parallel science and other illusions

by Steph • March 7th, 2008

I’m excused from interpreting this talk, Nanometers, Femtoseconds, and Yoctomoles: Molecular-Dynamics Simulations of Diffusion in Garnet, which means I can take notes and play!
The professor is highly billed: Dr. Bill Carlson from UT at Austin. You think I’m kidding about “play”? No way, Jose!
Scale: plates, rocks in the field, mineral grains, atoms….
Geologic Time:
Sizes from macro to nano…..
Diffusion gives direct qualitative information on rates and duration of metamorphic processes. Garnet is present in a wide range of bulk compositions, is stable, and has a wide array of diffusive behaviors that can be monitored to help us understand rates of diffusion and the mechanisms behind them. You know my parallel? Groups (of people) and knowledge/understanding (disseminated via language).
Main topic: Molecular dynamics simulations…. (microdynamic intergroup relations?)
Problem: existing theories for diffusion at atomic scale don’t explain the phenomena we observe…(sounds like social science to me!)
Novel systematics emerge from recent synthesis…
Elastic Strain Theory (EST) – diffusion by vacancy mechanism: work is required to move atoms apart and squeeze this atom in-between them….larger atom = more strain which slows down diffusion. Like all theory (!) “sometimes it works…sometimes it doesn’t.”
There’s a “misfit parameter” (!) = “how badly an atom

researching the edges

I have always felt that the action most worth watching is not at the center of things but where edges meet.

Anne Fadiman. The Spirit Catches You and You Fall Down.
1997. (Preface, p. viii.)
The Review linked above does criticize Fadiman for overromanticizing some aspects of Hmong culture, history, and customs; what reviewer Mai Na M. Lee calls “the bigger issues.” In particular, she criticizes Fadiman’s conclusion that Hmong are “differently ethical.” The phrasing itself is curious, requiring some serious parsing. The way I read the phrase, Fadiman is asserting that ethics are as foundational and valued among the Hmong as within any people. The use of “differently” (instead of the starker label of “different”) – refers to the ethics being performed or based “in a different manner.” It seems to me this opens up comparision on the basis of more, rather then less, similarity. Dr. Lee did not read the phrase this way, interpreting its meaning as more distancing (differencing?) than joining.
Dr. Lee has the benefit of context; I have not yet read that far. There is a Bakhtinian movement discernable here: the counterplay of centripetal and centrifugal forces in the utterances of
