6. Schlieren
   `Schlieren` (from German; singular "Schliere", meaning "streak") are optical inhomogeneities in transparent material not visible to the human eye. Schlieren physics developed out of the need to produce high-quality lenses devoid of these inhomogeneities. These inhomogeneities are...
