When Can We Add Atomic Images Together?
An evidence-synchronized visual guide to when HAADF-STEM atomic responses can be added, how geometry changes non-additivity, and when higher image order is needed.
When Is Independent Atomic Addition Enough in HAADF-STEM?
This earlier teaching article has been superseded by the evidence-synchronized tutorial When Can We Add Atomic Images Together?
When Can You Trust a Faster Scientific Model?
A practical question in scientific computing is when a faster approximation can be trusted. This post outlines a validation framework using atomic-resolution STEM surrogate models as an example.
