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 World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

My Hobby Website:
A Step Back to Today
has been around for a really long time; I remember reading it as a kid. A couple
days ago while waiting in a doctor's office, I spied a few editions laying on the
children's play area table and decided to walk over and take a look - just for kicks.
I expected to find the remembered entertainment items like the Hidden Picture with
a dozen or so objects cleverly buried in it to find, Goofus and Gallant demonstrating
good manners and cooperation skills, and the Timbertoes family (I never have understood
them). Everything is still there just as I remembered.
What I did not remember
being there, but was very please to see, were some extremely well-done articles
on many topics of science and engineering. Having begun my engineering studies way
back in 1976 in the field of architecture, reading the piece on Frank Lloyd Wright's
"Fallingwater" house in Pennsylvania was a welcome distraction
while enduring the doctor's waiting room experience. Designed in 1935, it was and
still is an engineering marvel. At the time, reinforced concrete construction was
just gaining acceptance in the world of large commercial buildings, and Wright exploited
the techniques to construct multiple cantilevered platforms that jut out over the
waterfalls over which the house is built. Primary structural beams are anchored
in the natural boulders surrounding the waterfall.
In the same issue was
a story on aviation pioneer Glenn L. Martin. Martin was only a short distance behind
Orville and Oliver Wright in development of powered flight. Indeed, he sought after
and obtained a lot of cooperation from the Wrights. Martin is credited with designing
and flying the first successful monoplane. He went on to found Martin Aircraft Company,
which has since merged to become part of Lockheed Martin. The article covered both
the scientific aspect of his life and the personal side, including the encouragement
he received from his sister. Interestingly, the Wrights also received major encouragement
from their only sister during their own pursuits.
A different edition had
a great article that covered the development of microsensors to detect electrical
sparks, while yet another explored the ecosystem of the Great Lakes. The variety
of topics was impressive, and the depth of coverage was shallow enough to not discourage
young readers, while deep enough to keep me enthusiastically searching for new stories
to the extent that I was almost disappointed (almost) when Melanie finally emerged
from the doctor's examination room an hour after going in. The time spent perusing
Highlights actually made the wait tolerable. If you have children in the
5-16 year-old age range, I definitely recommend signing up for a subscription to
Highlights - you will probably find yourself reading it, too.
