Logarithms are one of the parts of mathematics that often remain a bit mysterious to people, even if they had no difficulty solving problems with them in school. In fact, logarithms are of far broader importance and interest than the narrow applications one usually sees; and seeing this broader picture helps in dispelling some of the mystery and in understanding what they are. In this class we will see new ways of counting, new ways of understanding number and estimating mentally, and new ways of comprehending data, all based in logarithms. I will not be assuming that you know or remember anything about logarithms; part of the point will be to explain them, from the beginning, in a variety of ways.
