《数学的故事》里面说到了数学家笛卡尔的爱情故事.笛卡尔于1596年出生在法国,欧洲大陆爆发黑死病时他流浪到瑞典,
1956年,斯德哥尔摩的街头,52岁的笛卡尔邂逅了18岁的瑞典公主克里斯汀.几天后,他意外的接到通知,国王聘请他做小公主的数学老师.跟随前来通知的侍卫一起来到皇宫,他见到了在街头偶遇的女孩子.从此,他当上了小公主的数学老师.
小公主的数学在笛卡尔的悉心指导下突飞猛进,笛卡尔向她介绍了自己研究的新领域--直角坐标系.每天形影不离的相处使他们彼此产生爱慕之心,公主的父亲国王知道了后勃然大怒,下令将笛卡尔处死,小公主克里斯汀苦苦哀求后,国王将其流放回法国,克里斯汀公主也被父亲软禁起来.笛卡尔回法国后不久便染上重病,他日日给公主写信,因被国王拦截,克里斯汀一直没收到笛卡尔的信.笛卡尔在给克里斯汀寄出第十三封信后就气绝身亡了,这第十三封信内容只有短短的一个公式：r=a(1-sinθ）.国王看不懂,觉得他们俩之间并不是总是说情话的,将全城的数学家召集到皇宫,但没有一个人能解开,他不忍心看着心爱的女儿整日闷闷不乐,就把这封信交给一直闷闷不乐的克里斯汀,公主看到后,立即明了恋人的意图,她马上着手把方程的图形画出来,看到图形,她开心极了,她知道恋人仍然爱着她,原来方程的图形是一颗心的形状.这也就是著名的“心形线”.
国王死后,克里斯汀登基,立即派人在欧洲四处寻找心上人,无奈斯人已故,先她一步走了,徒留她孤零零在人间...
据说这封享誉世界的另类情书还保存在欧洲笛卡尔的纪念馆里.

A few days later, he accidentally received a notice, the king hired the math teacher him little princess. Follow to notify the guard came to the palace, he saw the encounter in the streets. Since then, he's a math teacher on the little princess. The little princess, make a spurt of progress in Mathematics under the guidance of Descartes, Descartes introduced his new field of study -- Cartesian coordinates to her. Every day to get along with each other so they follow like a shadow with admiration, the princess's father the king knew the fly, ordered Descartes killed, little princess Kristen begged, king he exiled to France, Princess Kristen was placed under house arrest. Descartes back to France soon after the sick, he every day to write by the princess, King interception, Kristen has not received a letter from Descartes. Descartes was sent thirteenth letters to Kristen after he died, the thirteenth letter is only one formula only: r=a (1-sin theta). The king cannot read, think they are not always say sweet words, will the mathematician summoned to the palace, but no one can unlock, he cannot bear to see a beloved daughter feel depressed all day, just give this letter to always feel depressed Kristen, Princess see, immediately clear intention of her lover, to draw the graph of an equation, see figure, she was very happy, she knew that love still love her, the original graph of an equation is a heart shape. This is the famous "heart-shaped line".
