Chaos theory focuses on nonlinear systems and has gained significant attention as it applies to various fields, from finance to biology. This theory allows for the analysis of complex systems that exhibit unpredictable behavior, making it versatile and widely applicable in scientific and theoretical discussions.

In Michael Crichton's "Jurassic Park," chaos theory is presented as a critical element in understanding the inherent unpredictability of complex systems. The popularity of this theory underscores its relevance in analyzing phenomena that do not follow simple linear patterns, reflecting its status as a trendy and fashionable concept in contemporary thought.
