I just want to be a quiet scholar

Chapter 202 Correct operation of y(x)+δy(x)

On August 8th, which is Shen Qi's planned departure date, he will fly from China to New York and from New York to Princeton, New Jersey, to start his overseas study career.

Now is the countdown stage for Shen Qi to go abroad, and he and Ou Ye are inseparable.

With the 154-day countdown to going abroad, Shen Qi and Ou Ye discussed in depth the question of when the equation x^2-Ay^2=B has an integer solution.

This is a classic problem, and the person who has studied the Diophantine equations most deeply and most successfully is Fermat.

The hypothesis of Fermat's Last Theorem is written in a document written by Diophantus. Because there are too few blank spaces in the book, Fermat is a naughty eunuch, and the proof is not completed.

Propose hypotheses, prove hypotheses, continue to formulate hypotheses, and wait for future generations to prove them.

For thousands of years, mathematicians have been obsessed with this number game.

When Wiles was teaching at Princeton, he spent ten years writing a paper in which he proved Fermat's last theorem and completed Fermat's eunuch thesis, which was a perfect finish.

The number game is not over, Goldbach's conjecture and Riemann's conjecture have puzzled number theorists for many years.

These two super-hard problems spanning centuries, the object of study is very simple - prime numbers, natural numbers that are only divisible by 1 and itself.

The ultimate proof of the ξ function model may start with the simplest Diophantine equation.

Once the ξ function model is fully proved, Goldbach's conjecture and Riemann's conjecture may be cracked at the same time.

"It's definitely a great cause that shakes the past and the present." Shen Qi said to Ou Ye, "This work is handed over to you. This is the historical mission of number theory researchers."

"It's so difficult." Ou Ye took off the rubber band from his wrist and skillfully tied his ponytail.

"Stand up." Shen Qi patted his left shoulder with his right hand.

Ou Ye tilted his head obediently and leaned on Shen Qi's shoulder: "I want to accomplish this great cause with you."

That's when the movie started.

Oh yes, this is a movie theater, one of the three places that lovers often come to.

The heroine on the big screen is very brave. She holds a submachine gun and shoots frantically, eliminating an astonishing number of zombies without losing blood.

The only trouble is the zombie boss, which cannot be destroyed by conventional weapons.

The zombie boss showed his mighty power, digging out a heart with one claw, and biting off a head with one bite.

All the teammates of the goddess of war died, and there were no dead bodies.

"Hahaha." Shen Qi laughed, he put his arms around Ou Ye, and untied the rubber band of Ou Ye's ponytail.

Ouye's ponytail was loose, and her black, straight and long hair was let loose.

Ou Ye's hair rubbed against Shen Qi's cheek, it was a little itchy, but her hair smelled good.

The fragrance, body fragrance and the faint smell of traditional Chinese medicine are mixed together.

There are lovers embracing each other, and horror movies also see the tonality of love movies.

"Aren't you afraid of my long hair covering my face?" Ou Ye asked softly with his lips pressed against Shen Qi's earlobe.

"What is your woman afraid of, you are not a ghost." Shen Qi said, and added: "I am not afraid of ghosts, I just like female ghosts."

"Hate!" Ou Ye opened his mouth and bit Shen Qi's earlobe, neither light nor heavy.The force of his mouth was lighter, and he didn't feel it.The force is heavy, afraid of biting him.

The 152-day countdown to going abroad, Shen Qi and Ou Ye spent a whole day in the library, each learning their own, and feeding each other when they were tired.

The same goes for the next few days.

Ou Ye, who had recovered from his studies, made Zhou Yuan feel a lot of pressure.

It's already the second semester of my sophomore year, and I'm almost halfway through the undergraduate stage. If I don't work hard to catch up, I won't be able to catch up.

Zhou Yu'an was slumbering and only slept 5 hours a day. He frantically studied integrable systems and differential geometry, and set himself a main attack direction to fight against Ou Ye, who specializes in number theory.

The countdown to going abroad is 145 days, and today is the weekend.

Shen Qi fulfilled his promise and brought Ouye to Beidaihe for a vacation.Traveling together is a compulsory course for lovers. As long as the heart is connected with the heart and love is with you, it is the same wherever you go.

Ou Ye never mentioned the free exercise in Switzerland again. She raised her small fist and beat Shen Qi's chest: "Beidaihe, Beidaihe, Beidaihe! My parents and I have been here more than five times."

"This is my first trip to Beidaihe, and it's beautiful." Shen Qi sat on the beach and stared up at the night sky.

There are a few tourists on the beach at night, Shen Qi and Ou Ye are one of the couples.

"It used to be called Xiao Tiantian, but now it is called Mrs. Sister-in-law, huh, man." Ou Ye muttered with his head lowered, his fingers drawing circles on the beach.

"This analogy is inappropriate, you will always be my Zixia, unique." Shen Qi continued to watch the sky at night. Tonight is cloudy, windy, and the moon appears and disappears.

Suddenly, Shen Qi grabbed a handful of fine sand and sprinkled it into the air, staring at the air very intently.

The sand fluttered in the wind and was blown away.

Shen Qi paid attention to the trajectory and speed of the sand in the air.

During the first atomic bomb detonation test, Dr. Fermi threw a handful of shredded paper into the air. Through visual observation combined with mental arithmetic, he accurately calculated the equivalent of the atomic bomb based on the flying trajectory of the shredded paper in the shock wave.

Tonight at Beidaihe Beach, cloudy and windy weather, Shen Qi was doing something similar to Fermi, he was calculating the wind speed and direction.

Ou Ye was still drawing circles. Shen Qi smoothed the circles drawn by Ou Ye on the beach, and wrote a simple formula in the same position: y(x)+δy(x)
"It doesn't make any mathematical sense to draw circles repeatedly, Ouye, can you draw a mathematical curve of y(x)+δy(x)?" Shen Qi asked.

"Super simple." Ouye immediately drew a crescent moon on the beach, which was a Lagrangian variational curve.

At this moment, the wind blows and the clouds disperse, and the moon appears. It is a crescent moon, which is exactly the same as the crescent curve drawn by Ou Ye.

Shen Qi's calculation is quite accurate, and the time error of the moon's appearance is less than 1 second.

The beautiful scenery of the good day, the beauty of the heaven, and the beautiful woman should not be disappointed.

Shen Qi put his arms around Ou Ye and pointed to the night sky: "Look, how amazing, just after you finished drawing the Lagrange crescent curve on the beach, a real crescent appeared in the night sky, I believe this is the power of love ."

The waves hit the beach, and the bright moonlight shines down. The real moonlight shines on y(x)+δy(x) on the beach, as well as the crescent curve corresponding to y(x)+δy(x).

This situation is suddenly romantic, the IQ of a woman in love will drop, and Ou Ye's little face blushed.

"The moon testifies, Ou Ye, I will always love you and take care of you." Shen Qi's forehead was against Ou Ye's forehead, and the tip of his nose touched the tip of his nose: "If I break my promise, I will never be able to draw the correct math curve."

"Don't lie to me." Ou Ye blushed to the base of his neck, his eyes blurred.

Under the moonlight, Shen Qi kissed Ou Ye.

The kiss was long and lasted a few minutes.

When the lover's kiss was over, the moon in the night sky hid in the clouds.

"You... did it on purpose, you've calculated the time." Ou Ye gasped, her body burning like fire with her first kiss.

Ou Ye liked this feeling, and his heart seemed to jump out.It doesn't matter if he is intentional or not.
