Fractal Geometry discussed on Nova

Fractal Mechanisms in Neural Control

Heartbeats, optics, body motion, blood flow, fractals everywhere!
Biological functions ruled by mathematical fractals.

Maybe stocks? :lol:

Did you know that cell phones use Fractal Antennas?

"A fractal antenna's response differs markedly from traditional antenna designs, in that it is capable of operating with good-to-excellent performance at many different frequencies simultaneously. Normally standard antennas have to be "cut" for the frequency for which they are to be used—and thus the standard antennas only work well at that frequency. This makes the fractal antenna an excellent design for wideband and multiband applications."

When Nathan "Chip" Cohen, N1IR, built the first fractal antenna, his mind was not on the future of telecommunications antennas. In 1988, Chip had a 'no antenna clause' at his Boston apartment. To assure good 2 Meter repeater connections, he used an intricate fractal shape. The fractal's pattern, repeating on many size scales, acted to self-load the antenna. It provided a good 50 ohm match and could hit repeaters well into New Hampshire.
Fractal antennas pose a few surprises. First, they have a tendency to be very broadband or multiband. Second, they can shrink the size down without coils or capacitors and are very efficient.
