A special treat for air travelersAs if having sadistic TSA agents at the security checkpoint rummage through our carry-on bags and peering through our clothes using backscatter x-ray machines at the airport was not enough, too often we are served up this little treat aloft.
Martin Rowe's hit song, "Below a Gigahertz"Test & Measurement World's Martin Rowe has come up with yet another Top 16 dB hit, "Below a Gigahertz." It asks the question, "Remember when 50-MHz clock signals were state-of-the-art?"

See videos AP reporter Elliot Minor volunteers to be a test subject - good bottom of page. AP reporter Elliot Minor volunteers.
Man breaking glass with voiceHere is a case of extreme resonance with constructive interference that is destructive. This man breaks a glass with voice. The fatal "blow" is 566 Hz at 105 decibels.
Steve the SlackerMeet "Steve the Slacker." This is actually a Toshiba notebook computer advertisement, but it is a scenario straight out of Dilbert.
E-flite Mini Pulse XT takeoff and landingOK, maybe it is  as bad as being forced to watch home movies, but here is a short clip of my e-powered RC airplane. Here is a clip of the ESC waveform for the brushless motor.
Space Elevator animation, by the Marshal Space Flight CenterThe concept of a Space Elevator has been around for a while, but inept materials technology made it unachievable. Carbon nanotube advances are about to change that. Here is a clip of a contest held for the first competition for working climbing platforms.
Man sets fire to stuff with fingertipsWhereas you and I purposely avoid those painful arcs that come from our fingertips as we touch a doorknob or car door on a cold, low-humidity day, this dude cannot get enough of it. He even likes to light things on fire with arcs from his fingertips.
