This
collection of short stories by Stan Rice,
who is also the author of nonfiction books of popular science and science
novels, takes the reader to the frontier between science and worlds of the
impossible (see his author website here). Readers of my science blog will appreciate the
creative telling of scientifically impossible stories; readers of my religion
blog will appreciate the question of whether, even if these things were
possible, would they be good?
The
stories in this collection are The Man Who Could Work Miracles, Light
Apparel, Flow of Blood, Wisdom Builds Her House, Rock
Bunnies, Entropy, Olga the Science Cat, Doghouse (all reviewed
earlier), and Fresh Air (reviewed here).
This
final story, Fresh Air, is the chemistry class you wish you had, the
world (the whole world) as told from the viewpoint of an oxygen atom named
Gould. Gould, who resembles a white man, is inherently selfish. He has a hunger
to grab and keep every electron from every other atom that he can. He doesn’t
feel good about his selfish nature, but he can’t do anything about it. When you
get two oxygen atoms together, forming oxygen gas (O2), they become
almost criminal in their ruthlessness. Gould does not want this to happen.
Gould
is bonded to a black carbon atom named Chedd, who is calm and loving. Chedd
likes to form bonds, networks of atoms, even giant molecules. But right now
Gould, Chedd, and Elsie (another oxygen atom, whom Gould loves even though he
cannot see or touch her) form a molecule of carbon dioxide (CO2).
Get ready for the carbon dioxide molecule to get sucked into the process of
photosynthesis and end up in the wood of a tree, hidden in the dark until one
day the wood gets chopped by a human poet named Cosmo. Gould ends up in a fire.
The
only way an oxygen atom in carbon dioxide can be freed from the carbon cycle is
by becoming an oxygen radical and joining to an oxygen molecule, making ozone. This
is what happens to Gould. The story ends when Gould, inside an ozone molecule,
is floating high in the air protecting the planet from ultraviolet radiation.
A
surprising fact emerges from this story, one which most writers would overlook.
There are two largely separate cycles in the Earth’s ecosystem. In one, carbon
and oxygen atoms circulate through the food chain by photosynthesis. In
another, oxygen atoms become water, then oxygen again, also by means of
photosynthesis. The only atoms that can cross over between the two cycles is
the occasional oxygen atom. The oxygen atoms in organic molecules produced by
photosynthesis come from carbon dioxide, while the oxygen atoms in the air come
from water. The oxygen atoms very seldom cross from one cycle to the other.
Gould, however, does.
This
story not only explains difficult concepts such as electronegativity but also provides a brief overview of the chemical history of the Earth.
There
are, as in most Rice novels and stories, undercurrents of important issues. In
this case, the oxygen atoms are white and greedy, while the carbon atoms are
black and nice.
