Alternate currents, especially of high frequencies, pass with astonishing freedom through even slightly rarefied gases. The upper strata of the air are rarefied. To reach a number of miles out into space requires the overcoming of difficulties of a merely mechanical nature.

Blockbusters are the exception, not the rule, and yet we see an entire industry through their rarefied air.
Chris (writer) Anderson
Of the great mathematician as an instructor several of his pupils who ventured on the higher planes of the science have written. These were youths who, though they could follow him but a few steps in that rarefied atmosphere, had the privilege of a glimpse now and then into shining infinities wherein this giant sped rejoicing on.
Benjamin Peirce
Art’s true purpose is to be human as opposed to some rarefied activity set away from real life. I think art should help you to navigate the real challenges of being a human being.
Martin Firrell
The work ... abounds in literary, historical and mythological allusions. The sensitivities revealed are far-ranging, capable of fine psychological and sociological analysis, and are as responsive to the contemporary as to the traditional... There is no other writer who, dealing with the struggle between life and death on such a fantastically rarefied level can evoke so much hunger for the stuff of living itself.
Roger Zelazny
With the present importance of the city [of Rome] and the unlimited numbers of its population, it is necessary to increase the number of dwelling-places indefinitely. Consequently, as the ground floors could not admit of so great a number living in the city, the nature of the case has made it necessary to find relief by making the buildings high. In these tall piles reared with piers of stone, walls of burnt brick, and partitions of rubble work, and provided with floor after floor, the upper stories can be partitioned off into rooms to very great advantage. The accommodations within the city walls being thus multiplied as a result of the many floors high in the air, the Roman people easily find excellent places in which to live.
