Far Away
Shen Qi wrote a Differential Equation, and there are many different ways to solve this Differential Equation.
After thinking for a moment, the girl solved the equation using Infinite Series, wrote "Please review, Teacher Shen" in her notebook, and then handed the notebook to Shen Qi.
Shen Qi glanced at the notebook, marked it with a checkmark, and then left.
If Shen Qi were to create a final exam paper for first-year Advanced Algebra students in the mathematics department, this question would definitely be included.
Since the girl was able to give the correct answer in a short time, Shen Qi couldn't say anything; let her do whatever she wanted.
Students who like to sleep in class are either hopeless underachievers or exceptionally gifted high achievers.
After finishing his work for the day, Shen Qi changed into his sportswear and went for a run at the May Fourth Stadium.
One of my running buddies is Associate Professor Xu Zhou from the School of Physics.
Xu Zhou and Shen Qi went running together to build up their physical fitness.
After running 5000 meters, Xu Zhou was able to keep up with Shen Qi's pace.
After running 10,000 meters, Lao Xu couldn't run anymore, but Shen Qi kept running.
Shen Qi ran 12,000 meters and sat down next to Xu Zhou.
Xu Zhou unscrewed the cap of the mineral water bottle and handed it to Shen Qi: "Professor Shen, you're incredibly fast. I've seen it all."
"Old Xu, when are you leaving?" Shen Qi asked, taking the bottled water.
"Next month." Xu Zhou's scientific research project has passed the internal review of Yenching University, and it should only be a matter of time before it is approved by the relevant ministries.
"What's the first stop?" Shen Qi was quite interested in Lao Xu's scientific expedition project.
"The Three Rivers Source Region." Xu Zhou is an expert in atmospheric physics. He is very grateful to Shen Qi. Shen Qi's remarks helped his project pass the school's internal review, allowing the scientific expedition to proceed as planned.
"The Three Rivers Source Region is a wonderful place, with many famous snow-capped mountains. Do you have any mountaineering plans for this scientific expedition?" Shen Qi asked again.
Xu Zhou replied, "No, we're not experts in mountaineering. This time, we'll just collect data at the foot of the mountain—atmospheric, hydrological, geological, and other data. Actually, my team is like a navy; we're better at operating in the ocean."
Xu Zhou's scientific expedition this time is to conduct in-depth research on the issue of global warming.
Their scientific expedition route began in the Three Rivers Source Region Plateau region, heading east and finally entering the Arctic Ocean.
The Qinghai-Tibet Plateau is considered a heat source for the Northern Hemisphere in summer and a cold source in winter.
Global warming, the large-scale melting of Arctic glaciers, and abnormally high temperatures in summer in various countries of the Northern Hemisphere—how to improve these abnormal phenomena is the subject of Xu Zhou's research.
"The Qinghai-Tibet Plateau is the air conditioner of the Northern Hemisphere, but now, the air conditioner is malfunctioning. Lao Xu, your scientific expedition is very meaningful, and I look forward to your major research progress." Shen Qi strongly supported Xu Zhou's scientific expedition project.
"Satellite inversion combined with numerical model analysis has its advantages, but satellite data and Computer Science numerical models still have some errors, especially in their ability to describe the complex underlying surface of the plateau. Therefore, field scientific expeditions still have irreplaceable scientific value. Regarding the issue of global warming, I would like to sincerely consult Professor Shen on its specific physical processes and dynamic mechanisms."
Xu Zhou took a sip of mineral water and said, "Professor Shen, I have read all your papers and monographs. There are two articles that I have studied repeatedly. One is 'On Complexity,' which you wrote when you were working at Princeton. This article has a particularly in-depth analysis and prediction of turbulence and Chaos Theory, which fascinates me. The other is your analytical work on the Navier-Stokes equations published last year. You provided the solution and the general solution, but I am more interested in the subsequent specific applications of the Navier-Stokes equations."
Shen Qi smiled and said, "Then see you at the Three Rivers Source Region."
Xu Zhou asked, "Are you setting off with our Scientific Expedition Team, or do you have other plans?"
"Your Scientific Expedition Team should proceed according to the established plan. Don't worry about me. I'll come find you when conditions permit. Come on, Lao Xu, let's run another 5 kilometers." Shen Qi pulled Xu Zhou to continue running. Scientific research is a job that combines physical strength and intelligence. Without a strong physique, not only can the scientific research mission not be completed, but there is also a possibility of something going wrong during the scientific research process.
