Noch ein EinschubFoo

:foo: /foo/– Used very generally as a sample name for

absolutely anything, esp. programs and files

– First on the standard list of metasyntactic variables used in syntax examples (bar, baz, qux, quux, corge, grault, garply, waldo, fred, plugh, xyzzy, thud).

The word `foo' had an immediate prewar history in comic strips and cartoons. The earliest documented uses were in the surrealist "Smokey Stover“ comic strip by Bill Holman about a fireman.

EinschubGoogol und Googolplex

GoogolA googol is 10 to the 100th power. The term was invented by Milton Sirotta, the 9-year nephew of mathematician Edward Kasner. A googol is larger than the number of elementary particles in the universe, which amount to only 10 to the 80th power.

GoogolplexA googolplex is 10 to the power of googol. Frank Pilhofer has determined that, given Moore's Law, it would make no sense to try to print out a googleplex for another 524 years - since all earlier attempts to print a googleplex out would be overtaken by the faster processor.
