Convection Current Quotes

Examples of such self-reorganization abound in Order Out of Chaos. Heat moving evenly through a liquid suddenly, at a certain threshold, converts into a convection current that radically reorganizes the liquid, and millions of molecules, as if on cue, suddenly form themselves into hexagonal cells.

The assumption is that the convecting fluids in the Earth act somehow like the currents in wires. Exactly what happens isn’t known, but it is felt pretty certain that it is connected with the core spinning and with its being liquid. Bodies that don’t have a liquid core—the Moon and Mars, for instance—don’t have magnetism.

The Tull-Toks claim that everything in the universe can be read. Each star is a living text, where the massive convection currents of superheated gas tell an epic drama, with the starspots serving as punctuation, the coronal loops extended figures of speech, and the flares emphatic passages that ring true in the deep silence of cold space. Each planet contains a poem, written out in the bleak, jagged, staccato rhythm of bare rocky cores or the lyrical, lingering, rich rhymes—both masculine and feminine—of swirling gas giants. And then there are the planets with life, constructed like intricate jeweled clockwork, containing a multitude of self-referential literary devices that echo and re-echo without end.

Funny thing about Gabby: you wouldn’t know it from looking at him, with his golden halo and platonic beauty, but the guy was something of a pack rat. He’d been collecting little odds and ends since at least the double-digit redshifts. The interior reality of Gabriel’s Magisterium burbled and shifted like convection currents in a star on the zaftig end of the main sequence. Because, I realized, that’s what they were. Dull dim light, from IR to X-ray, oozed past me like the wax in a million-mile lava lamp while carbon, nitrogen, and oxygen nuclei did little do-si-dos about my toes. Every bubble, every sizzle, every new nucleus, every photodissociation tagged something of interest to Gabriel. The heart of this star smelled of roses and musty libraries.

I was standing lost, sunk, my hands in my pockets, gazing toward Tinker Mountain and feeling the earth reel down. All at once, I saw what looked like a Martian spaceship whirling towards me in the air. It flashed borrowed light like a propeller. Its forward motion greatly outran its fall. As I watched, transfixed, it rose, just before it would have touched a thistle, and hovered pirouetting in one spot, then twirled on and finally came to rest. I found it in the grass; it was a maple key…Hullo. I threw it into the wind and it flew off again, bristling with animate purpose, not like a thing dropped or windblown, pushed by the witless winds of convection currents hauling round the world’s rondure where they must, but like a creature muscled and vigorous, or a creature spread thin to that other wind, the wind of the spirit that bloweth where it listeth, lighting, and raising up, and easing down. O maple key, I thought, I must confess I thought, o welcome, cheers. And the bell under my ribs rang a true note, a flourish of blended horns, clarion, sweet, and making a long dim sense I will try at length to explain. Flung is too harsh a word for the rush of the world. Blown is more like it, but blown by a generous, unending breath. That breath never ceases to kindle, exuberant, abandoned; frayed splinters spatter in every direction and burgeon into flame. And now when I sway to a fitful wind, alone and listing, I will think, maple key. When I see a photograph of earth from outer space, the planet so startlingly painterly and hung, I will think, maple key. When I shake your hand or meet your eyes, I will think two maple keys. If I am maple key falling, at least I can twirl. Thomas Merton wrote, “There is always a temptation to diddle around in the contemplative life, making itsy-bitsy statues.” There is always an enormous temptation in all of life to diddle around making itsy-bitsy friends and meals and journeys for itsy-bitsy years on end. It’s no self-conscious, so apparently moral, simple to step aside from the gaps where the creeks and winds pour down, saying, I never merited this grace, quite rightly, and then to sulk along the rest of your days on the edge of rage. I won’t have it. The world is wilder than that in all directions, more dangerous and bitter, more extravagant and bright. We are making hay when we should be making whoopee; we are raising tomatoes when we should be raising Cain, or Lazarus. Ezekiel excoriates false prophets who have “not gone up into the gaps.” The gaps are the thing. The gaps are the spirit’s one home, the altitudes and latitudes so dazzlingly spare and clean that the spirit can discover itself for the first time like a once blind man unbound. The gaps are the cliffs in the rock where you cower to see the back parts of God; they are the fissures between mountains and cells the wind lances through, the icy narrowing fjords splitting the cliffs of mystery. Go up into the gaps. If you can find them; they shift and vanish too. Stalk the gaps. Squeak into a gap in the soil, turn, and unlock- more than a maple- a universe. This is how you spend the afternoon, and tomorrow morning, and tomorrow afternoon. Spend the afternoon. You can’t take it with you.

She also discovered that he was attracted by the dreadful, among the galactic wares cramming the narrow shops into which they ducked. He actually appeared to seriously consider for several minutes what was claimed to be a genuine twentieth-century reproduction lamp, of Jacksonian manufacture, consisting of a sealed glass vessel containing two immiscible liquids which slowly rose and fell in the convection currents. “It looks just like red blood corpuscles floating in plasma,” Vorkosigan opined, staring in fascination at the under-lit blobs. “But as a wedding present?” she choked, half amused, half appalled. “What kind of message would people take it for?” “It would make Gregor laugh,” he replied. “Not a gift he gets much. But you’re right, the wedding present proper needs to be, er, proper. Public and political, not personal.” With a regretful sigh, he returned the lamp to its shelf. After another moment, he changed his mind again, bought it, and had it shipped. “I’ll get him another present for the wedding. This can be for his birthday.” After
