Practical fractals: there's probably one in your cell phone

Cellphones have to receive a variety of radio signals:
Bluetooth, GPS, WiFi, cell tower, etc. Fractal design
allows the fabrication of a versatile antenna that is very small.

AKSARBENT meant to watch 60 Minutes last night but got waylaid by NOVA's program about the discovery of fractal geometry by Benoit Mandelbrot.
     (Sometimes PBS cleverly pries AKSARBENT's eyeballs away from CBS on Sundays by dumbing science down and then walking it to us down that thin middlebrow line betwixt engrossing and inscrutable.)
     In case the only thing you know about fractals is that ubiquitous image on tie-dyed tee shirts, it is defined thusly according to WikiPedia:

A rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole," a property called self-similarity.

Anyway, trees are supposedly illustrative of fractal design because of their recursive branch structure.

This explains a lot! The reason AKSARBENT's reception of NOVA was so lousy was that the damn tree outside was stealing our free HD signal.

We need a fractal TELEVISION antenna to defeat the thieving Maple or Elm or whatever it is outside that is helping itself to our digital diversions.

Or a chain saw. Can you hear me now, stumpy?
