What are fractals
What are fractals?

A fractal is a pattern that is self-similar. When magnified, small parts of a self-similar figure cannot be distinguished from the whole figure.


Benoit mandelbrot
Benoit Mandelbrot

Benoit Mandelbrot was born in 1924 in Warsaw and moved to the US in 1958. He is known as the “father of fractals. He is a mathematics professor and researcher. He made many important discoveries in the field of fractals during the 1970’s and 1980’s. In 1982 he connected mathematics and nature through fractal geometry.


Fractals in nature
Fractals in Nature

Some natural objects that approximate fractals include:

Clouds

Mountain ranges

Lightning bolts

Snowflakes

Broccoli & cauliflower

Crystals

Trees and ferns


Waclaw sierpinski 1882 1969
Waclaw Sierpinski1882-1969

Waclaw Sierpinski was born in 1882 in Warsaw, Poland. He was a professor of mathematics at the University of Lvov, the University of Moscow, and the University of Warsaw. He invented the Sierpinski Gasket.
