the ruler so tiny it measures the gaps between atoms themselves
means A unit of length equal to one ten-billionth of a meter (0.1 nanometer), used to measure atomic-scale distances like the spacing of crystals and the wavelengths of light.
from Named for the Swedish physicist Anders Jonas Ångström, a 19th-century pioneer of spectroscopy who mapped the wavelengths of sunlight in tiny fractions of a meter. The unit took his name — Swedish 'ångström' literally meaning roughly 'meadow stream' — and the little ring over the 'Å' is the diacritic English usually drops, leaving us 'angstrom.'
