On August 15, this is the date of Shen Qi's plan to go abroad. At that time, he will fly from China to New York, from New York to Princeton, New Jersey, and start his overseas study.

Now is Shen Qi's countdown to go abroad, and he and Ou Ye are inseparable.

The countdown to go abroad was 154 days. Shen Qi and Ou Ye discussed in depth the problem of when there will be integer solutions when the equation shaped like x^2-ay^2=b.

This is a classic problem. Fermat is the one who has the deepest and most accomplished research on the Diopiantu equation.

The assumption of Fermat's theorem is written in a document written by Diopantu. Because there are too few blank spaces in the book, Fermat's naughty eunuch proves that it has not been completed.

Propose hypotheses, prove hypotheses, continue to propose 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 in Princeton, he spent ten years writing a paper in which he proved Fermat's Grand Theorem and completed Fermat's eunuch paper, which was a very perfect completion.

The number game has not ended, and the Goldbach conjecture and Riemann conjecture have troubled number theory researchers for many years.

These two super-difficult problems spanning centuries, the object to be studied is very simple - prime numbers, natural numbers that can only be divisible by 1 and itself.

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

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

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

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

"Go ahead to the point." Shen Qi patted his left shoulder with his right hand.

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

Then the movie began.

Oh by the way, this is a cinema, one of the three places lovers often come to.

The heroine in the big screen is very brave. She holds a submachine gun and shoots wildly, destroying an astonishing group of zombies without losing blood.

The only trouble is the zombie boss, which can't be destroyed by conventional weapons.

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

All the teammates of the goddess of war were killed, and no corpse died.

"Hahaha." Shen Qi laughed, he hugged Ou Ye and unbuttoned Ou Ye's ponytail rubber band.

Ou Ye's ponytail was scattered, and his black, straight and long hair was vented.

Ou Ye's hair rubbed against Shen Qi's cheeks, which was a little itchy, but her hair smelled very good.

The hair fragrance, body fragrance and a faint Chinese herbal smell are mixed together. This is the unique breath of Ouye, and you can only enjoy it within a short distance.

There are lovers embracing each other, and horror movies also show the tone of the romance movie.

"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 are your own women afraid of? You are not a ghost." Shen Qi said, adding: "I am not afraid of being a ghost, I just like female ghosts."

"Hate!" Ou Ye opened his mouth and bit Shen Qi's earlobe, not light or heavy. The strength of his lower mouth was lighter, but he didn't feel it. The strength was heavy, and he was afraid that he would bite him.

The countdown to 152 days abroad, Shen Qi and Ou Ye stayed in the library all day, learning their own things, and feeding each other when they are tired of studying.

The same goes for the next few days.

Ou Ye, who was brave enough to return to his courage in his learning state, made Zhou Yuan feel extremely stressed.

I have been in the second semester of my sophomore year, and I am almost halfway through my undergraduate degree. If I don’t try hard to catch up, I will not be able to catch up.

Zhou Yu'an hangs the beam and stings his thighs, and only sleeps for 5 hours a day. He frantically studies the integrative system and differential geometry, setting a main attack direction for himself to fight against Ou Ye, who specializes in number theory.

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

Shen Qi fulfilled his promise and took Ou Ye to Beidaihe for vacation. Traveling together is a compulsory course for lovers. As long as your heart is connected and your love is with you, you will be the same wherever you travel.

Ou Ye no longer mentioned the free trip to Switzerland. She raised her fist and hit Shen Qi in the chest: "Beidaihe, Beidaihe, Beidaihe! My parents and I have been here more than five times."

"This is my first time traveling to Beidaihe, it's quite beautiful." Shen Qi sat on the beach, staring at the night sky intently.

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

"In the past, I called her Xiao Tiantian, but now I call her sister-in-law, haha, man." Ou Ye lowered his head and muttered, drawing circles on the beach with his fingers.

"This metaphor is inappropriate. You will always be my purple clouds, unique." Shen Qi continued to observe the celestial phenomena at night. Tonight, it was cloudy, windy, and the moon appeared and disappeared from time to time.

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

The sand is blown away in the wind.

Shen Qi is concerned about the movement trajectory and drifting speed of sand in the air.

When the first atomic bomb detonation test was in progress, Dr. Fermi threw a handful of shredded paper into the air. He observed and combined with mental arithmetic, and accurately calculated the equivalent of the atomic bomb based on the flying trajectory of shredded paper in the shock wave.

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

Ou Ye is still drawing circles. Shen Qi smoothed the circles drawn by Ou Ye on the beach and wrote a simple formula at the same position: y(x)+δy(x)

"There is no mathematical meaning to draw circles repeatedly. Ou Ye, can you draw the mathematical curve of y(x)+δy(x)?" Shen Qi asked.

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

Just then the wind blew and the clouds dispersed, and the moon appeared. It was a new moon, exactly the same as the new moon curve drawn by Ou Ye.

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

Good times and beautiful scenery, beautiful weather, and beautiful women should not be disappointed.

Shen Qi hugged Ou Ye and pointed to the night sky: "Look, how magical. As soon as you finished drawing the Lagrangian crescent moon curve on the beach, a real crescent moon appeared in the night sky. I believe that this is the power of love."

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

This scene suddenly turns romantic, and the IQ of a woman in love will decrease, and Ou Ye's little face turns red.

"The moon testifies, Ou Ye, I will love you forever and take care of you." Shen Qi's forehead was pressed 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 draw the correct mathematical curve."

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

Under the moonlight, Shen Qi kissed Ou Ye.

The kiss was long and lasted for several minutes.

When the kiss between lovers ended, the moon in the night sky hid in the clouds.

"You... did it on purpose and calculated the time." Ou Ye panted, and the first kiss made her body burn like fire.

Ou Ye likes this feeling, and his heart seems to be about to jump out. Just do it on purpose. It doesn’t matter if he deliberately or unintentionally.
Chapter completed!
