Obsidian, by default, provides the capability to trace backlinks in the right pane. So all thus-far identified concepts (machines, phenomena, laws) which invoke resonance as incident, presumably meriting a Bode plot or such, can quickly be listed out.
Additionally, if you have loaded the map into Obsidian and allowed add-ons, you can press "Ctrl+P" type "path" and use the "Path Finder" facility to quickly brainstorm things[0] for example, how resonance is related to health and safety.
