Students of the past spent most of their academic time in the library, pouring over encyclopedias, and sifting through pages of data. It's easy to get lost in a text-heavy reference book, amidst numbers and figures; this is especially true for science majors, whose art and skill revolves around specific numbers and very precise information.
