Difference Between Fractal and Euclidean Geometry


What is Euclidean Geometry?

Euclidean geometry is the study of shapes and figures based on the principles given by the ancient Greek mathematician Euclid in his work “Elements.” It is the branch of geometry that deals with flat shapes and surfaces, assuming that space is continuous and follows the rules of classical geometry. Euclidean geometry is characterized by concepts such as points, lines, angles, planes, polygons, and circles, and it looks at properties like congruence, similarity, and symmetry.

In Euclidean geometry, the basic assumptions are: the existence of a straight line between any two points, the extension of a line indefinitely, and the existence of a unique parallel line through a point not on a given line. Euclidean geometry forms the foundation of classical geometry and is commonly used in like architecture, engineering and navigation.

What is Fractal Geometry?

Fractal geometry is a branch of mathematics that deals with self-similar patterns and irregular shapes, often found in nature. These patterns are created by repeating a simple process over and over in an ongoing feedback loop. In other words, fractal geometry looks at irregular and fragmented shapes that repeat themselves infinitely when you zoom in or out.

Fractals are characterized intricate patterns and infinite complexity, which can be generated through simple mathematical formulas or algorithms. They are found abundantly in nature, such as in coastlines, clouds, mountains, and even in the branching patterns of trees. Fractal geometry has applications in fields like computer graphics, art, biology, physics medicine and finance. For instance, the Koch snowflake, a fractal curve, is an example of a shape with a non-integer dimension.

A common examples of fractal geometry is the Mandelbrot set, which is a mathematical set of points in the complex plane. The boundary of the Mandelbrot set is an intricate and infinitely complicated fractal.
