MIT Physics Demo -- Microwave Interference
from MIT Department of Physics Technical Services Group May 08, 2008
A double-horn microwave emitter faces a microwave receiver. The receiver is also connected to a speaker, which displays the received signal as audio, and an oscilloscope, which displays the signal visually. When the receiver is moved perpendicularly to the emitter, constructive and destructive interference can be both seen and heard.When one of the emitter horns is covered, the interference pattern disappears.

What Life Factors Contribute to Contracting HIV?
from recent posts - blip.tv (beta) April 04, 2008
In this unscripted interview, Dr. Kuhn discusses the factors patients say contributed to their contracting HIV. Patients have cited rejection by their families, low self-esteem, longing for love, disconnection from their religious community, alienation from God, and boredom as factors contributing to contracting HIV. Recreational use of Viagra and crystal methamphetamine may contribute to further transmission after becoming HIV positive. She also discusses how physicians can more fully contribute to their patients' well-being by talking with them about their lives as a whole and their value as a human being instead of just narrowly focusing on specific symptoms, conditions, and medications.
