Later on, mathematicians took up the much more difficult question, can we find a formula for rk(n), the number of ways to express n as a sum of k integral squares? This last question led to some of the most sophisticated mathematics of the 20th century, as did a common generalization of all these questions...Hidden Symmetries of Labyrinths from Antiquity and the Middle Ages

Rather than try to show the huge range of ways that mathematics is assisting biologists in understanding the vast landscape of modern biology, I will take a look at a rather small domain, which offers ways to look at some traditional topics from a novel point of view...
