      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

      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!
