Day 09: Heart of Mathematics

Last time: More on Fibonacci numbers, and the golden ratio. Coneflowers, and more pine cones. Looking at various quantities constructed from the Fibonacci numbers in the limit as the Fibonacci numbers tended to infinity.
Today:
- Assignment 1 will be due on Friday (the Thirteenth).
- Project Assignment 1: by Friday, 9/20, pick your partner(s) (you can go alone!) for the poster project; it would also be nice if you have a topic, but that's not required!
- In preparation for Fibonacci Nim, let's look at some of the homework:
  - I.17
  - I.19 (what were your experiences?)
- Creating natural numbers as sums of Fibonacci numbers (good preparation for your assignment #1): Discuss III.1 and III.2
- Competitive Nim: The game of Fibonacci Nim (modified on-line version)
Next time: Prime Numbers (realizing that it's 9/11....)
