What do movie special effects, the stock market, heart attacks, and the rings of Saturn have in common? They all consist of fractals, irregular repeating shapes that are found in cloud formations and tree limbs, in stalks of broccoli and craggy mountain ranges, and even in the rhythm of the human heart. NOVA takes viewers on a fascinating quest with a group of pioneering mathematicians determined to decipher the rules that govern fractal geometry. Their remarkable findings are deepening our understanding of nature and stimulating a new wave of scientific, medical and artistic innovation stretching from the ecology of the rainforest to fashion design. Special DVD features include: materials and activities for educators; a link to the NOVA Web site; scene selections; closed captions; and described video for the visually impaired. On one DVD5 disc.
