ciklas

Ciklas is a Lithuanian term that denotes a recurring sequence of events or a complete series that repeats after a fixed interval. The word derives from the Greek kyklos, via Latin cyclus, and in Lithuanian it is used to describe the set of phases or stages that together form a continuous loop.

In science and everyday life, ciklas describes natural and man-made repetitions. In biology, common examples include the cell cycle, the life cycle of organisms, and seasonal or reproductive cycles. In earth and environmental sciences, cycles such as the lunar cycle or the solar activity cycle illustrate how periodic patterns emerge over time. In economics and social sciences, the business cycle refers to alternating periods of expansion and contraction in economic activity, while cultural or fashion cycles describe recurrent trends.

In technology and engineering, cycles appear in engines, periodic control systems, and signal processing where repeating patterns are fundamental to operation. In mathematics and computer science, a cycle is a closed path in a graph or a periodic sequence. Cycle detection is a standard problem in algorithms, helping to identify repetitions or recurring states in data structures and processes.

The concept of a ciklas is closely related to ideas of periodicity, repetition, and rhythm. It is used across disciplines to model, analyze, and predict regularities in time or space, with key characteristics including period, frequency, and phase.
