Richter Scale Day
April 29 is Richter Scale Day, celebrating the birthday of Charles Richter.
The Richter magnitude scale is used worldwide to measure the amount of energy released during earthquakes, particularly smaller, local quakes. Charles Richter and Beno Gutenberg at the California Institute of Technology developed the logarithmic scale in 1935 to study seismic activity in California.
Algebra: In Simplest Terms http://www.learner.org/resources/series66.html * Program 19, "Logarithmic Functions," explains how the Richter scale measures quake magnitude * Program 11, "Circle and Parabola," demonstrates how P and S waves are used to locate an earthquake's epicenter
