Chapter 5; The Cannon
Honors chem students. Please read pages 120-136 in The Cannon for Tuesday. In preparation for our discussion, post a comment on this post that includes a thought-provoking quote from this section of reading.
"Bear in mind that each one of these crystals is an ensemble of a billion billion chlorine and sodium ions, more atoms per granule than ther are stars in the Milky Way." (129)
"Chemistry is the core science, the central science, yet its contributions are often overlooked, including by many biologists, physicists, medical researchers, and others who should know better." (122)
"In theory, he said, all the material needed to construct any device imaginable...is already there, somewhere in the periodic table... 'If every person on the planet were a materials chemist,'...'it would still take a millennium or longer to understand the period table well enough to make all the things we want to make.'"
"Pretend this is a match," he said of the sticklet, and I nodded. "This," he said, lifting the sticklet over his desck, "is physics." He let the stick drop on his desk. Plink. "And this," he said, scaping the sticks virtual phosphor on a virtual matchbook cupped in his hand, "is chemistry."
"Chemistry is the core science, the central science, yet its contributions are often overlooked, including by many biologists, physicists, medical researchers, and others who should know better." (122)
"As a rule, elements are more stable and less chemically reactive when they're in a bonded relationship than when they're out of one,m for the same reason that married people are celebrated as society's source of levelheaded bourgeois dependability" (Pg 126).
"Whatever your chemical demand, whatever shape, size, or attribute your molecule must possess, chances are you'll find it somewhere in the well-stocked toy box that is our Goldilocks world--if not prefabricated naturally, then conjured in a laboratory." (pg. 124)
"And as in sleep or art, it is not always clear who is the dreamer, who is the dream. "My field is material chemistry, and one thing we don't admit to young students is how clueless we really are," said Frank DiSalvo... in theory, he said, all the material needed to construct any device imaginable, a warp drive, a transporter, the perfect toupee, is already there, somewhere in the periodic table." (pg 124)
'On Earth, under our conditions, we have lots of chemistry. We have temperature conditions where molecules can exist in three different states, as solid, liquid, or gas, and where, whith the input of energy, from the light of the sun or the heat of a fire, those molecules can change into other molecuels..." (123)
"When you are married, your coupling capacity is more or less filled, and you are considered "'taken.'" Not for nothing is the emblem of marriage, the wedding ring, a closed circle. Similarly for chemical partners in bondage: their reactive parts are already busy and so are unavailable for other relations." (126)
"The type of bond that links together atoms in a molecule, or one molecule to another, explains why the carbon lattices of a diamond are hard enough to be a girl's best friend forever.." (Pg. 125)
"From the 115 elements you can build a near infinity of molecules, of any type you need, to get all the structural and functional diversity you can ask for. There are at least 100,000 different molecules in the human body."
"On Earth, under our conditions, we have lots of chemistry. We have temperature conditions where molecules can exist in three different states, as solid, liquid, or gas, and where, with input of energy, from the light of the sun or the heat of a fire, those molecules can change into other molecules, into other complex assemblages of atoms."

"What happens when you put a whole lot of polarized Mickey Mouses together in one place-- like, say, Lake Michigan? The chins of one molecule are drawn gently toward the ears of another, lending water an overall shape and integrity that make Mickey quite mighty."
"One species' waste is anothers' preffered taste, however. Plants blend the carbon dioxide together with water to synthesize sugars- and generate as a lucky byproduct the oxygen we need." (136)
"We're not a heck of a lot different than the carbon based fiber in a steel-belted radial tire, so maybe we shouldn't take ourselves too seriously" pg. 1221
"Life is also a mix of endothermic and exothermic reactions, of gathering fuel and kindling, stacking the pieces with Boy Scout precision, striking the match, and feeling the burn. The body, after all, cannot afford to wait for the right chemistry to just happen."
"Chemistry is molecules. We are molecules.Chemisty is a truly anthropic science" (Pg. 123)
