Radon is a colorless, odorless, radioactive gas. It forms naturally from the decay (breaking down) of radioactive elements, such as uranium, which are found in different amounts in soil and rock throughout the world. Radon gas in the soil and rock can move into the air and into underground water and surface water. Radon is present outdoors and indoors.
The Mandelbrot set is the set of complex numbers for which the function () = + does not diverge when iterated from =, i.e., for which the sequence (), (()), etc., remains bounded in absolute value. A zoom sequence illustrating the set of complex numbers termed the Mandelbrot set. Its definition and name are due to Adrien Douady, in tribute to the mathematician Benoit Mandelbrot. The set is connected to a Julia set, and related Julia sets produce similarly complex fractal shapes.
