In Stockholm in 1650, 52-year-old mathematician Descartes met 18-year-old Swedish princess Christine. Descartes was very poor and didn't want to ask for alms from others. He just studied math problems with a broken pen and paper every day. One day, Christine's carriage passed by the street and found Descartes studying mathematics. Asked the princess as she got off the bus. Finally, Descartes found that the princess was very talented in mathematics. A few days later, Descartes was informed that the king asked him to be Princess Christine's math teacher. Descartes and Christine fell in love in the next few years. The king found and killed Descartes. In Descartes' last love letter to Christine, the mathematical coordinate equation of r = a( 1-sinθ) appeared, which was solved into a heart-shaped pattern, that is, the famous "heart-shaped line". This love letter was finally collected by Descartes Museum in Europe.
