Sorry I just learned seismometers work by the frame with the rotating drum and the sheet of paper and all being shaken by the earthquake, while the stylus and the pen are heavy enough to *not* get shaken right away, and it's like the whole world just reversed on me.
(Yes yes working seismometers are now digital devices but they work on the same principle, the sensor stays still while the thing holding it shakes.)
@Austin_Dern Yep! there's all kinds of weird stuff in sensors--wait until you learn how gravitometers work

@Felthry Yeah, I just had where the action was reversed and that's what's throwing me.
I haven't felt like this since I learned that Pangaea is only the *most recent* time the continents all came together, and that they've broken apart and come back together several times since the crust formed.
@Austin_Dern thinking about things in our field that might elicit a similar reaction
can't seem to think of any though

@Austin_Dern maybe something with atomic force microscopes or liquid crystal hotspotting?

@Felthry They're great names for things, at least! Can say that.
