What do you think of the love story of Descartes and the princess?

Descartes said, "All problems can be transformed into mathematical problems." "So love can also be deduced, calculated, and designed. But in the end, you will find that even if you think about it, you can't count your heart, that's right, this is his love.

Age is not a problem, money is not a gap, there is always a person, one day, just met, and fell in love, regardless of age or others.

It is most appropriate to use Descartes's mathematics to explain that it is best to describe it in terms of partial derivatives of multivariate functions, although one or two cases can be designed to exist, and the condition for the existence of extreme values is to satisfy any situation, not an infinite number of them, which is true love.

Like a fairy tale, it is very magical, and it gave me the confidence to learn high mathematics well, because "if you learn mathematics, physics and chemistry well, you can flirt with the princess", who is not impressed.

Maybe I'm darker in my heart, I think Descartes is completely greedy for the princess's beauty and financial status, if he really likes it, he should consider not provoking the princess.

I think love can break age, I like you, what if you're older than me, I don't care, a sentence I love you is enough.

I didn't accept their love at all, because I couldn't accept someone who could be my grandfather to make love, and my family didn't agree to it.

Talent is very important, as long as you are talented, it doesn't matter how you look or age, your talent is enough to attract someone to stop for you.

These two people who know about the Baisui Mountain advertisement, sure enough, I can't afford to drink the nobles in the water, and I can't understand the love of the nobles, I can't understand it.

It's romantic, but it's a pity it's fake.

On the streets of Stockholm, 52-year-old Descartes meets 18-year-old Swedish princess Christine.

At that time, the destitute, penniless Descartes lived a life of begging, and all that was his possessions was tattered clothes and a few math books he carried with him.

One quiet afternoon, Descartes sat in the street as usual. Suddenly, someone came up to him and patted him on the shoulder: "What are you doing?"

Turning his head, Descartes saw a young and beautiful face, a pair of clear eyes like the blue water of a lake, beautiful and moving. She is the little princess of Sweden. The king's favorite daughter, Christine.

She crouched down, grabbed Descartes' math book and scratch paper, and started talking to him. During the conversation, he found that the little girl was a quick thinker and had a strong interest in mathematics.

A few days later, he was unexpectedly informed that the king had hired him as the little princess's math teacher. Descartes, full of doubts, followed the guards to the palace, and while waiting in the drawing-room, he saw the girl he had met on the street the other day. From then on, he became the princess's math teacher.

The princess's mathematics improved by leaps and bounds under Descartes' tutelage, and they began to become intimate with each other. Being inseparable every day also makes them love each other.

However, it didn't take long for their romance to reach the king's ears. The king was furious and ordered Descartes to be put to death immediately. At Christine's pleading, the king banished him back to his homeland, and the princess was placed under house arrest.

Soon after Descartes returned to France, he fell seriously ill. In the days when his life entered the countdown, he still missed the warm smiling face he met on the street day and night. After Descartes sent his thirteenth letter to Christine, he left this world forever.

There is not a single sentence written on this last letter, there is only one equation: r=a(1 sin

e)。The king could not bear to watch his beloved daughter sullen every day, so he gave her this letter. Christine, who got the letter, immediately understood the intention of the lover, found paper and pen, and began to draw the equation graphically, a heart-shaped pattern appeared in front of her, Christine couldn't help but shed tears of emotion, this curve is the famous "heart-shaped line".

This world-famous alternative Sui book is still preserved in the memorial of Descartes in Europe.

Descartes was born in France in 1596, when the Black Death broke out on the European continent, he wandered to Sweden, met the 18-year-old princess Christine of a small principality of Sweden, and later became her math teacher, and they fell in love with each other every day. Descartes fell seriously ill shortly after returning to France, and he wrote letters to the princess every day, but Christine never received Descartes' letter because she was intercepted by the king. Descartes died of exhaustion after sending Christine a thirteenth letter, which contained only a short formula:

r=a(1-sinθ）。The king could not understand it, and felt that there was not always a love talk between the two of them, so he gave the letter to Christine, who had been sullen, and when the princess saw it, she immediately understood the lover's intentions, and she immediately began to draw the figure of the equation, and when she saw the figure, she was very happy, and she knew that the lover was still in love with her, and the figure of the equation was in the shape of a heart. This is also known as the "heart-shaped line".

After the death of the king, Christine ascended the throne and immediately sent people around Europe to look for her sweetheart, but the deceased person was one step ahead of her, leaving her alone in the world, It is said that this world-famous alternative love letter is still preserved in the memorial of Descartes in Europe.
