History of Geometry
Geometry (from the Ancient Greek: γεωμετρία; geo- "earth",
-metron "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. Geometry arose independently in a number of early cultures as a body of practical knowledge concerning lengths, areas, and volumes, with elements of formal mathematical science emerging in the West as early as Thales(6th Century BC).
By the 3rd century BC, geometry was put into an axiomatic form by Euclid, whose treatment—Euclidean geometry—set a standard for many centuries to follow. Archimedes developed ingenious techniques for calculating areas and volumes, in many ways anticipating modern integral calculus. The field of astronomy, especially as it relates to mapping the positions of stars and planets on the celestial sphere and describing the relationship between movements of celestial bodies, served as an important source of geometric problems during the next one and a half millennia.Slide8

Fractal
Geometry1A geometric figure that appears irregular at all scales of length, e.g. a fern2
A geometric figure which has a Hausdorff dimension which is greater than its topological dimension3Having the form of a fractal4A mathematically generated pattern that is endlessly complex Fractal patterns often resemble natural phenomena in the way they repeat elements with slight variations each time
5A kind of image that is defined recursively, so that each part of the image is a smaller version of the whole6A fractal is a shape where self-similarity dimension is greater than topological dimension7A geometric entity characterized by self-similarity (see figure 2): the whole entity is similar to a smaller portion of itself, but has a higher level of recursion (see recursion) Therefore, it can usually be represented by a recursive definition When using a fractal to represent a physical object, some degree of randomness is usually added to make the image more realistic8groups that have broken dimensions so that each one looks like an exact copy of the second (like the Mandelbrot group in Mathematics); (In Computers) geometric shapes that have interesting contour lines9A geometric figure that repeats itself under several levels of magnification, a shape that appears irregular at all scales of length, e.g. a fern10A geometric figure, built up from a simple shape, by generating the same or similar changes on successively smaller scales; it shows self-similarity on all scalesSlide11
