			<content:encoded><![CDATA[<p>A small, straight twig, held steady between the spokes of a rotating bicycle wheel as it speeds up, slows down, speeds up, slows down, falls still, and then is set to spinning again. </p>
<p>The last gasps of an aerosol can, shaken and sprayed by a determined hand, liquid and air shunted out together through a tiny hole in ragged, pulsating bursts until nothing more remains to be ejected.</p>
<p>A wind-up car that you turn with a key, released at its tautest on a table and allowed to travel as far as it will go, the key in its back clicking down in lengthening ticks its brief, meandering adventure.  </p>
<p>The world&#8217;s most precise drummer gently sweeping a metal brush back and forth, back and forth, back and forth across his snare, in a lull between the blare of the saxophone and the whalesong of the bass. His hand moves so fast you can hardly believe it, a blur to look at; but he slows. He stops. Gives over his gentle solo.</p>
<p>A bullet-shaped UFO, lights wavering, hovering in the dead silence of the night&mdash;approaching its landing spot, cutting its engine, and gliding to rest before my disbelieving eyes.</p>
<p>Superstrings, vibrating with the precise harmonics required to create the fundamental material constituents of our universe and all that it contains. </p>
<p>Sand slipping through an hourglass, each grain squeaking against the sides of that narrow channel before falling, with the clink of a coin, into the bottom chamber. </p>
<p>A stream of water dripped onto a hot stove. Sizzling. Silence. Water into air.</p>
<p>Summer.</p>

			<content:encoded><![CDATA[<blockquote><p>The so-called goat-sucker lives on mountains; it is a little larger than the owsel, and less than the cuckoo; it lays two eggs, or three at the most, and is of a sluggish disposition. It flies up to the she-goat and sucks its milk, from which habit it derives its name; it is said that, after it has sucked the teat of the animal, the teat dries up and the animal goes blind. It is dim-sighted in the day-time, but sees well enough by night. </p>
<p><strong>&mdash;Aristotle, &#8220;The History of Animals,&#8221; c. 350 B.C.</strong>
</p></blockquote>
<p>The Whip-poor-will is a bird of many distinctions. </p>
<p>For one, it has a marvelously ridiculous common name, supposedly derived from its insistent three-note <a href="http://www.allaboutbirds.org/guide/Whip-poor-will/sounds">call</a>, which resounds through the forests of the eastern United States all through the night. (Listen to that recording, will you? As you know, I adore birders namers of birds, but transliterating the exquisitely alien trills and whistles of birdsong into syllables we can spell and pronounce does little but highlight the paucity of human language when compared to its avian counterpart.) </p>
<p>The Whip-poor-will also has a marvelously eerie scientific name: <em>Caprimulgus vociferus</em>, literally &#8220;noisy goatsucker.&#8221; Unlike the mythic <a href="http://en.wikipedia.org/wiki/Chupacabra">Chupacabra</a>, birds of the genus <i>Caprimulgus</i>, to which the <a href="http://www.allaboutbirds.org/guide/Common_Nighthawk/lifehistory">common nighthawk</a> also belongs, were not believed to drain the blood of goats, but to drink their milk instead. This is, if you ask me, a more palatable proposition: but it is equally fictitious. Aristotle himself&mdash;an august thinker, to be sure, but <a href="http://bmcr.brynmawr.edu/2004/2004-09-19.html">wrong</a> about so very many things&mdash;thought this to be true. </p>
<p>The story may have arisen because of the birds&#8217; incredibly wide bills, which apparently looked to ancient observers as if they would be very useful for sucking at goat teats. In fact, what those bills <em>are</em> suited for is gaping open in flight and snatching up large insects, which are what make up the majority of the <i>Caprimulgus</i> diet.</p>
<p>In sum, the Whip-poor-will is a medium-sized, ground-nesting, nocturnal bird with beautiful mottled plumage consisting of a complex pattern of browns, grays, blacks, and whites: a confusion of earthy colors that makes it almost invisible when still. And it is very, very beautiful.</p>
<p>I can tell you quite confidently just how soft that pretty plumage is&mdash;it is as downy as an owl&#8217;s&mdash;because I spent an hour and a half skinning a lovely little female Whip-poor-will this morning in the Field Museum&#8217;s bird prep lab. The number on her tag began with the initials &#8220;FC,&#8221; which means she was collected as a wounded bird by the <a href="http://www.flintcreekwildlife.org/">Flint Creek Wildlife Rehabilitation Center</a> in Northerly Island, Chicago, and unfortunately didn&#8217;t make it. In fact, as I was handling her I noticed that her right humerus was broken, probably the injury that brought her to Flint Creek.</p>
<p>Here she is. Dave, the collections manager in the Bird Division, was very happy to have her as a study skin; I don&#8217;t think we see too many Whips in the lab.</p>

