Chapter 280: A Woman Transforms into a Man: Technology in the 70s and 80s 34

The performance of this type of nuclear magnetic resonance machine produced by Egger is still quite good, and it will still be the mainstream model on the market in another fifty years.

The human body is made up of atoms, and each atom has its own vibration frequency.

There are electrons surrounding the atoms, which can be regarded as small magnetic field environments.

The most abundant element in the human body is water, and water contains a large number of hydrogen atoms. Nuclear magnetic resonance uses hydrogen atoms to form images.

Under normal circumstances, the atoms in the human body are arranged in disorder.

They follow their own magnetic fields, cancel each other out, and do not show magnetism.

If the external magnetic field is strengthened, the hydrogen atoms will break away from the original magnetic field and rearrange themselves.

At this time, if an RF pulse is added, the hydrogen atoms with the same frequency as the RF pulse will resonate.

After the RF pulse disappears, these resonant hydrogen atoms will slowly recover to their original direction and amplitude.

This recovery process will emit a corresponding signal, and we can draw an image of the human body by detecting this signal.

The nuclear magnetic resonance machine needs to maintain a high magnetic field and high uniformity in the target area, so superconducting materials are needed.

After Jiang Lan returned to China, he did not take a break and quickly began to arrange experimental tasks.

At this time, the leaders of National Tsing Hua University came over and talked to him about the establishment of the laboratory and the problem of guiding students.

Jiang Lan remembered that he was still a professor on the job at National Tsing Hua University.

He seemed to have never attended a class, and he felt a little guilty.

The school leader was also polite, "Professor Jiang, it's okay if you don't teach classes. You have to teach a few students. Your experimental team used to be a collection of borrowed people. Why don't you consider forming one yourself?"

Jiang Lan felt that the school leader's consideration was right, so he directly established the Jiang Lan Laboratory and publicly recruited laboratory researchers.

In China, when an unknown person starts a project, there will be a lot of people scrambling to participate.

Not to mention a super scientific genius like Jiang Lan who is young and powerful.

Everyone is not stupid. With Jiang Lan's high-productivity.

Even if you do odd jobs in his laboratory, you will have a golden sign in the future, and it is most suitable to use it for gold plating.

Following others may not necessarily lead to any results, but following Jiang Lan, the future is limitless.

The scientific research circle is already completely boiling. Even the top scientific research leaders in the country are tempted and want to send their children and grandchildren to Jiang Lan.

Even Professor Liu, who has a good relationship with Jiang Lan, can't help but be tempted, but unfortunately his son is too old and his grandson is too young, so they can't catch up with this wave.

Professor Liu himself can't catch up, but other people who can catch up are roundabout, wanting him to help and plead for them. Professor

Liu is also very embarrassed. It's really hard for him to bring this up.

Besides, there are more than a dozen people asking for help, and he can't help everyone. It's better to pretend that he doesn't know.

Jiang Lan does not mind having connections, as long as the ability is up to standard.

He will not allow such things as tampering to make up the numbers to happen under his hands. It

is also very common for children to inherit their father's business in the scientific research community. In order to make their children's resumes look better, many parents put their own scientific research results under their children's names. Many people have a few SCI papers at a young age.

A good resume is useless. Jiang Lan does not look at resumes, and does not care about your background. He has his own set of assessment methods.

After the laboratory was publicly recruited, he received more than 2,000 resumes in a short period of time. He really did not have the patience to read them.

He simply made a test paper and organized an exam, letting the applicants speak with their scores.

After the test results came out, Jiang Lan found that the test paper he made seemed a bit difficult.

At least for people who were born in the 1980s, this test paper was quite difficult.

Jiang Lan thought that the basic questions were hellish for the candidates.

The professors of National Tsing Hua University took the test paper home out of curiosity, and many people did not even get 80 points.

The candidates were even worse off. 99% of them did not even get a passing score, and many even scored in the single digits.

But despite this, 23 people still passed, and one person even scored 83 points.

Jiang Lan expected to recruit about 10 people. If there were too many, he would not have the energy to coach them, so he had to cut off a large number.

Jiang Lan decided to interview all of them before deciding which ones to stay and which ones to leave.

Among these 23 people, 16 were male and 7 were female.

The oldest is 35 years old, the youngest is 19 years old, and their hometowns are also different.

After the interview, Jiang Lan found that most of them were from families engaged in related industries, and only two girls were truly free-spirited, and they relied on their own efforts to enter the university.

Aristocrat from a poor family, in fact, most of them are not even from a poor family, but just ordinary people.

The scores of the two girls were the lowest among the 23 people, but Jiang Lan still hired them.

In the end, he selected 6 men and 4 women and hired them as researchers in his laboratory.

The boy who scored 83 points thought he had scored the highest score and had already won, but he didn't expect to be eliminated in the end.

When he learned that the two girls who ranked last in the written test were both selected, he was completely furious.

"Professor Jiang, I don't accept it. On what basis do you hire them? And not me?"

Jiang Lan frowned, "It's my lab. Who I want to hire is my business. What does it have to do with you?"

"Professor Jiang, I need a fair and reasonable explanation. I was clearly the first in the written test. Why can't I be better than the last two in the written test? Moreover, these two are women. What kind of results can a woman achieve in scientific research?"

Jiang Lan sneered, "Do you know why I didn't hire you? Because you are too utilitarian. You do scientific research for fame and fortune. You are not a person who loves scientific research. Moreover, you are extremely arrogant and discriminate against women. This is a problem with your character."

"I don't accept it. What I said is right. What's wrong with people pursuing a good life? Besides, women can't compare with men in scientific research. Why hire them and not me?"

[I'm so angry that my fists are stiff. Where did this chauvinist pig come from? ]

[I really want to give him a big slap in the face. ]

Jiang Lan was too lazy to say anything to him. This

kind of person has his own set of logical thinking, and is particularly stubborn and ignorant. People like them never think they have made any mistakes. They will only blame others, blame the sky, the earth, their parents, society, and women.

Anyway, the whole world is wrong, but they are the most sober.

When you meet someone with different values, don't argue. There is no point.

"You go find a place that suits you. This place is not suitable for you."

The boy was so angry that he raised his fist and hit Jiang Lan.

Before the bodyguard next to him could rush up, the boy who hit him was kicked to the ground by Jiang Lan.

"Professor Jiang, are you okay?"

The bodyguards were also shocked. If something happened to Jiang Lan, they would not be responsible.

"It's okay, take this man away."

Jiang Lan looked down at the boy lying on the ground, "Character is more important than ability, you are still far from it."

Alas, in terms of cultivating talents, there are often heavy responsibilities and a long way to go.
