The Significance of number : the love function
Numbers are everywhere in our daily life. You need numbers to stand for hours on the clock; to calculate how much you spent on your expense; to dial when you lift your phone and call your best friend. We cannot live without numbers. It is so tiny that people almost neglect its existence.
However, People used to hate numbers when we had tough math lessons. Sometimes, math can be romantic. For my poster, I used one of the most famous mathematical love function : r=a(1-sinθ).
Here is a story behind this function about René Descartes, a famous mathematician. He had been to Sweden and met Christina, the princess of Sweden. They fallen in love with each other because both of them loved math so much. But the King of Sweden didn’t allow them to stay together because he thought René Descartes was too shabby and confiscated all the letters they communicated with each other. Before René Descartes dead, he wrote his last letter to Christina: r=a(1-sinθ). The king and minister didn’t understand the letter so they gave the letter to Christina. She draw the picture of the formula, only she herself got the meaning of letter: LOVE.
Nowadays, for those people who love math, may say ” I love you” in this mathematical way. Through calculating with numbers, finally draw a heart on the x,y-axis.
