What examples from nature does the author use to illustrate principles of physics?

The author uses patterns such as fractals, wave formations, and gravitational phenomena to illustrate principles of physics because these examples are deeply rooted in nature and help to demonstrate how physics manifests in the world around us. Fractals exhibit self-similarity and can be observed in snowflakes, coastlines, and plant growth, showcasing mathematical principles at play in natural forms. Wave formations are essential to understanding phenomena like sound, light, and ocean waves, making them accessible and relatable to everyday experiences. Gravitational phenomena are fundamental in explaining how objects interact with one another across vast distances, as seen with planets orbiting stars, which is crucial for understanding the laws of motion and gravity. These examples provide a concrete foundation for discussing complex physics concepts, highlighting the beauty and interconnectedness of nature and scientific principles.