			<content:encoded><![CDATA[<p>When the sunset shares space with the waxing moon, follow a curve-billed thrasher&#8217;s crazy mimetic call&mdash;all whistle, click, and buzz, with no beginning and no end&mdash;up the rocky side of Hayden Butte in Tempe, Arizona. He will be sitting, alone like you, on the edge of an overhead line, and he will not be disturbed. </p>
<p>If you stand just underneath his beak&mdash;but just&mdash;his notes will fall into your hair and trickle over your upturned face like the water that ran down your naked skin in the morning. You are grubby with the heat of the day and the breath of strangers, and the thrasher&#8217;s song is a shower. </p>
<p>It does not matter how you look, standing there with your arms out and your eyes closed and the thrasher singing you clean, because listen, my friend. Who is he really going to tell? </p>

			<content:encoded><![CDATA[<p>There has always been, for me, something shivery and mysterious about the Book of the <a href="http://www.amazon.com/gp/product/0140442898?ie=UTF8&#038;tag=thescieessa-20&#038;linkCode=as2&#038;camp=1789&#038;creative=390957&#038;creativeASIN=0140442898">Thousand and One Nights</a><img src="http://www.assoc-amazon.com/e/ir?t=thescieessa-20&#038;l=as2&#038;o=1&#038;a=0140442898" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;" />. One reason is that although for years it sat quite within reach on my father&#8217;s bookshelf, both the Nights and its store of what we so (in)delicately call &#8220;adult&#8221; material were closed to me as a child: locked tight with a single shake of a maternal head. (Let me tell you that when I read the stories, in direct defiance of that fiat, and discovered that not only is there a lot of sex in them but that the very first tale is about a fart so legendary it reverberates through an entire kingdom for generations, I laughed until I cried. Adult indeed.) </p>
<p>But far more wonderful, what I knew about the comparatively slim volume revealed its position within that most favored of literary genres: the infinite book. That &#8220;thousand and one!&#8221; How I craved its everlasting promise of still one more night after you thought the final one had come. </p>
<p>One other thing gave the Thousand and One Nights limitless mystery, and that was the fact that it held stories within stories within stories. Scheherazade would begin to tell a tale, and all of a sudden its narrator would begin to tell his own tale, and before you knew it <i>its</i> narrator was holding forth on yet another narrative, and so on and so forth until your head spun with delicious confusion. No matter where you looked, it seemed, there was a tiny reflection of the book as a whole, which in turn contained its own reflection, which contained&#8230;and in turn&#8230;and in turn&#8230; The book of Nights was made of endless versions of itself, writ small (<font size="-1">er</font size> <font size="-2">and smaller</font size> <font size="-3">and smaller</font size>). </p>
<p>As in the Nights, so in Nature. Self-similarity is everywhere. Each stretch of the British coastline, <a href="http://www.sciencemag.org/cgi/content/abstract/sci;156/3775/636"> fractal-father Mandelbrot</a> tells us, curves and jags and undulates in such a way as to produce a remarkably faithful scale model (not perfect, but close) of the coastline as a whole, no matter how many times you carve it up into smaller and smaller pieces. Always you will find that each individual part contains within itself a rough unabridged copy of the total sum. </p>
<p>So again with the leaves of a <a href="http://www.scienceessayist.com/2009/07/07/persistence-fern/">fern</a>, whose fronds divide into fronds that divide into fronds, and with the branching bronchial tubes of the lungs, which fork and fork and fork once more. Raise your head to the skies and there too the part reflects the whole. Galaxies clump into small groups, like little knots of gossiping schoolchildren; those clumps form larger clusters, and those clusters even larger throngs. </p>
<p>(What is it for, all this huddling? Is it a lonely thing, being a galaxy? I can&#8217;t imagine it could be, since you yourself are made up of clustered clustered clusters of stars&#8230;)</p>
<p>And what does all this have to do with New Year&#8217;s Day, my dear dears? Why, only this: When I woke up this morning I resolved to make my own self-similarity. This first day, I decided&mdash;itself just one small part of the long annum stretching out before me in all its promise and disappointment&mdash;should be a scale model, crafted as best I can, of what I want the year to be like. </p>
<p>Therefore, this is what today contained: </p>
<p>Waking to sunlight through curtains and a cat on my belly. </p>
<p>Cooking, with Ross and for a friend. Eating what I had made. Laughing.</p>
<p>Walking, face tingling in the January (!) cold. Looking. Breathing. Hugging Ross.</p>
<p>Making <a href="http://www.flickr.com/photos/goddessparkle/4235121978/">what I know</a> how to make. </p>
<p>Sitting, just sitting, while <a href="http://en.wikipedia.org/wiki/Symphony_No._9_%28Dvo%C5%99%C3%A1k%29">music</a> plays. <a href="http://www.amazon.com/gp/product/0425188604?ie=UTF8&#038;tag=thescieessa-20&#038;linkCode=as2&#038;camp=1789&#038;creative=390957&#038;creativeASIN=0425188604">Reading</a><img src="http://www.assoc-amazon.com/e/ir?t=thescieessa-20&#038;l=as2&#038;o=1&#038;a=0425188604" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;" /> with a cup of coffee by my side.</p>
<p>Finally, perhaps most importantly of all, writing this for both you and myself, with a calm heart and nothing to prove. </p>
<p>Welcome to a new decade, readers-mine. I&#8217;m enjoying it so far. I&#8217;m imagining, at least for one day, that I know what the future holds. It holds a thousand and one New Year&#8217;s Days.</p>
