened his book and read it carefully.

Half an hour later, Bai Song understood what the two or three questions pointed out by the girl were, and there were still a few questions that I checked on the Internet with my mobile phone... It's so hard...

Call... Bai Song planned to continue listening to the lecture for a while.

"A study of lithium-doped aromatic carbons using the Abinitio molecular orbital method..."

......

Let's keep reading...

A class, or a lecture, is almost two hours. In the next hour, two-thirds of the people could not understand at all, and only a few dozen people could understand it. Although I can't understand the rest of the part, I was still very inspired to listen to Professor Tang talk about the application of functional analysis in chemistry.

Of course, there is no doubt that the white pine belongs to the two-third.

This is also a star effect, although I can't understand it, almost no one leaves.

After the lecture, Bai Song still breathed a sigh of relief.

Seriously, his position is called "Teaching Assistant", and he is really afraid that Old Tang will have a brain and let him go up to give a lecture, which will basically become famous once, after all, this course is videotaped, and all the courses will be saved and posted on the university's website...

The current Bai Song is not afraid of being famous, if he has a little more fame, even if he is re-brought into the field of vision by some people, he is fully prepared.

He was really afraid that these people would not come!

However, although he is not afraid of being famous, he doesn't want to be embarrassed......

At the end of the class, the students applauded.

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

"The next public class is next Saturday, I can't come, you prepare for me. After Professor Tang finished talking to the girl, he then looked at Bai Song: "You are also a teaching assistant, and you are also preparing for class." In the next class, you will talk about it in the first half, and let Jianguo talk about it in the second half. ”

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

He couldn't do it in the first half! It's just a joke!!

Also, what does statehood mean!

This girl's name is Jianguo???

Bai Song feels that he believes in science again...
