What do we use the golden ratio also known as phi for?
The main use for the golden ratio is its aesthetic appeal - in art and architecture. Rectangles with the golden ratio as their aspect appeal to the human mind (for some reason). So various aspects of the Parthenon in Athens, for example, have dimensions whose ratio is phi. Phi is closely related to the Fibonacci sequence: the ratio of successive terms of the sequence approaches phi and so, just like the Fibonacci sequence, phi appears in many natural situations. However, there is no particular application based on phi.
Why is the golden ratio used?
There are two main areas where the ratio is used and they are for different reasons.One reason is that the human mind finds the Golden ratio aesthetically pleasing. It is, therefore, used in art and architecture.The second reason is directly related to its mathematical properties (the ratio of the whole to the larger part is the same as the ratio of the larger to the smaller parts). This is used in designing paper sizes like the A and B series. Divide an A3 sheet in half and you will get two A4 sheets which have the same aspect ratio as the A3. Repeat and you get two A5s with the same property and so on.
Where are irrational numbers used?
Pi is used in work with circles or ellipses. For example, how far a car will move in one rotation of its tyre. That may seem a silly question but that is how the odometer works. Irrational square roots will occur in many measurements. The diagonal of a square or the principal diagonal of a cube will always be irrational. That will also be the case for most rectangles and cuboids. The number e has many uses in advanced mathematics. In art and architecture, the Golden Ratio is an irrational number. The Fibonacci sequence, which crops up in nature in many situations, is closely related to the Golden Ratio. These are some examples.
What Roman art is used today still?
Roman art that is still used today includes the design of buildings and columns that are used in architecture and city planning to this day. Techniques like contrast and bass relief are also still used today.
Why are Fibonacci numbers so special?
Fibonacci numbers are important in art and music. The ratio between successive Fibonacci numbers approximates an important constant called "the golden mean" or sometimes phi, which is approximately 1.61803.

What is the golden ratio in art?
The golden ratio was a mathematical formula for the beauty. The golden ratio in the Parthenon was most tremendous powerful and perfect proportions. Most notable the ratio of height to width on its precise was the golden ratio.
What are some modern examples of math that seem to use the same ideas as the ancient greek math?
Pythagorean Theorem would be the first thing to come to mind. Well, this is kind of more related to art/architecture, but there is the golden rectangle and the golden ratio. The golden ratio is represented by the Greek letter phi, which appears as a circle with a slash going through it. It is a value representing the ratio of the lesser to the greater when the ratio of the lesser to the greater is the same as the ratio of the greater to the whole. In Ancient Greek, architects used this technique to create beautiful buildings and works of art, where the ratio of the length to the width of the rectangle in one of the structures (or vice versa) is equal to the golden ratio.
What is the golden ratio and why is it used?
The golden ratio is 1:1.1618...... This is used in art when making the proportion of the body and the legs. Normally the legs would be 1.1618.. and the top will be the 1. This is counted as the most beautiful proportion

What are some real life examples of the Golden Ratio?
You read about all the math related aspects of the golden ratio, and now you want to see it applied to real life, right? Well, you already know about various ways the golden ratio appears in real life, and you probably haven't even thought about it at all! ---- One of the first peoples to use the golden ratio in their art, architecture, and other aspects of daily life was the Egyptians. They called the golden ratio the "sacred ratio" and used it in their hieroglyphics and pyramids, as well as other monuments to the dead. ---- The sides of the Egyptian pyramids were golden triangles. Additionally, the three-four-five triangle is a golden ratio between the five unit side and the three unit side. The Egyptians considered this kind of right triangle extremely important and used it also in the pyramids. ---- ---- The Egyptian hieroglyphics also contained many proportions based on the golden ratio. The letter h, for example, is the golden spiral. Additionally, p and sh are created using golden rectangles ---- However, the use and occurance of the Golden Ratio in aesthetics doesn't end with the ancient Egyptians. It was used by the Pythagoreans, Greeks, Romans, and artists during the Renaissance. ---- The frequent appearance of the Golden Ratio in the arts over thousands of years presents us with an interesting question: Do we surround ourselves with the Golden Ratio because we find it aesthetically pleasing, or do we find it aesthetically pleasing because we are surrounded by it?In the 1930's, New York's Pratt Institute laid out rectangular frames of different proportions, and asked several hundred art students to choose which they found most pleasing. The winner? The one with Golden Ratio proportions.
