Individual Research Projects Section 7.6

Project 7.6

Do some research on the length-to-width ratios of the packaging of common household items. Form some conclusions. Find some examples of the golden ratio in art. Do some research on dynamic symmetry.

Project 7.7

In Example 2 Section 7.6, we assumed the width of the Parthenon to be 101 ft and found the height to be 62.4 (assuming the golden ratio). If you worked Problem 8, you assumed the height to be 60 ft and found the width using the golden ratio to be 97 ft. Are the numbers from Example 2 and from Problem 11 consistent? Can you draw any conclusions?

Project 7.10

Is there a “best” rectangle. If you like to do origami, which size paper best suits your needs? What are “standard” sizes for paper?

Project 7.11

The discovery and acceptance of non-Euclidean geometries had an impact on all of our thinking about the nature of scientific truth. Can we ever know truth in general? Write a paper on the nature of scientific laws, the nature of an axiomatic system, and the implications of non-Euclidean geometries.

Project 7.12

Find the one composite number in the following set:
