## Poet’s Day, mathematically speaking

Today is ** Poet’s Day**, a day to celebrate the sensitive souls who, through the ages, shared their deepest thoughts through verse and rhyme. I have to admit to being more of a

*‘prose person’*than a

*‘poetry person’*, but that by no means implies that I don’t have the greatest respect and admiration for a good poem – it’s simply not my very favourite literary form.

Of course there’s a close relation between poetry and mathematics – a subject that is close to my heart. It was Einstein who said: *“Pure mathematics is, in its way, the poetry of logical ideas.”*

Mathematics in general seem to play an important role in poetry. Not only is there mathematics in the structure and rhythm of poetry, but many poems have also been written that contain overt mathematical themes. In a 2010 article entitled *“Poetry Inspired by Mathematics“*, Sara Glaz from the University of Connecticut, discusses some examples of such poems. More examples can be found in an earlier article from 2006 by JoAnne Growney, *“Mathematics in Poetry“*. In the latter article, Growney elegantly states, *“As mathematicians smile with delight at an elegant proof, others may be enchanted by the grace of a poem. An idea or an image expressed in just the right language–so that it could not be said better–is a treasure to which readers return.”*

An interesting new poetic form which I’ve discovered while doing some background reading for today, is the so-called * “Fibonacci poetry”*, which is based on the Fibonacci number sequence. Fibonacci numbers are a sequence, starting with 0 and 1, where each subsequent number is the sum of the previous two, i.e. 0,1,1,2,3,5,8,13,21,34,…

Fibonacci numbers occur often in nature, as I’ve discussed in an earlier blog post.

In poetry, the number sequence can refer to the numbers of letters, syllables or words in successive lines of the poem. These poems, known as *‘Fibs’*, are six lines long, typically starting with a single letter/syllable/word in the first line. They can, however, theoretically start with any number of letters/syllables/words in the Fibonacci sequence.

Even though this form, originally introduced by Gregory K in a blog post on the GottaBook blog, appears to still be more popular among mathematicians than among poets, it has managed to garner a mention in the New York Times Books section. Their example, based on syllables, neatly illustrate the concept:

*Blogs *

*spread *

*gossip *

*and rumor *

*But how about a *

*Rare, geeky form of poetry?*

I like the idea, I really do – very cool indeed! So, without further ado, herewith my own humble Fib for the day:

*Words*

*and*

*numbers*

*sequences*

*not just in nature*

*but warming the hearts of poets too.*

*(uhm, assuming ‘poets’ is a single syllable word, of course…)*

Happy Poet’s Day, everyone! And please do share some Fibs, if you’re that way inclined!
