(The following problem is problem 4.22 of Chapman's textbook,
 p. 184)

Bacterial Growth. Suppose that a biologist performs 
an experiment in which he or she measures the rate at which
a specific type of bacterium reproduces asexually in
different culture media. The experiment shows that in Medium A
the bacteria reproduce once every 60 minutes, and in Medium B
the bacteria reproduce once every 90 minutes. Assume that a
single bacterium is placed on each culture medium at the
beginning of the experiment. Write a program that calculates
and plots the number of bacteria present in each culture at
intervals of 3 hours from the beginning of the experiment
until 24 hours have elapsed. Make two plots, one a linear xy
plot and the other a linear-log (semilogy) plot. How do the
numbers of bacteria compare on the two media after 24 hours?
