Homonym: spiral (Staircase)
A spiral is a curve that winds around a central point, gradually moving away from or toward it. You can see spirals in nature, like in the shape of a nautilus shell or the way galaxies form in the universe. Spirals can also be found in everyday objects, such as a spiral staircase or a coil spring.
In mathematics, a spiral can be described using equations that define its shape. There are different types of spirals, like the Archimedean spiral, which has evenly spaced turns, and the logarithmic spiral, which grows wider as it turns. Spirals are fascinating because they appear in art, architecture, and even in the patterns of weather systems.
