|How Big Are Things?
|nanometer's Room - looking at a sheet of graph paper|
|look at the entire room||
atom ~1 nm|
ribosome ~10 nm
... DNA helix (think coffee stirrer)

approximate smallest virus src
O2 and N2's mean free path in STP air. src,src(PS),src
H2O's mean free path in STP water. (order 0.1 nm!)
X-Rays (shortest wavelength is ~0.03 nm) [soft vs hard]
. . . Ultra-Violet wavelengths (up to ~400 nm)
Extreme UltraViolet (EUV)
Deep UltraViolet (DUV) [I'm not sure that DUV doesn't overlap UVC]
