  Spending a day doing SEM and seeing fuck all then seeing this meme feels targeted

  EM = electromagnetic? Å = a Swedish letter? What am I missing?

    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?

      Exactly this

      This gets worse when talking about cryo EM

    Electron Microscopy. Often used to see very small structures at high resolution. So 1.2 Å is 1.2 angstrom, or 0.12 nm.

    Edit: I should add that often at really high magnification, there is a lot of noise, so the joke is that non EM people would just see static. Not too far from the truth. Practice helps seeing the patterns!

      When do the blondes, brunettes and redheads show up?

    That symbol means Armstrongs, but that’s all I know

      I don’t know if you’re memeing but for anyone else, it’s angstrom (Ångström originally, but the Swedish spelling is not needed or appreciated anymore >:( ), or 0.1 nm, 10^-10 m
