These items are an archive of past Topical Smorgasbord items that have appeared on the RF Cafe homepage. In keeping with the "cafe"
genre, these tidbits of information are truly a smorgasbord of topics. They all pertain to topics that are related to the general engineering
and science theme of RF Cafe. Note: There is also a huge collection of my 'Factoids' (aka 'Kirt's Cogitations') that might interest you as well.

A few tidbits based on extensive data collection and analysis:
- Highest annual mobile
- Japan became the
1st nation to have

W. Europe @ 10%
- India overtook China
for subscriber growth
- Countries with

Anders Celsius chose his 0° and 100° as the freezing and boiling points of water - makes sense. Where, then did Daniel Fahrenheit come up with
32° and 212° for the same points? It depends on who you ask. Most say 0°F was the coldest available temperature for him in his home of Danzig,
Poland (Dan wanted to avoid negative temperatures, thus his zero point), and 100° represented his body temperature. Conveniently, maybe divinely
in his day, that put the freezing and boiling points of water 180° apart (think reciprocal headings on a compass). Do Google for other theories.
Internet Addiction on the Rise in U.S.

"A Company Called Thompson Ramo Wooldridge"
Well, the way you have been accustomed to reading the slogan is, "A Company Called TRW." I doubt that 1% of TRW employees even know what the
letters stand for - but now you do. The 1958 merger of Thompson with the Ramo-Wooldridge Corporation created the
familiar TRW name.
Magazine Ad Update
If the number of advertisements is an indicator of success, then
Microwave Journal is king among RF engineering magazines.
Penton now owns
RF Design and Microwaves & RF,
so their total ad revenue now combines. My Kirt's Cogitation on magazine advertising
last year tallied the number of pages of text vs. ads for RF magazines. The IMS2006 issue of MWJ topped the revenue intake by far. Here is a
page count for their IMS2007 issue.
Total Page = 370
Full-Page = 197
1/2+ = 51
1/4+ = 42
1/8+ = 12
Total Ads = 63%

The CFL Mercury Onslaught Has Begun
Well, that sure didn't take long. Poor Brandy Bridges, of Maine,
was trying to be green, but dropped a
CFL bulb and broke it on the floor of her daughter's bedroom. To make a long story short, she called
the "authorities" about how to clean the mess. $2,000 paid for the HazMat crew's efforts, but now parts of her house are quarantined with plastic
barriers due to higher than government stipulated mercury vapor levels. Tip: If you break a CFL and want help, call from a public pay phone.
Not Quite So...
(IEEE Spectrum, et al)
You have likely seen this paragraph:

The claim is not as absolute as presented. Consider this version:

Its interpretation is nowhere near as clear even though it follows the proposed rule. A lot of work has been done to debunk the myth.
