Quotes & Sayings About Convection

Carding's robe, for example, had become a silk and lace convection of overpoweringly expensive tastelessness, and gave him the appearance of a big red jelly draped with antimacassars.
'It suits me, don't you think? — Terry Pratchett

The fundamental reason why carbon dioxide in the atmosphere is critically important to biology is that there is so little of it. A field of corn growing in full sunlight in the middle of the day uses up all the carbon dioxide within a meter of the ground in about five minutes. If the air were not constantly stirred by convection currents and winds, the corn would stop growing. — Freeman Dyson

Ehric frowned as he peeled a Post-It note off the package. "Preheat to three seventy-five." His brother went to the wall ovens and began pushing buttons. "Convection?"
"Doesn't say."
"Damn it."
Under and other circumstances, Assail would have found it impossible to believe that Ecale was wasting his meager urge to speak on cooking. But Marisol and her grandmother had changed everything ... for the short time they had been here. — J.R. Ward

IF you remember every word in this book, your memory will have recorded about two million pieces of information: the order in your brain will have increased by about two million units. However, while you have been reading the book, you will have converted at least a thousand calories of ordered energy, in the form of food, into disordered energy, in the form of heat that you lose to the air around you by convection and sweat. This will increase the disorder of the universe by about twenty million million million million units - or about ten million million million times the increase in order in your brain - and that's if you remember everything in this book. — Stephen Hawking

It's really fun to have a convection oven, even it if it's a little convection toaster oven. It really changes the way you bake. — Tom Douglas

Touch me again, Bird Man, I thought urgently. Tell a joke, say anything -- because I was having the convection feeling. As if my skin were rippling, dissolving. Kiwi describes this phenomenon, "convection" {n}, in his Field Notes: the rapid cooling of a body in the absence of all tourists. Even Kiwi, King of Stage Fright, admitted to feeling it on Sunday nights. Convection caused your thoughts to develop an alarming blue tinge and required touch or speech with another human being as its antidote (Seths didn't work, not even my red Seth, I'd tried). Sweating could feel dangerous if you were alone in the swamp, as if droplet by droplet your body might get whisked into the sun. — Karen Russell

Three dominant hypotheses explain what drives plate tectonic motion. Each one relies on the convention of the mantle - the movement of heated rock materials beneath earth's crust - but each one focuses on a different piece of the cycle: Mantle convection hypothesis: This hypothesis proposes that heated materials inside the earth move up and down in a circular motion (like the wax in a lava lamp) and the continental plates resting on this mat-erial are moved in the direction of the circular motion. Ridge-push hypothesis: This hypothesis states that the creation of new rock materials along mid-ocean ridges continually pushes oceanic crustal plates upward and outward, so that the far edges are forced into collisions with other plates. Slab-pull hypothesis: This hypothesis is the opposite of the ridge-push model. It proposes that the heavy, dense outer edges of crustal plates sink into the mantle at plate boundaries and pull the rest of the plate along with them. — Alecia M. Spooner

And Lotto beamed with pleasure, preening, eyes darting around to see which kind soul in the room could have sent along the champagne, the force of his delight such that wherever his eyes landed, the recipients of the gaze would look up out of their food and conversation. and a startled expression would come over their face, a flush, and nearly everyone began grinning back, so that on this spangled early evening with the sun shining through the windows in gold streams, and the treetops rustling in the wind, and the streets full of congregating, relieved people, Lotto sparked upwellings of inexplicable glee in dozens of chests, lightening the already buoyant mood in one swift wave. Animal magnetism is real. It spreads through bodily convection. Even Ariel smiled back. The stunned grin stayed on the faces of some people, an expressions of speculation growing, hoping he would look at them again, or wondering who he was because on this day, and in this world, he was someone. — Lauren Groff

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. — Ian Tregillis
