This Is...

Professor Qu gazed at the leisurely white clouds outside the window, then looked away and said, "Shen Qi, foreigners call him Key. He's a master key; he's opened the door to a new world, he's a miracle worker. The new drug you're taking was developed by Shen Qi. Can Shen Qi continue to create miracles? You're his wife, perhaps you understand him better."

Encouraged, Ou Ye raised her arms and shouted, "I... I'll take my medicine!"

Professor Qu said, "You don't need to take any medicine today. I'm just here for a routine ward check-up and to chat with you."

"Um, thank you, Professor Qu... I'm a little sleepy..."

"Go to sleep if you're tired."

"My students are coming over later... If I'm not awake, Professor Qu you... give them that manuscript..."

"Hey Xiao Ou, you're a patient. During clinical trials, you shouldn't be studying math!"

"Everyone needs something... to have a spiritual anchor... yawn... sleepy..."

"Alright, alright, I'll make arrangements for your students. You can get some sleep. See you tomorrow."

Ou Ye fell asleep quickly.

"Her drowsiness is more pronounced."

Professor Qu muttered to himself that he had recruited dozens of subjects, and based on the experimental data and his own observations, he believed that Ou Ye was a fairly typical case.

Professor Qu came to the table, and the manuscript that Ou Ye had been reading was placed on the table.

The manuscript was filled with mathematical formulas, densely packed and dazzling.

Suddenly, a strange light flashed in Professor Qu's eyes.

"This is... this could be... this could be the solution to that difficult math problem?"

Don't assume that doctors are bad at math; some doctors are quite good at it.

For example, Professor Qu's excellent math skills are due to the demands of his work.

In clinical trials, pharmacokinetic and pharmacodynamic models are established mathematically, with pharmacodynamics as a dependent variable, which can be a clinical endpoint, surrogate point, or biomarker. Clinical trial data processing requires the use of Numerical Analysis algorithms such as Ordinary Differential Equations, Probability Theory, and the Runge-Kutta method.

Professor Qu may not be the strongest medical expert in China, but his mathematical skills are among the best in the country.

Professor Qu was inexplicably excited as he stared intently at Ou Ye's mathematical manuscripts.

"I... I don't understand this. Is this number theory? And Elliptic Curve? This is way beyond my knowledge."

"But I feel that Xiao Ou is really amazing. Just imagine, a woman suffering from illness proved a world-class mathematical problem in her hospital room. How touching that would be for China!" Professor Qu neatly arranged Ou Ye's manuscript, then left the ward, closed the door, and instructed the nursing team to guard the ward and Ou Ye 24 hours a day.

Hospitals are always bustling with people, much like Xidan.

Xicheng Weihua Kindergarten is located near the Xidan commercial district. Shen Qi brought his daughter here after leaving the kindergarten to eat and shop.

"Nofi, are you full?"

I'm full.

"Then we'll go buy you a red dress, red shoes, and a red hair clip, and then we'll buy you a few red backpacks. When we get home, you can wear them all, and we'll take videos and photos to send to Mom."

"Yeah, I like red the most. The black and white clothes we got from kindergarten were awful."

"Let's go to the second floor, the children's clothes are on the second floor."

Shen Qi took Nofi's hand and walked out of the restaurant, taking the escalator to the second floor of the mall.

As the elevator ascended, Nofi asked, "Dad, do you know that pretty lady? The pretty lady who sat at the next table during dinner."

"I don't know her. How could I possibly know a stranger?" Shen Qi was puzzled. Why would his daughter ask such a question?

"Then why do you keep staring at that older woman?"

"When was I watching her?"

"Dad, you're not allowed to have an affair."

Do you know what an affair is?

"An affair is like finding me a new mother outside the marriage."

"Your understanding of infidelity is basically correct, but Dad would never do that. We've arrived; this is the brand of children's clothing we're looking for."

"Dad, why are you suddenly wearing glasses?"

"Because Dad looks more handsome with glasses, what do you think, Nofi?"

"Yes, that's right."

Shen Qi led Nuofei into the children's clothing store, where the staff warmly welcomed the father and daughter customers.

"My daughter likes red. Take out all the dresses, shoes, hair clips, and backpacks in your store in bright red, pink, burgundy, orange-red, and Ferrari red, according to her size, and let her try them on."

"Okay, okay, please wait a moment."

This brand of children's clothing is quite expensive; this store is a retail store, not a wholesale store.

The father and daughter were like wholesalers; the shop assistants went off to get the goods with great enthusiasm.

"Daddy, Daddy, you bought so much, I can't wear it all!" Nofi rarely went out with her father to buy dresses, shoes, and hair clips. Usually, her mother would take her to buy girls' items. After all, her mother had been a girl herself and knew girls' spending needs and aesthetic standards.

Dad's shopping style is completely different from Mom's.

Mothers usually pick out children's clothes one by one, while fathers take out everything: this, this, and this.

"This is called exhaustive search, it's fine, just buy it." Shen Qi told Nofi the theoretical basis for his shopping behavior.

"Exhaustive search... so it just means buying lots and lots of dresses?" Nofi often encountered the technical terms her father told her in her daily life. Girls her age could hardly fully understand these technical terms, but they would form a general or specific memory of them.

"Buy it then! I'll be happy even if I can't wear it all and it's just sitting in the closet." Shen Nuo Fei clapped her hands, seemingly having grasped a new truth.

"The so-called exhaustive search method can be understood as eliminating dresses you don't like until you get the one you like best, in order to buy one and then wear it. This theory is a long story, and I'll explain it to you in detail when you start elementary school. In fact, many things in life can be explained using mathematics. I really hope that you can learn math well, Nofi, but of course, don't neglect any subjects; well-rounded development is the best."

Twenty-eight red dresses, twenty-four pairs of red shoes, sixteen red hair clips, and seven small red schoolbags.

This is what Shen Qi and his daughter have gained.

After paying, Shen Qi asked the shop assistant to pack the items and deliver them to his home.

"Wow, it's so good to be rich..." A little girl in the store drooled with envy. She had also come with her father to buy a dress, but after shopping for several hours, she hadn't bought anything.

Daughters should be raised in a lavish manner, but the prerequisite for this is wealth itself.

Shen Qi subtly imparts mathematical principles to his daughter through some of her consumption behaviors in real life.

Combining theory with practice is more effective and engaging. Constantly calculating numbers and doing addition, subtraction, multiplication, and division problems at home can become quite tedious over time.
