65 on May 24: WICN in Worcester's annual Bob Dylan Birthday Bash is live tonight at 7:30:

...Two RI based bands will come together in WICN's performance studio to celebrate the life and the music of the man. Fred Wilkes, Michele Wilson, Rich Sage and Kenny Johnson from Harmony roots rock band Five Of A Kind will join with Rick Bellaire, John Dunn and Vincent Pasternak of Providence based acoustic band Folks Together to perform the songs, and host Nick DiBiasio will read interesting facts about Bob Dylan's life and excerpts from his book "Chronicles, Vol 1."

The public radio station is at 90.5 FM and streams online.

DaVinci Code glossary: The aptly named Katherine Monk of CanWest publishes Forgotten your Fibonacci sequence? A film primer on the Montreal Gazette site.

Here's you'll find cilice, cryptex and my old favorite, the Fibonacci sequence. She doesn't quite get it, though (you can tell):

Fibonacci sequence: A progression of numbers in which the term is equal to the sum of the preceding two terms. In the book, we're given a Fibonacci sequence of 1-1-2-3-5-8-13-21, which is supposed to help our two heroes solve an important puzzle.

More: Plants that are formed in spirals, such as pinecones, pineapples and sunflowers, illustrate Fibonacci numbers. Many plants produce new branches in quantities that are based on Fibonacci numbers.

Fibonacci numbers in flower petals:
3 Lilies
5 Buttercups, Roses
8 Delphinium
13 Marigolds
21 Black-eyed susans
34 Pyrethrum
55/89 Daisies

We're talking the structure of nature here.

Fibonacci was actually Leonard of Pisa and in the 1200s he was watching rabbits reproduce...

Bonus: A stunningly beautiful sunflower photo.
