The number of statements
uttered verbally and/or in print is uncountable. Some are more noteworthy than others either
because of sheer brilliance, good humor, or utter inanity. We all hope our own remembered
words, if any, fall into one of the first two categories rather than the third. I do a lot
of reading and find many notable quotes to use that fit the theme of RF Cafe; they fall into
all three categories. I always try to verify quotes from original sources or at least from
printed books like
The Experts Speak, of which I own a hard copy. Enjoy.

was neither particle nor wave, but a bit of both - a wavicle." - Ian Stewart, in
Pursuit of the Unknown: 17 Equations That Changed the World," 2012, regarding
the dual nature of light as covered in the chapter on
for wave functions. BTW, the real term used is "wave–particle duality,"
which is a quantum mechanical principle stating that all matter–energy has both
a wave and a particle nature. The wave behavior of light is exhibited in its ability
to be diffracted at a sharp edge. It is the particle nature which accounts for the

On May 21st, 2010, in an interview with CBS News entitled, "The Cell Phone:
Marty Cooper's Big Idea," cell phone inventor
Martin Cooper, was asked, "Isn't
there almost a Brave New World sensibility behind all of this being connected?
What does it do to our privacy?" His reply: "Sorry. Privacy is a thing of the
past." There are two aspects of that loss of privacy. One is the vulnerability
of data collection by anyone with the technology (including Big Brother). The other
aspect is loss of privacy by choice due to people blabbing all their business in
public where anyone nearby can hear. The former is unavoidable by the cell phone
user, while the latter is completely avoidable - and preferable, since almost
nobody want to hear you yak about your personal business.

November 2019 issue of Astronomy magazine included an interview with
moon-walking astronauts Alan Bean and Pete Conrad. It is the 50th anniversary of
the world's second manned excursion to the moon's surface on November 19, 1969.
Amongst the science experiments and tasks to be performed was the deployment of
a plutonium fuel cell that would power the equipment remaining on the surface after
the Lunar Module blasted off. Most of the gear had been set up without incident,
but the fuel rod got stuck inside its transport cylinder. None of that science gear
would be of any use with out a power supply. After unsuccessfully trying to free
the rod without risking damage, it finally came down to whacking it with one of
$400 NASA hammers to get it out. Bean's comment to Houston upon completion was,
come to the Moon without a hammer."

The November 2019 issue of
QST (login required) is chock full of great articles. The one entitled,
"Indoor Antennas for VHF Weak-Signal Work," written by Mr. Les Rayburn (N1LF)
discusses ways to stealthily mount an antenna in your attic in order to work around
HOA restrictions and/or to protect your installation from weather abuse. Considering
the close proximity to living quarters, he offers caveats and mitigation suggestions
regarding RF exposure during transmission and subjection to high noise levels from
his own home and from nearby neighbors. The notable line pulled from the article
is, "Neighbors equal noise." The situation gets worse every day. Here's my own

"It was made clear that I was not to touch
this sacred totem, especially the threaded rods..." - Steve Ford, WB8IMY, in an
article entitled, "Duplexers &
Diplexers," in the October 2019 issue of QST magazine. That statement
was made in regard to a cavity-tuned duplexer that was part of a Ham radio repeater
installation. Mr. Ford, a monthly columnist, discusses the difference between
a duplexer and a diplexer. A pull quote from the piece is, "If you're about to pay
less than $100 for the device in question, it is a diplexer. If the price tag has
four digits to the left of the decimal, it is a duplexer." Do you agree with that
generalization? Unfortunately, the ARRL does not make the magazine articles available

to watch the momentous event on TV as it was broadcast live from the moon on a Sunday

As we approach the 50th anniversary of the
Apollo 11 moon landing, many magazines are publishing articles about the event
and the background leading up to it. I have tagged a couple notable quotes from
astronauts involved that will be posted over the next month or so. The June issue
of Discover magazine included this one as delivered by
to the National Press Club: "I am, and ever will be, a white-socks, pocket-protector,
nerdy engineer, born under the second law of thermodynamics, steeped in the steam
tables, in love with free-body diagrams. ... Science is about what is. Engineering
is about what can be." Amen, bro.
"It's what you learn after you know it all that counts." -
Wernher Magnus Maximilian, Freiherr von Braun,
chief designer of the
rocket that terrorized London in the 1940s and chief architect of the
rocket that launched the first men to the moon in the 1960s, is quoted as saying,
"The best computer is a man, and it's the only one that can be mass-produced by
unskilled labor." von Braun was one of many German scientists conscripted to
National Socialist German Workers Party (aka Nazi) regime's bidding during World
War II - formally an Schutzstaffel (aka
SS) officer. He and his
surrendered to the Americans in 1945 after escaping to Austria when the end
of the Third Reich was imminent. His willingness to be part of the Nazi German war
effort is fuzzy; therefore, I have a hard time fully appreciating his significant
contributions to the U.S. space program. Reportedly, von Braun experienced
religious conversion that changed his life.
Notable Quote by Albert Bandura on

filtering I did try would just add loss, but I knew the station went off the air
for 'regularly scheduled maintenance' so I just waited until they were off the air
and the band was wide open! If you want to pick nits, I guess you could say that
I filtered that station in the time domain instead of the frequency domain." Brilliant ...
