Q4.28: There are many naturally occuring fractals. Read the following
list of objects and give reasons for why each is (or is not) a fractal.
Q4.28: You have just discovered how a random walker
can be used to grow spidery patterns similar to those
found in nature. Does this mean that random processes
are actually involved in forming these objects in nature?
Or are lightning, nerve cells, termite tunnels, and
electrodeposition patterns formed by totally different
processes, processes that have nothing to do with random
Q4.28: The discovery that a random walker can be used
to grow spidery patterns similar to structures found
in nature is very important to scientists. Why do you
think this discovery is important? In what ways could
this discovery prove to be useful?
Q4.28: Write a brief statement predicting the value
of the fractal dimension of the patterns that result
under each of the following conditions and giving the
reasons for your prediction:
(a) inject air into glycerol
(b) inject water at higher pressure into glycerol
(c) inject a 50-50 mix of water and glycerol into
