** Video 2: "The Golden Mean" (week 8) **
a. What do you know about the golden mean? Its a number relevant in nature and science. b. What's the connection between the golden mean and mathematics? I think it has to do with maths, geometry and constants in nature. c. Mention five words you think you will listen to in the video. Geometry, Circle, Pi, Numbers, Golden.

 * II. While viewing and after viewing **

1. What's the process to construct the Fibonacci numbers? It's a very simple sequence of numbers starting with the number 1 twice, then the succeeding number is the sum of the two preceding ones.

2. Why are many things designed using the Fibonacci rectangle and spiral? Because they're aesthetically appealing for most people.

3. Mention some examples of the Fibonacci spiral in the world around us and inside us. The helixes in our DNA respect the same ratio of the Fibonacci numbers. The iPhone from Apple and Greece's Parthenon were designed with ratios that approximate the Golden Mean.

4. In your opinion what are the applications of the Fibonacci theories? It could have a thousand applications, for example, the sequence and the ratios could be tested to determine if it has a better use in architecture, or to make smarter computers. It could also have some use on other fields such as Mathematics, Physics, Mechanics, Computer Science and Chemistry.
