Spirálas

Spirálas is an adjective used to describe something that has the shape of a spiral or that proceeds in a spiral manner. It can refer to physical objects, patterns, or processes characterized by a curved, winding path around a central point. The word derives from spirála, from Latin spira, and is commonly used in science, engineering, and everyday language.

In geometry and mathematics, a spiral is a curve that winds around a fixed center while moving away from or toward it. Classic examples include the Archimedean spiral (r = aθ) and the logarithmic spiral (r = a e^(bθ)); both are described by precise equations and have distinctive growth patterns.

Spirálas patterns and forms appear widely in nature and human-made objects. Shells of mollusks, such as snails, often exhibit spiral growth. Phyllotaxis in plants can create spiraling arrangements of seeds or leaves. Spiral galaxies and the spiral bands of storms, such as hurricanes, are prominent natural examples. In technology and construction, spiral shapes are found in screws, springs, spiral staircases, and coil cables. The term also describes helically wound structures, like DNA in biology or spiral-cut agricultural products.

In biology and medicine, certain bacteria are described as spirálos (spirilla or spirochetes) due to their curved, spiral shapes. The concept of spirálas thus spans geometry, natural phenomena, and various applied fields, capturing a common motif of curved, revolving growth around a center.
