Symmetry is often used in design and art to make it more appealing to us. From the architecture of buildings to the design of household objects and products, symmetry is frequently used to make the things we interact with every day more visually pleasing. Our bodies have a natural symmetry that is essential to our health and well-being. The left and right sides of our bodies are generally mirror images of each other, and our internal organs are arranged symmetrically to optimize function and efficiency. Symmetry is a fundamental concept in mathematics and science, with many natural phenomena exhibiting symmetry. For example, the structure of snowflakes, crystals, and molecules all exhibit various forms of symmetry. People often display symmetrical behavior during social interactions. We tend to mimic each other's posture, gestures, and facial expressions, creating a sense of harmony and rapport. Symmetry can influence decision making. For example, people tend to prefer symmetrical faces when deciding if another person is trustworthy or reliable. Symmetry can also impact safety and efficiency in various systems. Engineers and designers may use symmetry to distribute loads, balance weight, or optimize airflow to reduce resistance and increase efficiency.
