In "Electrons and Holes", 1st paragraph, 2nd sentence, "usefull" should be "useful".

Same misspelling in the 2nd paragraph below the first figure.

In the paragraph just before the "Marble in a Tube" figure, next-to-last sentence, "in inthe" needs changing.

In the 2nd sentence below the "Marble in a Tube" figure, "must be move" should be "must be moved".

In the last sentence in this paragraph "appearant" should be "apparent".
