If you think about it carefully, what Professor Tang said is right.
The skin is a layer of defense tissue that isolates external substances, not the stomach, so how can it absorb the substances in the mask? At most, it can just replenish water, and the time is very short, which can only last for a few minutes after the mask is removed.
Those very expensive supplements, when taken, are not only no different from ordinary things, but may also contain excessive heavy metals.
Anyone who has studied biology knows about 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 made of carbon. There is no difference between artificial and natural ones, but I just believed what was said in the advertisements.
Is this the science we study?
Don’t the undergraduates and graduate students here understand this?
But why do most people still pay the IQ tax obediently?
This is a very serious problem - what you have learned does not yet belong to you.
Does water that has been boiled multiple times contain high levels of nitrite? Is natural weakly alkaline water good for health? Can a magnetic field turn the water in a cup into small molecules for easier absorption?
Believing this is just like how many people still believe that the sewer system in Bluebird City was built by a certain colonial country. But anyone with a common sense will know that it is impossible.
However, everyone is used to not using their brains.
Professor Tang has discovered many misinterpretations of science in recent years. Some of these misinterpretations are due to the need to attract traffic, while others are due to a lack of scientific thinking.
This is not the biggest problem, but many college students and even PhD students still choose to accept these theories and even become promoters of these theories, which makes Professor Tang feel heartbroken.
"Science doesn't mean you have to have unwavering superstition about it, but I hope that everything we learn anywhere belongs to us." Professor Tang said, "Otherwise, whatever you learn is not yours."
Professor Tang gave a random example and the whole classroom started whispering.
Many people present believed these things!
If it was just a normal chat among everyone, refuting rumors, there would be nothing wrong, but now that the professor has said this, if I think about it carefully, I realize that my scientific thinking is really not up to par.
This is why many highly educated people may be defrauded.
Moreover, science also requires logic. Some words, even if they are correct, have no value.
For example, there are many mosquitoes in summer, it is very hot in summer, and many people swim, so many people drown.
"Shocking! Scientific statistics show that the more mosquitoes there are, the more likely people are 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 thinking methods and ways of avoiding being deceived.
…
"After talking about these simple chemical principles, I want to talk about one thing next. Our school will start the second half of this year in September. There will be a new provincial key project on the application of quantum chemistry in lithium-ion secondary batteries. At the end of this year, I may lead a group of postdoctoral fellows. Students who are interested in this area can pay attention to the school's official website. In addition, students who are currently in undergraduate or master's programs do not need to be discouraged, as this project will take a long time."
The previous parts are all for the general public, but this part is the reason why many doctoral students come here!
As we all know, scientific research is a field that only gods can touch. When ordinary people graduate, the experiments they do are always repeating the processes of their predecessors, with known results. But scientific research is not like that. It requires a strong heart, constantly breaking the routine, violating 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!
There are generally two types of people doing research on quantum theory. The former are the big guys who are pursuing the microscopic world at the Planck time level, while the latter are the spectators who are used to treating this as science fiction.
In some science fiction novels, everything is explained using quantum mechanics!
It is even said that a certain unknown detective novel author, Feng Yi, has mentioned this thing several times in his detective novels. It is simply insane!
"I will explain the following 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 class.
"Today's main topic is computational simulation of the physical properties of molecules and condensed matter systems...
..."
After Professor Tang finished his first sentence, Bai Song understood and didn't need to listen to the rest.
Then he opened his book and read it carefully.
Half an hour later, Bai Song finally understood the reasons for the two or three problems pointed out by the girl. He even checked the results of several of these problems on his mobile phone... It was too difficult...
Huh...Bai Song planned to continue attending class for a while.
"Studies of lithium-doped aromatic carbon compounds using the abinitio molecular orbital method have shown that..."
…
Let's continue reading...
A class, or a lecture, lasted about two hours. In the last hour of class, two-thirds of the students could not understand it at all, and only a few dozen people could understand it. Although I couldn't understand the rest of the class, I was still very inspired by Professor Tang's talk about the application of functional analysis in chemistry.
Of course, there is no doubt that white pine belongs to that two-thirds.
This is also the star effect. Although no one could understand what was said later, almost no one left.
The class was over, and Bai Song breathed a sigh of relief.
To be honest, his position is called "teaching assistant". He is really afraid that Old Tang will suddenly have a brainwave and ask him to give a lecture. He will basically become famous after just one lecture. After all, the course is recorded, and all the courses will be saved and posted on the university website...
Bai Song is not afraid of becoming famous now. If he becomes more famous, even if he is included in the attention of some people again, he is fully prepared.
He was really afraid that these people would not come!
However, although he is not afraid of being famous, he also doesn't want to embarrass himself...
After the class ended, the students applauded.
Professor Tang also relaxed, walked down from the podium and came to the girl.
"The next open class is next Saturday. I won't be here. You prepare for the class for me." Professor Tang said to the girl, then looked at Bai Song: "You are also a teaching assistant, you should prepare for the class as well. In the next class, you will teach the first half, and Jianguo will teach the second half."
"What!" Bai Song was still confused! He was asked to talk about the first half?
He was not good in the first half! This is a joke!!!
Also, what does it mean to establish a nation?
This girl's name is Jianguo???
Bai Song felt that he believed in science again...
