Audiophoolery: Pseudoscience in Consumer Audio. You might think that a science-based field like audio engineering would be immune to the kind of magical thinking we see in other fields. Unfortunately, you would be wrong [...] As a consumerist, it galls me to see people pay thousands of dollars for fancy-looking wire that’s no better than the heavy lamp cord they can buy at any hardware store. Or magic isolation pads and little discs made from exotic hardwood that purport to “improve clarity and reduce listening fatigue,” among other surprising claims. The number of scams based on ignorance of basic audio science grows every day. Via.

The HF Active Auroral Research Program (HAARP) (a Google Video) radio signals are clearly heard in the 40 meter band, echoing off the Moon. This video shows S-meter readings as seen on a Yaesu FT-1000MP amateur radio (ham radio) transceiver located in San Jose, California. And of course a thorough explanation of what you are watching/hearing can be found on About the HAARP - LWA Moon Bounce Experiment.

September 30th, 2002, scientists intercepted a 10 minute radio burst from the galactic center, 26,000 Light Years away. 77 minutes passed, and it repeated. And again. The signal repeated 5 times that evening.

Some think those signals are weird mysterious. Others think they are interesting mysterious.

Engines of Our Ingenuity is a web site run by John Lienhard of the University of Houston. The site includes almost 2000 short, three minute talks on the history of science, technology, and engineering. The talks are in the form of RealAudio files, with accompanying transcripts which often give you more links and references. The transcripts themselves are indexed by keywords and are also fully text-searchable. A simple idea but very effective, and kind of addictive. I've been finding out about Jacquard and Babbage, German women astronomers of the seventeenth century, and the deisgn of the zipper. There's also other cool stuff: what did people say about books in 1498?

Jack Kevorkian's lawyer in trouble. He made some negative comments about a few appeals court judges. Not while he was in court, but on a radio talk show. Even so, he could potentially lose his license. His partner said, "Since when is it improper to make comments that are critical of government officials?"
