Taking issue with the perception that computer models lack realism, a Sandia National Laboratories researcher told his audience that simulations of the nanoscale provide Rendering of Sandia simulations by Michael Chandross demonstrates significant transfer of material to the probe tip of an atomic force microscope researchers more detailed results — not less — than experiments alone.
The invited talk by Eliot Fang was delivered to members of the Materials Research Society at its recent semi-annual general meeting.
Fang derided the pejorative "garbage in, garbage out" description of computer modeling — the belief that inputs for computer simulations are so generic that outcomes fail to generate the unexpected details found only by actual experiment.
Fang not only denied this truism but reversed it. "There’s another, prettier world beyond what the SEM [scanning electron microscope] shows, and it’s called simulation," he told his audience. "When you look through a microscope, you don’t see some things that modeling and simulation show."
