Nobody. Fractals are not owned by anyone!
But to a mathematician, it is a neat, neat subject area. Why are fractals important? Fractals help us study and understand important scientific concepts, such as the way bacteria grow, patterns in freezing water (snowflakes) and brain waves, for example. Their formulas have made possible many scientific breakthroughs.
Self-similarity.
Complex mathmatic equations.
Fractals are situations where the geometry seems best approximated by an infinitely "branching" sequence - used, for example, in modeling trees. For work on fractals that I have done as a theoretician, I recommend the included links. I just happen to have an original answer, and I want to make it known.
Fractals were discovered in 1975 by a scientist names Benoit Mandelbrot.
Discovered
Fractals
Benoit Mandelbrot is the man who is usually credited to have discovered fractals in the year 1975. He was the first person to use this word and was also the first man to represent them in visual form. But history also shows that some facts about fractals were known to mathematicians as early as the 17th century.
Pi is a number. There are no fractals of pi.
Crystals are usually not fractals.
Nobody. Fractals are not owned by anyone!
The Beauty of Fractals was created in 1986.
Some common techniques for generating fractals would be to use iterated function systems, strange attractors, escape-time fractals, and random fractals.
There are infinitely many fractals so no list can exist.
Fractals are used for computer generated terrains.
By their very nature fractals are infinite in extent.
