Winning bidders on many of the auctions were located in countries such as Bulgaria, China, and Russia. Sellers offered to ship "no questions
asked."

A sociology paper from the University of
Oxford has suggested there is a tie between the mindset of Electrical Engineers and that of extreme Islamic terrorists.
"Abstract. We find that graduates from subjects such as science, engineering, and medicine are strongly overrepresented among Islamist
movements in the Muslim world... We also find that engineers alone are strongly over-represented among graduates in violent groups... Do engineers
have a 'mindset' that makes them a particularly good match for Islamism..."
I suggest printing out the entire 90 pages and using
it as bathroom material - not necessarily for reading. |

Yikes, another stalwart of the RF engineering realm has gone the way of Applied Microwave and Wireless, et al! RF Design's
website is still active, but the last monthly published edition was February 2008.
"RF Design is no longer published as a stand alone
magazine. The magazine will be published quarterly and mailed to subscribers of Microwaves & RF  magazine."
Adieu, and farewell.

China is Doing Things in a Big Way
|
|
China is home to the world's largest shopping mall: the 7,000,000 ft2
South China Mall; the world's longest sea-crossing bridge
- the 32 km-long span over the East China Sea;
the world's largest hydroelectric dam - the Three Gorges Dam project;
and the world's highest railroad - the Qingzang Railway crossing
the Tibetan permafrost 5 km above sea level; and now the world's largest airport - the
Feng-Shui-compliant Beijing International Airport, which
covers 2x the area of the Pentagon. That's a lot of resources and huge carbon footprints - good thing for them that they are a "developing country"
and are not subject to the Kyoto Protocol. |

It's Not Your Father's World

Remember the old saying, "If you snooze, you lose?" Well... |
|
Then: ¼ of mankind lived under the British flag in the largest empire the world had ever
known; many parts not under Britain's rule had been created by her. Britain dominated worldwide science, manufacturing and trade. |
|
Now: The IMF just warned that the West faces the largest financial shock
since the Great Depression, while Asian economies (mainly China & India) are powering ahead. China spends 35x as much on crude oil as it
did in year 2000, and 23x as much on copper. ½ of the world's new buildings are being built in China. As it builds endless rows of skyscrapers
on former farm lands, China consumes ½ the world's cement and a 1/3 of its steel.

The General Relativity Einstein/Essen Anniversary Test was conducted in September of 2005 by
Daniel Kleppner and his kids. They took several very accurate cesium atomic clocks from home and parked 5,400 feet up Mt. Rainier for a full
two days. The goal was to see if the clocks actually gained time as predicted by Einstein's general theory of relativity. Gravity at 5,400 feet
is less (by about 0.1%) than at home at 1,035 feet, and therefore the clocks should run 22 ns faster over the two days.
 Did they? The plot to the left shows the results. Click on the image for full details.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas
and reference material while performing my work as an RF system and circuit design engineer.
The Internet was still largely an unknown entity at the time and not much was available
in the form of WYSIWYG
