Today (11/23) is Fibonacci Day, honoring the mathematical sequence 1-1-2-3(-5-8-13-21-. . . ), where each term after the beginning is the sum of the preceding two terms. The Fibonacci numbers show up all over nature, as in the common counts of flower petals, the seeds in a sunflower, and the spiraling chambers of nautilus shells. Today's tie has several spirals in the G-clef, and it celebrates "nature" in the call for "all that has breath" to praise God. I chose it especially for this week of Thanksgiving celebrations, including a great dinner today at our church in Somerset.
