The Mandelbrot Set and Julia Sets

The Mandelbrot Set is Connected

As we have seen, the mandelbrot set is surrounded by small copies of itself.
Magnifications, such as those below, certainly suggest that the small copies of the Mandelbrot set are islands, well-separated from the main body of the set and from one another.
However, Douady and Hubbard proved the Mandelbrot set is connected.
That is, the intricately branched decorations are filled with strings of tiny Mandelbrot sets, invisible at this level of magnification, but all linked back to the main body of the set.
This is another lesson on the need to be careful when interpreting computer pictures.
