A spiral is a curve that winds around a central point, moving progressively farther away from that point as it revolves. Spirals can be found in nature, such as in the shells of snails, the arrangement of seeds in a sunflower, and the shape of galaxies. They can be classified into different types, including the Archimedean spiral and the logarithmic spiral. Spirals are also used in various fields, including art, architecture, and mathematics. In art, they create visually appealing patterns, while in architecture, they can be seen in structures like staircases. Mathematically, spirals are studied for their unique properties and applications in physics and engineering.
