The central point of the story is a world without time, without which the story would have no point - none of it would have happened, and it would be just like our world

    The Disillusionment of Ten O'Clock, what a time of night! "The houses are haunted by white night-gowns." Everything is the same from one house to the next. Not only does Wallace Stevens hint at the Disillusionment of Ten O'Clock, he also brings forth feelings of loneliness and despair through his select use of neutral diction. Stevens emphasizes neutral diction using parallelism and repetition, the sameness of the syntax, and an ironic change in wording. Nevertheless, the emotion of the poem is only

    the '22'. The Cray operates at a clock rate of 105 MHz (the regular, run-of-the-mill IBMPC has a clock rate of 4.77 MHz). By quick calculations, you would be led to believe the Cray is only about 20 times faster that the PC. Obviously, this is not the case. The Cray handles data considerably differently than the PC. The Cray's circuits permit an array of data (known as a 'vector') to be processes as a SINGLE entity. So, where the IBMPC may require several clock cycles to multiply two numbers, the
