Comment on 1.2 Å

I think this is referring to electron microscopy, and å is a unit for 10^-10^ meters. Electron microscopy can be very noisy and it is hard to distinguish objects

Angstroms hurt my brain. A $10^{-10}$ of a metre, but not a nanometre or a picometre. Just…why?

  … However, they soon realized that the definition of the metre at the time, based on a material artifact, was not accurate enough for their work. So, around 1907 they defined their own unit of length, which they called “Ångström”, based on the wavelength of a specific spectral line. It was only in 1960, when the metre was redefined in the same way, that the angstrom became again equal to 10^10 metre. Wikipedia

Exactly this

This gets worse when talking about cryo EM
