There are various poetic curves in mathematics, and spiral is one of them. The word spiral comes from Greek, which means "winding" or "winding". For example, a plane spiral is a curve formed by winding outward from a fixed point. More than 2000 years ago, the ancient Greek mathematician Archimedes studied the spiral line. Descartes, a famous mathematician, first described the logarithmic spiral in 1683, and listed the analytical formula of the spiral. More interestingly, before his death, Jacques Bernoulli, a Swiss mathematician, asked someone to carve a humble abode-logarithmic spiral on his tombstone, and humorously wrote the epitaph "I will be resurrected after changing back to my original self".
