Assuming we connect New York with Los Angeles by means of an electronic telecommunication network that operates in strong transmission ranges, as well as with continental satellites, wave guides, bundled coaxial cable, and later also via laser beam fiber optics: the expenditure would be about the same as for a Moon landing, except that the benefits in term of by-products would be greater.

' Most " excimer " lasers are of the noble gas halide type, for which the term excimer is strictly speaking a misnomer ( since a dimer refers to a molecule of two identical or similar parts ): The correct but less commonly used name for such is exciplex laser.

The term also encompassed the basic processes of laser operation where photons are interacting with electrons: absorption, spontaneous emission, and stimulated emission.

In practice, the term dark state is often used for a state that is not accessible by the specific laser in use even though transitions from this state are in principle allowed.

The term " droid ", coined by George Lucas for the original Star Wars film and now used widely within science fiction, originated as an abridgment of " android ", but has been used by Lucas and others to mean any robot, including distinctly non-human form machines like R2-D2.

As a term, critical theory has two meanings with different origins and histories: the first originated in sociology and the second originated in literary criticism, whereby it is used and applied as an umbrella term that can describe a theory founded upon critique ; thus, the theorist Max Horkheimer described a theory as critical in so far as it seeks " to liberate human beings from the circumstances that enslave them.
