Not to be snooty but I've been polishing things for a lot of years
now, with the proper equipment :-)


Those were the days a person could frequently learn something from a
bike magazine. Now it's mostly which bike you MUST buy this month, or
which shorts make your legs look sexiest.

Hmmm... I should read some of that. After a triple bypass operation,
where the surgeons borrowed a vein from my leg, I could use some
advice on sexy leg fashions and camouflage. Riding with one leg in
shorts, and the other in full length pants, doesn't seem to attract
the ladies.

In some societies scars were a compliment to male beauty.


Drivel: The same thing happened with Home Power Magazine:
https://www.homepower.com
Originally (1987), it was full of do-it-thyself articles. However, as
grid tied solar became more popular, it's now mostly product reviews,
code compliance, and politics. I still subscribe, but I sometimes
wonder why I bother. The price of success is pollution.

A friend recently recommended "Popular Mechanics" magazine. A
publication that once printed articles about building your own 60 HP
Ford powered midget racer and how to build an arc welder out of an
aircraft alternator, and now publishes articles entitled "does it hurt
to pee on your lawn".

But I do believe that the "modern" (would one say?) type of articles
reflect the interests of the readers. How many people would leave the
comfort of the air conditioned Television Room and the 60 inch TV to
actually get their hands dirty building a midget racer.... or an arc
welder? (Or even know what an arc welder is?)

But the thought comes to mind, are Modern Americans actually intent on
discovering whether one should "pee on the lawn", or not? Sufficiently
so that a national magazine would publish an article concerning what
dirty little boys used to do, with no lessons whatsoever?

One 30-something man that I know is remarkably unschooled in technical
or mechanical things. He recently started reading Popular Mechanics.

I must say, it seems to work for him.
OK, but remember, appearance a predictions in Popular Mechanics is a sure-fire guarantee that it will never come true

Yes, but they're still trying to get it right:

"The Future That Never Was: Pictures from the Past"
http://www.popularmechanics.com/flight/g462/future-that-never-was-next-gen-tech-concepts/
Actually, it looks like they got a few things right.

"110 Predictions For the Next 110 Years" (2012)
http://www.popularmechanics.com/technology/a3120/110-predictions-for-the-next-110-years/
Hmmm... no mention of bicycles in the future. Maybe it will be
replaced by jet or rocket powered backpacks?

I remember, it must have been in the late '40's or '50's that the
Popular Mechanics had an article about flying automobiles and
predicted that we'd all be flying about in our cars.

By the way, a 100 MPG auto is feasible. The record was 149.95 MPG with
a 1947 Studebaker in 1949 which was increased to 376.59 MPG with a
1959 Opel in 1973 and the current world's record is 12,665 mpg (US
gallon) although not set with an automobile that the average man would
want to drive.

I read that the last Calvary charge, or at least the last one engaging
a substantial number of troops was in 1942 when "about 600 Italian
cavalrymen charged some 2,000 Soviet foot soldiers armed with machine
guns and mortars". They apparently charged, using saber and hand
grenades and rode through the Russian formation and then charged back
through the formation to return to their own lines.

Although Slavomir Rawicz may have just made it up[1], his
account of Polish cadets with sabers on horseback against
Panzer tanks is an image for all time.

Exactly where did you think that Hitler got so many Jews to murder?

German. My parents are from Krakow, Poland and had a very different
and unpronounceable last name. After WWII, the only European country
that wasn't totally trashed was Germany, so they emigrated there. I
was born in Munchen, Germany. When we later came to the USA, we took
a German relatives last name. Unfortunately, my parents neglected to
change my first name, which became a problem in skool. When we later
obtained US citizenship, I took the opportunity to change my first
name. After that, I was fully Americanized.

Something like that. I guess the Italians followed the Polish bad
example. I dunno about the hand grenades. Tossing grenades in the
middle of a densely packed cavalry charge, on open ground, is going to
produce collateral damage.

Until I just read the following pages,
https://en.wikipedia.org/wiki/Charge_at_Krojanty
http://www.polamjournal.com/Library/APHistory/Cavalry_Myth/cavalry_myth.html
I had thought that the Polish cavalry really did try to attack German
tanks at the start of WWII. Apparently, this was not true.

Interesting item on that page regarding autumn 1939:
"Each single-turret version of these Polish 7TP tanks
carried a 37mm main gun and up to 17mm of armor plate. They
were superior in both armor and armament to most of the
invading German tanks, and they were the world’s first
diesel powered tanks to see action. "

Yet the richly detailed masterwork _Nomonhon_ [1] says that
at the start of skirmishes in 1938 there were mixed diesel
and gasoline tanks and armored cars on both sides but the
gasoline vehicles proved so fatal to their crews that at the
end, summer 1939, mostly diesel were fielded.

As regards 'action', Zhukov rolled up the Kwantung Army like
a used carpet with 75% casualty rate (45,000 of the
60,000-man force)

While the reality wasn't against tanks, two squadrons, about 250
strong, of the 18th Pomeranian Uhlan Regiment, charged a group of the
German's 76th Infantry Regiment, in a clearing and routed them.

"The charge was successful, the German infantry unit was dispersed,
and the Poles occupied the clearing. However, German armored
reconnaissance vehicles appeared from the forest road, the Polish
units came under heavy machine gun fire and gallop for cover behind a
nearby hillock. "About a third of the Polish force was dead or
wounded. On the other hand, the German advance was halted long enough
to allow the withdrawal of Polish 1st Rifle battalion and National
Defence battalion Czersk from the nearby battle of Chojnice."

In essence, the Calvary charge was a success.
