Fibonacci Mischief Mis-Managed.

Ah, Fibonacci Day. The one day of the year when mathematicians smile mysteriously and everyone else stares at a sequence of numbers as if it contains the location of Atlantis.

Nov. 23: Fibonacci Day

I love puzzles...and thanks to the Dan Brown series of books and amazing puzzles...I learned about the Fibonacci sequence.

Definition

A series of numbers where each term equals the sum of the two preceding terms, starting with 0 and 1, producing values such as 0, 1, 1, 2, 3, 5, 8, 13, and so on.

The sequence is defined by the recurrence relation:

• F₀ = 0, F₁ = 1

• Fₙ = Fₙ₋₁ + Fₙ₋₂ for n > 1 (what?)

Ummmmm! OK...I hope you got that!

First Several Terms

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 … Math is Fun...Right? 🤒🤒🤒

Honestly, Fibonacci seems like the sort of sequence that was invented by a wizard who got tired of dragons.

🤒🤒🤒

Student:

"Master, how many rabbits shall we have for stew next month?"

Master:

"Add the previous two months, Grasshopper."

Student:

"And after that?"

Master:

"Add the previous two months."

Student:

"And after that?"

Master:

"Still the previous two, Grasshopper".

Student:

"Master, that's absurd."

Master:

"Exactly. Write it down. Future mathematicians will call it elegant."

.....I suspect that most mathematical discoveries happened like this...don't you:

1. A curious person notices a pattern.

2. They spend ten years proving it.

3. They publish a paper.

4. The pattern immediately appears in pinecones, seashells, hurricanes, sunflowers, galaxies, and the arrangement of socks in the laundry.

Everyone nods wisely as if this was obvious.

Meanwhile, somewhere in a parallel universe:

Fibonacci's Cat sits on a windowsill.

Day 1: One cat.

Day 2: One cat.

Day 3: Two cats.

Day 4: Three cats.

Day 5: Five cats.

Day 6: Eight cats.

Day 7: Twenty-seven lawyers, a clown, and a small brass tuba band.

Nobody knows where in day 7 the sequence went wrong, but the cat insists the mathematics is sound. It trusts Fibonacci completely.

Then it writes a poem based on the Fib form popularized by Gregory K. Pincus, where syllables follow the Fibonacci sequence: 1, 1, 2, 3, 5, 8....

One
Cat.
Two purrs,
Three tails-swish,
Five paws midnight claws,
Eight bright eyes silly mischief plots.

I'm delighted if the crazy story gave you a laugh, as we wander into the sort of wonderful territory where mathematics, mystical numbers and nonsense shake hands and agree to confuse everyone equally. 😄

Happy Fibonacci Day, my friends. May your numbers add up, your coffee remain plentiful, and your zucchini contain only the expected number of zucchinis seeds. 😄🥒☕📚
