Simplicity and Versatility
Most of the shapes we see around us have a surprising simplicity. Circles, squares, triangles and other basic geometric shapes are common in nature and design. This is no coincidence: the simplicity of the shapes makes them universal and easy to perceive. For example, circles symbolize infinity and harmony, while squares are associated with order and stability. Such shapes are easily integrated into various contexts and are easily perceived by the human brain.

Functionality and Ergonomics
Most shapes in product design and architecture also have a practical purpose. Ergonomics, the science of interaction between humans and the environment, makes extensive use of basic shapes to create comfortable and effective solutions. For example, the shape of a chair or door handle is often designed with human anatomy in mind to ensure comfort and functionality.

Impact on perception and emotion
Shapes have a significant impact on our perception and emotional state. Different shapes can evoke different emotions and associations. Round shapes are often perceived as friendly and soft, while sharp angles can create a sense of tension or aggression. This effect is widely used in graphic design, advertising, and art to convey the desired mood and message.

Shapes in Nature
Nature abounds with examples of the use of various shapes. The shape of seashells, honeycombs, and butterfly wings demonstrate how evolution and adaptation can lead to the formation of optimal solutions for survival. These shapes are often used as inspiration for designers and engineers seeking to create innovative and effective solutions.

Conclusion
Most of the shapes that surround us are not just geometric abstractions. They have deep meaning and impact on our perception and behavior. From simplicity and functionality to emotional impact and natural examples, shapes play an important role in our lives. Understanding these aspects helps us better perceive the world around us and create more harmonious and effective solutions in design and architecture
