Where I come from we call it the ERNST number. Late nineteenth, early twentieth century Austria and Germany produced a crazy number of influential scientists. Of that group Mach conducted important experimental work in compressible flow.

If the 747 is the whale, does that make the A380 the Bigfoot? ;)
