There Is No Word A Poem by Tony Hoagland www.poetryfoundation.org what I already am thinking about is my gratitude for language— how it will stretch just so much and no farther; how there are some holes it will not cover up; how it will move, if not inside, then around the circumference of almost anything— how, over the years, it has given me back all the hours and days, all the plodding love and faith, all the misunderstandings and secrets I have willingly poured into it. languagewords
Trees and graphs Show image 0 Show image 1 A tree is a kind of graph, but a graph can be considerably more complex than a tree. I have reason to believe, which for brevity’s sake I will treat elsewhere, that the most complex class of processes and structures we humans can consciously prescribe, reduces mathematically to a tree. A tree has a top, bottom, left and right. Its branches fan out from the trunk and they don’t intersect with one another. They are discrete, contiguous, identifiable objects which persist across time. Trees are Things. Software and websites, however, reduce to arbitrarily more complex structures: they are graphs. A graph has no meaningful orientation whatsoever. No sequence, no obvious start or end—at least none that we can intuit. It is better considered not as one Thing, but as a federation of Things, like the brain or a fungus network, or perhaps a composite artifact left behind from an ongoing process, like an ant colony or human city.
