I love having a daughter-in-law who says, "Hey! Your avatar had a haircut!"
She also wrote a lullaby using the Fibonacci Sequence. I told her thanks a lot because now I'll have to sing that with Brendan and can only go to 21 without having to think too much. I printed it out, so I'll be prepared because he'll learn it by the time he spends the night again. Check it out if you want down there on the right in Perky Skeptic. We did some problem-solving activities using Fibonacci numbers when I taught in the gifted program that were fun. No, really!
The above cartoon (Amend 2005) shows an unconventional sports application of the Fibonacci numbers (left two panels). (The right panel instead applies the Perrin sequence).
I have no clue what the Perrin sequence is.
In the Fibonacci number sequence, the first number of the sequence is 0, the second number is 1, and each subsequent number is equal to the sum of the previous two numbers of the sequence itself, yielding the sequence 0, 1, 1, 2, 3, 5, 8, etc. This way: 0 + 1 = 1, 1 + 1 = 2, 1 + 2 = 3, etc.
This sequence is found in nature (pine cones, sunflowers, bees) and relates to the Golden Ratio and Pascal's Triangle. Don't even ask! I sort of knew this at one time, but just remembering the sequence is all I can do now.
