there are waves circling places in this plane where there are no atoms. how do scientists explain that?
STEMs, how do they work ...

>>16785057But the atoms ARE there, just less so.
The dots are carbon monoxide molecules on a copper substrate. Plenty of atoms around.
>>16785057electron cloudthere's non-zero probability that you find electrons away from the atoms, and crests of those waves are where the probability reaches a local maximumeverything is wavy, so there are interference effects too influencing the pattern you see
>>16785057>>16785060>>16785300Correct, the atoms interfere with each other like waves, and their position is uncertain so with a measuring device with high space and time resolution they show up as wave patterns of high intensity (higher counts of detection) and vice versa
>>16785057It looks like very small metallic beads floating on still water that could be resonating at some frequency, though.
>>16785734These are atoms
I would have assumed it was a temporary perturbation or something but nah.Interesting how it stays in the same spot. Goes away when the CO gets near it though. But then returns. Probably an irregularity in the sheet. https://youtube.com/watch?v=oSCX78-8-q0
