I Just Want to Be a Quiet Top Student

Shen Qi and Ouye have already moved to a separate house. The 150-square-meter house is fully equipped with furniture and electrical appliances. The upstairs 90-square-meter house has been simply furnished.

Shen Qi and Ouye lay on the bed chatting, and Shen Qi reported the family's financial information: "We brought back a total of 5.03 million US dollars from the United States, plus the 25,000 US dollar bonus you just received, our current assets are equivalent to about 100,000 US dollars. It is 35.38 million, which is living money, not including houses and cars."

"You can make a lot of money." Ouye listened to Shen Qi's report and made a comment.

The US$5.03 million brought back from the United States was earned by Shen Qi alone, including bonuses, wages, sales of academic monographs, etc.

After returning to China, Ouye also joined the money making team, and she contributed 25,000 US dollars.

"Your math scores are relatively good. From now on, you will take care of your money." Shen Qi stuffed the bank card into Ouye's hand, and said: "All the money from our marriage is in it, hard-earned money is hard-earned, so we should save it flower."

"You are really enlightened." Ouye was satisfied with Shen Qi's performance, man, the most important thing is attitude.

Ouye took Shen Qi's bank card, touched it, and returned it to Shen Qi: "You have more social experience than me, so you should manage the money."

"That's it, then I will take care of it for you." Shen Qi respectfully obeyed.

"Don't spend indiscriminately." Ouye reminded.

"Who dares to spend the money for marrying a daughter-in-law?" Shen Qi's wife has almost saved enough. She has a house, a state-distributed car, a gift from Ouye's father, and more than 30 million Chinese and Western styles. None of the weddings are too shabby.

With a smooth career and happy love, Shen Qi is a big winner in life in the eyes of others.

Shen Qi is not complacent. He realizes that he still has shortcomings in many aspects and needs continuous improvement.

The 973 project "Application and Expansion of Defect Topology Research in Condensed Matter" was finally approved, and Shen Qi was approved with a funding of 5 million yuan to meet Shen Qi's needs.

Shen Qi purchased basic condensed matter physics experimental equipment such as X-ray instruments, spectrometers, and laser devices. He was responsible for the selection and inspection of the goods, and the debugging of the equipment by himself. Shen Qi had the strongest hands-on ability in the entire center.

Shen Qi has set up a laboratory on the third floor of the mathematics building. Recently, he visits the laboratory every day to conduct experiments and collect real data.

Shen Qi is still continuing to study the origin mechanism of the complex oxide q2DEG.

Condensed matter is all-encompassing, not just complex oxides.

Shen Qi simultaneously carried out research on nanoscale amorphous alloys. The experimental material was a typical zirconium-based amorphous alloy with a nominal composition of Zr41.2Ti13.8Cu12.5Ni10Be22.5 (atomic percentage).

In order to obtain effective X-ray small-angle scattering signals, the sample needs to be prepared as a thin strip with a thickness of about 20 μm.

The preparation of samples of this size requires the use of a high-vacuum single-roller rotary quenching and stripping machine. This kind of equipment is quite expensive, and Shen Qi cannot afford it for the time being. He entrusts Yanda Institute of Technology to help prepare samples, which has such a machine.

It really costs money to do physics research. The 5 million soft sister coins are not used, and the conversion into US dollars is less than 1 million.

Shen Qi knew very well that the Department of Physics at Princeton basically couldn’t do much with $1 million. The PPPL plasma laboratory in Princeton burned nearly $1 billion a year, while Yanda’s annual research funding was only $3 billion.

For the first physics project after returning to China, Shen Qi was too embarrassed to ask the country for too much money, 5 million would be 5 million, a small amount of money can still accomplish great things, the key is to see who is using the money.

The experimental research on zirconium-based amorphous alloys is a meticulous and tedious work. Shen Qi repeats the same thing every day, adjusting the 1W2A beam receiving angle range to -3.5-0mrad in the horizontal direction and (0.36±0.18) in the vertical direction. mrad, the incident X-ray wavelength is 0.154nm, the angular resolution is 0.5mrad, the energy resolution (△E/E) is about negative cubic of 10, the luminous flux is 1×10^11cps, the distance between the sample and the detector Set to 1 meter...

The inspection of the experimental equipment and the preparation of the experiment were completed, and the whole morning passed.

Only in the afternoon can we start to do business, the machine is started, and small-angle X-ray diffraction is performed on samples of zirconium-based amorphous alloys.

Once the machine was turned on, Shen Qi had to stay in the laboratory to prevent fire or vandals from destroying it.

Buzzing, the experimental machine made regular vibrations.

At room temperature, the sample is stretched until it breaks, the detector starts to collect real-time data, and the scattering intensity pattern is measured, and the exposure time of each pattern is 5 minutes.

Shen Qi used FIT2D software to process the data of the original pattern in the laboratory. First, the scattering data of the sample and the background were normalized respectively, and then the scattering data of the background and the background were subtracted to obtain the scattering data of the amorphous sample.

Finally, some mathematical finishing is required, and fan-shaped integrals at small angles are made along the stretching direction. Today's angle, Shen Qi, is set to 10 degrees.

From morning till night, Shen Qi worked all day and got a piece of A4 paper on which the one-dimensional scattering curve of the sample was printed.

This A4 paper embodies the patience, care and sense of responsibility of researchers, as well as the ambition to seek breakthroughs.

At the end of the 19th century, a British physicist named Rayleigh discovered an incredible thing when studying nitrogen: the nitrogen prepared from the air is always heavier than the nitrogen prepared from nitrogen-containing compounds such as ammonia. Bits - 0.0064 grams.

Rayleigh spent a full two years doing experiments repeatedly, doing the same experiment, persevering, observing and verifying repeatedly, and finally came to an astonishing conclusion that there is a "lazy" gas in the air—argon. Argon means lazy in Greek.

Times are changing, and experimental equipment is being upgraded, but the tradition of experimental physicists has been continuing, to do experiments, to keep doing experiments, to live forever and to retire.

"It's very interesting to be in the lab, but I can't spend all day in the lab." Shen Qi got a piece of A4 paper a day, and he estimated that he had to collect at least 100 sheets to build a theoretical system.

This is just the field of amorphous alloys, as well as complex oxides, superconductors, various nanomaterials, and polymers and biopolymers.

The Nobel Prize in Physics is not so easy to get. Shen Qi knows that a theory without experimental data support is difficult to be recognized by most physicists.

It is necessary for graduate students and doctoral students to join the laboratory, and they will not become talented if they do not.

For a leader as big as Shen Qi, it is impossible to do experiments and calculate simulated data every day. His responsibility is to grasp the strategic direction and propose innovative ideas. Most of the specific and tedious experimental work should be handed over to his subordinates. Shen Qi occasionally supervises It's OK once.

This is back to the topic of talents. Shen Qi summoned Cui Xiaoyi into his director's office and asked, "Why is the Ph.D. in physics not yet in place? What kind of difficulties have you encountered?"
