Questions on African Fractals ch 7-8


1)     pp. 86-87 Compare the iterative properties of the positive integers (“counting numbers”) with that of the triangular numbers. Why does this matter for the African game tarumbeta?

2)     pp. 87-98 What evidence suggests that ancient Egyptians independently invented the Fibonacci sequence? What similarity can you find between the role of the altar in Karnak’s architecture and the altars in figure 2.3 and 2.4?

3)     pp. 89-90 What is the doubling sequence, and where do we find it in African cultural practices?

4)     pp. 90-93 Explain the significance of the doubling sequence in Shango.

5)     Pp. 93-96  What is Bamana sand divination? What is its mathematical significance?

6)     p. 98 How could you implement Bamana sand divination in hardware?

7)     pp. 99-100 What suggests that the Bamana technique originated in Africa? What was its significance in Europe?

8)     pp. 101-102 Explain the “marching formation” in Owari.

9)     pp. 103-105 Explain cellular automata.

22)Pp. 134-135 Besides the Dogon, what other recursive religions do we see in north Africa?

23)Pp. 137-138 What is the difference between drawing the Dogon pot stack by iteration versus self-reference? Can we be certain which program reflects the Dogon point of view?

24)Pp. 137-140 What examples of self-reference can we find in Africa?
