Flashback 2: Microscopy Lab
Transmission electron (TEM) and scanned probe (SPM) microscopes provide access to atoms, almost one at a time.
TEM’s allow both reciprocal space, and direct, views of atomic structure within solids.
Hull-inspection robots carry SPM’s, which facilitate the “nano-human invasion” of surfaces even by kids!
