Notes for September 10 (Tues.-Thurs. class) and September 14 (Mon.-Wed. class)

Notes on logarithms. While there are other logarithmic scales including pH, we will be focusing on the bel system (usually written in decibels, or tenth of bels, so that 7.1 bels is written as 71 decibels or 71 dB) and the Richter scale, always written to the nearest tenth, like 4.5 or 3.0.
