06 August 2004 Wanderings Ralph J. Coppola Come join us on the Wanderings Chat Room. --- (See info and instructions) = = = = = = = = = = = = = = = = = = = = = = = = = = = ===== Feature Wavelets are mathematical tools that can be used in digital signal processing for such fields as Internet communications, engineering, quantum physics and seismic investigations. The following is a sampling of the wavelet resources that can be found on the web.
• Internet Sources of Wavelets • Jacques Lewalle's Tutorial on Continuous Wavelet Analysis of Experimental Data. • Wavelet Basics from Stanford University's STARLab Wavelet Research Group. Wanderings PARRSBORO, N.S. Palaeontologists hope to unearth a complete set of bones from a 200-million-year-old prosauropods before fall tides from the Bay of Fundy damage the site. As a follow up to Forrest's piece, " Dr. John Barnes and his fountain of light ," in the 30 July 2004 of The Citizen Scientist --- an extensive coverage of the green light lidar can be found on the Atmospheric-Optics Laboratory's web site at Dalhousie University, Halifax, NS. They are using the laser to study clouds, climate, air quality, and ozone depletion. NatureWatch is a suite of community based or "citizen science" monitoring programs that demonstrate that volunteers can collect valuable data and contribute to "real science." Let's have another look at John Walker's Fourmilab web site. This site contains quite a few interesting links, such as The Earth and Moon Viewer and an extensive section on The Analytical Engine , Charles Babbage's mechanical digital computer. A "Buckyball" is made up of a collection of 60 carbon atoms arranged in a sphere resembling a soccer ball. The Creative Science Centre was founded to encourage, stimulate and explore the art of DIY experimentation. One of their offerings is a description of a DIY Fullerene (Bucky Ball) Generator. I seem to remember an article, somewhere, that Bucky Balls can be found in candle soot or lamp black (?). [Me, too. Editor.] Some discussion on Bucky Balls can be found on the www.tesla-coil site. Are there any health concerns about working with Bucky Balls? Also, see the International Herald Tribune's article "Nanotechnology Hazards ". Maps, Compasses, & GPS's 101 A Basic Course can be found on the GPS Nuts web site. Here is some more on natural radio and Whistlers. Harold Allen's Natural ELF Whistler Radio -- Part II article offers a good discussion on natural radio and includes links to other related resources. Part I can be viewed in the www.antennax.com archive. The Stephen Hawking Pages contain links to various sites that are devoted to Hawking and his physics. The Kids Room What's up with the SAS LABRats project? Subscribe to the LABRats Newsletter and be kept up to date. The Schlumberger Excellence in Educational Development (SEED) program connects disadvantaged school children in developing countries to the Internet, shares the real world of science through a multilingual online science center, and facilitates collaborative projects among school children around the world. Thousands of questions and answers can be found on the Newton BBS Ask a Scientist Archive page. On The Lighter Side The Mad Scientist in Fact and Fiction See Amara's Stranger than Fiction Department and find out, among other stories, how a marital spat brought CERN to its knees. From The Far Side An update from Wanderings #76 (23 July 2004) --- Maryland's mystery animal has been caught --- AND --- identified. Was it a Chupacabra or just another mangy canine? See the exhumation of the Elmendorf beast. Has Bigfoot
been captured in Maine? Not quite! |
