During the Renaissance, mathematicians took special interest in how many objects in nature reflected mathematical principles. As they discovered connections, they developed mathematical ideas to help us understand the relationship between math and nature.

The concept of the golden mean, also known as the golden measure, was used by many Renaissance artists and architects, who learned about it from studying the ancient Greeks. It describes what people thought was a "visually pleasing" rectangle.