Old Xu gritted his teeth and ran another 5 kilometers, until he was so tired that he cramped up. He couldn't run anymore and lay down on the grass to rest.
Shen Qi ran a half marathon in one go and still had plenty of energy left.
As the sun sets and students finish their classes, the number of college students exercising in the stadium gradually increases.
One running team was quite distinctive; the dozen or so members wore matching white T-shirts with the logo of the Yanda Mountain Eagle Club.
Each member of the Mountain Eagle Club carried a bag containing 15 kilograms of water, and they ran in circles while carrying this weight.
There are two most famous student organizations at Yenching University: the Youth League School and the Mountain Eagle Club.
The core activity of the Mountain Eagle Club is summer mountaineering, and the Mountain Eagle Club has conquered almost all of China's peaks above 6,000 meters.
This summer, in July and August, the Mountain Eagle Club will continue to hold summer mountaineering activities.
May and June are crucial months for mountaineering preparation. The Mountain Eagle Club uses a mentorship system, with experienced members guiding newcomers through track runs at Yenching University or from Yenching University to Fragrant Hills and then up to Incense Burner Peak.
More professional training is conducted at the Huairou Climbing Base, and the newcomers' training ground is the 3,000-meter-high North Peak of Wutai Mountain.
It's not difficult for Yenching University students to get into the Mountain Eagle Club; the difficult part is getting into the Mountain Eagle Club.
The designated location for the Mountain Eagle Club's winter training is the North Peak of Mount Wutai. Once they leave this "newcomer village," they are qualified to join the Mountain Eagle Club's mountaineering team and challenge more difficult and higher snow-capped mountains.
As Shen Qi ran, he ended up running into the Mountain Eagle Club's ranks.
"Hey, Professor Shen!" The members of the Mountain Eagle Club spotted Shen Qi, who had blended into the group.
"Friendly troops, friendly troops." Shen Qi adjusted his breathing rhythm, signaling the Mountain Eagle Club's training team to ignore him and let him go.
Carrying 15 kilograms of water while running is not easy, but none of the members of the Mountain Eagle Club complained or said they were tired, because they knew that once they got to the mountains, carrying dozens of kilograms of tents and equipment on their backs was the norm.
The members of the Mountain Eagle Club come from various departments of Yenching University, mainly undergraduates. After a round of weighted running, they stopped to rest.
The twelve members of the training team were mostly male, with three females as well.
Shen Qi sat down next to a girl and said to her, "Hey classmate, I see you everywhere. Are you a member of the Mountain Eagle Club?"
This girl was the one who had dozed off in class that morning. She nodded and said, "Yes, my name is Zeng Linna, a first-year student majoring in Financial Mathematics in the School of Mathematical Sciences. Please give me your guidance Professor Shen."
"Linna, now that you're from the Mountain Eagle Club, I'm relieved." Shen Qi knew the Mountain Eagle Club's recruitment standards: they didn't recruit students who failed courses, those with poor moral character, or those who were spoiled.
Zeng Linna's ability to join the Mountain Eagle Club and enter the June training team demonstrates her excellent academic performance; she at least didn't fail any courses in her first semester of freshman year. She must have passed the Wutaishan winter training test, otherwise she wouldn't have been able to enter the June training team, which shows that she has strong perseverance and high physical and mental resilience.
Yenching University has many top students, and their reasons for joining the Mountain Eagle Club are varied. The current president comes from the Chemistry Department. His grades are so good that he is exempt from several courses. He was so bored that he joined the Mountain Eagle Club to kill time.
Mountain climbing is dangerous, and few students join the Mountain Eagle Club for physical exercise. Regular sports clubs and associations such as the Running Club, Table Tennis and Badminton Club, and Swimming Club are more suitable for physical exercise.
"Why did you join the Mountain Eagle Club?" Shen Qi asked Zeng Linna.
Zeng Linna: "The club president said that the Mountain Eagle Club must have female members, preferably pretty and skillful young ladies, so I joined."
"That's a perfectly valid reason," Shen Qi said with a smile, then asked, "What are your challenges for this summer vacation?"
Zeng Linna gazed into the distance and said longingly, "Maqinggangri."
"Maqinggangri, sacred mountain, I really want to go there too." Shen Qi gazed into the distance, where there was poetry and fields, as well as snow-capped mountains and his imagination.
