The author of How Stuff Works is Marshall Brain. Marshall is the author of ten books and is nationally recognized for his ability to communicate complex ideas clearly. Mr. Brain formerly taught in the Computer Science Department at North Carolina State University, where he was elected to the prestigious Academy of Outstanding Teachers for his work in the classroom. The National Institute of Standards and Technology tells everything about timekeeping here with attractive graphics, excellent text articles, and their own link to the exact time on a page about how time is calibrated. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis.
Tsunamis can savagely attack coastlines, causing devastating property damage and loss of life.
Many of the materials here, like the Great Tsunami section with a page for each of the biggest waves, are created by the University of Washington where the Website is based. This is an outstanding place to study the physics and history of these devastating phenomena, and for students to visit over a period of time to observe science at work. This is an understandable, interactive, online textbook of economics based on a book by Orley M. Amos, Jr., Professor of Economics at Oklahoma State University. Highly readable and annotated by notes in a frame to the right of the main text, the guide is both a useful introduction to economics, and a helpful reference for the initiated. Part of the Poets Corner site, these pages show the photographs, and in some cases paintings, of those we are used to knowing only through their words.
