By-talk 2: When Mathematics met Love

1

It’s a romantic story about Descartes. It mainly about that Descartes and the queen of Sweden at that time. The story began on a quiet afternoon in 1650, on the streets of Stockholm, 52-year-old Descartes met the 18-year-old princess Christina. The princess had a keen interest in mathematics so that she was greatly impressed by his talent as she looked at Descartes’ mathematical work. A few days later Descartes was summoned to the palace and became the princess’s math teacher. As the princess’s mathematical performance getting better, pure love between them sprouted. But the king who knew the truth was in a rage. Descartes was immediately exiled to his home country and the princess was imprisoned as well. Unfortunately, after returning to France Descartes was infected with the terrible Black Death. However, due to the affection to the princess, he still wrote 12 letters to the princess, but all of them were destroyed by the king without exception. When Descartes was lying at the point of death, the king got the letter with only one formula: “r = a (1-sin θ)”. Although the king summoned a lot of mathematicians, but no one can solve this formula. So the king relaxed his vigilance and gave this letter to the princess. Finally the princess solved the this problem and cried one’s heart out. The heart-shaped curve represented Descartes’ whole hearted love. It is said that this alternative love letter is still stored in a museum of Descartes, Europe. This is the story of Descartes’ poignant love and famous heart-shaped curve.
