Since the Supreme Court's decision of that year this is more doubtful ; ;

( Since the time-span of the nation-state coincides roughly with the separate existence of the United States as an independent entity, it is perhaps natural for Americans to think of the nation as representative of the highest form of order, something permanent and unchanging.

Since the difficulty of drawing the net is great, we will merely discuss it.

Since a civilizational crisis involves also a crisis in private interests and in the ruling class, reaction is normally found among those who feel themselves to be among the ruling class.

Since the great flood of these dystopias has appeared only in the last twelve years, it seems fairly reasonable to assume that the chief impetus was the 1949 publication of Nineteen Eighty-Four, an assumption which is supported by the frequent echoes of such details as Room 101, along with education by conditioning from Brave New World, a book to which science-fiction writers may well have returned with new interest after reading the more powerful Orwell dystopia.

Since the goal of our international planners is a World Government, this Atlantic Community would mark a giant step in that direction for, once American economic autonomy is absorbed, a larger grouping is a question of time.

* Since a ship traveling at impulse velocities ( slower than, but approaching, the speed of light ) is still traveling in the normal space-time continuum, concerns of time dilation apply, so high relativistic speeds are avoided unless absolutely necessary ; impulse power is therefore customarily limited to a maximum of ¼ lightspeed.

Since rainbows are actually a continuum of color, there are no empirical stripes or bands, and yet people see as many bands as their language possesses primary color words.

Since the distinction is geographical, the two situations ( learning second language and learning foreign language ) can be considered as a continuum.

Since it is possible to adapt, expand, update, or otherwise customise any PC within the limits of the PCs conformance to standard component interfaces, homebuilt PC systems form a continuum from standard system suppliers offerings adapted with an alternative video card or uprated hard disk, up to systems built from scratch from components, owing nothing to any specific system assembler.
