What are the differences between the golden ratio and the rule of thirds in terms of composition in photography and design?

The golden ratio is a mathematical ratio that is often used in art and design to create visually pleasing compositions. It is a proportion that is believed to be aesthetically pleasing to the human eye. The rule of thirds, on the other hand, divides an image into nine equal parts using two horizontal and two vertical lines. The main subject of the image is usually placed along these lines or at their intersections to create a balanced composition. Both techniques are used to create visually appealing compositions in Photography and design, but they differ in their approach and application.
