Cingular Wireless and Virgin Mobile offer a "rescue call" service: Escape-A-Date. It sounds like an old SNL routine, but according to Cingular:

"This new service allows you to schedule a 'rescue' phone call at a pre-set time. That way, you'll be called at the time you specify. The service tells you exactly what to say to set the tone for a speedy escape. There are eight randomly generated humorous scripts.

With 'Escape-A-Date,' you'll never be at a loss if you need a timely rescue."

The McMath-Pierce Solar Telescope, one of 23 separate telescopes sitting 6,875 above sea level feet atop Arizona's Kitt Peak, is lined with 4.7 miles of water-cooling pipes to keep the optics from vaporizing due to the focused light from the sun.

 

Mystery Connector

If you can identify this connector, please click here to send me an e-mail. Hover your mouse over the image for a description and click on it for a larger view.

Click for larger image. The connector I am interested in is the half on the left. It is a high frequency push-on type. The end is split, and the tapered sleeve slides on the barrel. The right half is an SMA to help in determing the size.

It appears that the original vendor was Micro-Mode, who made the connectors as a special order item for a test cable vendor. Thanks for your participation!

Guesses So Far:

Although not intended to be for fun, you folks have sent in humorous suggestions along with the serious. Some are listed below - thank you.

The earth's magnetic field slightly alters the trajectory of the electron beam in a CRT. The field is strongest at the poles, weakest at the equator, and varies in the direction of polarity everywhere. A CRT adjusted to display properly in Oregon will not look the same in Peru or Italy.

Digging a hole to China is evidently an American kids' thing. From most of the U.S., a hole through the center of the earth leads to the Indian Ocean. An unscientific study by Scientific American magazine shows kids from most other countries never think about what's directly below then. British adults definitely were thinking about it, though, when they named the Antipodes Islands, near  New Zealand, because that point is directly across from Greenwich, England. (antipode = a direct or diametrical opposite). What did middle school boys say they would see if they looked straight down through the earth? "Up girls' skirts."

The curvature employed by Alexandre-Gustave Eiffel of the 986-foot high Eiffel Tower has long intrigued engineers. On a mission to derive an equation for the profile, Patrick Weidman of the University of Colorado discovered an equation in one of Eiffel's notebooks that is an exponential of the natural logarithm - one found frequently in nature. Eiffel figured out that the shape would experience zero wind load on the diagonal elements. Doing so permitted the "lightweight" iron structure to be built with relatively little metal. Its longevity is testimony to its superior design.

Say you are being held captive in a room that is secured by a cipher lock that requires the successful calculation the Xth root of some number Y (X is not an integer). A timer limits your opportunity. A wrong answer gets you a torture session where you are forced to listen to loud Christina Aguilera music. Fortunately, you are an engineer and as such always carry a table of logarithms in your pocket. Your captors, being political science majors, must carry calculators, and think your log table is a track betting sheet, so you can keep it. Could you escape? Click here to find out how.

A young woman, living alone in New York City, was continually having her apartment broken into. Each time there was a break-in she would add one more door lock, but to no avail. At seven locks, she got the bright idea of only locking some of the locks and leaving the others unlocked. It worked! No more break-ins: The burglar would unlock the locked locks, but would lock the unlocked locks.
