That N. can glean meaning from music in such a direct and certain

    kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands. In electrical conductors, these bands are continuous but in insulators and semiconductors there is an "energy gap", in which no electron orbits can exist, between the inner valence band and outer conduction band [Book 1]. Valence electrons help to bind together the atoms in a solid by orbiting 2 adjacent nucleii, while conduction electrons, being less

    least from one another. Frost's use of language reinforces the idea of isolation. When writing about the wall's annual collapse, Frost uses the word "gaps" to describe the holes in the wall. However, this could also stand for the "gaps" that the neighbors are placing between each other.

She is placed in a room, apparently one that was previously inhabited by a mental patient, and

    chains develop as women and as humans. Roots of A Thousand Acres can be seen in numerous novels and plays, the most obvious of which is King Lear.  The parallels are too great to ignore. Smiley is successful because she fills in so many of the gaps left open in the play.  She gives us new and different perspectives.

Additionally, through non- sequiturs, unanswered questions, and narrative gaps, Welty positions the audience behind a screen of sorts--from which a character's "subjective state [is] perceptible but nevertheless impenetrable, something we can see (for a moment) but cannot share" (Pei 417). This idea echoes what Pei proposes as

    weakness the deictic system features. Or if the fax machine just receives the second page of a letter, beginning with "Then he was quite embarrassed about it " - the adressee will never be able to guess what "then", "he" and "it" stands for.

Both gradualists and punctuationists agree that the only explanation for these apparent gaps, besides the notion that there are gaps in the record, would be creationism. Creationism holds that the reason for the appearance of largely different organisms in the fossil record, without organisms that

Something there is that doesn't love a wall, That sends the frozen-ground swell under it, And spills the upper boulders in the sun; And makes gaps even two can pass abreast The above selection of the poem shows how impersonal the wall is.
