Fractals are quite the interesting topic! Hunting the Hidden Dimension is a program on Nova (PBS) about the concept of fractals and the potential implications. The basic idea is that apparently there is some sort of mathematical way to characterize the seeming chaos of the natural world.
Many people of faith (i.e. Christians) are quite likely to be thinking that this sort of discovered order within the seeming chaos is evidence of “a mind” behind that structure. For how could a random and chance universe produce such symmetry and similarity throughout the known universe?
