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